  • JavaScript Intellisense with Telerik in ASP.NET Master Page Project with VS 2010

    - by Otto Neff
    Today I was looking for a solution to get finally the JScript/Javascript/jQuery Intellisense Featureworking with my ASP.Net Webform Project to work. I found some good articles: - JScript IntelliSense Overview- JScript IntelliSense: A Reference for the “Reference” Tag- Enabling JavaScript intellisense in VS.NET 2010 to work with SharePoint 2010- Rich IntelliSense for jQueryBUT, all of suggested solutions did not work right with my Master Page based Visual Studio 2010 Solution.Only with physical Javascript Files (Telerik includes certain Javascript Files like jQuery as Ressource) or/andconfigure always a new ASP.NET Scriptmanager / RadScriptManager on every page derived from the Master Page, wasn't exactly what I was looking for. So I came up with the following simple Solution, to Trick VS2010and still have the Project running with multiple runat="server" Scriptmanagers. In short:- New ASP.NET control derived from ScriptManager with emtpy overwritten OnInit() to use it as emtpy wrapper for VS2010. In detail:New RadScriptManager Classusing System; using System.Collections.Generic; using System.Linq; using System.Web; using Telerik.Web.UI; namespace IntellisenseJavascript.Controls { public class IntelliJS : RadScriptManager { protected override void OnInit(EventArgs e) { } protected override void OnPreRender(EventArgs e) { } protected override void OnLoad(EventArgs e) { } protected override void Render(System.Web.UI.HtmlTextWriter writer) { } public override void RenderControl(System.Web.UI.HtmlTextWriter writer) { } } } web.config<configuration> ... <system.web> ... <pages> <controls> <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI, Version=2011.3.1115.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4"/> <add tagPrefix="VSFix" namespace="IntellisenseJavascript.Controls" assembly="IntellisenseJavascript"/> </controls> </pages> ...

  • Windows Azure: Announcing release of Windows Azure SDK 2.2 (with lots of goodies)

