Hi all,
I am working on my first web application and now I have run in to a problem with a custom validator I am trying to use. The thing is that I have to check three input fields against a database table to decide if this is a unique combination that can be inserted or if it already exists. I think I understand how to write the validator on the form page and I know how to connect to the database to check the table. The problem right now is that I can't get hold of the fields to validate in my function. Probably easy to solve but like I said...I'm a noob ;)
My custom validator:
<asp:CustomValidator ID="CustValUniqueKeyNbr" runat="server"
Display="Dynamic" OnServerValidate="CustValUniqueKeyNbr_ServerValidate"
ErrorMessage="There is already an active entry with this number and keyword"></asp:CustomValidator>
On the code page:
Protected Sub CustValUniqueKeyNbr_ServerValidate(ByVal sender As Object, ByVal args As ServerValidateEventArgs)
'Here I would like to get the values from the textboxes
Dim num As String = NumTextBox.Value
Dim key As String = KeyTextBox.Value
Dim todate As Date = ToDateTextBox.Value
'Connect to database and check input
Any help would be greatly appreciated!
