  • Can't find controls in FormView.InsertItemTemplate even on DataBound event

    - by abatishchev
    I have FormView in my page markup: <asp:FormView ruanat="server" ID="FormView1" OnDataBound="FormView1_DataBound" DataSourceID="SqlDataSource1"> <InsertItemTemplate> <uc:UserControl1 runat="server" ID="ucUserControl1" /> </InsertItemTemplate> </asp:FormView> <asp:SqlDataSource runat="server" ID="SqlDataSource1" SelectCommand="EXEC someSP" /> It's code-behind: protected void FormView1_DataBound (object sender, EventArgs e) { var c1 = ((FormView)sender).FindControl("ucUserControl1"); // returns null var c2 = FormView1.FindControl("ucUserControl1"); // also returns null } In theory, I'm able to find control on FormView after it being data bound. But I'm not. Why?

  • ASP.NET 2.0: Specifying an instance of an object for an ObjectDataSource

    - by Austin Salonen
    I'm using an ObjectDataSource to bind data to a GridView; it works fine except that it always creates a new object to use as a data source. I can do all the setup just fine but I cannot use an instance of an existing object to specify as the "data source" for it. Is it possible to do this? If so, how? If it's not possible, why? EDIT: Here's the gist of what's going on (object types changed): On the first page you are editting the attributes for a dog. One of the attributes is "has puppies" and if it's true, the next page you specify the names of those puppies. What's happening in my case is that those puppies are not getting linked to the original dog but to a "new" dog. (The implication that my problem is a "female dog" was coincidental. ;-) )

  • ASP.NET MVC Model Binding

    - by Noel
    If i have a Controller Action that may recieve both HTTP GET and HTTP POST from a number of different sources with each source sending different data e.g. Source1 performs a form POST with two form items Item1 and Item2 Source2 performs a GET where the data is contained in the query string (?ItemX=2&ItemY=3) Is it possible to have a controller action that will cater for all these cases and perform binding automatically e.g. public ActionResult Test(Dictionary data) { // Do work ... return View(); } Is this possible with a custom binder or some other way? Dont want to work directly with HttpContext.Request if possible

  • Can't get NUnit to work in Visual Web Develper 2010 express.

    - by UkraineTrain
    First off I was wondering whether it's possible to implement a functionality with Nunit where each time a project is created in Visual Web Developer 2010 I get a dialog asking whether I want to create a unit test project for current application like I saw it happen in the older versions of Visual Web Developer. I've tried just about everything to get NUnit 2.5.5 to work in Visual Web Developer 2010. For example, in nunit.exe.config I added under configuration <startup> <requiredRuntime version="v4.0.30319" /> </startup> and under runtime: <loadFromRemoteSources enabled="true" /> I then tried to launch nunit-console.exe in order to specify in the command line the option /framework=net-4.0, but the console would appear and instantly disappear. It didn't help when I tried running it as an administrator. I've also tried using Nunit as an external tool inside the Visual Web Developer by creating a toolbar as described in the following link: http://www.marthijnvandenheuvel.com/2010/06/09/using-nunit-in-visual-studio-2010/. It shows up as an icon in the toolbar. I ran my project called ToyStore and then clicked Nunit icon in order to launch it and it gave me a "System.IO.FileNotFoundException:Assembly not found:ToyStore.dll". So, needless to say, I'm pretty lost and don't know what to do and would greatly appreciate any help in getting Nunit to work.

  • ASP .NET MVC partial views and routing

    - by Johnny
    Hi, I have an MVC view that contains a number of partial views. These partial views are populated using partial requests so the controller for the view itself doesn't pass any data to them. Is it possible to reload the data in one of those partial views if an action was triggered in another? For example, one partial view has a jqGrid and I want to refresh the data in another partial view when a user selects a new row in this grid. Is there a code example for this scenario (in C#) that I can look at to see what am I doing wrong? I am using ajax calls to trigger a new request but non of the partial views are refreshed so I am not sure if the issue is with the routing, the controller, or if this even possible at all! Thanks!

  • Where does the ObjectDataSource cache data?

    - by Jeremy
    I'm considering using an ObjectDataSource as an intermediate between my page controls and my data access layer & object model. Traditionally I have manually created the object and populate it via a series of findcontrol statements when I need to insert/update data in the database. I'm hoping that I can use the ObjectDataSource to marshal data between my object and my controls, eliminating that manual code, as long as the ObjectDataSource doesn't come with a lot of overhead. I noticed the EnableCaching property, where does the caching occure? is it in view state?

