Update the RadAjaxManager on condition.

[Lakshman]

Hi,

I am using Rad window which i am navigating other .aspx page on button click. There is a save functionality in the window, after closing. Calling this function in RadWindowManager.

function closeRadWindow() {
            $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest();
        }

the grids will be rebind. Working good with this code which mentioned below.  

Issue : grd1 and grd2 will be in one panel1 and grd3 is in another panel2. Condition is when Panel1 only visible (Panel2 is visible false ) then getting error : 

Microsoft JScript runtime error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_cphContent_ctl00_cphContent_wizPageInfo_grd3Panel'. If it is being updated dynamically then it must be inside another UpdatePanel.

Here is my code which i am using:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="grd1" UpdatePanelRenderMode="Inline" />
                    <telerik:AjaxUpdatedControl ControlID="grd2" UpdatePanelRenderMode="Inline" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="grd3" UpdatePanelRenderMode="Inline" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

Code Behind:

  protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
        {
            grd1.Rebind();
            grd2.Rebind();
            grd3.Rebind();
        }

Hello,

Note that you could not add control which is initially invisible on the page, to the RadAjaxManager settings. The initiator or the updated control should be always placed in a visible container so that the manager can locate it when necessary.
