    Updating GridPanel inside UpdatePanel

    Have an problems with updating grid inside UpdatePanel, I know its possible to do with JS but my goal is to initiate grid updating from server side on async postback initiated from another UpdatePanel control.

    <%@ Register Assembly="Ext.Net, Version=1.0.4093.32349, Culture=neutral, PublicKeyToken=2e12ce3d0176cd87"
    	Namespace="Ext.Net" TagPrefix="ext" %>
    
    <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
    	<ContentTemplate>
    		<asp:Literal ID="ltrTime" runat="server"></asp:Literal>
    		<ext:GridPanel ID="GridPanel1" runat="server"> .................... </ext:GridPanel>
    		</ContentTemplate>
    </asp:UpdatePanel>
    
    <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
    	<ContentTemplate>
    		<asp:Button ID="btnReload" runat="server" Text="Reload" OnClick="btnReload_OnClick" />
    	</ContentTemplate>
    </asp:UpdatePanel>
    protected void Page_Load(object sender, EventArgs e)
    {
    	ltrTime.Text = DateTime.Now.ToLongTimeString();
    }
    
    protected void btnReload_OnClick(object sender, EventArgs e)
    {
    	UpdatePanel1.Update();
    }
    As result Grid is disappearing after async postback. So how to do this correct ?

    Hi

    Try putting the gridpanel outside the updatepanel.
