How can you pass data to a user control?
User controls may be comprised of several server side controls. In some scenarios, developers may need to set the properties of the internal controls from the outer page. The following may be carried out:
Say the user control’s code behind file is uc.ascx.cs, open this file and then add a public method or property that the page would invoke.
Public Sub SetTheLabelText(ByVal val As String)
Label1.Text = val
Now in the page’s code behind file, declare a reference to the user control.
Protected WithEvents TheControl As TheUserControl
Next, the user control’s custom method may be invoked from within the page.
