Can't get button background color to change

[Joanne Ling]

Hi

I have a button of type SfButton, called AutoButton, and I want it to go green when the legend is "AUTO ON".

Here is my code:

        private void AutoButton_MouseClick(object sender, MouseEventArgs e)
        {
            if (AutoButton.Text == "AUTO OFF")
            {
                var confirmResult = MessageBox.Show("Auto Mode selected",
                                     "Please confirm",
                                     MessageBoxButtons.YesNo);
                if (confirmResult == DialogResult.Yes)
                {
                    AutoButton.Text = "AUTO ON";
                    AutoButton.BackColor = Color.Green;
                }
            }
            else
            {
                AutoButton.Text = "AUTO OFF";
                AutoButton.BackColor = Color.Silver;
            }

            AutoButton.Refresh();
        }

The text changes to "AUTO ON", but the button does not go green.

If I use a standard button, it works.  Here is the code for that:

        private void button1_MouseClick(object sender, MouseEventArgs e)
        {
            if (button1.Text == "AUTO OFF")
            {
                var confirmResult = MessageBox.Show("Auto Mode selected",
                                     "Please confirm",
                                     MessageBoxButtons.YesNo);
                if (confirmResult == DialogResult.Yes)
                {
                    button1.Text = "AUTO ON";
                    button1.BackColor = Color.Green;
                }
            }
            else
            {
                button1.Text = "AUTO OFF";
                button1.BackColor = Color.Silver;
            }

            button1.Refresh();
        }

....  why isn't the SfButton changing colour?

Any help would be gratefully received.

Thank you.

Hi Joanne, 

Thank you for your patience. 

 

On further analyzing on the reported behavior, we could found that in SfButton when the control is focused, then the back color will be applied based on the FocusedBackColor property. The background color will be applied if the control is not in a focused state. Hence this reported behavior can be resolved by changing the FocusedBackColor property. 

 

 

sfButton1.Style.FocusedBackColor = Color.Green;
