To reproduce: RadButton button = new RadButton(); button.AutoSize = true; button.MaximumSize = new Size(74, 0); button.Text = "Define Horizontal Measurement"; Controls.Add(button); WORKAROUND: set the MaxSize property of the border primitive to the same value as the MaxSize of the control: button.ButtonElement.BorderElement.MaxSize = new Size(74, 0);

Steps to reproduce:
1. Create a form that is MDI Parent
2. Create a form that would be and MDI Child.
3. Add a RadSplitButton to the MDI Child form and set it's anchor to Bottom | Left.
4. Set the WindowState of the MDI Child to be Maximized.
5. In a Form.Load event handler of the MDI Parent add an MDI Child form.
Run the project and you will see that the RadSplitButton is in the wrong location.

To reproduce add RadDock to a form and use the following code on a button click.
           DocumentWindow document = new DocumentWindow();
            radDock1.AddDocument(document);
            document.TabStripItem.ShowCloseButton = true;
            document.TabStripItem.CloseButton.Image = image1;
            document.TabStripItem.CloseButton.ImageHovered = image2;
            document.TabStripItem.CloseButton.ImageClicked = image3;

The result is that instead of having three different images for the different states, only the main Image is displayed.

FIX. RadRadioButton shape can not be set with Office2010 themes
COMMENT. In order to achieve the required design all Office2010 themes use Image Shapes. When an Image Shape is applied to an element, its shape cannot be customized. Thus, the behavior observed in the QSF > Buttons > RadRadioButtons demo, i.e. custom shapes cannot apply to the RadioMark and the CheckMark, is expected.

The theme is not applied properly when the button is toggled off.

Add DefaultItem property in the property grid and allow to set it in design time

Setting the Font property of RadButton will not change the font in all states of the control. Currently, the issue can be avoided through setting the Font property of the ButtonElement.

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)

When a RadCheckBox is in Indeterminate state, the user should be able to see a square instead of checkmark.

To reproduce, create a RadButton on a form with the below settings.  The image is any 32x32 image. 

this.radButton1.Font = new System.Drawing.Font("Segoe UI", 11F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0))); 
this.radButton1.Image = global::TestPopup.Properties.Resources.Image32x32; 
this.radButton1.Location = new System.Drawing.Point(13, 13); 
this.radButton1.Size = new System.Drawing.Size(131, 44); 
this.radButton1.Text = "The Quick Brown Fox"; 
this.radButton1.TextAlignment = System.Drawing.ContentAlignment.MiddleLeft; 
this.radButton1.TextImageRelation = System.Windows.Forms.TextImageRelation.ImageBeforeText; 
this.radButton1.TextWrap = true;

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;
		}

RadSplitButton does not get a focus rectangle when focus by the Tab key. One should first click the action part and then the focus rectangle will appear..

The current workaround is:
public class MyRadSplitButton : RadSplitButton 
{ 
    protected override void OnEnter(EventArgs e) 
    { 
        base.OnEnter(e); 
  
        this.DropDownButtonElement.ActionButton.Focus(); 
    } 
}

RadCheckBox can be checked by the right mouse button

When image is being inserted to the ActionButton in RadSplitButton the ArrowButton might get overlaped if the text of the ActionButton is very long.

Workaround is to subtract the width of the image from the width of the text manually.

int actionButtonWidth = radSplitButton1.DropDownButtonElement.ActionButton.Size.Width;
int imageWidth = 40; // Sample rate should be equal to the width of the image in pixels

int desiredTextWidth = actionButtonWidth - imageWidth;

radSplitButton1.DropDownButtonElement.ActionButton.TextElement.MaxSize = new Size(desiredTextWidth, 0);

radSplitButton1.DropDownButtonElement.ActionButton.TextWrap = true;

Coping RadDropDownButton in design time leads to improperly distributed items collection.

Please use the following code snippet and try to resize the button as it is illustrated in the attached gif file: 

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

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

Add support for UI Automation in RadButton control.

If there are boolean application Settings:

It is good to have the possibility to bind the Checked property for RadCheckBox in a similar way like the MS CheckBox offers:

RadCheckBox offers only the Text option:
