Release R1 2021 SP2

Please refer to the attached project. Pressing A key selects the first tab, B key selected the second tab, etc. The SelectedTab is changed successfully. The content area is refreshed. However, the tab is not visible. The attached gif file illustrates the behavior.

Workaround:

        private void RadTabbedForm1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyData == Keys.A)
            {
                this.radTabbedFormControl1.SelectedTab = radTabbedFormControlTab1;
            }

            if (e.KeyData == Keys.B)
            {
                this.radTabbedFormControl1.SelectedTab = radTabbedFormControlTab2;
            }

            if (e.KeyData == Keys.C)
            {
                this.radTabbedFormControl1.SelectedTab = radTabbedFormControlTab3;
            }


            if (e.KeyData == Keys.D)
            {
                this.radTabbedFormControl1.SelectedTab = radTabbedFormControlTab4;
            }

            //Workaround
            Size s = this.Size;
            this.Opacity = 0;
            this.WindowState = FormWindowState.Maximized;
            this.WindowState = FormWindowState.Normal;

            this.Size = s;
            this.Opacity = 1;
        }

Release R3 2019 SP1

The FulentDarkTheme sets a transparent background which results in a slow resizing. 

Workaround:

this.TabbedFormControl.RootElement.BackColor = Color.Black;
