my situation is based on this example: http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=grid

the main differences in my scenario are that i am calling the radwindow from a grid hosted in an ajax control toolkit tab form. i have a radajaxmanager declared on the page outside of the scope of the tab. the first tab contains a grid whose selection drives the data selection results of two grids on another tab and 1 grid on a third tab. the third tab contains a radwindowmanager and radwindow which is opened from the grid. a selection is made whereupon a button click event of the radwindow (aspx.cs) writes the data and then calls for a refresh of the parent grid as follows:
ClientScript.RegisterStartupScript(Page.GetType(), "registerkey", "CloseAndRebind('Registration');", true);

which calls this from the radwindow (aspx) :
function CloseAndRebind(args) {
    GetRadWindow().BrowserWindow.refreshGrid(args);
    GetRadWindow().close();
}

which calls this from parent page's tab (aspx)
function refreshGrid(arg) {
if (!arg) {
var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");
ajaxManager.ajaxRequest();
}
else {
var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");
ajaxManager.ajaxRequest(arg);
}
}

which finally calls this in the aspx.cs

 

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
   RadGrid1.Rebind();
    RadGrid2.Rebind();
   RadGrid3.Rebind();
}

 

tab2 (with 2 grids) has radajaxmanagerproxy and the tab works well. tab3 with radgrid3 works ok when updated by tab1 grid1 but not when updated from the radwindow. i have tried radajaxmanagerproxy on tab 3 grid 3 with no success with and without a radajaxpanel.

i have never been able to debug into the ajaxrequest - not sure if it is possible. i have configured radajaxmanagerproxy through its editor but  it does not see the radajaxmanager.

any ideas about why tab3 will not rebind?

i don't need to update all of these grids each time but for now i am using this bloated code until i can get tab 3 to update properly...

i am quite embarrassed to report that the culprit was a missing element in the radajaxmanager:
OnAjaxRequest="RadAjaxManager1_AjaxRequest"

it was there at one time but went missing in action......the moral of the story is don't forget to check if the damned thing is plugged in.
