Hi,

I have a control that inherits from MaskedTexBox and I override OnValidating on it. If validation fails, I'm setting e.Cancel to true within OnValidating in order for the focus to stay on that control, but the focus still leaves the control. What can be an issue here? When debugging, I see, that OnValidating seems to get executed.

Hi,

Maybe you're already aware of that one, but I just wanted to add something related to this OnValidating and setting e.Cancel to true issue. If I set e.Cancel to true inside the OnValidation routine for a control, then all subsequent events are executed not on the control, that appears to have focus on the screen, but actually on that control in which I have set e.Cancel to true! It may be hard to understand this from my explanation, I guess. So, let's say that I have two textboxes: textBox1 and textBox2. I do some validation inside textBox1 OnValidating and set e.Cancel to true there. Then I click inside TextBox2 and this should trigger TextBox2's OnEnter and OnGotFocus routines to be executed, right? But what really gets executed are respective routines in textBox1 still, so in this case textBox1.OnEnter and textBox1.OnGotFocus are executed, although, I clicked inside another control on the form and the focus is in that control on the web form. Hope this helps!
