The server tag is not well formed

[Guest]

I am using an <asp:Repeater> control to generate some checkboxes (C# /
ASP.NET 2.0). The following code works fine:

============================================
<input type="checkbox" name="worksOk" value='<%#
Eval("StoredProcedureID") %>' <%#
isChecked(Eval("StoredProcedureID").ToString()) ? "checked" : "" %> >
============================================


However, when I add [runat="server"] to the <input> tag, an error
message is generated when I try to compile my page ("The server tag is
not well formed"):

============================================
<input runat="server" type="checkbox" name="doesNotWork" value='<%#
Eval("StoredProcedureID") %>' <%#
isChecked(Eval("StoredProcedureID").ToString()) ? "checked" : "" %> >
============================================


Is there any logical explanation for why this happens?

Just curious - why are you not using a CheckBox control (one of the ASP.NEt
built in web controls)?

 

[Guest]

Because Microsoft saw fit to remove the Value property of the
<asp:Checkbox> control. You can read more about this at
http://tinyurl.com/uuy47 -- I spent three days trying to format a
collection of checkboxes inside an HTML. And in the end, the solution
was to do exactly what I've been doing with Classic ASP for the past
eight years: get posted-back values from the Request object and then
use in-line preprocessor directives (<%# ... %>) to ensure that the
checkboxes are re-checked.

the html controls do not support binding. you are tryng to set a string
binding expression to a bool value.

If HTML server controls do not support binding, then how does the
solution MikeS proposed ( http://tinyurl.com/uuy47, post # 6 ) work?

Also, I'm a bit confused what you mean when you say I'm trying "to set
a string binding expression to a bool value" -- what bool value are you
referring to? The isChecked() function returns a boolean value, which
is then used to determine what string is written to the client
("CHECKED" or empty string) by uing the C# ternary operator (
http://www.kdkeys.net/blogs/tgrts_blog/archive/2005/04/19/4576.aspx ).
Or am I missing something

Yes, but the 'Checked' property IS there, with the ASP.Net Checkbox, and
therefore works just fine in its place.

 

[Guest]

Let's consider the example that I posted about (
http://tinyurl.com/uuy47 ). I have a form that lists all user-defined
stored procedures in a SQL Server database. Each stored procedure has
its name displayed to the right of its corresponding checkbox -- the
list is formatted using an HTML table. By "checking off " one or more
checkboxes, the database object IDs that correspond to my selections
are made available via Request.Form upon postback.

How would I transmit the object ID behind each checkbox using the
<asp:CheckBox> control, if it has no Value property? Without those
IDs, the Checked property is meaningless. And as far as
<asp:CheckBoxList> is concerned -- wouldn't I be sacrificing how my
checkboxes are laid out in HTML by using it?

Hmm - I have to say I'm struggling to see the problem here...

Is this the sort of functionality you're looking for:

Which problem -- the one I originally posted about, or what I'm trying
to accomplish?

Mark --

Yes, that's what I'm trying to do, but without having to rely on having
ViewState enabled. There's more to it -- for example, each row also
has a collapsible DIV tag that allows you to see the stored procedure's
CREATE PROCEDURE statement -- which is why I'm wary of using server
controls, like <asp:CheckBoxList>, that don't afford a lot of
flexibility in how my HTML is laid out.

OK - good luck, then...

Oh I don't know - one of them, maybe...
