    <p>I am trying to update a database using the GridView edit, update CommandField. I have two editable fields which are displayed as text boxes when in edit mode. When clicking submit, I am trying to put the text box values into variables to work with, but I am unable to access them. The two column names are "EOR" and "CategoryName". I have found several suggestions on other forums to try something like:</p> <pre><code>protected void ResultGridView_RowUpdating(object sender, GridViewUpdateEventArgs e) { TextBox txtEor = (TextBox)myGridName.Rows[e.RowIndex].FindControl("EOR"); </code></pre> <p>When I debug the program, txtEor is always null. The only thing i can think of is that I am not referencing the cell properly. I set the Headertext, AccessibleHeaderText, DataField, and SortExpression to "EOR" but it still just comes up null.</p> <p>Any help would be greatly appreciated!</p> <p>asp for the gridview:</p> <pre><code>&lt;asp:GridView ID="grdEOR" runat="server" BackColor="White" BorderColor="#999999" OnPageIndexChanging="grdEor_PageIndexChanging" BorderStyle="Solid" BorderWidth="1px" CellPadding="3" ForeColor="Black" GridLines="Vertical" AllowPaging="True" PageSize="15" AutoGenerateColumns="False" onrowediting="grdEOR_RowEditing" onrowcancelingedit="grdEOR_RowCancelingEdit" onrowupdating="grdEOR_RowUpdating" onrowdeleting="grdEOR_RowDeleting" ShowFooter="True"&gt; &lt;PagerSettings Mode="NumericFirstLast" /&gt; &lt;Columns&gt; &lt;asp:BoundField DataField="EORCategoryID" HeaderText="EORCategoryID" SortExpression="EORCategoryID" ReadOnly="True"&gt; &lt;/asp:BoundField&gt; &lt;asp:BoundField DataField="EOR" HeaderText="EOR" SortExpression="EOR" AccessibleHeaderText="EOR"/&gt; &lt;asp:BoundField DataField="CategoryName" HeaderText="CategoryName" SortExpression="CategoryName" /&gt; &lt;asp:CommandField ButtonType="Button" ShowDeleteButton="True" ShowEditButton="True" /&gt; &lt;/Columns&gt; &lt;FooterStyle BackColor="#CCCCCC" /&gt; &lt;PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" /&gt; &lt;SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" /&gt; &lt;HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" /&gt; &lt;AlternatingRowStyle BackColor="#CCCCCC" BorderColor="Black" BorderStyle="Solid" BorderWidth="5px" /&gt; &lt;/asp:GridView&gt; </code></pre>

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).
