I am having some issues with SelectNextControl. Considder the following code:

MessageBox.Show(this.txtValue.SelectNextControl(this.txtValue, true, true, false, false).ToString());

I call this from the this.txtValue.KeyUp and the messagebox always tells me false, i.e. the method failed.

Any clue? (I am sure it is something very simple)

Thanks,
Einar
