    <p>I want to keep some data which is checkhed in array list. I added checkbox to gridview and when i checked one of items. click event of checkbox runs for all so for example, I have two data when i click the any checkbox it runs 4 times, so it works for each one however, I want that only the item of one checkbox which is checked or unchecked is added to list. Is there solution or another solution</p> <pre><code> // checkbox click event protected void SelectedFriends_Click(object sender, EventArgs e) { bool isflag=false; foreach (GridViewRow row in GridView1.Rows) { // Access the CheckBox CheckBox cb = (CheckBox)row.FindControl("FriendSelector"); if (cb != null &amp;&amp; cb.Checked) { string friendname = GridView1.Rows[row.RowIndex].Cells[1].Text.ToString(); for (int i = 0; i &lt; list.Count; i++) { if (friendname.Equals(list[i].ToString())) { isflag = true; } } // if it is added previously don't add to list if(!isflag) { list.Add(friendname); } } else { string friendname = GridView1.Rows[row.RowIndex].Cells[1].Text.ToString(); for (int i = 0; i &lt; list.Count; i++) { if (friendname.Equals(list[i].ToString())) { isflag = true; } } // if it is not checked and it is in list delete it from list if(isflag) { list.Remove(friendname); } } } } &lt;asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" Font-Bold="True" Width="157px"&gt; &lt;Columns&gt; &lt;asp:TemplateField HeaderText="Select"&gt; &lt;ItemTemplate&gt; &lt;asp:CheckBox runat="server" id="FriendSelector" oncheckedchanged="SelectedFriends_Click" AutoPostBack="True"&gt; &lt;/asp:CheckBox&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:BoundField DataField="F_Name" HeaderText="Friend Name" SortExpression="F_Name" /&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; </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.
