Validating event in c

Posted by / 02-Aug-2020 11:04

(and hopefully it will keep working when I add more panels and other controls that may need validation ;-) Regards...I would have though that the lines in the Entering handlers would have been sufficient.Is the setting of Causes Validation on the "other" text box in the Validating handler really necessary?I'm not able to reproduce that behaviour (in an experiment with 3 textboxes).Doesn't it work to simply set Causes Validation to "false" on both text boxes and then set it to "true" for all other controls, and not manipulate it at all in the event handlers?Hi, I have a validating event on a textbox in which I want to prevent the user to leave the textbox without entering the right data. When the text in the txt Code control be more than 5 chars, the messagebox will show only once. Length See this private void txt Code_Validating(object sender, System.

Hello to all I'm handling the Validating event for one text box. If the focus is not on some other control than text box but you try closing the form, this event will be fired twice, since the form performs the validation again.

Cancel=true] to method the message is displayed twice (event fired twice). Thanks I don't know of a way to do this easily, since the validating event happens before then new control gets focus.You can also display a custom error image instead of the default image.
