Setting RadDropDownButtonElement MinSize property does not make the RadDropDownButton control stretch to fit its element.

Currently, the issue can be avoided through adding the following three lines of code:
            this.radDropDownButton1.RootElement.StretchHorizontally = false;
            this.radDropDownButton1.RootElement.StretchVertically = false;
            this.radDropDownButton1.RootElement.SaveCurrentStretchModeAsDefault();

ToggleStateChanging event is fired before the KeyDown event which should actually trigger the toggle
change operation. This happens when you press the Enter key.

To reproduce:


Add a RadButton to a form. Set an image, remove the text and set the shape of the ButtonElement to a new RoundRectShape. You will see that the image will not be painted with a shape.


Workaround:


Paint the image manually:


Image img = Image.FromFile(@"jpg.jpg");
RoundRectShape shape1 = new RoundRectShape(10);


protected override void OnLoad(EventArgs e)
{
    this.button = new RadButton();
    this.button.Parent = this;
    this.button.ButtonElement.Shape = shape1;
    this.button.Paint += button_Paint;
}


void button_Paint(object sender, PaintEventArgs e)
{
    e.Graphics.SetClip(shape1.CreatePath(new Rectangle(Point.Empty, this.button.Size)));
    e.Graphics.DrawImage(img, new Rectangle(Point.Empty, this.button.Size));
}

To reproduce:

Add a RadTextBox and a RadButton to a form. On the Leave event of RadTextBox show a RadMessageBox. Start the application. Focus the textbox and click the button. The RadMessageBox will show, click the OK button and now you will see that the button is in its 'IsDefault' state (it is a bit more obvious with the Office2010 themes) and no other controls receive mouse input unless you click on the form.

Workaround:

Set the CausesValidation property of RadButton to false.

To reproduce: 
1. Open the Demo application >> Button example.
2. Change the theme to TelerikMetroBlue.
3. Click with the right/middle mouse button and you will notice that the button clicked states is indicated.

Workaround: remove the MouseDown state in Visual Style Builder for the fill element as it is illustrated on the attached screenshot.

To reproduce:
- Add 3 radio buttons to a user control.
- Set the ToggleState of the second radio button to  On.
- Show the user control in a DockWindow.
- You will notice that the first toggle button is selected.

Workaround:
Set the toggle state after the window is added to the RadDock
void radDock1_DockWindowAdded(object sender, Telerik.WinControls.UI.Docking.DockWindowEventArgs e)
{
    if (e.DockWindow.Text == "UserControl11")
    {
        UserControl1 uc1 = e.DockWindow.Controls[0] as UserControl1;
        ((RadRadioButton)uc1.Controls[1]).ToggleState = Telerik.WinControls.Enumerations.ToggleState.On;
    }

To reproduce:
- Create a dpi aware application and add a checkbox to it. 
- Change your DPI setting to 200% and start the application.
- The checkmark is not scaled only the text is. 

Workaround:
this.radCheckBox2.ButtonElement.CheckMarkPrimitive.CheckElement.UseFixedCheckSize = false;
this.radCheckBox2.ButtonElement.CheckMarkPrimitive.CheckElement.MinSize = new Size(100, 100);

Release R1 2019
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;
        }

Please refer to the attached sample project and gif file. The text gets clipped sometimes when resizing the form. It may become even blurry. This problem is observed with the MS Form, but it is not reproducible with RadForm.

Workaround: use a RadForm

UPDATED: a second project is attached (00393359CheckBoxDisabledUPDATED.zip). The MissingCheckBoxesText.gif illustrates the incorrect behavior. In this case, the UseCompatibleTextRendering property is set to false.
Workaround for the second case: instead of setting the RadCheckBox.Enabled property to false, disabled the check primitive and make the text gray as follows:

private void radButton1_Click(object sender, EventArgs e)
{
    for (int i = 0; i < 30; i++)
    {
        RadCheckBox cb = new RadCheckBox();
        cb.Text = "RadCheckBox " + i;
        cb.Location = new Point(10, i * 30); 
        cb.ButtonElement.CheckMarkPrimitive .Enabled = false;
        cb.ButtonElement.TextElement.ForeColor = Color.Gray; 
        cb.ButtonElement.ShouldHandleMouseInput = false;
        cb.UseCompatibleTextRendering = false;
         
        this.Controls.Add(cb);
    }
}
