RESOLVED!! How to display a checkbox in a Datagrid?

How do you make a boolean column appear as a checkbox in a datagrid using VB code behind the pages?

My original code looks like this (generated when I was designing my datagrid using the property pages):

Code:

---

<asp:BoundColumn DataField="ItemMarkDown" HeaderText="Markdown">
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:BoundColumn>

---

I then went to my HTML code and replaced it with this:

Code:

---

<asp:TemplateColumn HeaderText="MarkDown">
        <ItemTemplate>
        <asp:CheckBox id="ItemMarkDown" runat="server" checked='<%# DataBinder.Eval
                (Container.Dataitem, "ItemMarkDown")%>' Enabled=False />
        </ItemTemplate>
</asp:TemplateColumn>

---

I run the page (F5) and it correctly displays the boolean field with a checkbox. However, when I try to click back to "DESIGN" tab, I get an error:

Quote:

---

Could not open in Design view. Place quotes around a '<% %>' block used as an attribute value or within a <Select> element.

---

I tried placing quotes but that didn't work.

Is there a way to do this on the vb code page instead of the html page?

Any ideas?

Thanks

I've been working and "researching" on this problem since this morning. Guess what? I rebooted my PC and then it worked with no problems.

Really weird (and frustrating)!!