    - by ScottGu
    Earlier today I blogged about a big update we made today to Windows Azure, and some of the great new features it provides. Today I’m also excited to also announce the release of the Windows Azure SDK 2.2. Today’s SDK release adds even more great features including: Visual Studio 2013 Support Integrated Windows Azure Sign-In support within Visual Studio Remote Debugging Cloud Services with Visual Studio Firewall Management support within Visual Studio for SQL Databases Visual Studio 2013 RTM VM Images for MSDN Subscribers Windows Azure Management Libraries for .NET Updated Windows Azure PowerShell Cmdlets and ScriptCenter The below post has more details on what’s available in today’s Windows Azure SDK 2.2 release.  Also head over to Channel 9 to see the new episode of the Visual Studio Toolbox show that will be available shortly, and which highlights these features in a video demonstration. Visual Studio 2013 Support Version 2.2 of the Window Azure SDK is the first official version of the SDK to support the final RTM release of Visual Studio 2013. If you installed the 2.1 SDK with the Preview of Visual Studio 2013 we recommend that you upgrade your projects to SDK 2.2.  SDK 2.2 also works side by side with the SDK 2.0 and SDK 2.1 releases on Visual Studio 2012: Integrated Windows Azure Sign In within Visual Studio Integrated Windows Azure Sign-In support within Visual Studio is one of the big improvements added with this Windows Azure SDK release.  Integrated sign-in support enables developers to develop/test/manage Windows Azure resources within Visual Studio without having to download or use management certificates.  You can now just right-click on the “Windows Azure” icon within the Server Explorer inside Visual Studio and choose the “Connect to Windows Azure” context menu option to connect to Windows Azure: Doing this will prompt you to enter the email address of the account you wish to sign-in with: You can use either a Microsoft Account (e.g. Windows Live ID) or an Organizational account (e.g. Active Directory) as the email.  The dialog will update with an appropriate login prompt depending on which type of email address you enter: Once you sign-in you’ll see the Windows Azure resources that you have permissions to manage show up automatically within the Visual Studio Server Explorer (and you can start using them): With this new integrated sign in experience you are now able to publish web apps, deploy VMs and cloud services, use Windows Azure diagnostics, and fully interact with your Windows Azure services within Visual Studio without the need for a management certificate.  All of the authentication is handled using the Windows Azure Active Directory associated with your Windows Azure account (details on this can be found in my earlier blog post). Integrating authentication this way end-to-end across the Service Management APIs + Dev Tools + Management Portal + PowerShell automation scripts enables a much more secure and flexible security model within Windows Azure, and makes it much more convenient to securely manage multiple developers + administrators working on a project.  It also allows organizations and enterprises to use the same authentication model that they use for their developers on-premises in the cloud.  It also ensures that employees who leave an organization immediately lose access to their company’s cloud based resources once their Active Directory account is suspended. Filtering/Subscription Management Once you login within Visual Studio, you can filter which Windows Azure subscriptions/regions are visible within the Server Explorer by right-clicking the “Filter Services” context menu within the Server Explorer.  You can also use the “Manage Subscriptions” context menu to mange your Windows Azure Subscriptions: Bringing up the “Manage Subscriptions” dialog allows you to see which accounts you are currently using, as well as which subscriptions are within them: The “Certificates” tab allows you to continue to import and use management certificates to manage Windows Azure resources as well.  We have not removed any functionality with today’s update – all of the existing scenarios that previously supported management certificates within Visual Studio continue to work just fine.  The new integrated sign-in support provided with today’s release is purely additive. Note: the SQL Database node and the Mobile Service node in Server Explorer do not support integrated sign-in at this time. Therefore, you will only see databases and mobile services under those nodes if you have a management certificate to authorize access to them.  We will enable them with integrated sign-in in a future update. Remote Debugging Cloud Resources within Visual Studio Today’s Windows Azure SDK 2.2 release adds support for remote debugging many types of Windows Azure resources. With live, remote debugging support from within Visual Studio, you are now able to have more visibility than ever before into how your code is operating live in Windows Azure.  