Hi all,

1) I have implemented Rad ajax panel(progress bar) for Rad grid on click of Link button if it is going to  any exception the page is getting hanged due to Rad ajax panel  until any event is fired how can we handle when we got any exception

2)the Between option for Filtering is Showing Wrong data for dates when we use Telerik grid bound column i also used Datatype as system.datatime if we use Telerik Datetime it is not showing Between option.

Hello yeswanth,

1) I would suggest you not to nest the RadAjaxPanel and the ASP:UpdatePanel controls. You should use either RadAjaxPanel or ASP:UpdatePanel in order to ajaxify particular page content but both. Therefore, please try removing the ASP:UpdatePanel and see if the loading image is displayed properly now.

2) Indeed, the default filter functions for the GridDateTimeColumn do not include Between/NotBetween as this would require one more RadDatePicker control in the column filter.
Regarding the case when you are using GridBoundColumn with DataType of System.DateTime, try setting the EnableLinqExpressions property of the grid to false and see if the column is filtered properly.
Additionally, in order to implement the Between filter for date columns, you could try the approach illustrated in this demo.

I hope this helps.

Best wishes,
Iana
