This happens if the file is not first in the selected files list.

Steps to reproduce:

1. Add 2 files for upload. The first one should be bigger so you have time do to the next steps.
2. Click the Upload button. The first starts to upload.
3. Delete the second file.

When the upload process gets to the second file, a NullReferenceException is thrown.

The issue is replicated only when a filtering operation is applied. For a grouping and sorting one it is not. In Silverlight when the new source collection is set, the column headers are cleared and empty rows are displayed. In WPF the item is not cleared. The workaround is to clear the FilterDescriptors collection of RadGridView before assigning the new instance of the source collection.

The control is misplaced when you zoom in/out the browser window.

To work this around you can manually calculate and set the top and left positions of the HTML presenter. 

this.htmlPlaceholder.Loaded += (sender, args) => { this.htmlPlaceholder.LayoutUpdated += htmlPlaceholder_LayoutUpdated; };

private void htmlPlaceholder_LayoutUpdated(object sender, EventArgs e)
        double controlTop = GetTop();
        double controlLeft = GetLeft();
        htmlPlaceholder.HtmlPresenter.SetStyleAttribute("top", controlTop + "px");
        htmlPlaceholder.HtmlPresenter.SetStyleAttribute("left", controlLeft + "px");

Silverlight only bug.

TreeView is bound to observable collection of strings.

Theme is changed. Then 10 times is done (remove + add) operation in the source collection.

IndexOutOfRangeException is thrown in Set method of IndexTree.cs.

If you place a TextBlock in the QuickAccessToolbar and the Ofice_Black theme is applied you get black foreground on black background which makes the text unreadable. The content of the QAT must respect the theme applied to the RadRibbonView control.
