Two options: Use a NumericUpDown instead. NumericUpDown does the filtering for you, which is nice. Of course it also gives your users the ability to hit the up and down arrows on the keyboard to increment and decrement the current value. Handle the appropriate keyboard events to prevent anything but numeric input. I’ve had success … Read more
As per Prerak K’s update comment (since deleted): I guess I have not presented the question properly. Situation is this: I want to load data into a global variable based on the value of a control. I don’t want to change the value of a control from the child thread. I’m not going to do … Read more
