Hi Niclas,
If your checkbox is built inside the .aspx file, you can check the checkbox
for all non-null values like this:
<asp:DataGrid id="DataGrid1" runat="server">
<Columns>
<asp:TemplateCo lumn HeaderText="Cur rency Value">
<ItemTemplate >
<asp:CheckBox id="CheckBox1" runat="server" Checked='<%# not
isDBnull(DataBi nder.Eval(Conta iner, "DataItem.Curre ncyValue"))
%>'></asp:CheckBox>
</ItemTemplate>
</asp:TemplateCol umn>
</Columns>
</asp:DataGrid>
The same thing in the code behind would be like this:
oCheckBox.Check ed = Not IsDBNull(contai ner.DataItem("C urrencyValue"))
Is that what you meant?

Hi,
I have managed to create a Datagrid with a template column with checkboxes
following Q306227. The dataset i have bound to the datagrid contains 1
column that allows NULL value and I would like to bind the checkbox to be
checked if this value is anything else than DBNULL. I have used to
designer
to create the grid and dataset etc, and from what I understand I need to
edit the databinding property of the checkbox in the template to evaluate
the Checked property, but I have not managed to figure out how to create
an
expression that evaluates if a coulmn is empty or not.
Any hint would be appreciated
Regards
Niclas
