Could not open in design view!!

I had my project working last night. When I tried to open it this morning, it wouldn't show me design for one of the pages. Complains something like this:

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

Here is my HTML and script page:

<%@Register tagprefix="FSA" TagName="NavigationBar2" src="NavigationBar2.ascx" %>
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="frmLMCAssignments.aspx.vb" Inherits="FSA_1._1.frmLMCAssignments" debug="true"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
.
.
<body
<form
<table
<tr
<td
<asp:datagrid
<columns>
<asp:TemplateColumn HeaderText = "Assigned">
<ItemTemplate>
    <asp:CheckBox ID = "cbAssigned" Runat = "server"
        Checked = <%#DataBinder.Eval(Container.DataItem,"IsAssigned" )%>
    Enabled = False />
    </ItemTemplate>
    </asp:TemplateColumn>
/td>
/tr>
/table>
/form>
/body>

These are the only places where I'm using '<% %>' blocks.

Will appreciate any help.

Do you have a <SELECT> element...?

Try this...

Code:

<asp:CheckBox ID = "cbAssigned" Runat = "server"
        Checked="<%#DataBinder.Eval(Container.DataItem,"IsAssigned")%>"
        Enabled="False" />

I would advise to always put attributes in quotes.

Note regarding this: I think that when you do something like put a Databinder result in a web control attribute value you have to put it in single quotes...

Code:

<asp:CheckBox ID = "cbAssigned" Runat = "server"
        Checked='<%#DataBinder.Eval(Container.DataItem,"IsAssigned")%>'
        Enabled="False" />

Kind of weird but that is what seems to work.

Thanks planoie, you hit it on the dot.

Yes, this allows you to see your page in design view, but the resulting HTML checked='true' or checked='false' (with single quotes) does not do what you'd expect in a browser: For example, in my IE 6.0, if all radio buttons are checked='false' the very last one will appear checked. :) IE expects there to be the word checked (without quotations) or not... I don't know how to solve this issue: you can't seem to be able to open the aspx page in design view and have it behave correctly in browser too :).
