Controls in RadPanel redraw slowly when changing the Enabled state of the panel.

Workaround:

private void radButton1_Click(object sender, EventArgs e)
{
    if (this.radPanel1.Enabled)
    {
        this.radPanel1.Enabled = false;
    }
    else
    {
        this.radPanel1.Visible = false;
        this.radPanel1.Enabled = true;
        this.radPanel1.Visible = true;
    }
}

To reproduce: add a RadCollapsiblePanel and insert several controls at run time with specifying the location and size of the inner controls. Set the ContentSizingMode property to CollapsiblePanelContentSizingMode.FitToContentHeight | CollapsiblePanelContentSizingMode.FitToContentWidth. When you run the application you will notice that the inner controls are cut off and the panel is not resized according to its content.

Release R2 2019 SP1
To reproduce:
- Use the attached project.
- Resize the panel to the left.
- You will notice that the borders are cut off.

Second scenario: refer to the 1016234GridInCollapsiblePanelVS2010.zip
RadCollapsiblePanel1.ExpandDirection = Telerik.WinControls.UI.RadDirection.Right
RadSplitContainer1.SplitPanels("SplitPanel2").SizeInfo.SizeMode = Telerik.WinControls.UI.Docking.SplitPanelSizeMode.Absolute
RadSplitContainer1.SplitPanels("SplitPanel2").SizeInfo.AbsoluteSize = New System.Drawing.Size(637, 522)

Workaround: manually update the collapsible panel`s size in the SplitterMoved event
public WorkCenterScheduleAndStatusControl()
{
    InitializeComponent();

    this.radSplitContainer1.SplitterMoved += RadSplitContainer1_SplitterMoved;
}

private void RadSplitContainer1_SplitterMoved(object sender, SplitterEventArgs e)
{
    this.radCollapsiblePanel1.Size = new Size(this.radCollapsiblePanel1.Size.Width, this.radCollapsiblePanel1.Size.Height - 1);
    this.radCollapsiblePanel1.Size = new Size(this.radCollapsiblePanel1.Width, this.radCollapsiblePanel1.Size.Height + 1);
}

To reproduce: 
1. Add a RadSplitContainer with two split panels.
2. Add a RadCollapsiblePanel to the left split panel and set the RadCollapsiblePanel.Dock property to Fill.
3. Add a RadGridView inside the RadCollapsiblePanel  and set the RadGridView.Dock property to Fill.
4. Populate the grid with data.
5. Run the application and move the splitter to increase the RadCollapsiblePanel's size. The RadGridView is resized correctly.
6. Move the splitter to shrink the RadCollapsiblePanel. As a result the grid is not resized correctly. 

Workaround:

Subscribe to the RadSplitContainer.SplitterMoved event and use the  following code:

this.RadCollapsiblePanel1.EnableAnimation = false;
this.RadCollapsiblePanel1.IsExpanded = !this.RadCollapsiblePanel1.IsExpanded;
this.RadCollapsiblePanel1.IsExpanded = !this.RadCollapsiblePanel1.IsExpanded;
this.RadCollapsiblePanel1.EnableAnimation = true;

Description: For a RadScrollablePanel (VerticalScrollbar is visible) with a RadSpinEditor inside it, when the user is scrolling the mouse wheel in order to change the RadSpinEditor value, both controls (the RadScrollablePanel and the RadSpinEditor) are affected.

To reproduce:
- add a RadScrollablePanel with several controls inside it (VerticalScrollbar is visible) 
- add a RadSpinEditor inside the RadScrollablePanel 
- scroll the mouse wheel in order to change the RadSpinEditor value

Workaround:
this.radSpinEditor3.SpinElement.TextBoxItem.HostedControl.MouseWheel+= HostedControl_MouseWheel;

private void HostedControl_MouseWheel(object sender, MouseEventArgs e)
        {
            if (this.radSpinEditor3.ReadOnly || !this.radSpinEditor3.SpinElement.EnableMouseWheel)
            {
                return;
            }

            HandledMouseEventArgs handledMouseEventArg = e as HandledMouseEventArgs;
            if (handledMouseEventArg != null)
            {
                if (handledMouseEventArg.Handled)
                {
                    return;
                }
                handledMouseEventArg.Handled = true;
            }           
        }

When AutoSize is false, TextWrap is true, TextImageRelation is ImageBeforeText and RadLabel has a padding set, the text does not wrap correctly.

When the control is anchored to bottom left and its text is set to empty string in the form's Load event its position is changed.

To workaround this you can either set the text to a space or you can set the text in the form's shown event:
Private Sub Form1_Shown(sender As Object, e As EventArgs) Handles MyBase.Shown
    RadLabel2.Text = ""
End Sub

To reproduce:
var stackPanel = new StackLayoutElement { Orientation = Orientation.Vertical };
stackPanel.Children.Add(new TextPrimitive { Text = "Demo" });
 stackPanel.Children.Add(new TextPrimitive { Text = "Demo" });
Panel.PanelElement.Children.Add(stackPanel);
Panel.AutoSize = true; // <= false works fine

Workaund:
- Put the panel in a control:
public class MyControl : RadControl
{
    protected override void CreateChildItems(RadElement parent)
    {
        base.CreateChildItems(parent);
        
        var stackPanel = new StackLayoutElement { Orientation = Orientation.Vertical };
        stackPanel.Children.Add(new TextPrimitive { Text = "Demo" });
        stackPanel.Children.Add(new TextPrimitive { Text = "Demo" });

        parent.Children.Add(stackPanel);
    }

    protected override RootRadElement CreateRootElement()
    {
        RootRadElement root = base.CreateRootElement();
        root.BackColor = Color.Transparent;

        return root;
    }
}

Use attached to reproduce.

Workaround:

- Use RadForm it explicitly handles the controls scaling. 
- Make sure that the following of the user controls are set like this:

this.AutoScaleDimensions = new System.Drawing.SizeF(96F, 96F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi;
