gridview enableviewstate

[wimani]

In the gridview (enableviewstate = false), the first column is a boundfield having a DataField = "CallDetailID" and the second column is a checkbox (enableviewstate = false), and there are other columns.

The code-behind for a button on the page goes through all the checkboxes that are selected and retrieves the CallDetailID. When the CallDetailID boundfield visibility is true then I can retrieve the IDs, but when the visibility is set to false the IDs cannot be retrieved.

Is there a setting on the gridview that has to be changed?

Here is some of the aspx and c# code:

<asp:GridView runat="server" ID="gvCallDetails" AutoGenerateColumns="false" OnSorting="gvCallDetails_Sorting" 
                                                        OnRowCommand="gvCallDetails_RowCommand" OnRowDataBound="gvCallDetails_DataBound" BorderStyle="Solid" 
                                                        CssClass="dealgrid" BackColor="white" CellPadding="0" CellSpacing="0" GridLines="None" BorderColor="#4D80D1" 
                                                        BorderWidth="1px" AllowSorting="true" AllowPaging="false"  PageSize="10" EnableViewState="False" DataKeyNames="CallDetailID">
                                                        <RowStyle CssClass="gridbody" />
                                                        <AlternatingRowStyle CssClass="altgridbody" />
                                                        <HeaderStyle HorizontalAlign="Center" CssClass="GridviewFixedHeader" ForeColor="White"  />
                                                        <Columns>
                                                            <asp:BoundField DataField="CallDetailID" Visible="false" ReadOnly="true" />
                                                            <asp:TemplateField>
                                                                <HeaderTemplate>
                                                                    <asp:CheckBox CssClass="cbody" ID="chkHeaderSelect" runat="server" AutoPostBack="true" EnableViewState="false" />
                                                                </HeaderTemplate>
                                                                <ItemTemplate>
                                                                    <asp:CheckBox CssClass="cbody" ID="chkSelected" runat="server" EnableViewState="false" />
                                                                </ItemTemplate>
                                                                <ItemStyle HorizontalAlign="Center"/>
                                                                <HeaderStyle Width="60px" />
                                                            </asp:TemplateField>

                 int iResult;
                 StringBuilder sbCallDetail = new StringBuilder();
                 //GridViewRow row = new GridViewRow();

                 for (int i = 0; i <= gvCallDetails.Rows.Count - 1; i++)
                 {
                     if ((((CheckBox)gvCallDetails.Rows[i].FindControl("chkSelected")).Checked) == true)
                     {
                         sbCallDetail.Append(gvCallDetails.Rows[i].Cells[0].Text + ',');
                     }
                 }

gvCallDetails.Rows.Cells[0].Text doesn't retrieve the CallDetailID for the selected checkboxes unless the visibility of the CallDetailID boundfield is true.

Think it's working now..

Changed:
sbCallDetail.Append(gvCallDetails.Rows.Cells[0].Text + ',');

To:
sbCallDetail.Append(Convert.ToString(gvCallDetails.DataKeys[0]) + ',');

And now I'm able to retrieve the values of CallDetailID
