RadAjaxManagerProxy & Grid EnablePostBackOnRowClick

[Joe Sanders]

Using Q1 2010 Beta (2010.1.216.40).

I have the following RadGrid:

<telerik:RadGrid ID="MyRadGrid" runat="server" DataSourceID="MyEntities"
    AllowSorting="True" AllowPaging="True" AutoGenerateColumns="True"
    OnSelectedindexChanged="Grid_SelectedIndexChanged"
    OnItemCreated="Grid_ItemCreated">

    <MasterTableView DataKeyNames="Id" DataSourceID="MyEntities" CommandItemDisplay="Top" EditMode="InPlace">
        <CommandItemTemplate>
            <telerik:RadToolBar runat="server" OnButtonClick="ToolBar_ButtonClick">
                <Items>
                    <telerik:RadToolBarButton runat="server" Text="Add" ImageUrl="~/Icons/Add.png" Visible='<%# MyRadGrid.SelectedIndexes.Count > 0 %>' />
                </Items>
            </telerik:RadToolBar>
        </CommandItemTemplate>
    </MasterTableView>

    <ClientSettings EnablePostBackOnRowClick="True">
        <Selecting AllowRowSelect="True" />
    </ClientSettings>
</telerik:RadGrid>

Everything works great, the RadToolBarButton is hidden until a row is selected (causing postback).  However when I add the RadAjaxManagerProxy below (this is on a page with a Master), the postback does not fire and the add button never becomes visible.

<telerik:RadAjaxManagerProxy runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="MyRadGrid">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="MyRadGrid" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>

Any suggestions would be apreciated.
Thanks,
Joe

Do you have a RadAjaxManager control on the master page? The RadAjaxManagerProxy requires a RadAjaxManager control to exist in the master page.

[Joe Sanders]

Yes, the master page starts off with the following:

<form id="MyForm" runat="server">
<telerik:RadScriptManager ID="ScriptManager" runat="server" />
<telerik:RadFormDecorator ID="FormDecorator" runat="server" />
<telerik:RadAjaxManager ID="AjaxManager" runat="server" />

Also, everything works properly when its inside of an ASP.net Update Panel.

Thanks,
Joe

Hi Joe,

The problem is most probably related to the fact that your application is running on the 4.0 version of the .Net Framework. Unfortunately RadAjaxManager does not work in Master/Content pages scenarios with the publicly available version of the framework due to a bug in it. You can read more details about this issue in this forum thread. To workaround it I can suggest to set the ClientIDMode of the page to "AutoID".

I can also inform you that the issue is fixed by Microsoft and everything should work for the final release of VS2010 and .Net 4.0.

Sincerely yours,
