Question

Hi In my application I haev menu items. one of the menu item name is CLOSE. I also have a textbox in my UI. I want to do soem validation on my textbox on lost focus. I am able to do this but I am not able to handle one case. Scenario is like this: When user type value in textbox and then quickly clicks on CLOSE menu item in that case I don't want my textbox validation to fire. How to achieve this ?

You can do this by two ways: 1) By checking the tab indexes 2) Lost keyboard focus - On LostKeyboardFocus of the TextBox check if the value of property KeyboardFocusChangedEventArgs.NewFocus is equal to CLOSE. void TextBox_LostKeyboardFocus ( object sender KeyboardFocusChangedEventArgs e ) { if ( e . NewFocus == CLOSE ) { //do not validate } //validate textbox value }
