Hello Tanuja,

Check out the following code to achieve the required scenario.
aspx:

 <telerik:GridTemplateColumn UniqueName="TempCol" HeaderText="TempCol" >
     <ItemTemplate>
        <asp:CheckBox ID="CheckBox1"  AutoPostBack="true" runat="server" OnCheckedChanged="CheckBox1_CheckedChanged" />
     </ItemTemplate>
 </telerik:GridTemplateColumn>

cs: (Code to allow only one checkbox checked at a time )

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox sndrChkbx = (CheckBox)sender;
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            if (item.Expanded)
            {
                GridTableView nestedView = (GridTableView)item.ChildItem.NestedTableViews[0];
               foreach (GridDataItem childItem in nestedView.Items)
                {
                    CheckBox chkbx = (CheckBox)childItem["TempCol"].FindControl("CheckBox1");
                    chkbx.Checked = false;
                }
            }
         }
        sndrChkbx.Checked = true;
     }

(code to acess the columns in a row)

 protected void CheckBox2_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox sndrChkbx = (CheckBox)sender;
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            if (item.Expanded)
            {
                GridTableView nestedView = (GridTableView)item.ChildItem.NestedTableViews[0];
                foreach (GridColumn childcolumn in nestedView.Columns)
                {
                    foreach (GridDataItem dataItem in nestedView.Items)
                    {
                        string strtxt = dataItem[childcolumn.UniqueName].Text;
                    }
                }
