I need to set text property for any type controls(Ex. Textbox,Label,HyperLink..etc) from my web page dynamically. Here is my code

foreach (string id in List<IdCollection>)
{
Control ctrl = (this.Page.FindControl(id)); // Control should be HtmlGenericControl or WebControl.
ctrl.Text=???(This property is not available for Control Class)..
}

I dont need to check each and every control type for set text property as like as following codes

if(ctrl is TextBox)
{
((TextBox)ctrl).Text="test";
}

or

 if(ctrl.GetType()==typeof(TextBox))
{
 ((TextBox)ctrl).Text="test";
}

Is there any other way to set text property as simple, just like as the following code

WebControl wbCntrl=(WebControl)ctrl;
wbCntrl.Tooltip="tooltip"; //// This is possible
wbCntrl.Text="test" ??? //// But this is not possible

Thanks

If you are using C# 4.0 (VS 2010) then you could use the "dynamic" keyword:

foreach (string id in List<IdCollection>)
{
  dynamic ctrl = (this.Page.FindControl(id)); 
  ctrl.Text = "test";
}

Obviously you would get a runtime exception if you try to do this on a control that's missing the Text property.