  • How to dispose data context after usage

    - by Erwin
    Hi fellow programmer I have a member class that returned IQueryable from a data context public static IQueryable<TB_Country> GetCountriesQ() { IQueryable<TB_Country> country; Bn_Master_DataDataContext db = new Bn_Master_DataDataContext(); country = db.TB_Countries .OrderBy(o => o.CountryName); return country; } As you can see I don't delete the data context after usage. Because if I delete it, the code that call this method cannot use the IQueryable (perhaps because of deferred execution?). How to force immediate execution to this method? So I can dispose the data context.. Thank you :D

  • Visual Studio Web Application edit source while running like in Tomcat\Eclipse\Java

    - by Bryan Migliorisi
    In an ASP.NET Web Site project, I've always been able to make changes to the underlying C# code and simply refresh the page in the browser and my changes would be there instantly. I can do the same thing when working with Java and Eclipse - edit my Java source and refresh the page and my changes are there. I cannot do this in ASP.NET MVC though and it is a real downer - I have to stop the running process and make my changes, and then restart debugging. This is a huge waste of time. Am I doing it wrong? What is the best approach to ASP.NET MVC development?

  • Web Services: Secure? Asp.net

    - by Jacques
    Hey there, Something I can't wrap my head around is how secure web services are. For example we're writing a desktop application that will interact with data on one of our websites as well as local data. This data is sensitive though and the last thing we want is anybody calling the web services. I've not yet found anything that says web services has some kind of authentication methods and the only security I've seen people talk about is using certificates to encrypt the message. I'm no guru on this and would appreciate anyone's input and perhaps a link to somewhere that will explain this in simple terms. Thanks Jacques

  • Best practice? iphone: sync data

    - by Andy Jacobs
    So i'm working on a project where there is data visualization. My ultimate goal is that i have a set of data shipped with the download of the iphone app. But i want it connected to a backend, that if the iphone has a connection with the internet. it can sync the changes from the backend. The syncing is no problem or the connection between the backend & the iphone. But what should i use as data storage on my iphone? what is the best way. my data is purely text and doesn't have to be secure. But it's main feature should be updating certain parts of data ( adding and deleting are not so important ) so what is the easiest (read: least time consuming development ) or the best way? sqlite? plist? ..?

  • How to best show progress info when using ADO.NET?

    - by Yadyn
    I want to show the user detailed progress information when performing potentially lengthy database operations. Specifically, when inserting/updating data that may be on the order of hundreds of KB or MB. Currently, I'm using in-memory DataTables and DataRows which are then synced with the database via TableAdapter.Update calls. This works fine and dandy, but the single call leaves little opportunity to glean any kind of progress info to show to the user. I have no idea how much data is passing through the network to the remote DB or its progress. Basically, all I know is when Update returns and it is assumed complete (barring any errors or exceptions). But this means all I can show is 0% and then a pause and then 100%. I can count the number of rows, even going so far to cound how many are actually Modified or Added, and I could even maybe calculate per DataRow its estimated size based on the datatype of each column, using sizeof for value types like int and checking length for things like strings or byte arrays. With that, I could probably determine, before updating, an estimated total transfer size, but I'm still stuck without any progress info once Update is called on the TableAdapter. Am I stuck just using an indeterminate progress bar or mouse waiting cursor? Would I need to radically change our data access layer to be able to hook into this kind of information? Even if I can't get it down to the precise KB transferred (like a web browser file download progress bar), could I at least know when each DataRow/DataTable finishes or something? How do you best show this kind of progress info using ADO.NET?

  • Where should I store my application data?

    - by joebeazelman
    I have an application that needs to store data. Currently, I am using the built-in Application Settings to do it, but it only gives me two choices: application and user scopes. Ideally, I want a "local" scope that allows the application to run under another user and still find its data rather than recreate it for that user. The application scope can do this, but it's read only. The application data will be changed by the user. It's OK if only the administrator is allowed to make changes to the data. As you probably can guess, I have an administration tool that allows the user to change the data and windows service runner that reads the data and does something with it. It would be great if the windows service runner access the data created by the administration tool.

  • SQL Server Compact 'Data Directory' macro in Connection String - more info needed

    - by codeulike
    So, as described on this msdn page, when you define a Connection String for SQL Server Compact 3.5, you can use the "Data Directory" macro, like this: quote from this msdn page: Data Directory Support SQL Server Compact 3.5 now supports the Data Directory macro. This means that if you add the string |DataDirectory| (enclosed in pipe symbols) to a file path, it will resolve to the path of the database. For example, consider the connection string: "Data Source= c:\program files\MyApp\Mydb.sdf" When using Data Directory, you can instead use the following connection string: "Data Source = |DataDirectory|\Mydb.sdf" For more information, see How to: Deploy a SQL Server Compact 3.5 Database with an Application. However, the 'for more information' link on msdn doesn't actually give any more information. So my question is: How does the |Data Directory| macro translate at run time? For WinForm apps, it seems to just give the location of the executable. Or is it more complicated than that?

