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

To reproduce:
- Set the mode and add ranges from the properties window.
- The ranges are not added to the track bar

Workaround:
- Use the smart tag or add the ranges in code.

This functionality is applicable to the controls that support search functionality like RadRichTextEditor, RadGridView etc.

Workaround: use the attached custom theme

To reproduce:
private void RadForm3_Shown(object sender, EventArgs e)
{
    Telerik.WinControls.UI.RadWaitingBar waitbar = new Telerik.WinControls.UI.RadWaitingBar();
    pnlCenter.Enabled = false;
    waitbar.AssociatedControl = pnlCenter;
    waitbar.StartWaiting();
}

Workaround:
Do not disable the control while using the waiting bar

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

ADD. RadTrackBar - add functionality for changing the value of the control with arrow keys

#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;
}

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.

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;

Workaround:
Set the styles for the WaitingBarSeparator in Visual Style Builder (you can see how this is set for the other themes).

To reproduce:
- Add RadTrackbar to a form and set its minimum and maximum to negative values.
- Start the application, the maximum is reset to 1.

Workaround:
Set the maximum at runtime. 

The LargeChange property sets the change in value that one click of the mouse outside of the slider makes. Let's say that the position of your thumb is at the beginning of the RadTrackBar (at position 0), the value of this property is 5 and you click on tick number 14. The thumb will reposition itself to tick number 5, following the step determined by the LargeChange property. However, if the LargeChange has value 0, the thumb will move to position 14. It is necessary to be added another property to control the step when changing the value when using the left/right buttons, e.g. SmallChange.
