RadAjaxManagerProxy on programmatically created usercontrol

Question

Situation:

I have created a custom webusercontrol. The user control is fully created in code .

It consists of a radgrid and radcombox.

The radcombox is filled with database tables, when the user select a table the data
needs to be shown in the radgrid.

This usercontrol is added to a aspx page. Everything works perfectly.

Here comes the problem:

I want a radajaxloadingpanel to be shown on the radgrid while it rebinds, using a radajaxmanagerproxy control. This doesn't work until I hit the refresh button or a page next or prev of the radgrid. Then everything works fine.

I know the combobox works because the data does change only the loadingpanel isn't shown.

Does anybody have a clue on how to solve this, a work around or a suggestion I can look into?

Answer 1

Finally got it to work. I did something wrong in the creation life cicle:

now i have it like this. And it works ;)

   public class CustumControl
     implements CompositeControl

     Private RadAjaxLoadingPanel1 As New RadAjaxLoadingPanel
     Private RadAjaxManagerProxy1 As New RadAjaxManagerProxy
      ....
      Protected Sub Control_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
          Me.Controls.Add(RadAjaxLoadingPanel1)
          Me.Controls.Add(RadAjaxManagerProxy1)

          With RadAjaxManagerProxy1.AjaxSettings  
               .AddAjaxSetting(...) 
          End with 
      End Sub
      ....

      Protected Overrides Sub CreateChildControls()
        'Set properties controls and add themwill
      End Sub
   end class

Hope this will help other people with simular problems.
