Hi guys,
i have two list box(lstRight,lstLeft) in
between these two i have
two
buttons(Moveright,Moveleft) and i added one
requiredfieldvalidator like
<asp:RequiredFieldValidator
id="RequiredFieldValidator1" runat="server" ErrorMessage="Select
atleast one customer"
ControlToValidate="lstLeft"></asp:RequiredFieldValidator>
what i want here is if no items are there
in the left list box then we have to show this
message...
my problem over here is even though item exists in the list
box this RequiredFieldValidator error message will appear... but
if i select any item in the left list box error will
disappear...
is the validator what iam using for this is wrong? even i
tried with customvalidator like this
<asp:customvalidator id="custSelectedCustomer"
runat="server" ErrorMessage="Select atleast one customer"
onServerValidate="CheckCustomer" ControlToValidate="lstLeft"
EnableClientScript="False"></asp:customvalidator>
onServerValidate method will only fire if i try to move
item from left to right not in other case...
can any body help me out.. where exactly iam gng
wrong
Thanks in advance
Vishnu
