RadAjaxManagerProxy in WebUserControl issue

[hkdave95]

Hi

I have a WebUserControl that is my edit form for a grid.

I have two list boxes with add and remove buttons.

When I select add a selected item moves from the left hand box to the right hand box.

This works. However, when the ajax call is finished the loading panel remains on the screen and any button that is pressed from that point onwards causes a Javascript error.

The error reads: Microsoft JScript runtime error: 'this.get_element()' is null or not an object.

The following fo rthe grid is on my main page ...

                <telerik:AjaxSetting AjaxControlID="rgStockMaintenance">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="rgStockMaintenance" LoadingPanelID="ralpDefault" />
                    </UpdatedControls>
                </telerik:AjaxSetting>

And the following is on my user control ...

<telerik:RadAjaxManagerProxy ID="ramprgStockMaintenance" runat="server" EnableViewState="true">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="btnAddCategory">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="lbxUnselectedCategories" LoadingPanelID="ralprgStockTransactions" />
                <telerik:AjaxUpdatedControl ControlID="lbxSelectedCategories" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="btnRemoveCategory">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="lbxUnselectedCategories" LoadingPanelID="ralprgStockTransactions" />
                <telerik:AjaxUpdatedControl ControlID="lbxSelectedCategories" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="rgStockTransactions">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="rgStockTransactions" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>

I need to Ajaxify the Grid and the controls am I doing it incorrectly ?

David,

    Have you tried to EnableAjax on the grid itself?  It will ajaxify the grid edit usercontrol also.  I use many grids with edit controls and they all work fine.  If this doesn't work, please include more code so we can see what else may be causing it.

One other thing.  Turn off the ajax manager stuff for the grid when you turn on the grid ajax.

Hi

EnableAjax=true on the grid itself is not an option.

It does not work on the page that I have setup. It breaks with a javascript error. I was advised by Telerik to turn this setting off.

I have to use RadAjaxManager for ajax with regards to the grid.

Kind Regards

David
