I have a ListBox server control named "lb_dates" with a SelectionMode of
"Multiple". The user can select multiple dates from the listbox.
I have ObjectDataSource named "ods_rfq" with a ControlParameter that has a
ControlID that points to "lb_dates". The PropertyName of the ControlParameter
is "SelectedValue".
The user selects two dates from the ListBox.
I am trying to pass BOTH selected values of the ListBox to a SelectMethod of
the ObjectDataSource.
For some reason, all I get passed to the SelectMethod is one of the two
values that the user selected in the ListBox?
In the SelectMethod, I have tried to define the parameter as both a String
and a ListBox but it appears that the ListBox values are being passed as a
string.
I have searched the Internet on this topic and didn't find a true answer.
Some guy hid the ListBox values in a Label field, then accessed that. I guess
I can do that but I would rather find a better solution, if there is one.
Could someone enlighten me as to how I can access both (or all) of the
selected items in the ListBox, rather than just one of them?
The code is below for reference.