  • XML Validation in ASP.NET MVC during load

    - by Jamie Nordmeyer
    I'm writing an ASP.NET MVC 2 application where one of the backing stores I plan to support is XML. I have a POCO that represents the settings for the site, along with an XML file to contain these settings. My question is what is the best way to validate this data as it is read from disk in to the POCO? I know I can use an XSD, or maybe use the Data Annotations library to mark up the POCO, and use reflection to validate the data, but is there another way, perhaps in .NET 3.5 or MVC to do this? I've spent some time Googling this issue, and want to be sure I'm doing it in the best manner. Thanks in advance!

  • Update panel in Tab Container

    - by Sam_Cogan
    I have a tab container with 5 tabs, each tab contains an update panel. When the user initially opens the form, they can only see the first Tab, the others are set to visible=false. Once they have completed the first form, the hit save which sends a partial postback to save the data to the DB. Once that is saved, I then want to set all the other tabs to visible, however this does not work at the moment, I am assuming because the tab container is not contained in an update panel. How can I get this to work, do I need to put the tab container in it's own update panel, which will obviously then contain all the other update panels, or should I not use an update panel in the first tab and do a full page postback?

  • Explaining persistent data structures in simple terms

    - by Jason Baker
    I'm working on a library for Python that implements some persistent data structures (mainly as a learning exercise). However, I'm beginning to learn that explaining persistent data structures to people unfamiliar with them can be difficult. Can someone help me think of an easy (or at least the least complicated) way to describe persistent data structures to them? I've had a couple of people tell me that the documentation that I have is somewhat confusing. (And before anyone asks, no I don't mean persistent data structures as in persisted to the file system. Google persistent data structures if you're unclear on this.)

Can someone tell me how to resolve this issue?

  • What VS Projecttype for Model and Database?

    - by Tim
    Hello folks, i've just started a new asp.net project which could increase fastly(a small erp-system for our company). So i thought it would be a good idea to split at least the model from the view/controller(the asp.net project). Because it could be that i need to access some classes and the database from a windows app in future, i dicided to put the Model into its own Project. What Visual Studio 2005 Professional Projecttype is most suitable for this requirement and why? SqlServerProject (DB is MS Sql Server 2005 EP) Class Library Web Service Application Database project no separate Project/other(keep in mind VS 2005 has no ASP.NET MVC-Project) Thanks

  • Data mining logs to locate a bug

    - by gooli
    I'm working on a data distribution application which receives data from a source and distributes that data to multiple target application. After successfully distributing several messages each second for 8 days, it missed a single message and did not deliver it properly to the clients. As I was looking at the logs I tried to find something there that was special for the time the miss happend - either in the data, its rate or some other condition but couldn't find anything. Is there any data mining technique I can use to identify how that specific event differs from other events?

  • IDENTITY_INSERT is set to off error

    - by kingrichard2005
    I have a MVC web application with a table in the model that I would like to add to. I have the primary key set along with the other data fields, but every time I try to add to the table, I get the following error: "Cannot insert explicit value for identity column in table 'TABLE_NAME' when IDENTITY_INSERT is set to OFF." I'm not sure why this problem is coming up, I have the primary key set as the identity and it is also set to auto increment in the Visual Studio table designer. Is there any way I can adjust the IDENTITY_INSERT parameter in the table designer in Visual Studio?? Or is there some other issue that might be causing this.

  • Why doesn't a LinkButton work with a table as it's content?

    - by Telos
    Using ASP.NET 3.5, you can create a LinkButton then define content inside of it. It works fine if I have div tags or any kind of text or anything, but if I use a table the click doesn't actually post back for some reason. This should take you to google (you'll get an error there but it should still go) for instance: <asp:LinkButton ID="lbTest" PostBackUrl="http://www.google.com" runat="server"> <table> <tr> <td>Test</td> <td>col2</td> <td>col3</td> </tr> </table> </asp:LinkButton> I could work around it by building a "table" with divs I guess, but I hate formatting with divs.

  • Linq ChangeConflictException (ASP.NET MVC) - occurs when submitting DataContext changes

    System.Data.Linq.ChangeConflictException: 2 of X updates failed. at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode) at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode) at PROJECT.Controllers.HomeController.ClickProc(Int32 id, String code, String n) This is what I get very often. This action is done thousands of times a day, and I get this exception about once every 5 seconds. From what I understand it happens when something changes in the database in the period between creating DataContext and updating it. Am I right? What's the problem here and how can I fix it?