Let’s walkthrough how to enable remote debugging for a Cloud Service: Remote Debugging of Cloud Services To enable remote debugging for your cloud service, select Debug as the Build Configuration on the Common Settings tab of your Cloud Service’s publish dialog wizard: Then click the Advanced Settings tab and check the Enable Remote Debugging for all roles checkbox: Once your cloud service is published and running live in the cloud, simply set a breakpoint in your local source code: Then use Visual Studio’s Server Explorer to select the Cloud Service instance deployed in the cloud, and then use the Attach Debugger context menu on the role or to a specific VM instance of it: Once the debugger attaches to the Cloud Service, and a breakpoint is hit, you’ll be able to use the rich debugging capabilities of Visual Studio to debug the cloud instance remotely, in real-time, and see exactly how your app is running in the cloud. Today’s remote debugging support is super powerful, and makes it much easier to develop and test applications for the cloud.  Support for remote debugging Cloud Services is available as of today, and we’ll also enable support for remote debugging Web Sites shortly. Firewall Management Support with SQL Databases By default we enable a security firewall around SQL Databases hosted within Windows Azure.  This ensures that only your application (or IP addresses you approve) can connect to them and helps make your infrastructure secure by default.  This is great for protection at runtime, but can sometimes be a pain at development time (since by default you can’t connect/manage the database remotely within Visual Studio if the security firewall blocks your instance of VS from connecting to it). One of the cool features we’ve added with today’s release is support that makes it easy to enable and configure the security firewall directly within Visual Studio.  Now with the SDK 2.2 release, when you try and connect to a SQL Database using the Visual Studio Server Explorer, and a firewall rule prevents access to the database from your machine, you will be prompted to add a firewall rule to enable access from your local IP address: You can simply click Add Firewall Rule and a new rule will be automatically added for you. In some cases, the logic to detect your local IP may not be sufficient (for example: you are behind a corporate firewall that uses a range of IP addresses) and you may need to set up a firewall rule for a range of IP addresses in order to gain access. The new Add Firewall Rule dialog also makes this easy to do.  Once connected you’ll be able to manage your SQL Database directly within the Visual Studio Server Explorer: This makes it much easier to work with databases in the cloud. Visual Studio 2013 RTM Virtual Machine Images Available for MSDN Subscribers Last week we released the General Availability Release of Visual Studio 2013 to the web.  This is an awesome release with a ton of new features. With today’s Windows Azure update we now have a set of pre-configured VM images of VS 2013 available within the Windows Azure Management Portal for use by MSDN customers.  This enables you to create a VM in the cloud with VS 2013 pre-installed on it in with only a few clicks: Windows Azure now provides the fastest and easiest way to get started doing development with Visual Studio 2013. Windows Azure Management Libraries for .NET (Preview) Having the ability to automate the creation, deployment, and tear down of resources is a key requirement for applications running in the cloud.  It also helps immensely when running dev/test scenarios and coded UI tests against pre-production environments. Today we are releasing a preview of a new set of Windows Azure Management Libraries for .NET.  These new libraries make it easy to automate tasks using any .NET language (e.g. C#, VB, F#, etc).  Previously this automation capability was only available through the Windows Azure PowerShell Cmdlets or to developers who were willing to write their own wrappers for the Windows Azure Service Management REST API. Modern .NET Developer Experience We’ve worked to design easy-to-understand .NET APIs that still map well to the underlying REST endpoints, making sure to use and expose the modern .NET functionality that developers expect today: Portable Class Library (PCL) support targeting applications built for any .NET Platform (no platform restriction) Shipped as a set of focused NuGet packages with minimal dependencies to simplify versioning Support async/await task based asynchrony (with easy sync overloads) Shared infrastructure for common error handling, tracing, configuration, HTTP pipeline manipulation, etc. Factored for easy