I found the solution!
User Control Code:
<asp:timer runat="server" id="UpdateTimer1" interval="60000" ontick="UpdateTimer1_Tick" xmlns:asp="#unknown" />
<asp:timer runat="server" id="UpdateTimer2" interval="60000" ontick="UpdateTimer2_Tick" xmlns:asp="#unknown" />
<asp:table id="Table1" runat="server" width="100%" height="100%" gridlines="Both" xmlns:asp="#unknown">
CellPadding="2" CellSpacing="2" >
<asp:tablerow id="TableRow1" width="100%" height="100%">
<asp:tablecell id="cellScroller1" runat="server" width="50%" height="100%">
<asp:updatepanel runat="server" id="UpdatePanel1" updatemode="Conditional">
<triggers>
<asp:asyncpostbacktrigger controlid="UpdateTimer1" eventname="Tick" />
</triggers>
<contenttemplate>
<marquee onmouseover="stop();" onmouseout="start();" scrollAmount="1" scrollDelay="30" direction="up">
<asp:label id="lblTextScroller1" runat="server" width="100%" height="100%" borderwidth="1px">scoller1 text</asp:label>
</marquee>
</contenttemplate>
</asp:updatepanel>
</asp:tablecell>
<asp:tablecell id="cellScroller2" runat="server" width="50%" height="100%" borderwidth="2px">
<asp:updatepanel runat="server" id="UpdatePanel2" updatemode="Conditional">
<triggers>
<asp:asyncpostbacktrigger controlid="UpdateTimer2" eventname="Tick" />
</triggers>
<contenttemplate>
<marquee onmouseover="stop();" onmouseout="start();" scrollAmount="1" scrollDelay="30" direction="up">
<asp:label id="lblTextScroller2" runat="server" width="100%" height="100%" borderwidth="1px">scoller2 text</asp:label>
</marquee>
</contenttemplate>
</asp:updatepanel>
</asp:tablecell>
</asp:tablerow>
</asp:table>
In Default.aspx:
<form id="form1" runat="server">
<asp:scriptmanager id="ScriptManager1" runat="server" xmlns:asp="#unknown" />
<div>
<asp:table id="Table2" runat="server" width="100%" height="100%" gridlines="Both" xmlns:asp="#unknown">
CellPadding="2" CellSpacing="2" >
<asp:tablerow id="TableRow2" width="100%" height="100%">
<asp:tablecell id="TableCell1" runat="server" width="50%" height="100%">
<uc:webusercontrol1 id="webUserControl1" runat="server" xmlns:uc="#unknown" />
</asp:tablecell>
</asp:tablerow>
</asp:table>
</div>
</form></form>
Thanks! :)
