Visual basic textbox validating event
Hope this helps Jay "norton" Hi All, I am writing a simple win form which contains a button, when user click the button i want to validate all the other textbox and see if there is anything goes wrong may i know how can i trigger the validating event for all text box?
However you can in my opinion for ever do (not tested) sub Button Click event textbox1_validating(textbox1,nothing) textbox2_validating(textbox2,nothing) etc.In this lesson we demonstrate how events are utilized in the .NET Framework Class Library specific to WPF and ASP. In these examples, we see how C# is generated by the IDE to "wire up" a user action or application event to the code that handles that event. NET works with events and how events drive most Graphical User Interface based applications.Hi Eric There was a good sollution in this newsgroup from Jeffrey Tan, Someone cleaned it up.There stayed another sollution from Jeffrey, describes the problem good, but gives not such a nice sollution.The Behavior mechanism extends the capabilities of visual controls and adheres to the MVVM pattern. To use a Behavior, place it in this collection in XAML.
You can implement missing functionality with a custom Behavior and begin using it any place in your application without code-behind and duplicated code.
end sub As alternative for the already supplied options, while not knowing what actions you take because of validationg errors.
Is there a way to cancel the validating event on the closing event?