testability and mocking Built on top of popular libraries like HttpClient and Json.NET Below is a list of a few of the management client classes that are shipping with today’s initial preview release: .NET Class Name Supports Operations for these Assets (and potentially more) ManagementClient Locations Credentials Subscriptions Certificates ComputeManagementClient Hosted Services Deployments Virtual Machines Virtual Machine Images & Disks StorageManagementClient Storage Accounts WebSiteManagementClient Web Sites Web Site Publish Profiles Usage Metrics Repositories VirtualNetworkManagementClient Networks Gateways Automating Creating a Virtual Machine using .NET Let’s walkthrough an example of how we can use the new Windows Azure Management Libraries for .NET to fully automate creating a Virtual Machine. I’m deliberately showing a scenario with a lot of custom options configured – including VHD image gallery enumeration, attaching data drives, network endpoints + firewall rules setup - to show off the full power and richness of what the new library provides. We’ll begin with some code that demonstrates how to enumerate through the built-in Windows images within the standard Windows Azure VM Gallery.  We’ll search for the first VM image that has the word “Windows” in it and use that as our base image to build the VM from.  We’ll then create a cloud service container in the West US region to host it within: We can then customize some options on it such as setting up a computer name, admin username/password, and hostname.  We’ll also open up a remote desktop (RDP) endpoint through its security firewall: We’ll then specify the VHD host and data drives that we want to mount on the Virtual Machine, and specify the size of the VM we want to run it in: Once everything has been set up the call to create the virtual machine is executed asynchronously In a few minutes we’ll then have a completely deployed VM running on Windows Azure with all of the settings (hard drives, VM size, machine name, username/password, network endpoints + firewall settings) fully configured and ready for us to use: Preview Availability via NuGet The Windows Azure Management Libraries for .NET are now available via NuGet. Because they are still in preview form, you’ll need to add the –IncludePrerelease switch when you go to retrieve the packages. The Package Manager Console screen shot below demonstrates how to get the entire set of libraries to manage your Windows Azure assets: You can also install them within your .NET projects by right clicking on the VS Solution Explorer and using the Manage NuGet Packages context menu command.  Make sure to select the “Include Prerelease” drop-down for them to show up, and then you can install the specific management libraries you need for your particular scenarios: Open Source License The new Windows Azure Management Libraries for .NET make it super easy to automate management operations within Windows Azure – whether they are for Virtual Machines, Cloud Services, Storage Accounts, Web Sites, and more.  Like the rest of the Windows Azure SDK, we are releasing the source code under an open source (Apache 2) license and it is hosted at https://github.com/WindowsAzure/azure-sdk-for-net/tree/master/libraries if you wish to contribute. PowerShell Enhancements and our New Script Center Today, we are also shipping Windows Azure PowerShell 0.7.0 (which is a separate download). You can find the full change log here. Here are some of the improvements provided with it: Windows Azure Active Directory authentication support Script Center providing many sample scripts to automate common tasks on Windows Azure New cmdlets for Media Services and SQL Database Script Center Windows Azure enables you to script and automate a lot of tasks using PowerShell.  People often ask for more pre-built samples of common scenarios so that they can use them to learn and tweak/customize. With this in mind, we are excited to introduce a new Script Center that we are launching for Windows Azure. You can learn about how to scripting with Windows Azure with a get started article. You can then find many sample scripts across different solutions, including infrastructure, data management, web, and more: All of the sample scripts are hosted on TechNet with links from the Windows Azure Script Center. Each script is complete with good code comments, detailed descriptions, and examples of usage. Summary Visual Studio 2013 and the Windows Azure SDK 2.2 make it easier than ever to get started developing rich cloud applications. Along with the Windows Azure Developer Center’s growing set of .NET developer resources to guide your development efforts, today’s Windows Azure SDK 2.2 release should make your development experience more enjoyable and efficient. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • ASP.NET Multi-Select Radio Buttons

