Button highlighting on tabstop

John Luciani

Hi,
I am designing a c# program in Visual Studio. This program is a fitness tracker for persons with disabilities, specifically Down Syndrome. All of the buttons within the program are accessed by means of a simplified keyboard consisting of the arrow buttons, tab button, and enter.
What I am looking to do is make it so that when you arrow over to a specific button, it will change color so that the user can tell exactly where they are within the program or rows of buttons. I do not have the option to use a mouse but have seen the feature for mouseover which allows one to do what I am looking to do.
The simplest solution would be better as we have a delivery date for this project of May 7th.
Thanks kindly,
John

An easy way to add an eventhandler is to go to the Properties Box for the Button, click on the 'lightening bolt' symbol to list its events and then double click on the ones you're interested in.

This will open up skeleton eventhandlers to which you can add your code.

However, you won't find the GotFocus and LostFocus events listed as it's recommended in the MSDN docs that you use the Enter and Leave events instead.

So. I'd do this for the first button and then add this code;

private void button1_Enter(object sender, System.EventArgs e)
{
Button b = (Button)sender;
b.ForeColor = Color.Red;
}

private void button1_Leave(object sender, System.EventArgs e)
{

Button b = (Button)sender;
b.ForeColor = Color.Black;
}

You can then use these same eventhandlers for other buttons as well by selecting them from the dropdown list for these events rather than double clicking them to create a new eventhandler.

Another possibility is to handle the event of getting and losing focus. Also you could change the image instead of just changing the color.

I think I figured out part of the problem. The code listed above is actually VB code. I am using C#. Is there any way to add this color definition to an already implemented event? I am a newb and am unsure of how to implement this new event handling as it relates to the button itself.

You can use Focus Event Lost FOcus and GotFocus to Change Color

try this Code

    Private Sub Button1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.GotFocus
        Button1.ForeColor = Color.Red
    End Sub

    Private Sub Button1_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.LostFocus
        Button1.ForeColor = Color.Black
    End Sub
