To reproduce: please refer to the attached sample project and gif file. The purpose is to select the last added page. However, the multi-line tabs are not ordered correctly at all compared to the TabControl.

A possible workaround here is to make the panel parent of the buttons visible.

RadPageViewStripElement element = this.radPageView1.ViewElement as RadPageViewStripElement;
element.ItemContainer.ButtonsPanel.DrawFill = true;
element.ItemContainer.ButtonsPanel.NumberOfColors = 1;

How to reproduce: check the attached project:

Workaround: when the form is opened in the designer make sure that all pages are made visible at least ones so the controls are initialized, before attempting to access collection editors via properties window

The layout on a monitor with 100%:

After moving the form to a monitor with higher than 100% DPI scaling, e.g. 175% or greater:

Once you switch to the first page which contains exactly the same UserControl, the layout is not correct:

How to reproduce: 

public Form1()
{
    InitializeComponent();

    this.radPageView1.ItemSizeMode = Telerik.WinControls.UI.PageViewItemSizeMode.EqualSize;
    this.radPageView1.ItemSize = new Size(50, 20);
}

I attached a video and the code I used. I am trying to remove and add pageviews. (I would hide them it i knew how)

When I add the pageview back in while the hamburger menu is closed it somewhat expands the tabs. I would like it to leave it closed

When you have RadPageView within a RadDock only the selected page is visible and its content is shown. When you select another page it is blank.

Workaround:

To reproduce:
- Open attached project and add a lot of pages. 
- Close all pages 
- The GDI object count increases. 

Workaround:
GC.Collect();
GC.WaitForPendingFinalizers();
GC.WaitForFullGCApproach();
GC.WaitForFullGCComplete();
GC.Collect();

To reproduce: add a RadPageView in NavigationView and set the following property:


        Dim view As RadPageViewNavigationViewElement = TryCast(Me.RadPageView1.ViewElement, RadPageViewNavigationViewElement)

        view.CollapsedPaneWidth = 300 

The expected result is that the navigation view default's width is set to 300 when loading. However, it is adjusted when you expand and collapse the hamburger.

When you set the RightToLeft property to Yes, you will obtain incorrect layout. Please refer to the attached gif file.

To reproduce: please follow the steps illustrated in the attached gif file. 

Workaround: add pages as follows: Click the Smart Tag of RadPageView and then click the Add Page link five times. Additional information how to get started with RadPageView is available in the following help article: https://docs.telerik.com/devtools/winforms/pageview/stripview/getting-started

Workaround: this.radPageViewPage1.Item.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAliasGridFit;

To reproduce: please refer to the attached sample project and follow the illustarted steps in the attached gif file.

Steps to reproduce: 
1. Set the main screen on 125-percent scale
2. Run attached sample application (1107416 RadPageView Issue.zip). 
3. Click menu item "ShowPageView". After showing the page view in a DocumentWindow, the SelectedPageChanging/SelectedPageChanged events are fired twice. 

Workaround: 
Replace RadPageView with custom one: 
public class CustomPageView : RadPageView
{
    protected override void ScaleControl(SizeF factor, BoundsSpecified specified)
    {
        this.SuspendEvents();
        base.ScaleControl(factor, specified);
        this.ResumeEvents();
    }
}

Let's say that you have RadPageView in ExplorerBar mode and the Content Size mode is set to AutoSizeToBestFit. Dock two buttons in the content area to top. Run the app and you will see that the bottom of the second button is cut in some themes. This is because these themes has a border set to the content area. The border is taken into consideration by the layout and the content is cut even throught there is space for it. This happens with Windows7, Office2010Black and other themes.

One can't set the image scaling of the pages' tabs. For example if you have a big image and you want to scale it down to a size of 10x10, you will not be able to do so.

To reproduce: use the following code snippet:

public RadForm1()
{
    InitializeComponent();

    this.radPageView1.Pages.Add(new RadPageViewPage("My page"));
    RadPageViewStripElement stripElement = this.radPageView1.ViewElement as RadPageViewStripElement;
    stripElement.StripButtons = StripViewButtons.ItemList;

    this.radPageView1.ItemListMenuDisplaying += radPageView1_ItemListMenuDisplaying;
}

private void radPageView1_ItemListMenuDisplaying(object sender, RadPageViewMenuDisplayingEventArgs e)
{
    e.Items.Clear();
    RadMenuItem item = new RadMenuItem("aaa");
    e.Items.Add(item);
}


Click the overflow button to open the drop down and select the item. When you open the overflow popup again you will notice that the item is duplicated although you clear the items in the ItemListMenuDisplaying event.

Workaround: dispose the item when it is clicked

private void radPageView1_ItemListMenuDisplaying(object sender, RadPageViewMenuDisplayingEventArgs e)
{
    e.Items.Clear();
    RadMenuItem item = new RadMenuItem("aaa");
    item.Click += item_Click;
    e.Items.Add(item);
}

private void item_Click(object sender, EventArgs e)
{
    RadMenuItem item = sender as RadMenuItem;
    if (item != null)
    {
        item.Click -= item_Click;
        item.Dispose();
    }
}
