How to bing controls inside of AJAXLoadingTemplate?

[Kseniya Garipova]

Hello!

I want to place a user control inside of AJAXLoadingTemplate. (The purpose is to show localized images depending on current culture)
But for dealing this datagrid data I use RadGrid_NeedDataSource event and, thus, do not call DataBind() method explicitly. As a result - data in AJAXLoadingTemplate is not bound and there is no images while loading.
What can I do in order to bind data in AJAXLoadingTemplate?

Thanks!

Hi Kseniya Garipova,

I suggest, if appropriate in your scenario, to try calling explicitly UserControl's Bind method in its PageLoad event. Please give it a try and let us know how it went.

Hi Rosen,

I tried, but no luck. Here is the code from RadGrid:
<AJAXLoadingTemplate>
    <ems:DivLoading ID="divLoading" runat="server" />
</AJAXLoadingTemplate>

Here is the code of DivLoading control:
<asp:Image ID="img" runat="server" ImageUrl='<%# LoadingSrc %>' />

protected void Page_Load(object sender, EventArgs e)
{
    this.DataBind();
}

Page_Load() is called, but at those moment control "img" doesn't exist yet. On the other hand, if I place DivLoading in any other place (including AjaxLoadingPanel for using with RadAjaxManager) - it works well.
Am I doing something wrong?

Hello Kseniya,

I have attached a simple page which demonstrates the described approach. Please give it a spin and let us know how it went. Maybe I'm missing something obvious.

Hello Rosen,
Thank you! It works.
It was I who missed something obvious. :)
