    <p>I have custom upload control. The control has gridview with the uploaded documents and the first column has checkbox for selecting documents I want to delete by clicking Delete button. The upload control is contained in other UserControls almost everywhere in the application and works properly, except at one control. The problem is when I check some document for deleting, when the code executes the checked property of the checkbox is false.</p> <pre><code>&lt;asp:GridView ID="gvFiles" runat="server" AutoGenerateColumns="false" ShowHeader="true" CssClass="DataGrid" Width="100%" OnRowDataBound="gvFiles_RowDataBound"&gt; &lt;HeaderStyle HorizontalAlign="left" CssClass="UploadControlGridHeader" /&gt; &lt;RowStyle CssClass="dlcell" /&gt; &lt;EditRowStyle CssClass="dlsell" /&gt; &lt;Columns&gt; &lt;asp:TemplateField HeaderText="Delete"&gt; &lt;ItemStyle Width="8%" HorizontalAlign="Center" /&gt; &lt;ItemTemplate&gt; &lt;asp:CheckBox ID="chkFile" runat="server" /&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; </code></pre> <p>and this is the delete button event</p> <pre><code>protected void btnDelete_Click(object sender, EventArgs e) { for (int i = 0; i &lt; gvFiles.Rows.Count; i++) { CheckBox chk = (CheckBox)gvFiles.Rows[i].Cells[0].FindControl("chkFile"); if (chk.Checked) { // If file is marked/checked to be deleted // then delete it. DeleteFile(i); } } Session[KEY_VIEWSTATEFILES] = this.FileList; // Repopulate gridview BindToGridView(); // Call command to keep same visible screen. CustomCommandEventArgs command = new CustomCommandEventArgs(COMMAND_FILE_DELETED, null); OnHappyCommand(command); } </code></pre>

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.
