To reproduce:

1. Add a form with a RadRibbonBar and add some tabs

2. Create a second form that inherits the first one

3. Open the second form at design time and add a few items to the application menu.

Expected: either the applied changes in the derived form should be serialized properly or the ribbon in the derived form should be locked for such changed.

Actual: even though the menu items are added in the designer and you can see them, after restarting the designer, they are not shown in the application menu anymore. You can see that they are still available in the Designer.cs but they are not added to the application menu. The same behavior is observed if you add tabs and groups with different elements.

When the HorizontalAxisStroke is not specified, an error occurs during the document's loading.

Use the sample project and follow the illustrated steps in the gif file.

Expected: when you hover a page and it has sub pages, the popup is shown automatically. When you hove another page while the popup is still opened, it shouldn't remain opened.

Actual: when you hover a page and it has sub pages, the popup is shown automatically. When you hove another page while the popup is still opened, it should be closed.

Implement functionality to rotate the text in a cell.

When closing the MDI child, its FormClosing event is called twice. This is not observed if we close its HostWindow first.

Steps to reproduce:

Create new Telerik Windows Forms Application ( I use VB.net but this crashes in C# as well )

Create RadRibbonForm - set the Project so this is the Startup Form.

Add Office2013LightTheme to form.

Set RadRibbonBar1.ThemeName to Office2013LightTheme.

Set ApplicationMenuStyle property = BackstageView

Run the ap, click on the Backstage tab and you'll see the first Image attached (called First.png)

Close the ap and back to Visual Studio - with the Form open in the Designer.

Everything is set but now i want to change the Background color of that lovely blue panel and everything inside it to a new background color.

I'd like to do this without creating a new Theme.

Click on the little triangle thingie in the upper right corner and select "Edit UI Elements"

Look down the Tree until you see BackstageItemsPanelElement.

Set BackstageItemsPanelElement.BackColor = 64, 53, 130

Close the Edit UI Elements dialog box and save then Start.  

Open the Backstage and you can see the "Back Button" at the very top still has the blue backcolor (No clue why this object doesnt get it's background from its Parent but it does not) so lets fix the background color for that button.

Close the Ap if its still running.  Open the form in VS Designer.  Edit UI Elements.  Look down until you find this:

RootRadElement.BackstageViewElement.BackstageItemsPanelElement.RadButtonElement.FillPrimitive

Set RadButtonElement.FillPrimitive.BackColor = 64, 53, 130

and we have to get the border - found under the RadButtonElement.BorderPrimative.FORECOLOR

Set RadButtonElement.BorderPrimative.ForeColor = 64, 53, 130

Close Element hierarchy editor.  Save and Run.

Everything looks great now right!??  Attached image #3 (Second.png)

If you examine form.designer.vb you will see these three lines have been added:

This is the BackstageItemsPanelElement.Backcolor we changed:

CType(Me.myBackStage.GetChildAt(0).GetChildAt(2), Telerik.WinControls.UI.BackstageItemsPanelElement).BackColor = System.Drawing.Color.FromArgb(CType(CType(64, Byte), Integer), CType(CType(53, Byte), Integer), CType(CType(130, Byte), Integer))

This is the Back Button's FillPrimitive we changed (NOTE Indexes 0, 2, 0, 0)

CType(Me.myBackStage.GetChildAt(0).GetChildAt(2).GetChildAt(0).GetChildAt(0), Telerik.WinControls.Primitives.FillPrimitive).BackColor = System.Drawing.Color.FromArgb(CType(CType(64, Byte), Integer), CType(CType(53, Byte), Integer), CType(CType(130, Byte), Integer))

And this is the Back Button's BorderPrimitive we changed (NOTE Indexes 0, 2, 0, 2)

CType(Me.myBackStage.GetChildAt(0).GetChildAt(2).GetChildAt(0).GetChildAt(2), Telerik.WinControls.Primitives.BorderPrimitive).ForeColor = System.Drawing.Color.FromArgb(CType(CType(64, Byte), Integer), CType(CType(53, Byte), Integer), CType(CType(130, Byte), Integer))

And now to the CRASH.

Close the ap if still running. 

Open the form in Designer. 

Switch to Backstage. 

Click on the triangle thing again and this time Click on "Add Tab Item"

Save your form.

Close the form (Designer)

Now try to reload the form in the Designer.

CRASH!!!

You get a Dialog that i believe the Ribbon is throwing (Or more precisely the Backstage object) that says "Error parsing RadItem:  Children collection index is not valid: 0 - 2 - 0 - 0" - See attached image "Crash.png" - this is followed by another almost identical error dialog box except this one will say "0 - 2 - 0 - 2" 

Those three lines i posted above that were added to the form.Designer.vb code the first one is fine and has no issues.  The next two lines however are what's causing the problems (FillPrimitive and BorderPrimitive)

Any help anyone can offer would be very very appreciated at this time.  I've spent two days trying to work this out.  If there's no way to fix this can anyone suggest an alternate way for me to change those background colors without altering the Theme? 

Cheers all!

Run the project and load a document with bookmarks. Try to click the two buttons in order to switch between thumbnails/bookmarks. 

        private void radButton1_Click(object sender, EventArgs e)
        {
            this.radPdfViewer1.ShowThumbnails();
        }

        private void radButton2_Click(object sender, EventArgs e)
        {
            this.radPdfViewer1.ShowBookmarks();
        }

Expected: clicking the two buttons should switch between bookmarks/thumbnails

Actual: the user is stuck to bookmarks

Steps to reproduce the issue:

1. Run the example app.
2. Click undo (the last item is removed).
3. Click redo (the last item should be added to the Treeview, it does not)
If I run the application and click undo twice and then redo twice, the things work. The Treeview is not updated if I add and remove the same element instance to the binding list.

Workaround: rebind the treeview after redo or create a new instance of the Element class with the same name and id.

When a document is imported from HTML, we set locally to the span elements Times New Roman nevertheless it is not declared anywhere. This breaks the document view if for example we decide to change the RadDocument's default font family or even the NormalWeb style's font. The same applies for the font size as well.

Workaround: Clear the FontFamily property after import

foreach (Span span in this.radRichTextBox.Document.EnumerateChildrenOfType<Span>())
{
    span.GetStyleProperty(Span.FontFamilyProperty).ClearValue();

   span.GetStyleProperty(Span.FontSizeProperty).ClearValue();

}

Steps to reproduce:

1. Import the following html:

this.radRichTextBox.Document = new HtmlFormatProvider().Import(@"<h1>Hello</h1><h2>World</h2><p>Lorem ipsum<p>");

2. Set the document's default font family to Comic Sans MS:

this.radRichTextBox.Document.Style.SpanProperties.FontFamily = new FontFamily("Comic Sans MS");

Observe: The font in the document is Times New Roman

Expected: The font should be Comic Sans MS

To reproduce the issue, just drag a RadToggleSwitch to the form. Then, at run time call the method:

radToggleSwitch1.SetToggleState(newValue: false, animate: false);

You will notice that the colors are changed but the thumb is not moved: 

Workaround:

            this.radToggleSwitch1.AllowAnimation = false;
            this.radToggleSwitch1.Toggle();
