Hi

I have datagrid with 8 items. Out of which 2 items are checkboxes. Data is
binded dynamically to the datagrid

Based on some values from the database I have to check or uncheck the
checkbox in the datatgrid.

Does any one know how to do this?

Thx

You can use an IIF statement in the ItemTemplate like this when you get the
value from the database:

Checked='<%# IIF(DataBinder.Eval(Container,
"DataItem.Boolean"),"true","false") %>'

Or, if the database already has a boolean, you ca do this:

Checked='<%# DataBinder.Eval(Container, "DataItem.Boolean") %>'

More code below.

Does this help?

<asp:TemplateColumn HeaderText="Boolean Value">
<ItemTemplate>
<asp:CheckBox id=match runat="server" onCheckedChanged="updateStatus"
Checked='<%# DataBinder.Eval(Container, "DataItem.Boolean") %>'
AutoPostBack="True">
</asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn HeaderText="Boolean Value">
<ItemTemplate>
<asp:CheckBox id="Checkbox1" runat="server"
onCheckedChanged="updateStatus" Checked='<%# IIF(DataBinder.Eval(Container,
"DataItem.Boolean"),"true","false") %>' AutoPostBack="True">
</asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
