Release R1 2023

Steps to reproduce:

1. Press the left mouse button inside RadToggleSwitch. (MouseDown)

2. Move the mouse 1 px up or down (but still inside the RadToggleSwitch). (MouseMove)

3. If you release the left mouse button now, the switch will not toggle. (MouseUp)

Only if the mouse location at the moment of Press and Release are exactly the same, the toggle action will be triggered.

RadToggleSwitch can be activated and the slider can be dragged by using the right mouse button as well. That's not supposed to happen.

Just like in the case of RadCheckBox, RadToggleButton has a few states. Therefore, we need to add the possibility in Visual Style Builder to style the RadToggleButton when it is disabled and taking into consideration the toggle state (on/off)

FIX. RadButton does not indicate that it is pressed when it is clicked with key instead of clicking with mouse

Release R3 2019 (LIB 2019.2.729)
I have RadDiagram on Form and registered ShapeDoubleClicked event on it.

After double click on a shape I open another modal form (let's call it form2). The second mouse click is fired on a modal form (Form2) which in some cases, based on shape position in Form1 (precisely when the shape is in center of the screen), change the state of my ToogleSwitch which is in center of Form2.

When you customize a theme for RadSplitButton, you are not able to change the color of the action button element when it is pressed and the drop down is not opened. 

Workaround:
this.radSplitButtonElement2.ActionButton.MouseDown+=ActionButton_MouseDown;
this.radSplitButtonElement2.ActionButton.MouseUp+=ActionButton_MouseUp;

private void ActionButton_MouseUp(object sender, MouseEventArgs e)
{
    this.radSplitButtonElement2.ActionButton.ButtonFillElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
    this.radSplitButtonElement2.ActionButton.ButtonFillElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
}

private void ActionButton_MouseDown(object sender, MouseEventArgs e)
{
    this.radSplitButtonElement2.ActionButton.ButtonFillElement.BackColor = Color.Red;
    this.radSplitButtonElement2.ActionButton.ButtonFillElement.GradientStyle = GradientStyles.Solid;
}

The same case is valid for RadToggleButton as well.

To reproduce: use the following custom RadCheckBox. You will notice that the ToggleStateChanging, ToggleStateChanged, PropertyChanged, CheckStateChanging, CheckStateChanged won't fire anymore:

public class MyCheckBoxElement : RadCheckBoxElement
{
    protected override Type ThemeEffectiveType
    {
        get
        {
            return typeof(RadCheckBoxElement);
        }
    }
}

public class MyCheckBox : RadCheckBox
{
    protected override RadButtonElement CreateButtonElement()
    {
        return new MyCheckBoxElement();
    }

    public override string ThemeClassName
    {
        get
        {
            return typeof(RadCheckBox).FullName;
        }
    }
}

Workaround:

public class MyCheckBoxElement : RadCheckBoxElement
{
    protected override void OnKeyDown(KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            return;
        }

        base.OnKeyDown(e);
    }

    protected override Type ThemeEffectiveType
    {
        get
        {
            return typeof(RadCheckBoxElement);
        }
    }
}

public class MyCheckBox : RadCheckBox
{
    protected override RadButtonElement CreateButtonElement()
    {
        MyCheckBoxElement checkBox = new MyCheckBoxElement();
        checkBox.ToggleStateChanging += new StateChangingEventHandler(ButtonElement_ToggleStateChanging);
        checkBox.ToggleStateChanged += new StateChangedEventHandler(ButtonElement_ToggleStateChanged);
        checkBox.PropertyChanged += new PropertyChangedEventHandler(res_PropertyChanged);
        checkBox.CheckStateChanging += new CheckStateChangingEventHandler(res_CheckStateChanging);
        checkBox.CheckStateChanged += new EventHandler(res_CheckStateChanged);
        return checkBox;
    }

    private void res_CheckStateChanged(object sender, EventArgs e)
    {
        base.OnCheckStateChanged(e);
    }

    private void res_CheckStateChanging(object sender, CheckStateChangingEventArgs args)
    {
        base.OnCheckStateChanging(args);
    }

    private void res_PropertyChanged(object sender, PropertyChangedEventArgs e)
    {
        if (e.PropertyName == "IsChecked")
        {
            base.OnNotifyPropertyChanged("IsChecked");
        }
    }

    private void ButtonElement_ToggleStateChanged(object sender, StateChangedEventArgs args)
    {
        base.OnToggleStateChanged(args);
        base.OnNotifyPropertyChanged("Checked");
        base.OnNotifyPropertyChanged("CheckState");
        base.OnNotifyPropertyChanged("ToggleState");
    }

    private void ButtonElement_ToggleStateChanging(object sender, StateChangingEventArgs args)
    {
        base.OnToggleStateChanging(args);
    }

    public override string ThemeClassName
    {
        get
        {
            return typeof(RadCheckBox).FullName;
        }

To reproduce: apply the Window8 theme to the entire application containing a RadButton and a RadCheckBox. Change the color of RadButton to Green and handle the RadCheckBox.ToggleStateChanged event in order to enable/disable the button. You will notice that after disabling once the button enabling it again, the ButtonFillElement.NumberOfColors property is set to 1 and gradient color becomes solid. Please refer to the attached sample project and gif file.

Workaround:

int numberOfColors = 0;

private void radCheckBox1_ToggleStateChanged(object sender, Telerik.WinControls.UI.StateChangedEventArgs args)
{
    if (args.ToggleState == Telerik.WinControls.Enumerations.ToggleState.On)
    {
        this.radButton1.Enabled = true;
        this.radButton1.ButtonElement.ButtonFillElement.NumberOfColors = numberOfColors;
    }
    else
    {
        numberOfColors = this.radButton1.ButtonElement.ButtonFillElement.NumberOfColors;
        this.radButton1.Enabled = false;
    }
}

Parse event of the property binding is not fired when you change the ToggleState value of RadToggleButton:

Workaround:

private void Form1_Shown(object sender, EventArgs e)
		{
            Binding b = new Binding("ToggleState", vm, "IsToggleSet", true, DataSourceUpdateMode.OnPropertyChanged);
			b.Format += new ConvertEventHandler(b_Format);
			b.Parse += new ConvertEventHandler(b_Parse);
			radToggleButton1.DataBindings.Add(b);
		}

		void b_Parse(object sender, ConvertEventArgs e)
		{
			if (e.DesiredType != typeof(bool) || !(e.Value is ToggleState))
				return;

			ToggleState state = (ToggleState)e.Value;
			e.Value = (state == ToggleState.On) ? true : false;
		}

		void b_Format(object sender, ConvertEventArgs e)
		{
			if (e.DesiredType != typeof(ToggleState) || !(e.Value is bool))
				return;

			bool isToggleOn = (bool)e.Value;
			e.Value = isToggleOn ? ToggleState.On : ToggleState.Off;
		}
