I would suggest that you reference the RadGrid documentation page which explains how to create template columns dynamically.

http://www.telerik.com/help/aspnet-ajax/grdprogrammaticcreation.html

This is covered in the last section entitled 'Creating template columns programmatically'.

You can get the name that the user assigns for the column and then use it to replace the hardcoded column name in the following snippet:

string templateColumnName = "ContactName";
GridTemplateColumn templateColumn = new GridTemplateColumn();
templateColumn.ItemTemplate = new MyTemplate(templateColumnName);

Also, it's pretty easy to combine regular expression with a RadNumericTextBox that you add to your ItemTemplate to additionally validate user input while typing. You can reference this forum thread for insights.

Hope this helps!
