    copied!<p>This should be simple but I am losign this battle. I have a gridview. All I want is for the user to be able to enter names into it, click add and have the values added. I also want to use the delete command, should they make a mistake. I have tried Eval and Bind. But something keeps going wrong. </p> <p>I have a textbox in the to enter the first one. And alos a textbox in the footer to enter values. When they are entered, they are added to a generic list (string) and re-bound to the gridview. But it fails when it attempts to bind to the list. </p> <p>In the markup below, DataItem.Alias &lt;- Alias is actually the name of the generic list</p> <pre><code> &lt;asp:GridView ID="gvAlias" runat="server" ShowFooter="True" AutoGenerateColumns="false" ShowHeaderWhenEmpty="True" ShowHeader="False" &gt; &lt;Columns&gt; &lt;asp:TemplateField&gt; &lt;ItemTemplate&gt; &lt;%# DataBinder.Eval(Container, "DataItem.Alias")%&gt; /&gt; &lt;/ItemTemplate&gt; &lt;FooterTemplate&gt; &lt;asp:TextBox ID="txtFooterAlias" runat="server" /&gt; &lt;asp:LinkButton ID="btnFooterAdd" runat="server" OnClick="AddFromFooter"&gt;Add New&lt;/asp:LinkButton&gt; &lt;/FooterTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:CommandField ShowDeleteButton="True" /&gt; &lt;/Columns&gt; &lt;EmptyDataTemplate&gt; &lt;asp:TextBox ID="txtEmptyAlias" runat="server" /&gt; &lt;asp:LinkButton ID="btnEmptyAdd" runat="server" OnClick="AddFromEmpty"&gt;Add New&lt;/asp:LinkButton&gt; &lt;/EmptyDataTemplate&gt; &lt;/asp:GridView&gt; </code></pre> <p>and the code behind...</p> <p>Public Sub BindGridView()</p> <pre><code>Dim oThis As This 'this is a class I have that has a property which is a generic list of string gvAlias.DataSource = oThis.Alias.ToArray gvAlias.DataBind() </code></pre> <p>End Sub</p>
