    <p>I am making an editable <code>GridView</code>, but my problem is that whenever I click on a button nothing happens. When I click a second time I see what happened during the previous click. </p> <h3>aspx</h3> <pre><code> &lt;%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" EnableEventValidation="true" CodeBehind="Default.aspx.cs" Inherits="BeheerSysteemWeb._Default" %&gt; &lt;asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"&gt; &lt;/asp:Content&gt; &lt;asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"&gt; &lt;h2&gt; &lt;asp:GridView ID="GridView1" runat="server" onrowcancelingedit="GridView1_RowCancelingEdit" onrowediting="GridView1_RowEditing" onrowupdating="GridView1_RowUpdating" AutoGenerateColumns="False"&gt; &lt;Columns&gt; &lt;asp:CommandField ButtonType="Button" ShowEditButton="true" ShowCancelButton="true" /&gt; &lt;asp:TemplateField HeaderText="36"&gt; &lt;EditItemTemplate&gt; &lt;asp:TextBox runat="server" ID="txtSpoor" Text="TramNummer" /&gt; &lt;/EditItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; &lt;/h2&gt; &lt;/asp:Content&gt; </code></pre> <h3>Codebehind</h3> <pre><code> namespace BeheerSysteemWeb { public partial class _Default : System.Web.UI.Page { List&lt;string&gt; leeg = new List&lt;string&gt;(); protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { LoadData(); } } private void LoadData() { leeg.Add(""); leeg.Add(""); leeg.Add(""); leeg.Add(""); GridView1.DataSource = leeg; GridView1.DataBind(); } protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) { GridView1.EditIndex = e.NewEditIndex; } protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e) { e.Cancel = true; GridView1.EditIndex = -1; } protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e) { GridViewRow row = GridView1.Rows[e.RowIndex]; TextBox txtSpoor = (TextBox)row.FindControl("txtSpoor"); e.Cancel = true; GridView1.EditIndex = -1; } } } </code></pre> <p>How can I get the button to work in ASP.NET ?</p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
