Text box validating event
Is there anything in WPF I can use to get the same result, an event raised only after the user is It seems that there is no native solution. But when the user click on Enter, he wants the Text Box to validate the change.
So here is my suggestion : use the Lost Focus event and the Key Down event when the key is Enter. It creates lots of problem when you have multiple text boxes on one screen and every text box has some logic written in Validate.
If the form Protected Overrides Sub Wnd Proc(By Ref m As Message) Dim auto Validate Setting As Auto Validate Dim auto Validate Saved As Boolean = False If m.
Super Validator can work with any of these components set or without any of them at all if you are planning to report validation results some other way.
As per my mock up to the left, my best case scenario was to start users in the Text Box control and have them to type in a value and tab to the Combo Box control.
When the Text Box loses its focus the value would be validated and the Combo Box would be populate the appropriate values retrieved from the database.
For example you can require the input for text-box and enforce the format to be an email by assigning Validation1 and Validation2 properties.
Select control you want to assign validation to and change its Validator1 property to choose desired validation type.
I created a custom control that inherits from Text Box.Adding your code to the User Control solved the problem. It saved me a lot of time after I encountered this problem.Like others I'm sure, I tried creating a handler for the form's Closing event and then setting the event's property to false, but it did NOT do the trick. Cancel = Falseyou do this trick for all of the validating control events, then in the Enter Event of the Exit_Button that triggers before the validating event, you set the b Closing Form = true Then it trigger a cascading event and go to the validating event to perform the AND b Form Closing, and will jump to the elsewere you have the e.In previous example you’ve seen required field validator.Super Validator also provides validation based on the Regular Expressions.
