The GetDesignTimeHtml override generates a placeholder that includes the Value property in the placeholder, along with the control class name and the ID property.
// Generate the design-time markup.
public override string GetDesignTimeHtml()
{
// Get a reference to the control or a copy of the control.
MyHiddenField myHF = (MyHiddenField)ViewControl;
// Create a placeholder that displays the control value.
string markup = CreatePlaceHolderDesignTimeHtml(
"Value: \"" + myHF.Value.ToString() + "\"" );
return markup;
} // GetDesignTimeHtml
' Generate the design-time markup.
Public Overrides Function GetDesignTimeHtml() As String
' Get a reference to the control or a copy of the control.
Dim myHF As MyHiddenField = CType(ViewControl, MyHiddenField)
Dim markup As String = _
CreatePlaceHolderDesignTimeHtml( _
"Value: """ & myHF.Value.ToString() & """" )
Return markup
End Function ' GetDesignTimeHtml
