Question

Let’s say I have internet explorer embedded in a windows form and I then navigate to a random page on the web. How can I determine when a textbox (or any other control that can accept text input for that matter) becomes the item in focus? Basically, every time the mouse is clicked I can check to see if the item in focus is a textbox or some other control for text input and then act appropriately.

Thanks in advance,

Bob

You still haven’t explained the roll of the WebBrowser but the problem seems to be tracking the Input Focus. I don’t know of a Form level event but you can hook an eventhandler to the Enter or GotFocus event of all relevant Controls.

// in Form_Load foreach (var control in this.Controls)  control.Enter += OnEnterControl;   private void OnEnterControl(object sender, EventArgs e) {   focusControl = (sender as Control); }
