asp.net datagrid control:

Hi Clear (real names are considered more polite)

You just need to set the checked value to the boolean. Here's the idea, full
code below.

<asp:templatecolumn headertext="Boolean">
<itemtemplate>
<asp:checkbox id="CheckBox1" runat="server"
checked='<%# DataBinder.Eval(Container, "DataItem.Boolean") %>' />
<br />
</itemtemplate>

Let us know if this helps?
