    copied!<p>I'm using a Gridview that is using datasource &amp; databinding. When i reload the page the gridview is updated but I want it to be on the buttonclick, but it's not working for me.</p> <p>The gridview inside the updatepanel:</p> <pre><code>&lt;asp:ScriptManager ID="ScriptManager1" runat="server"&gt; &lt;/asp:ScriptManager&gt; &lt;asp:UpdatePanel ID="upWall" runat="server" ChildrenAsTriggers="true" UpdateMode="conditional"&gt; &lt;ContentTemplate&gt; &lt;asp:GridView ID="gvWallPosts" runat="server" AutoGenerateColumns = "false" CaptionAlign="NotSet" CellPadding="5"&gt; &lt;Columns&gt; &lt;asp:TemplateField HeaderText="Avsändare"&gt; &lt;ItemTemplate&gt; &lt;%# GetSender((int)Eval("WallSender"))%&gt; &lt;br /&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:TemplateField HeaderText="Inlägg"&gt; &lt;ItemTemplate&gt; &lt;%# Eval("Post")%&gt; &lt;br /&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; &lt;/ContentTemplate&gt; &lt;/asp:UpdatePanel&gt; &lt;asp:TextBox ID="txtWall" runat="server" Height="105px" TextMode="MultiLine" Width="227px"&gt;&lt;/asp:TextBox&gt; &lt;br /&gt; &lt;asp:Button ID="btnWall" runat="server" Text="Posta" onclick="btnWall_Click" /&gt; </code></pre> <p>Code-behind:</p> <pre><code>protected void btnWall_Click(object sender, EventArgs e) { con.SendWallPost(con.GetId(Membership.GetUser().UserName), Convert.ToInt32(Request.QueryString["ID"]), txtWall.Text); //This method is sending the post upWall.Update(); } </code></pre> <p>So, I want the updatepanel to be updated on the ButtonClick, I don't want to reload the whole page to see the result</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
