[Amol]

Hello,

Is it possible in AjaxPanel same functionality as Update Panel having update mode=always

<telerik:RadAjaxPanel id="RadAjaxPanel1" runat="server"
       EnableAJAX= "True">
    </telerik:RadAjaxPanel>

Thanks,
Amol

Hello Amol,

To achieve your goal you need to wire the OnAjaxSettingCreating event and set the UpdateMode property of the update panel which is about to be generated. Here is a code snippet which illustrates the approach:

    protected void RadAjaxPanel1_AjaxSettingCreating(object sender, AjaxSettingCreatingEventArgs e)
    {
        e.UpdatePanel.UpdateMode = UpdatePanelUpdateMode.Always;
    }

What about UpdateMode="Conditional" & ChildrenAsTriggers="False"? Do they follow same concept?

Hello Saed,

When the UpdateMode is set to "Always" the content of the update panel will update when some of the controls in it makes a postback (or if there is a registered control which will make an asynchronous call).

The ChildrenAsTriggers property determines whether postbacks from a child control in an UpdatePanel result in its contents being refreshed. A scenario where you might set ChildrenAsTriggers to false is when you have two UpdatePanel controls and you want a postback from the first panel to update the content of the second panel but not update its own content. For example, the first panel might be a list of products to buy and the second panel might be a shopping cart.

With respect my friend, that wasn't my question. I'm very well aware of ASP UpdatePanel and how it works.

My question was in reference to RadAjaxPanel. In the initial post, you kindly showed how to set AjaxPanel UpdateMode to always. Based on that, does AjaxPanel have other UpdateModes such as Conditional (as the case with ASP UpdatePanel)? In the same context, does it have something similar to  ChildrenAsTriggers?

The reason I'm asking is I couldn't find any related property(ies) to control UpdateMode when replaced ASP UpdatePanel with RadAjaxPanel.

Hope this clarifies.

Hello Saed,

Please excuse me for the misunderstanding your question.

In general the RadAjaxPanel is a wrapper of the UpdatePanel. Thus if you reference the e.UpdatePanel, you actually retrieve the UpdatePanel wrapped in the RadAjaxPanel. Hence you can set all available to one UpdatePanel properties. Here is a code snippet showing what I mean:

    protected void RadAjaxPanel1_AjaxSettingCreating(object sender, AjaxSettingCreatingEventArgs e)
    {
        UpdatePanel updatePanel = e.UpdatePanel; //getting reference to the UpdatePanel
        updatePanel.UpdateMode = UpdatePanelUpdateMode.Conditional; //this is te default value for the RadAjaxPanel
        updatePanel.ChildrenAsTriggers = false;
    }

Kind regards,

Hello Rohan,

The RadAjaxPanel does not have Update method as the asp UpdatePanel control. However you could manually call ajaxRequest() on the client for this RadAjaxPanel and in the server OnAjaxRequest event update the needed control.
