Column Resizing in GridView

Column Resizing in GridView

The ASP.NET GridView does not support column resiziing. You must use a third party server control like:

http://demos.telerik.com/aspnet-ajax/grid/examples/client/resizing/defaultcs.aspx
http://demos.devexpress.com/aspxgridviewdemos/Columns/ColumnResizing.aspx
http://ideasparks.codeplex.com/

I recommend using coolgrid control of irespaks.
CoolGridView is a web control that extends or enhances an ASP.NET GridView control to deliver the following features:

• Display fix column headers, footer and pager
• Supports scrollable content
• User-resizeable column widths (New!)
• Maintains scroll position and column widths after a postback or callback (New!)

You can also make a resizable GridView using jQuery colResizable-1.3.min.js.You can download it from http://quocity.com/colresizable/

Step 1: Your .aspx page like:
