I am using Telerik.Web.UI.dll 2010.3.1317.35 Version. I have doubts in Rad Grid Multiple Column Header with col-span. ColumnsGroup Tag does not support for this version. so we are trying to use below 2 methods
1. Using tables TR, TD Method in Header Template in Single Template columns.
2. Server Side code methods of Grid PreRender using add new Header Item using TableHeadercell but after data bind or using column resizing then gird design will be collapse,
So, Can you Suggest me which is the correct method or any other simple method for multiple column header.

The MultiColumn Headers feature of RadGrid provides a lot of flexibility and various options for customization to achieve almost any kind of hierarchical headers spanning one or more columns or other multiheaders. You check out the feature in this live demo and found out more information on how to configure it in the relevant help topic.

Actually <ColumnGroups> tag does not support for this telerik Version. i told that in above comments...
so share me if any another methods for Multiple column header..
Unless you cannot update to the latest version which supports easy defining of MultiColumn headers as previously shown, you can use the GridTemplates column and try to mimic the same layout as shown in this help topic and demo, but note that this approach has some limitation and not all features such as sorting or reordering of columns may work correctly in this case. Additional option on programatically adding multiple header items can also be found in this forum post.
