In mobile and tablet device is very difficult increase and decrease the size of columns of RadGrid, exist a specified method or a workaround for resize a grid ?
Is possible increase border(left/right) of column for change it more easiest ?
The respons of my ticket in forum is that:
I am afraid we currently do not have alternative ways for resizing the Grid column. However, I advise that you share your idea officially by creating a Feature Request in the Progress® Telerik® UI for ASP.NET AJAX Feedback Portal. There the request will have the potential to become popular. Items with higher priority will be processed earlier."
