Question

I’d wish to save some coding by being able to create a dynamic GetControl method. My ideas is something like this

private T GetControl<T>(ASPxGridView control, string element)
{
    var returnedElement = (T)control.FindEditFormTemplateControl(element);
    return returnedElement;
}

Which I call with

var myElement = GetControl<ASPxTextBox>(myGridView, "UserId");

But, this fails miserably:

Cannot convert type ‘System.Web.UI.Control’ to ‘T’

Any advices?

Try adding a generic constraint:

private T GetControl<T>(ASPxGridView control, string element) where T : Control
{
    var returnedElement = (T)control.FindEditFormTemplateControl(element);
    return returnedElement;
}
