Hi.
I have a page with a usercontrol.
In this UC, I have two ListBoxes and two buttons. When i click in one
button, i get the selected item in the listbox.
How can i validate, using validators, if the selected listbox has a selected
item?
Thanks.

RequiredFieldVa lidator does it. If you "unselected " state is actually the
first item shown, set its InitialValue property to the value you assigned to
that "unselected " item.

Thanks Peter.
But how can i do that? I say this because my "unselected " value is a blank
ListItem.
Thanks again.

In true, my listbox doesn't have a "unselected " item.

When there is no selection, the validator will retrieve to a value of ""
from the listbox. Your InitialValue property is already "". So just use the
RequiredFieldVa lidator without changing InitialValue.

Hello All,
I'm trying to get a "Virtual Listbox" to work. I've currently got a form,
and used CreateWindowExA to create a ListBox with the LBS_OWNERDRAWFIXED and
LBS_NODATA flags on it. I've allso subclassed the window and do see all
kinds of WS_??? messages coming by.
But now I'm stuck :-\
I've got *no* idea what to do next, and all my searching on the web leads me

Hi,
I am implemeting a form in asp.net.
The form is quite large and the validation is reasonably complex, so I have
decieded to implement my own validation rather than use any custon
validators,
so I have a button on the form and the "causes validation" property is set
to true.
I have overridden the "Validate()" like so

I have a form that i've split up into multiple asp:panels, each panel
has a number of validators which work correctly.
At on the last panel, i want to commit the data collected to a

through the postbacks, instead of using Sessions, or HttpContext, I
could just take the values from the textboxes.
This all works fine, except for security. I realized that I could

When I put a <asp:ListBox on a web page and populate the data in the page Page_Load event the ViewState for the control is saved and loaded (after postback) correctly.
