Control.Find<T>(string id) Extension Method

For my current project, I am constantly using FindControl to dynamically locate a child control within a parent control. Instead of constantly typing this:

   1: DropDownList dropDownList = employeeListView.FindControl("regionDropDownList") as DropDownList;

I created an extention method to prettify my code:

   1: public static class ControlExtensions
   2: {
   3:     public static T Find<T>(this Control control, string id) where T : Control
   4:     {
   5:         return (T) control.FindControl(id);
   6:     }
   7: }

So now I can type this:

   1: employeeListView.Find<DropDownList>("regionDropDownList");

Fixing the Display of Variable Width Select Lists in IE7

I recently helped a client with an ASP.NET website that targeted the IE7 browser. We weren’t doing anything specific that required IE7, but we knew that 99% of the users would be using IE7 as this was the standard installation for the internal users who would be given access to the system.

Several of the pages had select lists in the header of tables that would act as column filters. Unfortunately, IE7 has an incredibly annoying method of rendering select lists. It will shrink the input so that it is contained with its parent element, but when you click the pull-down to expand the selection list, the list does not expand to the width of the select list item. In our case, with narrow columns this resulted in some select lists where the user could only see the first few letters of each option, which is obviously useless.
