Problem:
Resolution:
Yes, this can be done by using the Focus method of the Control class. There is an example program attached to this article. The description of this program is as follows:
TESTFOCUS
This example program demonstrates how to explicitly set focus to a specific control on a form depending on some contition in the program by using the Focus method of the control class.
This form has on it three TextBox controls and a radiobutton group.
The focus will be set to one of the three TextBox controls depending on which radio button is selected.
The CheckChanged event is fired on a radio button whenever that state of the button is changed, on to off or off to on.
This is why we must use the Checked property to determine if the radio button was actually selected.
