[Solved] Incorrect documentation for RadGrid

[SUNIL]

The documentation for changing RadGrid filter menu options in JavaScript is incorrect. This documentation is at How to reduce filter options in RadGrid.

The documentation says to subscribe to the OnClientShowing event of FilterMenu, but that event never fires when the OnFilterMenuShowing event fires. The correct event should be OnClientShown of FilterMenu.

<ClientSettings>
    <ClientEvents OnFilterMenuShowing="filterMenuShowing" />
 </ClientSettings>
<FilterMenu OnClientShown="menuShown" Enabled="true" />

 

Your documentation provides the following markup, which is incorrect for the reason above.

<ClientSettings>
   <Scrolling AllowScroll="false" />
   <ClientEvents OnFilterMenuShowing="filterMenuShowing" />
</ClientSettings>
<FilterMenu OnClientShowing="MenuShowing" />

Hi Sunil,

Thank you for reporting this. We reproduced the scenario and verified the event sequence in RadGrid. When the filter menu opens, the events fire in this order:

OnFilterMenuShowing > FilterMenu.OnClientShowing > FilterMenu.OnClientShown

OnClientShowing does fire after OnFilterMenuShowing. It is the appropriate event for changing filter options before the menu is displayed. OnClientShown fires after the menu is displayed, so it is not a replacement when the goal is to modify the options before display.



We have clarified the documentation and corrected the sample handler name. I have attached a self-contained repro with an event log. It was tested with Telerik version 2026.3.812.462. If you still see different behavior, please share your Telerik version and a minimal repro.
