</asp:UpdatePanel>

Any ideas????

Answer 1

Put the asp:Textbox inside the UpdatePanel as that is the control that you want to update during postback...

Answer 2

Put the textbox inside the update panel. That's what the panel is for.

Answer 3

A PostBackTrigger will post the page for you:

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

<Triggers>
     <asp:PostBackTrigger ControlID="Button1" />
</Triggers>

NOTE: As others have mentioned, depending on your requirements, you could just put the TextBox in the UpdatePanel.

Answer 4

You should put the update panel around the TextBox. The button can be inside the update panel but if you don't want it inside the update panel you can use the update panel's triggers and set it the button ID.

Answer 5

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" />
