SYMPTOMS

When you create a Web User control and drag it to an .aspx page, Visual Studio .NET does not automatically generate a code-behind declaration for the Web User control.

To resolve this problem, manually enter the declaration for the Web User control in the code-behind file. The following two code examples show a Web Form (WebForm1) with an embedded Button control. You can add the declaration for the Web User control in the same place that Visual Studio .NET adds the declaration for the Button control.

Microsoft Visual C# .NET example

public class WebForm1 : System.Web.UI.Page
{
	protected System.Web.UI.WebControls.Button Button1;
protected WebUserControl1 ctlMyControl;

Microsoft Visual Basic .NET example

Public Class WebForm1
	Inherits System.Web.UI.Page
	Protected WithEvents Button1 As System.Web.UI.WebControls.Button
