         <asp:ListItem Value="No" Text="No">No
         
     
     <itemtemplate>
          <asp:Label ID="lblReTot" runat="server" Text='<%# Bind("ReTotal")%>'>
      
<

What I have tried:

C#

RadioButtonList rbl = (RadioButtonList)e.Row.Cells[1].FindControl("rblYesNoPos");
RadioButtonList rblR = (RadioButtonList)e.Row.Cells[1].FindControl("rblYesNoRe");

Try doing FindControl on the Row

(RadioButtonList)e.Row.FindControl("rblYesNoPos");

That depends on where do you want to access it. If you want it at RowDataBound event, then you need to make sure you are checking for the appropriate DataControlRowType first before using FindControl method. For example:

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    //access header template controls
    if (e.Row.RowType == DataControlRowType.Header)
    {
         RadioButtonList rblHeader = (RadioButtonList)e.Row.FindControl("rblYesNoPos");

    }

    //access row template controls
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
         RadioButtonList rblRow = (RadioButtonList)e.Row.FindControl("rblYesNoRe");

    }
}

If want to reference them at Button Click event where your Button is inside the GridView template, then you can do something like this:

C#

protected void Button1_Click(object sender, EventArgs e)
{
        Button b = (Button)sender;
        GridViewRow row = (GridViewRow)b.NamingContainer;
        if (row != null)
        {
            //access header template controls
            if (row.RowType == DataControlRowType.Header)
            {
                      RadioButtonList rblHeader = (RadioButtonList)row.FindControl("rblYesNoPos");

            }

           //access row template controls
           if (row.RowType == DataControlRowType.DataRow)
           {
                     RadioButtonList rblRow = (RadioButtonList)row.FindControl("rblYesNoRe");

           }
      }
}
