    <p>Need some help to solve this.</p> <p>I have a gridview and inside the gridview I have a checkbox and after clicking the checkbox, I am doing a postback event and trying to update this particular row only on the database.</p> <p>This is my gridview checkbox code. see the OnCheckedChanged.</p> <pre><code>&lt;asp:TemplateField HeaderText="Sample"&gt; &lt;ItemTemplate&gt; &lt;asp:CheckBox runat="server" ID="chkSample" Checked='&lt;%# Bind("Sample") %&gt;' OnCheckedChanged="UpdateSupplyLed" AutoPostBack="True"&gt; &lt;/asp:CheckBox&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; </code></pre> <p>Code: </p> <pre><code>protected void UpdateSupplyLed(object sender, EventArgs e) { foreach (GridViewRow di in SamplingGridView.Rows) { CheckBox chkBx = (CheckBox)di.FindControl("chkSample"); if (chkBx != null &amp;&amp; chkBx.Checked) { //update database logic here. } } } </code></pre> <p>The above code works fine but it is getting me all the checkboxes that are checked irresepective of the one that I just checked. I don't want all of them.</p> <p>How can I get the only one row value that have been just checked. Some of the rows might have been checked already because the status is true for those records and I don't want to update those records.</p> <p>I think I've got my question right!</p> <p>Update: The answer is: </p> <pre><code>protected void UpdateSupplyLed(object sender, EventArgs e) { CheckBox chkSampleStatus = sender as CheckBox; bool sample = chkSampleStatus.Checked; GridViewRow row = chkSampleStatus.NamingContainer as GridViewRow; TextBox txtId = row.FindControl("Id") as TextBox; int id = Int32.Parse(txtId.Text); } </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.
