code-behind

I am using aspx. If I have HTML as follows: <div id="classMe"></div> I am hoping to dynamically add a css class through the code behind file, ie on Page_Load. Is it possible? If you want to add attributes, including the class, you need to set runat="server" on the tag. <div id="classMe" runat="server"></div> Then in the code-behind: classMe.Attributes.Add("class", "some-class") If you're not using the id for anything other than code-behind reference (since .net mangles the ids), you could use a panel control and reference it in your codebehind: <asp:panel runat="server" id="classMe"></asp

I have a rectangle in my XAML and want to change its Canvas.Left property in code behind: <UserControl x:Class="Second90.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="400" Height="300" KeyDown="txt_KeyDown"> <Canvas> <Rectangle Name="theObject" Canvas.Top="20" Canvas.Left="20" Width="10" Height="10" Fill="Gray"/> </Canvas> </UserControl> But this doesn't work: private void txt_KeyDown(object sender, KeyEventArgs e) { theObject.Canvas.Left = 50; } Does anyone know what the syntax is to do this?

I notice with the latest version of ASP.NET MVC that a View no longer defaults to having code-behind classes. How do I go about adding a code-behind class now to a View or Partial View?? Andrew Harry How to add a Code-behind page to a Partial View Seems this wasn't particularly tricky, and is quite do-able. This answer worked for a Partial ViewUserControl but the same should apply for a Normal MVC ViewPage as well Add a new Class file with the convention of <view filename & extention>.cs (i.e. view.ascx.cs ) Add using System.Web.Mvc; to the class Change the class to Inherit from
