Set Maximum and Value of RadTrackBar to 100. When you run the application, the thumb will be at the wrong position.

Wrong painting in waiting bar in Dash style

When the size of RadTrackBar is set to less than 90 pixels (69 in this case) the last tree thumbs steps remain hidden (invisible). 

To reproduce: Set the track bar value to 10 and increment by one every lets see button click. When the values reaches 8, the thumb is already out of the bounds of the track bar.

When  you increase the SmallTickFrequency and use the TrackBarSnapModes.SnapToTicks, moving the thumb with the mouse should snap to the visible ticks. 

When RadTrackBar is resized at runtime, the position of the thumb is not changed.

To Reproduce:
      Me.RadTrackBar1.Value = 5

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);

When initially loaded, RadTrackBar's thumb is not aligned properly.

Start dragging the thumb with the mouse and note that the thumb at first moves into the opposite direction. After a few pixels the thumb starts moving in the correct direction, however, this makes the thumb appear not under the mouse, but some pixels away.

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 waiting bar to a user control.
- Try setting the assoitad control in the smart tag.
 
 Workaround:
- Set it in code.

To reproduce:
private void radButton1_Click(object sender, EventArgs e)
{
    radTrackBar1.Maximum = 100;
    radTrackBar1.Value = 200;
  
}

Workaround: use the attached custom theme

If you set the Office2010Silver theme to RadProgressBar and set the BackColors of the UpperIndicator through the Edit UI Elements dialog, you will notice that your colors are not shown and you still get the colors defined by the theme. It seems that this behavior is determined by the DrawFill property of the UpperIndicator which is false. This is interesting, because if DrawFill is false, the UpperIndicator should not be visible at all.
This behavior is due to the fact that in Office2010 themes the UpperIndicator fill is ImageShape and not a gradient fill.

The thumb is not updating when the value is changed in design time.

When clicking on the progress bar element the Click event is not fired.

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.

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.

RadProgressBar IndicatorElement1 and IndicatorElement2 have two missing pixels on the top right corner with ControlDefault and Breeze themes.

Workaround:
Set a -1 top margin to both elements - IndicatorElement1 /IndicatorElement2

#1 Scenario: Drag and drop the RadTrackbar to form. Set the Orientation to Vertical. Run the project and you will see that control is not visible
public Form1()
{
    InitializeComponent();
    this.radTrackBar1.Orientation = Orientation.Vertical;
}





#2 Scenario:  Drag and drop the RadTrackbar to form. Set the Orientation to Vertical. Run the project and you will see that control is cut off
private void Form1_Load(object sender, EventArgs e)
{
    this.radTrackBar1.Orientation = Orientation.Vertical;
