OnClientBeforeClose Event Only Fires On The First Window That Is Opened

[Tracy]

Hi,

 I have a RadWindowManager on a page where I have a function assigned to the OnClientBeforeClose event.

<telerik:RadWindowManager ID="rwmManager"  runat="server"  DestroyOnClose="true"   ReloadOnShow="true"   CenterIfModal="true"  OnClientClose="RefreshGrid" OnClientBeforeClose="ChangeAlert"  />

 

The problem I am having is that the OnClientBeforeClose event only fires the first time I open the window.  If I close the window and then re-open and then subsequently close the window, the OnClientBeforeClose event doesn't fire.

 

If I change the DestroyOnClose = "false" then the event will fire every time, but the previous window I opened gets cached and flashes on the screen before the new window is opened.

How can I make this work without setting the DestroyOnClose to false.

Thank You

Tracy

Hello Tracy,

This probably stems from the presence of the AjaxControlToolkit in the project, as it overrides some MS AJAX methods related to event handling: https://docs.telerik.com/devtools/aspnet-ajax/controls/window/troubleshooting/common-issues#onclientclose-is-not-fired.

You can also make sure the old content is not seen by setting ShowContentDuringLoad to false.
