Why it always return to the original place?

<asp:ScriptManager ID="ScriptManager1" runat="server" />
<cc1:DragPanelExtender ID="DragPanelExtender1" runat="server" TargetControlID="Panel1"
DragHandleID="Panel2">
</cc1:DragPanelExtender>
<asp:Panel ID="Panel1" runat="server" Height="300" Width="200">
<asp:Panel ID="Panel2" runat="server" Height="25" Width="200" BackColor="Black">
</asp:Panel>
Test</asp:Panel>

I would like the Panel1 can be dragged and stay the place where I drop it.

How to do that?

I believe the body of the page has to have been assigned some sort of physical dimension:

See point #23 and Listing 6 of this article:

Many thanks for replying.

why Timer always reload updatepanel, is it right?

I tried to use timer to reload updatepanel, code like this

<atlas:TimerControl runat="server" ID="timer" Interval="5000"/>

<atlas:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
my controls...

</ContentTemplate>
</atlas:UpdatePanel>

right, I don't define trigger there. But even with code like that, the updatepanel still reload every 5 seconds, why it works this way?

thanks

I think I have found answer.

hello.

well, as you might have guesses by know, you have to set the mode property of the panel to conditional.
