I need some help with AJAX using Master Pages and the RadGrid when the EditMode="EditForms".

In my MasterPage.Master I have declared a RadAjaxManager with some AjaxSettings :

...........

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" >
  <AjaxSettings>
    <telerik:AjaxSetting AjaxControlID="RadGrid1">
    <UpdatedControls>
        <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
      </UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>

 

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Height="175px" MinDisplayTime="0" BackColor="ActiveBorder" Width="175px" Transparency="25"></telerik:RadAjaxLoadingPanel>

<asp:contentplaceholder id="Main" runat="server" >

</asp:contentplaceholder>

-------------------------------

In my Page.aspx i have A RadGrid control within a ContentPlaceHolder:

<

asp:Content ID="Content1" ContentPlaceHolderID="Main" runat="Server">

<

telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False"ShowStatusBar="true" OnNeedDataSource="RadGrid1_NeedDataSource" AllowMultiRowSelection="true" OnUpdateCommand="RadGrid1_UpdateCommand" AllowAutomaticInserts="false" >

 <SortingSettings SortedBackColor="Azure" />
<MasterTableView GridLines="None" EditMode="EditForms" AllowMultiColumnSorting="true" CommandItemDisplay="None" DataKeyNames="Document_ID" AllowFilteringByColumn="true">

<EditFormSettings CaptionFormatString="Document Details" UserControlName="DocumentDetails.ascx" EditFormType="WebUserControl" ><EditColumn UniqueName="EditCommandColumn1"></EditColumn>
</EditFormSettings>
</MasterTableView>
</telerik:RadGrid>

</

asp:Content>

--------------------------------

in my usercontrol pageDetails.ascx I have another datagrid:

<telerik:RadGrid ID="uxRadGridAllItems" PageSize="5" AllowPaging="True"runat="server" AllowSorting="True" GridLines="None" Width="450px" OnNeedDataSource="uxRadGridAllItems_NeedDataSource" OnItemCommand="uxRadGridAllItems_ItemCommand">
</telerik:RadGrid>

----------------------------------

My objective is to only refresh the "RadGridPageDetails" when it is clicked, however the whole page appears to be posted back everytime.
i have tried adding :

<telerik:AjaxSetting AjaxControlID="Main$RadGridPageDetails">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="Main$RadGridPageDetails" LoadingPanelID="RadAjaxLoadingPanel1" />
</UpdatedControls>
</telerik:AjaxSetting>

to the master page but this appears to be overridden by the main "RadGridpage" AjaxSetting.

So, in summary if the event is triggered on the main grid "RadGridPage", then I would like the RadGridPage control on the Page.aspx to be refreshed, and if the 
"RadGridPageDetails" control in the usercontrol is clicked I would like only that grid to be refreshed. How would I go about doing this?

Thanks

Hi Michael,

In order to ajaxify via separate ajax settings the grid in the content page of your master page and the user control, consider utilizing our RadAjaxManagerProxy control. Here are a couple of examples which illustrate its usage:

http://demos.telerik.com/ASPNET/Prometheus/Ajax/Examples/Manager/MasterPage/DefaultCS.aspx
http://demos.telerik.com/ASPNET/Prometheus/Ajax/Examples/Manager/UserControl/DefaultCS.aspx

Thus you will be able to "append" declaratively the additional settings to the main RadAjaxManager settings and define your own logic for ajax updates.
