    <p>I have trying to Edit and Update my GridView in bulk. I have generated a <code>CheckBox</code> in the first column of my <code>GridView</code>. It works something like this: If I check a particular row in the <code>GridView</code>, the row gets editable. Like this I can check as many rows I want to edit the <code>GridView</code>. I have given a universal button called UPDATE, once after editing all the rows, and click on this button, the <code>GridView</code> is updated looping in each row checking for CheckBox.Check.</p> <p>The issue I am facing here is that, when I click on any <code>CheckBox</code> in the <code>GridView</code> row, I am not getting <code>TextBox</code>. I am trying to convert <code>Label</code> to <code>TextBox</code> on checking a <code>CheckBox</code> in the <code>GridView</code>.</p> <p>So when I check a row, the text corresponding to <code>Label</code> template for that cell goes invisible according to my program, but fails to get the <code>TextBox</code> with the value of that cell.</p> <p>The code I have tried is this:</p> <pre><code>protected void OnCheckedChanged(object sender, EventArgs e) { bool isUpdateVisible = false; CheckBox chk = (sender as CheckBox); if (chk.ID == "chkAll") { foreach (GridViewRow row in GridView3.Rows) { if (row.RowType == DataControlRowType.DataRow) { row.Cells[0].Controls.OfType&lt;CheckBox&gt;().FirstOrDefault().Checked = chk.Checked; } } } CheckBox chkAll = (GridView3.HeaderRow.FindControl("chkAll") as CheckBox); chkAll.Checked = true; foreach (GridViewRow row in GridView3.Rows) { if (row.RowType == DataControlRowType.DataRow) { bool isChecked = row.Cells[0].Controls.OfType&lt;CheckBox&gt;().FirstOrDefault().Checked; for (int i = 3; i &lt; row.Cells.Count; i++) { row.Cells[i].Controls.OfType&lt;Label&gt;().FirstOrDefault().Visible = !isChecked; if (row.Cells[i].Controls.OfType&lt;TextBox&gt;().ToList().Count &gt; 0)//this condition is not satisfying when I debug the program. what is wrong in this line? { row.Cells[i].Controls.OfType&lt;TextBox&gt;().FirstOrDefault().Visible = isChecked; } if (isChecked &amp;&amp; !isUpdateVisible) { isUpdateVisible = true; } if (!isChecked) { chkAll.Checked = false; } } } } UpdateGrid.Visible = isUpdateVisible; } </code></pre> <p>The aspx code is:</p> <pre><code>&lt;asp:GridView ID="GridView3" runat="server" AutoGenerateColumns="False" DataKeyNames="Location_Profile_Name"&gt; &lt;Columns&gt; &lt;asp:TemplateField&gt; &lt;HeaderTemplate&gt; &lt;asp:CheckBox ID="chkAll" runat="server" AutoPostBack="true" OnCheckedChanged="OnCheckedChanged" /&gt; &lt;/HeaderTemplate&gt; &lt;ItemTemplate&gt; &lt;asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="true" OnCheckedChanged="OnCheckedChanged" /&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:TemplateField HeaderText="Location_Profile_Name" SortExpression="Location_Profile_Name"&gt; &lt;ItemTemplate&gt; &lt;asp:Label ID="Label1" runat="server" Text='&lt;%# Bind("Location_Profile_Name") %&gt;'&gt;&lt;/asp:Label&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:TemplateField HeaderText="Home_Profile" SortExpression="Label10"&gt; &lt;ItemTemplate&gt; &lt;asp:Label ID="Label2" runat="server" Text='&lt;%# Bind("Home_Profile") %&gt;'&gt;&lt;/asp:Label&gt; &lt;/ItemTemplate&gt; &lt;EditItemTemplate&gt; &lt;asp:TextBox ID="TextBox1" runat="server" Text='&lt;%# Bind("Home_Profile") %&gt;'&gt;&lt;/asp:TextBox&gt; &lt;/EditItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt;&lt;/asp:GridView&gt; </code></pre> <p>I have commented the issue I am facing in the program above. Kindly help.</p>

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.
