I'm going crazy and I'm not sure what the problem is.

Here is my situation:
My main page (aspx) contains two usercontrol (ascx)
first one is basically a tree. second one is a radgrid and some textbox I fill on row selection itemcommand.

The second one is dinamically loaded depending on tree's node value has a radgrid. I mean, I load different ascx by the node's value but they all are a radgrid and textboxes.

main Page

<td>

<qsf:RTV runat="server" ID="CatTree1" ></qsf:RTV>

</td>

<td style="width:80%;vertical-align:top">

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<asp:PlaceHolder ID="PlaceHolder_UC" runat="server"></asp:PlaceHolder>

</ContentTemplate>

<Triggers>

<asp:AsyncPostBackTrigger ControlID="CatTree1" />

</Triggers>

</asp:UpdatePanel>

</td>

PlaceHolder_UC is dinamically loaded this way

function AAAAAAA()....

Dim UControl As Control

If ....

controlPath = "Arrangements2.ascx"

End If

UControl = CType(LoadControl(controlPath), UserControl)

If controlPath <> "" Then

If Not (UControl Is Nothing) Then

'ascx dinamically attached

PlaceHolder_UC.Controls.Clear()

PlaceHolder_UC.Controls.Add(UControl)

.....

Dim myUC As ASP.Arrangements2 = DirectCast(tempControl, ASP.Arrangements2)

'here I Call function on second ascx, fill radgrid whit data

myUC.InitControl(value)

....

End If

I call AAAAAAA on the nodeclick event catch on the aspx raised by my first ascx
Ascx2 radgrid is filled, i click on the rows, itemcommand fires, I fill the textboxes. everything is ok

here come my problem
I click on a different tree's node, AAAAAAA is called, ascx2 radgrid is filled with a new set of data, i click on the rows and itemcommand never fires

here's my ascx2 (summaring)

<asp:UpdatePanel ID="UpdatePanelAscx" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<telerik:RadGrid ID="RadGridArrangement"

runat="server"

OnItemCommand="RadGridArrangement_ItemCommand"

>

.....

<ClientSettings enablePostBackOnRowClick="True">

<Selecting AllowRowSelect="True" />

</ClientSettings>

.........

<Triggers>

<asp:AsyncPostBackTrigger ControlID="RadGridArrangement" EventName="OnItemCommand" />

</Triggers>

</asp:UpdatePanel>

Thank you
