I have replaced the radAjaxManager for ASP.Net with the one of the prometheus controls. Now the click event of a button no more fires if the button is included in the manager and a update control is defined. With the "old" radAjaxManager everything worked fine.
Any ideas?

Hello Markus,

The button requires updated control when ajaxified by the manager (see point 5 here) and this simple scenario works just fine with the Prometheus RadAjaxManager as well:

Let us know if you need further assistance.

Hi Markus,

Could you post the markup of the problematic page here or open a formal support ticket with a sample application that we can investigate locally?

Looking forward to your reply.


Kind regards,

Here is the code, the example uses the Northwind database. In order to get it work you must modify the connect string in "Page_Load" for your needs. Just select an item from list and click the "Select" button. As you can see the selected row will not be shown on bottom of grid. If you enable the button by default it is working and it is also working if you use the NON prometheus radAjaxManager and radGrid.

Hello Markus,

In your scenario you will need to handle the AjaxSettingCreating server-side event of the AjaxManager and set the UseSubmitBehavior property of the Button initator to true:

protected void RadAjaxManager1_AjaxSettingCreating(object sender, Telerik.Web.UI.AjaxSettingCreatingEventArgs e) 
    Button initiator = e.Initiator as Button; 
    if (initiator != null) 
    { 
        initiator.UseSubmitBehavior = true
    } 


Hope this helps.


All the best,
Manuel
