Rebinding a grid in NestedViewTemplate

[Richard Boarman]

I have a RadGrid (RadGrid1) that has a nestedViewTemplate. In this NestedViewTemplate, another grid (RadGrid2) is loaded.
RadGrid2 has an imagebutton in each row that opens a RadWindow, where the user can make modifcations to the row in RadGrid2.
When the RadWindow is closed (OnClientClose="refreshGrid" ), this function is run

function refreshGrid() {
        var args = null;
        args = document.getElementById("inpHidden").value;
        if (args) {
            var mgr = $find("<%= RadAjaxManager1.ClientID %>");
            if (mgr) {
                mgr.ajaxRequest(args);
            }
        }
    }

The RadAjaxManager1_AjaxRequest method rebinds the grid in the NestedViewTemplate without reloading the main grid RadGrid1. This is the desired behavior and works fine. However, if I click on the image button again, the function can no longer find a reference to RadAjaxManager1, which is on the control that holds the Main grid

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid2" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="RadGrid2">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid2" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadAjaxPanel ID="RadAjaxPanel4" runat="server" Width="100%" LoadingPanelID="RadAjaxLoadingPanel4">
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel4" runat="server"">
telerik:RadAjaxLoadingPanel>
<telerik:RadGrid ID="RadGrid1" ....

Any idea why the manager can no longer be found?

Hi Richard,

Does using a bit different syntax, namely:

C#

var mgr = $find("<%= RadAjaxManager.GetCurrent(this).ClientID %>");

or
VB.NET

var mgr = $find("<%= RadAjaxManager.GetCurrent(Me).ClientID %>");

makes a difference? Also it will be helpful if you post your aspx markup code with the related code behind.

Looking forward for your reply.

Best wishes,
