Validators (which is a collection of IValidators) to Base Validator in order to retrieve its validation group and all controls implementing directly the IValidation without subclassing Base Validator class are skipped.If instead the button does not have any validation group set everything works perfectly.Generally, this method returns the same result as to Lower Case() method.However, for some locales, where language conflicts with the regular, Unicode case mappings occurs (such as Turkish), the results may vary. After creating an empty project, create an empty controller under controller folder by right clicking controller folder. After the creation of Controller, right click Action method and click Add view to create View (the action method name will be an index).Now, run the Application and leave textbox as empty and click Validate button. Here, we may use both to Lower Case and to Locale Lower Case to convert the text to lowercase.

I do use this on the Text Changed event, because I don't want the user to continue typing if it's an invalid character; the rule checking "eats" the invalid character. Valid = True End If Else Select Case m Check Type Case Check String If m Input Mask. Valid = True End If Case Else '// right now we're only testing for numbers...

Valid = False Else If m Check Type = Check Byte And CType(Me. Text, Integer) Dim err Provider As New Error Provider ' Verify that this field is not blank.
Text Box1, "This field does not accept negative values.") Me.
I have an Text Box control on my page and a search button whenever user clicks on the search button i want to validate the Text Box for Blank.
