    <p>I am having 2 radio buttons on my web form namely <code>Radio1</code> and <code>Radio2</code>. Based on these selection i will show a <code>GridView</code> with <code>Check box</code> selection along with some data. This <code>GridView</code> has a header check box through which i can select all check boxes available in <code>gridview</code>. But on selecting this the Radio button selection is also getting changed. Means if i have my <code>Radio1</code> as selected initially and if i click on check box which is available as header the radio button selection is switched to <code>Radio2</code>Why this is happening can any one tell.</p> <p>Script i used for selecting check boxes</p> <pre><code>&lt;script type="text/javascript"&gt; function check_uncheck (Val) { var ValChecked = Val.checked; var ValId =Val.id; var frm = document.forms[0]; // Loop through all elements for (i=0; i&lt;frm.length; i++) { // Look for Header Template's Checkbox if (this!=null) { if (ValId.indexOf ('CheckAll') != -1) { // Check if main checkbox is checked, then select or deselect datagrid checkboxes if(ValChecked) frm.elements[i].checked = true; else frm.elements[i].checked = false; } else if (ValId.indexOf ('checkRec') != -1) { // Check if any of the checkboxes are not checked, and then uncheck top select all checkbox if(frm.elements[i].checked == false) frm.elements[1].checked = false; } } } } &lt;/script&gt; </code></pre> <p>My grid view design</p> <pre><code>&lt;asp:GridView ID="grdPayroll" runat="server" HeaderStyle-BackColor="green" AutoGenerateColumns="False" CssClass="grid_cen" Font-Names="Arial" Font-Size="11pt" AlternatingRowStyle-BackColor="#C2D69B" CellPadding="4" CellSpacing="10" ForeColor="Black" GridLines="Vertical" PageSize="5" Visible="False" BackColor="Black" BorderColor="#d3d4d3" BorderStyle="None" BorderWidth="1px"&gt; &lt;Columns&gt; &lt;asp:TemplateField&gt; &lt;ItemTemplate&gt; &lt;asp:CheckBox ID="checkRec" runat="server" onclick="return check_uncheck (this );" /&gt; &lt;/ItemTemplate&gt; &lt;HeaderTemplate&gt; &lt;asp:CheckBox ID="CheckAll" runat="server" onclick="return check_uncheck (this );" /&gt; &lt;/HeaderTemplate&gt; &lt;/asp:TemplateField&gt; &lt;%--&lt;asp:TemplateField&gt; &lt;ItemTemplate&gt; &lt;asp:RadioButton ID="rdbtnPayroll" runat="server" onclick="RadioCheck(this);" /&gt; &lt;/ItemTemplate&gt; &lt;&lt;&lt;&lt;&lt;&lt;&lt; .mine &lt;/asp:TemplateField&gt;--%&gt; &lt;asp:BoundField DataField="EmpID" HeaderText="Employee ID"&gt; &lt;ItemStyle Width="100px" /&gt; &lt;/asp:BoundField&gt; &lt;asp:BoundField DataField="empname" HeaderText="Employee Name"&gt; &lt;ItemStyle Width="100px" /&gt; &lt;/asp:BoundField&gt; &lt;asp:BoundField DataField="PayPeriodNumber" HeaderText="PayPeriod Number"&gt; &lt;ItemStyle Width="100px" /&gt; &lt;/asp:BoundField&gt; &lt;asp:BoundField DataField="PayRollYear" HeaderText="Payroll Year"&gt; &lt;ItemStyle Width="100px" /&gt; &lt;/asp:BoundField&gt; &lt;asp:BoundField DataField="PaymentDate" HeaderText="Payment Date"&gt; &lt;ItemStyle Width="100px" /&gt; &lt;/asp:BoundField&gt; &lt;/Columns&gt; &lt;HeaderStyle BackColor="#d6dee7" Font-Bold="True" ForeColor="black" Font-Size="smaller" /&gt; &lt;AlternatingRowStyle BackColor="White" /&gt; &lt;EmptyDataTemplate&gt; &lt;h1&gt; No Data Found&lt;/h1&gt; &lt;/EmptyDataTemplate&gt; &lt;RowStyle BackColor="#e7eff7" Font-Size="XX-Small" CssClass="text_center" /&gt; &lt;FooterStyle BackColor="#CCCC99" /&gt; &lt;PagerStyle BackColor="#e7eff7" ForeColor="Black" HorizontalAlign="Right" Font-Size="XX-Small" /&gt; &lt;SelectedRowStyle BackColor="#CE5D5A" Font-Bold="True" ForeColor="White" /&gt; &lt;/asp:GridView&gt; </code></pre> <p>My Radio buttons</p> <pre><code> &lt;asp:RadioButton ID="rdbtnsimulation" Text="Simulation" runat="server" AutoPostBack="True" GroupName="Run" OnCheckedChanged="rdbtnsimulation_CheckedChanged" /&gt; &lt;asp:RadioButton ID="rdbtnlive" Text="live" runat="server" AutoPostBack="True" GroupName="Run" OnCheckedChanged="rdbtnlive_CheckedChanged" /&gt; </code></pre>

Guidance
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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
