Can some one please tell me the upper limit for number of data columns in a telerik datagrid ? I know if I have more than 255 then export to excel wouldn't work. Just wanted to know how many does the data grid allows if I dont plan on using export features.
As far as I know RadGrid does not have a limit for the columns that it can contain. So you should have in mind that hundreds columns in your RadGrid instance may slow the performance down.With such large amount of fields in the grid table you may consider utilizing the scrolling + static headers feature of our web grid and enable its paging feature to reduce the number of records displayed at once.

The limitation of the number of columns is int.MaxValue, but you will face performance issues with huge amount of columns.
Here is a code snippet that will allow you to test different number of columns and rows:
