[Solved] When accessing a hidden column, it makes it visible

[Clarence Klopfstein]

I have a grid with many columns in it.  I made several columns 'ReadOnly' and 'Display='false''.  When I accesss one of those columns in code behind it then shows up when the grid is refreshed, though with no real data, just this: "System.Data.DataRowView"

Here is the code that matters:

<telerik:GridTemplateColumn UniqueName="SetPrice" Display="false" HeaderText="SetPrice" HeaderStyle-Width="0px" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" ReadOnly="false">
                        <ItemTemplate>
                            <asp:Label ID="lblSetPrice" runat="server" Text='<%# Eval("SetPrice") %>'></asp:Label>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>

AND:

        private void SetTotalAmount()
        {
            double total = 0;
            foreach (GridDataItem item in grdContractItems.Items)
            {
                Label lblMetalValue = (Label)item.FindControl("lblExPrice") as Label;
                Label lblLabor = (Label)item.FindControl("lblExPrice") as Label;
                Label lblPrice = (Label)item.FindControl("lblExPrice") as Label;
                Label lblExPrice = (Label)item.FindControl("lblExPrice") as Label;
                Label lblSetPrice = (Label)item.FindControl("lblSetPrice") as Label;
                if (lblSetPrice.Text != "0")
                {
                    lblMetalValue.Text = lblLabor.Text = lblPrice.Text = "";
                    lblExPrice.Text = lblSetPrice.Text;
                }
                if (lblExPrice != null && lblExPrice.Text.Trim() != string.Empty)
                {
                    total += double.Parse(lblExPrice.Text);
                }
            }
            lblTotalAmount.Text = GetDollar(total.ToString());
        }

Hi Clarence,

I have prepared a simple sample implementing a similar functionality which works as expected on my end. Take a look at it and let me know how to modify it in order to reproduce the problem.
