Hi,
I am performing the filter operation in one of the columns of type number. I have set the validation function as "Equals". If I enter some alphabet then all the existing filter conditions are lost and the grid displays all the records. Is there any possibility to avoid this? Any suggestions are highly appreciated.

Hi Das,
One option in this case would be to disallow alpha input. This can be done by using numeric/date input in the filter. They can be nested in a filter template.
Kind regards,

Thanks Yavor. This I think does not work with RADGrid Classic version. I am using RAD Grid Calssic version.

Hello Das,
Indeed, this feature is only available for the controls build for asp.net ajax.
In your case, you can attach to the ItemCommand event handler, and both validate the user input for the filtering operation, and preserve the old filter expression, so that you can restore it in case there is any invalid input, instead of returning all the records in the grid.
I hope this suggestion helps.
