Web Forms :: How To Perform Validation For A Textbox Based On Other Textbox
Jan 28, 2011I'm using 3 text boxes for allowing user selecting different ranges. I want to perform below validations on three text boxes.
1.User should enter a value (i.e. a valid number,doesn't allow to enter zero,decimal numbers and negative numbers) in 1st text box.
2. 2nd text box value should be greater than 1st text box.
3. 3rd text box value should be greater than 2nd text box.

View 1 RepliesVS 2015 - Enable Textbox After Validation Of Prior Textbox
Mar 8, 2016I have TextBox1 (enabled = true) and TextBox2 (enabled = false) in my WebForm on loading. Both are validated by means of a RegularExpressionValidator.
How can I set TextBox2 enabled = true ONLY AFTER (!) the text inserted in TextBox1 has been validated and accepted as valid ?
Can this be done on client side exclusively or is some code behind absolutely necessary ?

Web Forms :: Mulitiple Validation Of A Textbox?
Nov 29, 2010I have a project due for my Visual Basic course. The project is creating a web application. I'm setting up the application where the user will enter information in a textbox. I want to be able to test the value entered in the textbox. There are three test conditions - less than a certain number, between a range of numbers, and greater than a certain number. I'm familiar with Visual Basic but not that with Visual Web Developer. I want to display a message to the user that tells them the value entered is low, normal, or high, and display additional information. The question I have is can I attach three validation controls to a single textbox? I know how to attach one validator control, and that works fine. I try to attach three controls but when I run the program all three error messages display, which is not what I want. I think I would need to code a custom validator but not sure how to do that.

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?
