RadAjaxManager updates all controls on post-back

[Jack]

I am trying to configure RadAjaxManager to update some RadDockZones in the page while not updating an IFrame.

When I configure RadAjaxManager like below, everything works fine and the RadDockZones do not cause the IFrame to update.

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="pnlDockZoneLeft">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="pnlDockZoneContent" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="pnlDockZoneContent">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="pnlDockZoneLeft" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

If I attempt to add another AjaxSetting to update the IFrame when the filter panel is updated, like so:

<telerik:AjaxSetting AjaxControlID="filterPane">
    <UpdatedControls>
        <telerik:AjaxUpdatedControl ControlID="pnlIFrame" />
    </UpdatedControls>
</telerik:AjaxSetting>

Any update to any of the Ajaxified controls causes the IFrame to update and lose its settings. Here is part of the response body from the post-back when I click on one of the RadDocks:

504|updatePanel|pnlDockZoneContentPanel|<div id="pnlDockZoneContent">

                                    <div id="dockZoneContent" class="RadDockZone RadDockZone_Outlook rdVertical" style="border-width:0px;min-width:10px;min-height:10px;display:none;">
        <!-- 2011.2.712.35 --><div class="RadDock RadDock_Default rdPlaceHolder" id="dockZoneContent_D" style="display:none;">
            <!-- -->
        </div><input id="dockZoneContent_ClientState" name="dockZoneContent_ClientState" type="hidden" />
    </div>

</div>|362|updatePanel|pnlIFramePanel|<div id="pnlIFrame" class="content" style="width:100%;">

                                    <iframe id="IFrame1" name="IFrame1" frameborder="0" marginwidth="0" scrolling="no" style="margin: 0; height: 525px" width="100%" height="100%" src="Profile.aspx?Redirect=True">
                                    </iframe>

</div>

Is there any way to set RadAjaxManager to only update panels that are in the UpdatedControls list and leave the ones that are ajaxified but not in the UpdatedControls list?

Hello Jack,

What does your page markup look like?

[Jack]

Essentially it boils down to this:

<td valign="top">
    <asp:Panel ID="LeftPane" runat="server" Width="172px" ScrollBars="none">
        <div>
            <table>
                <tr>
                    <td class="headerbg">
                        Navigation
                    </td>
                </tr>
                <tr>
                    <td>
                        <asp:Panel ID="pnlTabsModule">...</asp:Panel />
                    </td>
                </tr>
                <tr>
                    <td>
                        <asp:Panel ID="pnlDockZoneLeft">...</asp:Panel>
                    </td>
                </tr>
            </table>
        </div>
    </asp:Panel>
</td>
<td valign="top" align="left">
    <asp:Panel ID="MiddlePane" runat="server" ScrollBars="None" Width="816px" BackColor="#F8F8FF">
        <asp:Panel ID="filterPane">...</asp:Panel>
        <asp:Panel ID="pnlDockZoneContent">...</asp:Panel>
        <asp:Panel ID="pnlIFrame" runat="server" Width="100%" CssClass="content">
            <iframe name="IFrame1" id="IFrame1" runat="server" frameborder="0" marginwidth="0"
                scrolling="no" style="margin: 0; height: 525px" width="100%" height="100%" src="Profile.aspx?Redirect=True">
            </iframe>
        </asp:Panel>
    </asp:Panel>
</td>

With panels in multiple places I had to resort to using RadAjaxManager, but once I add the pnlIFrame into it everything starts reloading on every callback.

Hello Jack,

When you ajaxify container controls with RadAjaxManager in a manner where the container is initiator, then this container is wrapped in ajax panel which behaves like ASP:UpdatePanel with UpdateMode set to conditional. That is why each of the ajaxified panels in your case is updated on every ajax request. To overcome the issue, you can use RadAjaxPanel controls instead.
