  • Does anyone know of Telerik deals?

    - by Seagull
    This may be the wrong forum to ask... But since there are so many Telerik fans here, I was wondering if anyone is aware of discount coupons or upcoming deals the company may have? I ask because VS2010 is coming, and I suspect they may therefore have deals released at a similar timeframe. I am a bit 'cheap' because I am just starting a one-man business...

  • Loop to LINQ Conversion -

    - by Pino
    Ok I have the following, set-up and working great. These lines of code should do a conversion from DAL Entity (Subsonic) to a ViewModel. IList<ProductOptionModel> OptionsRetData = new List<ProductOptionModel>(); foreach (var CurProductOption in this.ProductOptions) { OptionsRetData.Add(CurProductOption.ToDataModel()); } returnData.Options = OptionsRetData.AsEnumerable(); I'd like to convert this to a LINQ single line statment and came up with the following. returnData.Options = this.ProductOptions.Select(o => o.ToDataModel()); and am recieving the following error. Server Error in '/' Application. Sequence contains no matching element So why does the first statment work but not the LINQ and, what steps can I take to resolve it.

  • Help Repainting a Line

    - by serhio
    I am doing a custom control (inherited from VisualBasic.PowerPacks.LineShape), that should be painted like as standard one, but also having a Icon displayed near it. So, I just overrided OnPaint like this: protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { e.Graphics.DrawIcon(myIcon, StartPoint.X, StartPoint.Y); base.OnPaint(e); } Now, everything is OK, but when my control moves, the icon still remains drawn on the ancient place. Is there a way to paint it properly? The sample code for tests using Microsoft.VisualBasic.PowerPacks; using System.Windows.Forms; using System.Drawing; namespace LineShapeTest { /// /// Test Form /// public class Form1 : Form { IconLineShape myLine = new IconLineShape(); ShapeContainer shapeContainer1 = new ShapeContainer(); Panel panel1 = new Panel(); public Form1() { this.panel1.Dock = DockStyle.Fill; // load your back image here this.panel1.BackgroundImage = global::WindowsApplication22.Properties.Resources._13820t; this.panel1.Controls.Add(shapeContainer1); this.myLine.StartPoint = new Point(20, 30); this.myLine.EndPoint = new Point(80, 120); this.myLine.Parent = this.shapeContainer1; MouseEventHandler panelMouseMove = new MouseEventHandler(this.panel1_MouseMove); this.panel1.MouseMove += panelMouseMove; this.shapeContainer1.MouseMove += panelMouseMove; this.Controls.Add(panel1); } private void panel1_MouseMove(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { myLine.StartPoint = e.Location; } } } /// /// Test LineShape /// public class IconLineShape : LineShape { Icon myIcon = SystemIcons.Exclamation; protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { e.Graphics.DrawIcon(myIcon, StartPoint.X, StartPoint.Y); base.OnPaint(e); } } } Nota Bene, for the lineShape: Parent = ShapeContainer Parent.Parent = Panel Update 1 TRACES In this variant of OnPaint, we have traces: protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { Graphics g = Parent.Parent.CreateGraphics(); g.DrawIcon(myIcon, StartPoint.X, StartPoint.Y); base.OnPaint(e); } Update 2 BLINKS In this variant of OnPaint, we have a blinking image: protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { Parent.Parent.Invalidate(this.Region, true); Graphics g = Parent.Parent.CreateGraphics(); g.DrawIcon(myIcon, StartPoint.X, StartPoint.Y); base.OnPaint(e); } Update 3: External Invalidation This variant works well, but... from exterior of IconLineShape class: private void panel1_MouseMove(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { Region r = myLine.Region; myLine.StartPoint = e.Location; panel1.Invalidate(r); } } /// /// Test LineShape /// public class IconLineShape : LineShape { Icon myIcon = SystemIcons.Exclamation; Graphics parentGraphics; protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { parentGraphics.DrawIcon(myIcon, StartPoint.X, StartPoint.Y); base.OnPaint(e); } protected override void OnParentChanged(System.EventArgs e) { // Parent is a ShapeContainer // Parent.Parent is a Panel parentGraphics = Parent.Parent.CreateGraphics(); base.OnParentChanged(e); } } Even this resolves the problem of the test example, I need this control to be done inside the control, because I can't force the external "clients" of this control do not forget to save the old region and invalidate the parent each time changing a location...

