how to create a RegularExpressionValidator in runtime ? ?

[Ricardo Corsi P. Cesar]

Hi, i looking for example in asp.net (VB) to make the
RegularExpressionValidator in runtime in my code behind.

I found some similars codes, but nothing in VB..

thanks!

Can you post similar code?

Sure, here we go:

Public Shared Function Test(ByVal campo As TextBox)
Dim rf As New RegularExpressionValidator
rf.ID = "rf"
rf.Enabled = True
rf.Visible = True
rf.Display = ValidatorDisplay.Dynamic
rf.ErrorMessage = "You must enter a value"
rf.Text = "*"
rf.ValidationExpression = "\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"
rf.ControlToValidate = (campo.ID)
rf.EnableClientScript = True
rf.EnableViewState = False
rf.Validate = campo
End Function

but this code above, it seems to do nothing when i use it on a button (on
click event). Something is missing to this simple code work fine.

could you help me up ?

I'm having trouble getting a RegularExpressionValidator to work at all
because I've never needed one, but it looks like you might need to make
this change:

rf.ValidationExpression = "\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"

rf.ValidationExpression = @"\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"

That magical "@" will make the "\" chars in your regexp literal instead of
escape characters.

If you are still having trouble, let me know and I will dig deaper to see
if I can get you a solid example.
