Gridview RadioButton Column Single Select

In the gridview radiobutton column, if we need to select a single radio button as a single option then we need to do some javascript for that...

JavaScript for single select radio button:

<script type="text/javascript">
function RadioChecked(param)
{   
var frm = document.forms[0];              
for (i=0; i < frm.length; i++)  
    {      
    if (frm.elements[i].type == "radio")      
        {     
            if (param != frm.elements[i].id )     
            {        
                frm.elements[i].checked = false;     
            }      
        }  
    }
}

</script>

Code behind:

  protected void YourGridView_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowIndex != -1 && e.Row.DataItem != null)
        {
            //calling javascript function to restrict the user to select only one radiobutton
            RadioButton rd = (RadioButton)e.Row.FindControl("rdbGVRow");
            rd.Attributes.Add("onclick", "javascript:RadioChecked('" + rd.ClientID + "');");
        }

   }
