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: 

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

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

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:
- Add a RadPageView with several pages to a form.
- View the tabs by setting the SelectedTab property.
- Create a form instance and show it with the ShowDialog method.
- Select the second tab.
- Reopen the form and select a tab after the second. You will notice that the content is not changed.
 
Workaround:
Create a new instance each time when the form is shown.

To reproduce:

1. Add a RadPageView with several pages.
2. Disabled some of the pages.
3. When running the application, try to navigate through pages with the arrow keys. You will notice that the disabled pages are also selected.

Workaround: 

public class CustomPageView : RadPageView
{
    public override string ThemeClassName  
    { 
        get 
        { 
            return typeof(RadPageView).FullName;  
        }
    }

    protected override RadPageViewElement CreateUI()
    {
        if (this.ViewMode == PageViewMode.Strip)
        {
            return new CustomViewElement();
        }
        return base.CreateUI();
    }
}

public class CustomViewElement : RadPageViewStripElement
{
    protected override Type ThemeEffectiveType     
    { 
        get    
        { 
            return typeof(RadPageViewStripElement);     
        }
    }

    protected override bool CanSelectItem(RadPageViewItem item)
    {
        bool result= base.CanSelectItem(item);
        return result && item.Enabled;
    }
}

Hello,
PageView with Windows8 Theme, ViewMode Stack, Stack Position Left
Tabs are drawn incorrectly, see attachment.
can i work around this issue?
Thanks

1. Place a RadPageView in ExplorerBar view mode on a from.
2. Add page and place any RadControl in the page content panel.
3. Close (Collapse) the page.
4. Save and close the form.
5. Open the form and open(expand) the page and you will see that the control will be stretched more than when you saved the form.

To reproduce:
- Add RadPageView change the view  to ExplorerBar and add some pages with controls.
- Start the application expand all pages and scroll.

Workaround:
class MyPageView : RadPageView
{
    protected override RadPageViewElement CreateUI()
    {
        if (this.ViewMode == PageViewMode.ExplorerBar)
        {
            return new MyExplorerBarElement();
        }
        return base.CreateUI();
    }
   
}

class MyExplorerBarElement : RadPageViewExplorerBarElement
{
    protected override bool IsChildElementExternal(Telerik.WinControls.RadElement element)
    {
        return !(element is RadPageViewElementBase) && base.IsChildElementExternal(element);
    }
    protected override Type ThemeEffectiveType
    {
        get
        {
            return typeof(RadPageViewExplorerBarElement);
        }
    }
}

To reproduce:
1. Add a RadPageView with no pages and set its Dock property to Fill.
2. Set the ViewMode property to ExplorerBar at design time.
3. Use the following code snippet:

private void AddOutputPage(int index)
{
    string title = "Test-Page " + index;
    RadPageViewPage page = new RadPageViewPage(title);
    this.radPageView1.Pages.Add(page); 
}

private void Form1_Load(object sender, EventArgs e)
{
    for (int i = 0; i < 20; ++i)
        AddOutputPage(i);
}

As a result the current page header at the top of the RadPageView is not displayed until you resize the pageview.

Steps to reproduce:

1. Add a RadPageView to a form and add a page
2. Add some controls to the page.
3. Open the RadPageView smart tag and click Remove Page
4. Select from Visual Studio Edit->Undo and you will see that the page will be restored but the controls on it will not be restored properly.
If one removes the page using the keyboard Delete key the undo functionality of VS works correctly.
