Hi Ashish,

It is possible to have column widths in pixels and percent at the same time, but you should make sure that the percentage widths and pixels widths are consistent - for example, the sum of all widths should match the width of the RadGrid or the MasterTableView.

Here is a simple page, that works as expected. You should keep in mind that the browser behavior with relation to column widths is different. Internet Explorer increases all column widths by the amount of table cell paddings, while the other browsers don't do that. As a result, the column widths in IE are visually larger. The solution for this is to use small or no left/right padding for the table cells.

    
            <%@ Page Language="C#" %> 
        
            <%@ Import Namespace="System.Data" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

                int rowsNum = 10;