  • Use fileupload as template field in a details view

    - by MyHeadHurts
    I have an admin page where a user will select a document path and add that path to a certain column of a database. I am using a fileupload on the page where they can find the document and copy the path and then paste it into the details view. However, I want to skip this step and I want them to select a document and automatically make the path show up in the details view. <asp:FileUpload ID="FileUpload1" runat="server" Visible="False" Width="384px" /><br /> <br /> <div> <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <center> <asp:DetailsView ID="DetailsView1" runat="server" AllowPaging="True" AutoGenerateRows="False" DataKeyNames="ID" DataSourceID="SqlDataSource1" Height="128px" Width="544px" Visible="False" OnModeChanged="Button2_Click" CellPadding="4" ForeColor="#333333" GridLines="None" > <Fields> <asp:BoundField DataField="Order" HeaderText="Order" SortExpression="Order" /> <asp:BoundField DataField="Department" HeaderText="Department" SortExpression="Department"/> <asp:BoundField DataField="DOC_Type" HeaderText="DOC_Type" SortExpression="DOC_Type" /> <asp:BoundField DataField="Title" HeaderText="Title" SortExpression="Title" /> <asp:BoundField DataField="Revision" HeaderText="Revision" SortExpression="Revision" /> <asp:BoundField DataField="DOC" HeaderText="DOC" SortExpression="DOC" /> <asp:BoundField DataField="Active" HeaderText="Active" SortExpression="Active" /> <asp:BoundField DataField="Rev_Date" HeaderText="Rev_Date" SortExpression="Rev_Date" /> <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True" SortExpression="ID" Visible="False" /> <asp:CommandField ShowInsertButton="True" /> </Fields> <FooterStyle BackColor="#5D7B9D" BorderStyle="None" Font-Bold="True" ForeColor="White" /> <CommandRowStyle BackColor="#E2DED6" BorderStyle="None" Font-Bold="True" /> <RowStyle BackColor="#F7F6F3" BorderStyle="None" ForeColor="#333333" /> <FieldHeaderStyle BackColor="#E9ECF1" BorderStyle="None" Font-Bold="True" /> <EmptyDataRowStyle BorderStyle="None" /> <PagerStyle BackColor="#284775" BorderStyle="None" ForeColor="White" HorizontalAlign="Center" /> <HeaderStyle BackColor="#5D7B9D" BorderStyle="None" Font-Bold="True" ForeColor="White" /> <InsertRowStyle BorderStyle="None" /> <EditRowStyle BackColor="#999999" BorderStyle="None" /> <AlternatingRowStyle BackColor="White" BorderStyle="None" ForeColor="#284775" /> </asp:DetailsView> &nbsp; <br /> I need to get the fileupload1 into the DOC contenttemplate area so instead of showing an empty textbox it will show just a textbox it will show the fileupload

  • How to Create a Generic Method and Create Instance of The Type

    - by DaveDev
    Hi Guys I want to create a helper method that I can imagine has a signature similar to this: public static MyHtmlTag GenerateTag<T>(this HtmlHelper htmlHelper, object obj) { // how do I create an instance of MyAnchor? // this returns MyAnchor, which has a MyHtmlTag base } When I invoke the method, I want to specify a type of MyHtmlTag, such as MyAnchor, e.g.: <%= Html.GenerateTag<MyAnchor>(obj) %> or <%= Html.GenerateTag<MySpan>(obj) %> Can someone show me how to create this method? Also, what's involved in creating an instance of the type I specified? Activator.CreateInstance()? Thanks Dave

  • Cyclic References and WCF

    - by Kunal
    I have generated my POCO entities using POCO Generator, I have more than 150+ tables in my database. I am sharing POCO entities all across the application layers including the client. I have disabled both LazyLoading and ProxyCreation in my context.I am using WCF on top of my data access and business layer. Now, When I return a poco entity to my client, I get an error saying "Underlying connection was closed" I enabled WCF tracing and found the exact error : Contains cycles and cannot be serialized if reference tracking is disabled. I Looked at MSDN and found solutions like setting IsReference=true in the DataContract method atttribute but I am not decorating my POCO classes with DataContracts and I assume there is no need of it as well. I won't be calling that as a POCO if I decorate a class with DataContract attribute Then, I found solutions like applying custom attribute [CyclicReferenceAware] over my ServiceContracts.That did work but I wanted to throw this question to community to see how other people managed this and also why Microsoft didn't give built in support for figuring out cyclic references while serializing POCO classes

  • Stack trace in website project, when debug = false

    - by chandmk
    We have a website project. We are logging unhanded exceptions via a appdomain level exception handler. When we set debug= true in web.config, the exception log is showing the offending line numbers in the stack trace. But when we set debug = false, in web.config, log is not displaying the line numbers. We are not in a position to convert the website project in to webapplication project type at this time. Its legacy application and almost all the code is in aspx pages. We also need to leave the project in 'updatable' mode. i.e. We can't user pre-compile option. We are generating pdb files. Is there anyway to tell this kind of website projects to generate the pdb files, and show the line numbers in the stack trace?

  • To Reference A Generic Method With A Lambda Expression

    - by SDReyes
    It is possible to reference a generic method using a Lambda Expression Object? For example, having: TheObject: public abstract class LambdaExpression : Expression TheMethod (an extension method of LINQ): public static TSource Last<TSource>( this IEnumerable<TSource> source ) I'm trying to create an instance of TheObject, that references to TheMethod. How do you do such thing?

  • Localization with separate Language folders within Views

    - by Adrian
    I'm trying to have specific folders for each language in Views. (I know this isn't the best way of doing it but it has to be this way for now) e.g. /Views/EN/User/Edit.aspx /Views/US/User/Edit.aspx These would both use the same controller and model but have different Views for each language. In my Global.asax.cs I have routes.MapRoute( "Default", // Route name "{language}/{controller}/{action}/{id}", // URL with parameters new { language = "en", controller = "Logon", action = "Index", id = UrlParameter.Optional }, // Parameter defaults new { language = @"en|us" } // validation ); This works ok but always points to the same View. If I put the path to the Lanagugage folder it works return View("~/Views/EN/User/Edit.aspx"); but clearly this isn't a very nice way to do it. Is there anyway to get MVC to look in the correct language folder? Thanks and again I know this isn't the best way of doing Localization but I can't use resource files.

  • Error Messaged and Error Code design

    - by Ved
    We are designing set of web services which will return XML string in response. These are RESTFul services so I will have to send exception inside element. I am planing to design set of Error code which can help me determine where level occured just by looking at the code. For Example 1000 - Application Level 2000 - DB level 3000 - Network level so if I have error message then I can know right away that this was an application level error and it came from 1st business module. I am not very experience in this so I would love to here your thoughts and criticism. Thanks

  • Visual Studio confused by server code inside javascript

    - by Felix
    I ran into an annoying problem: the following code gives a warning in Visual Studio. <script type="text/javascript"> var x = <%: ViewData["param"] %>; </script> The warning is "Expected expression". Visual Studion gets confused, and all the javascript code after that is giving tons of warnings. Granted, it's all warnings, and it works perfectly fine in runtime - but it is very easy to miss real warnings among dozen of false positives. It was working the same way in VS2008, and it wasn't fixed in VS2010. Does anybody know if there is a workaround, or a patch?

  • How do I assert that two arbitrary type objects are equivalent, without requiring them to be equal?