    - by Ajarn Mark Caldwell
    “HERESY!” you say, “Radio buttons are for single-select items!  If you want multi-select, use checkboxes!”  Well, I would agree, and that is why I consider this a significant bug that ASP.NET developers need to be aware of.  Here’s the situation. If you use ASP:RadioButton controls on your WebForm, then you know that in order to get them to behave properly, that is, to define a group in which only one of them can be selected by the user, you use the Group attribute and set the same value on each one.  For example: 1: <asp:RadioButton runat="server" ID="rdo1" Group="GroupName" checked="true" /> 2: <asp:RadioButton runat="server" ID="rdo2" Group="GroupName" /> With this configuration, the controls will render to the browser as HTML Input / Type=radio tags and when the user selects one, the browser will automatically deselect the other one so that only one can be selected (checked) at any time. BUT, if you user server-side code to manipulate the Checked attribute of these controls, it is possible to set them both to believe that they are checked. 1: rdo2.Checked = true; // Does NOT change the Checked attribute of rdo1 to be false. As long as you remain in server-side code, the system will believe that both radio buttons are checked (you can verify this in the debugger).  Therefore, if you later have code that looks like this 1: if (rdo1.Checked) 2: { 3: DoSomething1(); 4: } 5: else 6: { 7: DoSomethingElse(); 8: } then it will always evaluate the condition to be true and take the first action.  The good news is that if you return to the client with multiple radio buttons checked, the browser tries to clean that up for you and make only one of them really checked.  It turns out that the last one on the screen wins, so in this case, you will in fact end up with rdo2 as checked, and if you then make a trip to the server to run the code above, it will appear to be working properly.  However, if your page initializes with rdo2 checked and in code you set rdo1 to checked also, then when you go back to the client, rdo2 will remain checked, again because it is the last one and the last one checked “wins”. And this gets even uglier if you ever set these radio buttons to be disabled.  In that case, although the client browser renders the radio buttons as though only one of them is checked the system actually retains the value of both of them as checked, and your next trip to the server will really frustrate you because the browser showed rdo2 as checked, but your DoSomething1() routine keeps getting executed. The following is sample code you can put into any WebForm to test this yourself. 1: <body> 2: <form id="form1" runat="server"> 3: <h1>Radio Button Test</h1> 4: <hr /> 5: <asp:Button runat="server" ID="cmdBlankPostback" Text="Blank Postback" /> 6: &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 7: <asp:Button runat="server" ID="cmdEnable" Text="Enable All" OnClick="cmdEnable_Click" /> 8: &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 9: <asp:Button runat="server" ID="cmdDisable" Text="Disable All" OnClick="cmdDisable_Click" /> 10: &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 11: <asp:Button runat="server" ID="cmdTest" Text="Test" OnClick="cmdTest_Click" /> 12: <br /><br /><br /> 13: <asp:RadioButton ID="rdoG1R1" GroupName="Group1" runat="server" Text="Group 1 Radio 1" Checked="true" /><br /> 14: <asp:RadioButton ID="rdoG1R2" GroupName="Group1" runat="server" Text="Group 1 Radio 2" /><br /> 15: <asp:RadioButton ID="rdoG1R3" GroupName="Group1" runat="server" Text="Group 1 Radio 3" /><br /> 16: <hr /> 17: <asp:RadioButton ID="rdoG2R1" GroupName="Group2" runat="server" Text="Group 2 Radio 1" /><br /> 18: <asp:RadioButton ID="rdoG2R2" GroupName="Group2" runat="server" Text="Group 2 Radio 2" Checked="true" /><br /> 19:  20: </form> 21: </body> 1: protected void Page_Load(object sender, EventArgs e) 2: { 3:  4: } 5:  6: protected void cmdEnable_Click(object sender, EventArgs e) 7: { 8: rdoG1R1.Enabled = true; 9: rdoG1R2.Enabled = true; 10: rdoG1R3.Enabled = true; 11: rdoG2R1.Enabled = true; 12: rdoG2R2.Enabled = true; 13: } 14:  15: protected void cmdDisable_Click(object sender, EventArgs e) 16: { 17: rdoG1R1.Enabled = false; 18: rdoG1R2.Enabled = false; 19: rdoG1R3.Enabled = false; 20: rdoG2R1.Enabled = false; 21: rdoG2R2.Enabled = false; 22: } 23:  24: protected void cmdTest_Click(object sender, EventArgs e) 25: { 26: rdoG1R2.Checked = true; 27: rdoG2R1.Checked = true; 28: } 29: 30: protected void Page_PreRender(object sender, EventArgs e) 31: { 32:  33: } After you copy the markup and page-behind code into the appropriate files.  I recommend you set a breakpoint on Page_Load as well as cmdTest_Click, and add each of the radio button controls to the Watch list so that you can walk through the code and see exactly what is happening.  Use the Blank Postback button to cause a postback to the server so you can inspect things without making any changes. The moral of the story is: if you do server-side manipulation of the Checked status of RadioButton controls, then you need to set ALL of the controls in a group whenever you want to change one.

