Hi,

I am trying out the AjaxLoadPanel for the first time. I want a wait msg to appear after I click my search image-button while my Radgrid is loading. This works the first time I search after loading the page, but not the second time. I am sure I am making a beginner mistake somewhere.

btw. If I create another AjaxSetting with my ImgButton as trigger and my Radgrid as updatecontrol then I get a error complaining that my control contains code blocks. This happens even if I wrap it with an asp:panel, and yes I have to script in my header.

Hope someone can help me out here :-)

Axel

Hi Pavlina

thanks for the reply.

Did you look at the main issue in my issue i.e. upload panel only showing up on initial search (when search btn is pressed right after pageload)?

On the codeblock issue, I have scrips like these inside my radgrid

    
            <NoRecordsTemplate> 
        
            <span class="information center"><%= GetLocalResourceObject("NothingFound").ToString() %></span>  
        
            </NoRecordsTemplate>

These along with other like (HeaderText="<%$ Resources:HeaderName %>") may be causing problems. Wrapping the Radgrid with Radcodeblock does not seem to be the solution.

Axel.
