How to prevent a checkbox from showing up in a datagrid with no records?

[Burak]

Hello,

I have a datagrid made up of two columns, the first has a checkbox in
it and the other holds a job id.

<Columns>
<asp:TemplateColumn HeaderText="Select"
HeaderStyle-HorizontalAlign="Center"
ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:CheckBox ID="chkIncomplete" Runat="server"> </asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
<asp:BoundColumn HeaderText="VJC Ref#" SortExpression="JOB_ID"
DataField="JOB_ID" HeaderStyle-HorizontalAlign="Center"
ItemStyle-HorizontalAlign="Center"></asp:BoundColumn>
</columns>

When there are no job ids, I insert a blank row into the grid from
the code behind

row(1) = "No active job orders have been saved"
ds.Tables(0).Rows.InsertAt(row, 0)
dtgActive.DataSource = ds.Tables(0)
dtgActive.DataBind()

when I do this however, the checkbox also shows up.

How can I prevent the checkbox from showing up?

Thank you,

Burak

There are a couple options. One would be to set the checkbox column's
Visible property to False. That is, *before* you call DataBind, do:

dtgActive.Columns(0).Visible = False

When the DataGrid is rendered, it will only have one column. If you
still want the checkbox's column there, but without the checkbox, you'll
need to programmatically reference the checkbox in the TEmplateColumn
and set its Visible property to false. More information on
programmatically referencing Web controls in a TemplateColumn can be
found here:

Happy Programming!
