In pageload, the grid view shows the correct image photo. After i click one of gridview column sorting, the grid does not show the image even the url is correct. Please help me this issue. I have searched other website and tried so many ways. But no resolved it yet after clicking grid view sorting.</p> <p>Here is designer page for grid view</p> <pre><code>&lt;asp:UpdatePanel ID="upBOMList" runat="server"&gt; &lt;ContentTemplate&gt; &lt;asp:Panel ID="Panel2" runat="server" ScrollBars="Vertical" Height="350px"&gt;

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.
