Force to upper case characters - DOTNET

Add a RegularExpressionValidator to the form and set it's expression to:

^[A-Z]+$

If for some reason the regex validator defaults to caseinsensitive (I've
never tried if it is before now that I think of it) you can use:

^(?-i:[A-Z])$

To force case sensitive mathing

Depending on what is the content of that box, it might be very bad for
international users.

And in fact I would hate such a "feature" as US user.
It forces me to press caps-lock and type in ugly caps text that "screams"
And this is just to save some programmer the trouble of calling one single
API to convert a string to uppercase.

Again, bad internationalization. What about accented characters?
Russian, Greek, etc.?

But if you're talking about some whipment code or a similar thign that will
be printed on some box, it might be unwise to allow greek, chineese etc.
I totally agree that in most situations it would not be a good thing to limit
a user to a very short range of characters, but there are some options I
could think of where it does make sense.

I agree that it would be even better to allow both lower and upper case variants
and just call ToUpper when the user leaves the field.

What was I thinking . I meant a Shipment Code on a parcel.

Why I can't use something like this?

<edititemtemplate>

<asp:TextBox ID="TextBox_str_coast_ref" runat="server" Text='<%#Bind
("str_coast_ref").ToUpper()%>'
</asp:TextBox>

</edititemtemplate>

It gives syntax error !

This is why my answer starts with: "Depending on what is the content of
that box, it might be very bad for international users."
Maybe my English was not clear enough, but that was the idea :-)
