    <p>Do not try to do both a click event handler and a command name, but instead just the command; like this:</p> <pre><code>&lt;ItemTemplate&gt; &lt;asp:ImageButton ID ="btnSave" runat="server" CommandName="SaveTitle" ImageUrl="~/images/download.jpg" CommandArgument='&lt;%# Container.DisplayIndex %&gt;' /&gt; &lt;/ItemTemplate&gt; </code></pre> <p>Also, make sure to set the <code>OnRowCommand</code> value in your grid view, like this:</p> <pre><code>&lt;asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" BorderColor="#336699" BorderStyle="Solid" BorderWidth="1px" CellPadding="3" Font-Names="Verdana" Font-Size="10pt" OnRowCreated="GridView1_RowCreated" DataKeyNames="titleid" EnablePersistedSelection="True" EnableViewState="False" OnRowCommand="GridView1_RowCommand"&gt; </code></pre> <p>Finally, implement the <code>GridView1_RowCommand</code> method, like this:</p> <pre><code>protected void GridView1_RowCommand(Object sender, GridViewCommandEventArgs e) { // If multiple buttons are used in a GridView control, use the // CommandName property to determine which button was clicked. if(e.CommandName == "SaveTitle") { // Do logic here to save title } } </code></pre> <hr> <p>UPDATE:</p> <p>Instead of using the <code>Container.DisplayIndex</code> for the command argument, use the <code>TitleID</code> value of the binding source (LINQ query), like this:</p> <pre><code>&lt;ItemTemplate&gt; &lt;asp:ImageButton ID ="btnSave" runat="server" CommandName="SaveTitle" ImageUrl="~/images/download.jpg" CommandArgument='&lt;%# Eval("TitleID") %&gt;' /&gt; &lt;/ItemTemplate&gt; </code></pre>

    1. COThat seems to have worked up to a point...I changed the CommandArgument to this: CommandArgument='<%#Eval("TitleID")%>' and I'm getting a key in the RowCommand method but it doesn't match the row I clicked on. In fact none of the keys match any of the rows displayed.

    2. COFor example...the first row I've verified in SQL should have a TitleID of 1027654. But when I click the imagebutton in the first row and check the value in the GridView1_RowCommand method...the e.CommandSource.CommandArgument the value is 1025695 which is wrong.

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.

SQuiL has stopped working due to an internal error.

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