Controls.Remove() and Focus

[RedPenn]

Hi,

When I remove a TextBox that has the keyboard focus from a Panel using Controls.Remove, the application seems to have a focus problem and its close button becomes disabled. If I use Add to recreate the Control, without having focus, the app then recovers. It seems like the apps message processing is hanging up somehow.
What can I do to Remove the Control without this problem ?

Thanks,
- Paul.

You could send a tab key to move the focus allong to the next control.

One question, when you are removing the control from tyhe control collection are you removing all of the controls event handlers?

//Remove the buttons click event, use the -= operation
this.button1.Click -= System.EventHandler(this.button1_Click)
//Remove the control any other events and then the control....

Error in code posted in last post I have now tested this and it works fine.

private void button1_Click(object sender, System.EventArgs e)
		{
			this.button1.Click -= new System.EventHandler(this.button1_Click);
			this.Controls.Remove(this.button1);
		}
