C#-FORM Way to reference textbox that holds cursor?

[ntabb]

I'm writing a function to cut the information out of a textbox when a button is pressed. There are many textboxes on the form, and I only want to cut the information in the box that has the cursor. I really don't want to look for the cursor in each textbox in each level of the form.

Is there a way to reference the "current" textbox?

Thanks,
NT

Well, when you click a button, the cursor LEAVES the textbox it was in, making NO textbox the current textbox. So you might want to re-think how you do that.

Possibly using the onFocus() and onBlur() events in javascript?

Good point. I'm looking into the onFocus now....

Maybe keep a tracking variable. At each TextBox Focus Enter event update the tracking variable to the new TextBox control. Then when you hit the magic key, even if you leave the TextBox in question you will still know which control last held the focus.

All the TextBoxes can go to the same event handler with something like
Control myTracker = (Control)sender ;
