Validating text box when OK button is pressed

Cameron

Hey All I'm just starting to look at textBox validation by creating an InputBox form which the user can enter a string into a text box and then click either OK or Cancel (which have the DialogueResult set to = OK and Cancel). There is an event that occurs when the textBox is validating in which I check if the textBox contains a string or not. Currently when I click either the OK or Cancel buttons the check is performed, however I want to only perform it when the OK button is clicked. Is there anyway of determine what caused the validating event? Or any ideas how I can only perform the check when the OK button is clicked? I could have an event occur when the button is pressed that checks the textBox, but thought I would give the textBox validating method a go. Any ideas would be greatly appreciated! Cameron

Thank you! I used method one and that worked fine.

1.You can validate you text data when FormClosing event raises. It will be after you have pressed OK or Cancel button. The dialog result will be already set.
2. Move the checking of data from Validated event - to Ok click event handler. Leave the Cancel click unhanled.

Problem is : the "text box validated" raises when the textbox lost focus. In this time it is unknown, wich control will get focus - button Ok, button Cancel or other text box...