  • ASP.NET Authentication Cookie timout and IIS 7 setting

    - by David Laplante
    Hello, I have an ASP.NET website for which i've set the authetication timeout to 60 days so that my users don't have to log in each time they come back if they checked the "remember me" option. Basic ASP.NET login mechanism... It's working fine on my developpement server as well as on the visual studio built-in web server. I can close the browser, wait around 30-40 minutes and browse back to the site and be automatically logged in. However, I've not moved the site to a hosting provider and it seems that whatever I do to my Web.config file, the cookie expires after around 30 minutes (hard to tell the exact amount of time). I have asked the provider's help support and they basically told me: "Web.config file is to configure your website. Please do not change it if you don't know what you are doing" Frustrating answer indeed... To be sure, I checked everywhere on the net for exceptions, fine prints, in the basic asp.net authentication but found none. I have access to IIS remote management for my site (IIS 7) but don't really know where to look. Can there be something in the IIS setting that is overriding my web.config authentication setting? What should I do... Thanks for you help!

  • ASP.NET 2.0 and COM Port Communication

    - by theaviator
    ASP.NET 2.0 and COM Port Communication Hello Guys, I have a managed DLL which communicates with the devices attached on COM/Serial ports. The desktop Winforms application sends requests on ports and receives/stores data in memory. In Winforms app I have added a reference to DLL and I am using the methods. This works well. Now, there is a situation where I need to show this data from serial/com port on a web-page. And also users should be able to send requests to the ports using this DLL. I have made a web app in ASP.NET (2.0). Added a reference to the DLL. I am able to use this DLL, the DLL communicates on the COM upon button click on web-page and also the response is shown on web page. However I am not happy with the approach and strongly feel that this is a bad approach. Also the development server crashes after 3 -4 requests. What is the best approach in this scenario. If I use a windows service then how would my ASP.net app will communicate with the Weindows service. Or can this be easily done using WCF. I have not used WCF any time nor any of .net remoting technique. Please suggest me the best architecture in this scenario. Thank you

  • ApplicationPoolIdentity permissions on Temporary Asp.Net files

    - by Anton
    Hi all, at work I am struggling a bit with the following situation: We have a web application that runs on a WIndows Server 2008 64 bits machine. The app's ApplicationPool is running under the ApplicationPoolIdentity and configured for .net 2 and Classic pipeline mode. This works fine up to the moment that XmlSerialization requires creation of Serializer assemblies where MEF is being used to create a collection of knowntypes. To remedy this I was hoping that granting the ApplicationPoolIdentity rights to the ASP.Net Temporary Files directory would be enough, but alas... What I did was the run the following command from a cmd prompt: icacls "c:\windows\microsoft.net\framework64\v2.0.50727\Temporary ASP.NET Files" /grant "IIS AppPool\MyAppPool":(M) Obviously this did not work, otherwise you would not be reading this :) Strange thing is that whenever I grant the Users or even more specific, the Authenticated Users Group those permissions, it works. What's weird as well (in my eyes) is that before I started granting access the ApplicationPoolIdentity was already a member of IIS_IUSRS which does have Modify rights for the temporary asp files directory. And now I'm left wondering why this situation requires Modify rights for the Authenticated Users group. I thought it could be because the apppool account was missing additional rights (googling for this returned some results, so I tried those), but granting the ApplicationPoolIdentity modification rights to the Windows\Temp directory and/or the application directory itself did not fix it. For now we have a workaround, but I hate that I don't know what is exactly going on here, so I was hoping any of you guys could shed some light on this. Thanx in advance!

  • .NET 2.0 Application now running slow on IIS 7.5

    - by Valien
    I recently moved (and still in testing) an application from a Windows 2003 Server (Physical box) running IIS 6.x to a Windows 2008 R2 Standard (VM) IIS 7.5 server. The application is a .NET framework 2.0 application and is running under a 2.0 App Pool. This site works great except for one thing: Takes forever to get a request back. I've been tracking it with Chrome Inspect Element and it queries the site and can take up to 45 seconds to answer. Now when it does the page(s) render instantly but it's that initial request that's killing it. I see no error logs or issues with the application or Windows Event Viewer or even IIS logs so not sure where to start looking next. Some new changes was that previously the app resided behind a Pix firewall and now is behind a larger network environment in a DMZ zone (and I believe NetScaler is also being used to manage the network). I do not have rights/abilities to look at the network itself but can contact the Data center folks to look deeper into this but I wanted to make sure it's not my application that might be causing the slowdown or IIS. In summary: .NET 2.0 application works great in IIS 6.x Application moved to an IIS 7.5 server and now slow on rendering but when it does render responds back with pages instantly. Edit for solution Found out that it was the SOAP calls that were slowing the site down. In the new datacenter my application cannot request SOAP calls and so they time out after 40-45 seconds or so.
