Web Forms :: Textbox Validation Code Doesn't Run When Textboxes Are Empty?
Jan 13, 2011I want the validation condition to be: on a pair of textboxes, to be valid as long as at least one of them isn't empty.
So I put a customvalidator on the 2nd textbox, hooked up to the following server code and client code:
<script type="text/javascript">
function ECPhoneOrEmailRequired(source, args) {
var ecPhone = document.getElementById("txtEmergencyPhone");
var ecEmail = document.getElementById("txtEmergencyEmail");
if (ecPhone.value.length < 1 && ecEmail.value.length < 1) {
args.IsValid = false;
}
else {
args.IsValid = true
}
}
</script>
Protected Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs)
'args.IsValid
If (txtEmergencyPhone.Text = String.Empty And txtEmergencyEmail.Text = String.Empty) Then
args.IsValid = False
Else
args.IsValid = True
End If
End Sub
From what I can tell thru breakpoints, this code works fine as long as there's something in one of the two textboxes. When both textboxes are empty, the code is never called - and so both boxes empty ends up being allowed.
So what's the correct way to validate one-or-the-other-nonempty condition?

Web Forms :: Regular Expression For Empty Textbox?

View 1 RepliesWeb Forms :: Regular Expression For Empty TextBox
Nov 20, 2010I am using regex for server side validations.
I am facing a problem with regex. I want to check for sepecial characters like ><*&()%$@!~+...
I need to filter these special charecters...but the problem is in my 10 textboxes there only 3 are required...
I can submit the form without entering anything...but my regex is not allowing me to submit the form without giving a space from keyboard...
I just want to check for special charecters and empty textbox without giving a spacebar...
I just check these sites(http://regexlib.com/ and http://www.regular-expressions.info/) and read some documentation on regex...its kind of confusing....
Here is my regex for Middlename: ^[a-zA-Z''-'s]|[ ]{1,40}$ its worked but its not correct....then I changed it to ^[a-zA-Z''-'sd*]{1,40}$ this also not taking emptytextbox without giving a space...
My Goal:
In most of the textboxes I need to allow only numbers and - # _ in some textboxes....
For Address: need to allow alphabets and numbers and #-_' "
City: numbers and alphabets no special chars...
Main problem is I can write regex for most of these stuff but need to all textboxes without entering anything (empty textboxes).My work got stoped due to this.

Web Forms :: Saving Empty Textbox To SQL Table?
Sep 9, 2010I have a textbox named txtOrderDate on my web page. I have a VB.net subroutine that saves various textboxes from my web page to my SQL table using a stored procedure. If a valid date is entered into txtDate, then my save works correctly. I have a column named OrderDate in my table. This is the column I am saving txtOrderDate to. OrderDate is defined as a date column and null is allowed.
But if txtorderDate is blank, my subroutine bombs saying cannot convert string to date. I tried various things like making the value of txtDate = DBNull.value if blank but nothing works. Seems like there would be an easy way to do this.
