Can anyone help me to get the value of the CheckBox from the nested grid?

I have the grid inside the grid, in the child grid I have a CheckBox. I am trying to get the value of the CheckBox to insert it into the database, but I am not getting the value.

Please help me to get the value.

ASP.NET

<asp:GridView ID="HeaderCheckGv" runat="server" AutoGenerateColumns="False" OnRowDataBound="HeaderCheckGv_RowDataBound">
                    <columns>
                        <asp:BoundField DataField="POLICY_MAIN_ID" />
                        <asp:BoundField DataField="POLICY_ID"  />
                        <asp:BoundField DataField="POLICY_VALUE"  />
                        <asp:TemplateField >
                            <itemtemplate>
                                <asp:Label ID="GroupNameLbl" runat="server" Text='<%# Eval("POLICY_NAME")%>'>
                                <asp:GridView ID="ChildCheckGv" runat="server" AutoGenerateColumns="False" OnRowDataBound="ChildCheckGv_RowDataBound">
                                    <columns>
                                        <asp:BoundField DataField="POLICY_MAIN_ID"  />
                                        <asp:BoundField DataField="POLICY_ID" />
                                        <asp:BoundField DataField="POLICY_NAME" />
                                        <asp:TemplateField HeaderText="GeneralPolicy">
                                        <itemtemplate>
                                                <asp:CheckBox ID="GeneralPolicyCb" runat="server" />
</itemtemplate>
                                    </columns>
                            </itemtemplate>
                    </columns>
                </columns></itemtemplate></columns>

try this:-

private void HeaderCheckGv_RowDataBound(object sender,
  GridViewRowEventArgs e)
{
  if(e.Row.RowType == DataControlRowType.DataRow)
  {
    //Finding the Grid Control First
    GridView grdChildGrid=(GridView)e.Row.FindControl("ChildCheckGv");
    
   //From the object of founded Child Grid Control we can easily get the controls  value in the child grid like this
     CheckBox chkBox=(CheckBox)grdChildGrid.Row.FindControl("ChildCheckGv");
     bool chkValue = Convert.ToBoolean(chkBox.Value);
  }
}

I hope this will help you out. Please don't forget to mark this as your answer :)
