Hi there. I think this is not telerik-specific but perhaps you might be able to help nontheless:

I have a radWindow with multiple Elements. One of them is a button, another is a "simple" radgrid
One of them is a Button that opens a new window. In that window an element can be changed in the database which is the datasource of the radgrid.

After closing that window I initiate a postback through the "OnClientClose"-Method.

Before opening that window the datasource of the radgrid had 5 Elements. After closing that window the datasource has 6 Elements (as wanted). I can see in the OnNeedsDataSource-Event that the datasource REALLY has that 6 elements. But in the frontend the new element is not shown.

I can close and reopen the window or reload it with response.redirect(response.url.toString()) but that of course kills all form entries made.

Any clue what causes that behaviour?

Ole

P.S:
Perhaps it might help to know that the NeedsDataSource-Event does not fire automaticly after closing the popup. I have to rebind manually for it to fire.

Hi Ole,

Try adding a setting to the RadAjaxManager where the RadAjaxManager updates the grid and see if it makes any difference:

<telerik:RadAjaxManager ID="infoManager" runat="server" OnAjaxRequest="InfoManager_AjaxRequest">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="infoManager">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="attGrid" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>