    - by Tomas Lycken
    To accomplish this (but failing to do so) I'm reflecting over properties of an expected and actual object and making sure their values are equal. This works as expected as long as their properties are single objects, i.e. not lists, arrays, IEnumerable... If the property is a list of some sort, the test fails (on the Assert.AreEqual(...) inside the for loop). public void WithCorrectModel<TModelType>(TModelType expected, string error = "") where TModelType : class { var actual = _result.ViewData.Model as TModelType; Assert.IsNotNull(actual, error); Assert.IsInstanceOfType(actual, typeof(TModelType), error); foreach (var prop in typeof(TModelType).GetProperties()) { Assert.AreEqual(prop.GetValue(expected, null), prop.GetValue(actual, null), error); } } If dealing with a list property, I would get the expected results if I instead used CollectionAssert.AreEquivalent(...) but that requires me to cast to ICollection, which in turn requries me to know the type listed, which I don't (want to). It also requires me to know which properties are list types, which I don't know how to. So, how should I assert that two objects of an arbitrary type are equivalent? Note: I specifically don't want to require them to be equal, since one comes from my tested object and one is built in my test class to have something to compare with.

  • What are windows IPC methods

    - by Quandary
    Question: I have a dll that I can load in another program. Now the dll has access to all data/functions in the other program. Which technology can I use that now an external program can send data/commands to that dll, to steer the other program, or get data from it ? I mean, in the past that meant DDE, I think that was back in Windows 3.11/95 times. What can I use today? Which one is easiest ? Which one is fastest?

  • Set a dropdown option to selected based on get variable in url in Razor MVC

    - by Mason240
    I have a dropdown menu in a GET form. When the user hits submit, they are directed to the same page and shown the form again. I would like to have the dropdown option the user displayed in the last page already selected. So for example: @Html.DropDownList("Type", null, "Type", new { @class = "sbox-input" } ) website.com/Search?Type="Beef" <select name="Type"> <option value="Fish" >Fish</option> <option value="Chicken" >Chicken</option> <option value="Beef" selected="selected">Beef</option> </select> A jQuery solution would work just as well.

  • MVC 3 Client Validation works intermittently

    - by Gutek
    I have MVC 3 version, System.Web.Mvc product version is: 3.0.20105.0 modified on 5th of Jan 2011 - i think that's the latest. I’ve notice that client validation is not working as it suppose in the application that we are creating, so I’ve made a quick test. I’ve created basic MVC 3 Application using Internet Application template. I’ve added Test Controller: using System.Web.Mvc; using MvcApplication3.Models; namespace MvcApplication3.Controllers { public class TestController : Controller { public ActionResult Index() { return View(); } public ActionResult Create() { Sample model = new Sample(); return View(model); } [HttpPost] public ActionResult Create(Sample model) { if(!ModelState.IsValid) { return View(); } return RedirectToAction("Display"); } public ActionResult Display() { Sample model = new Sample(); model.Age = 10; model.CardNumber = "1324234"; model.Email = "[email protected]"; model.Title = "hahah"; return View(model); } } } Model: using System.ComponentModel.DataAnnotations; namespace MvcApplication3.Models { public class Sample { [Required] public string Title { get; set; } [Required] public string Email { get; set; } [Required] [Range(4, 120, ErrorMessage = "Oi! Common!")] public short Age { get; set; } [Required] public string CardNumber { get; set; } } } And 3 views: Create: @model MvcApplication3.Models.Sample @{ ViewBag.Title = "Create"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Create</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @*@{ Html.EnableClientValidation(); }*@ @using (Html.BeginForm()) { @Html.ValidationSummary(false) <fieldset> <legend>Sample</legend> <div class="editor-label"> @Html.LabelFor(model => model.Title) </div> <div class="editor-field"> @Html.EditorFor(model => model.Title) @Html.ValidationMessageFor(model => model.Title) </div> <div class="editor-label"> @Html.LabelFor(model => model.Email) </div> <div class="editor-field"> @Html.EditorFor(model => model.Email) @Html.ValidationMessageFor(model => model.Email) </div> <div class="editor-label"> @Html.LabelFor(model => model.Age) </div> <div class="editor-field"> @Html.EditorFor(model => model.Age) @Html.ValidationMessageFor(model => model.Age) </div> <div class="editor-label"> @Html.LabelFor(model => model.CardNumber) </div> <div class="editor-field"> @Html.EditorFor(model => model.CardNumber) @Html.ValidationMessageFor(model => model.CardNumber) </div> <p> <input type="submit" value="Create" /> </p> </fieldset> @*<fieldset> @Html.EditorForModel() <p> <input type="submit" value="Create" /> </p> </fieldset> *@ } <div> @Html.ActionLink("Back to List", "Index") </div> Display: @model MvcApplication3.Models.Sample @{ ViewBag.Title = "Display"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Display</h2> <fieldset> <legend>Sample</legend> <div class="display-label">Title</div> <div class="display-field">@Model.Title</div> <div class="display-label">Email</div> <div class="display-field">@Model.Email</div> <div class="display-label">Age</div> <div class="display-field">@Model.Age</div> <div class="display-label">CardNumber</div> <div class="display-field">@Model.CardNumber</div> </fieldset> <p> @Html.ActionLink("Back to List", "Index") </p> Index: @{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Index</h2> <p> @Html.ActionLink("Create", "Create") </p> <p> @Html.ActionLink("Display", "Display") </p> Everything is default here – Create Controller, AddView from controller action with model specified with proper scaffold template and using provided layout in sample application. When I will go to /Test/Create client validation in most cases works only for Title and Age fields, after clicking Create it works for all fields (create does not goes to server). However in some cases (after a build) Title validation is not working and Email is, or CardNumber or Title and CardNumber but Email is not. But never all validation is working before clicking Create. I’ve tried creating form with Html.EditorForModel as well as enforce client validation just before BeginForm: @{ Html.EnableClientValidation(); } I’m providing a source code for this sample on dropbox – as maybe our dev env is broken :/ I’ve done tests on IE 8 and Chrome 10 beta. Just in case, in web config validation scripts are enabled: <appSettings> <add key="ClientValidationEnabled" value="true"/> <add key="UnobtrusiveJavaScriptEnabled" value="true"/> </appSettings> So my questions are Is there a way to ensure that Client validation will work as it supposed to work and not intermittently? Is this a desired behavior and I'm missing something in configuration/implementation?

