<ContentTemplate>
    <asp:Button ID="Button1" runat="server" Text="Button" />

</asp:UpdatePanel>

Any ideas????

I want the TextBox out side the SAME UpdatePannel.Button should be in the UpdatePannel.can i have 2 UpdatePannels.one for the TextBox and another for the Button????

Answer 1

Actually the TextBox should be inside the update panel or outside with an update panel's trigger

<asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
    <ContentTemplate> 
        <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
        <asp:Button ID="Button1" runat="server" Text="Button" />   
    </ContentTemplate>
</asp:UpdatePanel>

OR

<asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
    <ContentTemplate> 
        <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
    </ContentTemplate>
    <Triggers>     
        <asp:AsyncPostBackTrigger ControlID="Button1" />     
    </Triggers> 
</asp:UpdatePanel>
<asp:Button ID="Button1" runat="server" Text="Button" />
