All of these key press do result in the Preview Key Down event being fired.
This means that to do complete validation of all changes to a Text Box, you’ll likely want to do some validation in Preview Text Input and some additional validation in Preview Key Down.
For years I've been living with the unsettling feeling that there's something mysteriously wrong with ASP. Every time I made the courageous decision to tackle this elusive control and try to harness it for my use, something would go wrong.
There are two ways to manage unwanted execution of event handlers. Data Grid View Cell Validating Event Args' does not contain a constructor that takes '1' arguments" what is the solution for this???????
Something there is causing the cell validating event to fire. [Edit] The validating event is firing because focus is being moved from the DGV to the button.
Hi, Looking at the code for setting up form controls in it appears we detect control changes on Change "register On Change" eg.
if a user types into an input control that is an ng2 angular control, each keypress triggers a validationcheck ..
It appears to be a big change if i were to change it from On Change to something like Lost Focus of the control ...