  • Casting Between Data Types in C#

  • Modify post data with a custom MVC extension?

    - by Jaxidian
    So I'm looking into writing some custom MVC extensions and the first one I'm attempting to tackle is a FormattedTextBox to handle things such as currency, dates, and times. I have the rendering of it working perfectly, formatting it, working with strong types and everything all golden. However, the problem I'm now running into is cleaning up the formatted stuff when the page posts the data back. Take for example, a currency format. Let's use USD for these examples. When an object has a property as a decimal, the value would be 79.95. Your edit view would be something like: <%= Html.FormattedTextBox(model => Model.Person.HourlyWage, "{0:C}") %> This is all well and good for the GET request, but upon POST, the value is going to be $79.95, which when you assign to that decimal, gets unhappy very quickly and ends up shoving a 0 in there. So my question is, how do I get code working somewhere to work with that value before the MVC Framework goes and starts shoving it back into my ViewModel? I'd much rather this be done server-side than client-side. Thanks!!

  • Retrieving the type of a Collection

    - by nevets1219
    So I have something like the following in Java: private List<SomeType>variable; // ....variable is instantiated as so ... variable = new ArrayList<SomeType>(); // there's also a getter public List<SomeType> getVariable() { /* code */ } What I would like to be able to do is figure out that variable is a collection of SomeType programmatically. I read here that I can determine that from the method getVariable() but is there any way to tell directly from variable? I have been able to retrieve SomeType from the getter method based on the information in the link. I have also been successful in retrieving all the fields of the surrounding class via SurroundingClass.getClass().getDeclaredFields() but this doesn't tell me that it is List<SomeType>.

  • Java generic Comparable where subclasses can't compare to eachother

    - by dege
    public abstract class MyAbs implements Comparable<MyAbs> This would work but then I would be able to compare class A and B with each other if they both extend MyAbs. What I want to accomplish however is the exact opposite. So does anyone know a way to get the generic type to be the own class? Seemed like such a simple thing at first... Edit: To explain it a little further with an example. Say you have an abstract class animals, then you extend it with Dogs and ants. I wouldn't want to compare ants with Dogs but I however would want to compare one dog with another. The dog might have a variable saying what color it is and that is what I want to use in the compareTo method. However when it comes to ants I would rather want to compare ant's size than their color. Hope that clears it up. Could possibly be a design flaw however.
