Hey guys

After wasting a lot of time in finding a solution for this issue i´ve decided to start this post here and hopefully you can help me.

First of all i`ve to say that i`m trying to use a RadAjaxLoadingPanel for a user input site with several postback controls.

My solution works in a Master/Child scenario and is set up like follows:

  • There is one main master page
  • There are two nested master pages which are based on the main master page 
  • All other child sites are based on one of these nested master pages 

On my main master page i`m using a RadAjaxManager with following attributes:

<telerik:RadAjaxManager ID="ramMain" 
runat="server" 
        EnableHistory="True"
</telerik:RadAjaxManager> 

On my nested master pages i`m using a RadAjaxManagerProxy in combination with a RadAjaxLoadingPanel to ajaxifying all controls in the content place holders.

As example in my nested master page i want to ajaxify all postback controls in the left navigation column (cphContent_1_1_1_filter) which is updating the content column in the center. The content column (cphContent_1_1_1_content) is also updatet by itself:

    <telerik:RadAjaxManagerProxy ID="rampNestedMaster" runat="server"
    <AjaxSettings > 
        <telerik:AjaxSetting AjaxControlID="cphContent_1_1_1_filter" > 
            <UpdatedControls > 
                <telerik:AjaxUpdatedControl ControlID="cphContent_1_1_1_filter" LoadingPanelID="ralpMain" /> 
                <telerik:AjaxUpdatedControl ControlID="cphContent_1_1_1_content" LoadingPanelID="ralpMain" /> 
            </UpdatedControls> 
        </telerik:AjaxSetting> 
        <telerik:AjaxSetting AjaxControlID="cphContent_1_1_1_content"
            <UpdatedControls> 
                <telerik:AjaxUpdatedControl ControlID="cphContent_1_1_1_content" /> 
            </UpdatedControls> 
        </telerik:AjaxSetting> 
    </AjaxSettings> 
    </telerik:RadAjaxManagerProxy> 

The good news is that the RadAjaxProxy is really ajaxifying the controls in the left navigation column (cphContent_1_1_1_filter) which  is causing the postback and the content in the middle is also been updatet. 

But the RadAjaxLoadingPanel is never shown. At all it`s really curious.

I`ve only got the RadAjaxLoadingPanel to work with a simple RadAjaxPanel around my left navigation column. But with the RadAjaxManagerProxy it doesn`t work at all.

Are there any suggestions out there?

Regards

Chris

Hi Chris,

I checked the provided code, however I was not able to find the source of the problem there. Therefore I would ask you to open a formal support ticket and send us a runnable sample which we could review/debug locally and thus find what went wrong with it.

Hey guys

It´s about my previous post again. 

I may noticed another problem with RadAjaxManagerProxy and RadAjaxManager in a master --> child relation.

It seems to be that the RadAjaxManagerProxy doesn`t create any ajax history steps in your browser, if the EnableHistory attribute is set to True (in the RadAjaxManager on the master page), it`s the same scenario and code as in my previous post.

If i`m using a simple RadAjaxPanel for my navigation the history steps are created successfully.

You may please look up after that issue too?

Regards and thanks in  advance
