 How to reproduce
1. Drag a RadTrackBar from the toolbox
2. Set the Maximum property, e.g. to 100, set the Minimum property, e.g. to 50
3. Close and reopen the designer, you will notice that the Minimum property of the control is not the expected value of 50, although it has been properly serialized in the designer file.

Workaround: 
set the Minimum property in the Load event of the form

To reproduce:

radTrackBar1.SmallTickFrequency = 10;
radTrackBar1.TickStyle = TickStyles.None;
radTrackBar1.SnapMode = TrackBarSnapModes.None;

The user is not allowed to move the slider at all. If you set the Minimum property to 0 and the Maximum to 100, you will be able to slide to the right a little bit.

Workaround: use TickStyles.Both

To Reproduce:

Add a RadDropDownButton on a form, then create a RadMenuItem and a RadTrackBarElement element. Add the trackbar to the children`s collection of the menu item, then add the menu item to the items`s collection of the RadDropDownButton element. Application freezes when you move the drag ball and it gets close to the end of the trackbar.

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();

        RadTrackBarElement trackBar = new RadTrackBarElement();
        //trackBar.StretchHorizontally = false;

        RadMenuItem menuItemTrackBar = new RadMenuItem();
        menuItemTrackBar.Children.Add(trackBar);
        this.radDropDownButton1.Items.Add(menuItemTrackBar);
    }
}

Workaround:

Set StretchHorizontally property of the trackbar to False.

trackBar.StretchHorizontally = false;

1.Add a UserControl.
2.Drag a TableLayoutPanel from the Toolbox and drop it onto the UserControl. Set its Dock property to Fill.
3.Add 3 columns to the TableLayoutPanel:
	Column1 50%
	Column2 20%
	Column3 30%
4.Add 3 rows to the TableLayoutPanel:
	Row1 Absolute 20
	Row2 Percent 100%
	Row3 Absolute 30
5.Add a RadTrackBar to the second row in the TableLayoutPanel and set its Dock property to Fill. Change the ColumnSpan property to 3.
6.Set the RadTrackBar.AutoSize property to false.
7.Open the designer and resize the user control on a way to make its size very small. As a result Visual Studio hangs.

RadTrackBar - the scroll event is throwing when value is changed through code.

Workaround: Use flag to distinct whether the value was changed interactively or programmatically.

Fix. RadTrackBar - TrackBarIndicatorElement does not resize correctly, when RadTrackBar is resizing in run time and Maximum value of RadTrackBar is set to 2000. Steps to reproduce: 1. Use this code: this.radTrackBar1.LargeTickFrequency = 200; this.radTrackBar1.SmallTickFrequency = 25; this.radTrackBar1.Maximum = 2000F; 2. Resize the RadTrackBar in run time when thumb is at max value.

RadTrackBarElement - has incorrect behavior when AutoSize property is false. If you set value to be equals to Maximum the thumb will be go out of the TrackBar's rectangle.

Workaround:
Turn off auto size and manually set the desired size of the element. For example:

this.radTrackBarElement1.AutoSize = false;
this.radTrackBarElement1.Size = new System.Drawing.Size(100,20);
