When a workbook protection is applied, changing the color of a tab in the sheet selector shouldn't be allowed.

Workaround: Remove the Tab Color item from the Items collection of the SheetSelectorContextMenu.

If the RadSpreadsheet is declared as a child content in the RadBusyIndicator, there isn't any tab selected as active in the SheetSelector.

Workaround: Declare the busy indicator after the RadSpreadsheet not as its child.

For example, instead of:

<telerik:RadBusyIndicator>
    <telerik:RadSpreadsheet x:Name="radSpreadsheet" />
</telerik:RadBusyIndicator>

Do:

<Grid>
    <telerik:RadSpreadsheet x:Name="radSpreadsheet" />
    <telerik:RadBusyIndicator />
</Grid>

The default set of WPF UI controls measured in infinity results in the minimal size of the control. RadSpreadsheet should behave the same. This will help users to find out what is happening while debugging.

DataValidationRule is persisted after pasting a cell value which is copied from a cell without DataValidationRule applied. 

For example: Cell A1 has data validation rule applied. The cell A2 doesn't have. The value from cell A2 is copied to cell A1. The result is that cell A1 still has data validation, but it shouldn't.

LocalizableException with text "Format string is not in the correct format.", with inner ArgumentException "Format string is not in the correct format." is thrown. 

Currently the validation doesn't allow number format string starting with date or time formatting to have more that one section (for negative and zero numbers). Excel allows this type of number formats and if you set format like dd/mm/yyyy;[RED](#.##0); the positive numbers are visualized as dates, but negative numbers are visualized as numbers and their fore color is red.

Examples (including the final semicolons):

- ss;

- dd;

- dd/mm/yyyy;;

- mmm-yy;mmm-yy;_-* "-"??_-;_-@_-

When number format ends with N commas, the resulting number should be divided to 1000 N times. Instead, such commas are ignored. 

For example, if the format is #.0,, and the value of the cell is 12,200,000, the number should be displayed as 12.200.0

Images inserted in RadSpreadsheet are resized when the active sheet is changed. The set size is very small, making them almost invisible.

Workaround: Remove the two RadNumericUpDowns in the Picture contextual tab in the ribbon UI. They can be recognized by their bindings, to SetShapeWidth.SelectedValue and SetShapeHeight.SelectedValue respectively.

Steps to reproduce:
- Open RadSpreadsheet with the default Ribbon UI present.
- Insert image using the button in the Ribbon -> Illustrations -> Pictures.
- Add new sheet using the Sheet Selector (+) button, or change the sheet to another sheet
- Return to the initial sheet.

Expected: The image retains its original size.
Actual: The image size is changed to very small one.

If you set "[h]:mm" as a custom format to a cell which has time set to it the calculated value in the cell is wrong for the minutes. The minutes part is interpreted as months.

Value of a cell is visualized outside of the cell boundaries, or the value is clipped and partially visible, when the cell is updated (from code-behind), while being in an inactive worksheet, and is referenced by another cell from the active sheet.

Workaround: get a value of some cell in the active sheet and set it again to the same cell.

The issue is reproducible after the official release of Q1 2015.

Borders can overhang 1 px from the corresponding cells. The issue is reproducible only on some zoom levels, and is most probably related to WPF layout rounding. The issue is mostly visible when borders are missing. 

On different zoom levels, different borders are hanging.

Check how the performance can be improved in this scenario. The StyleGallery is taking much time to load, the GetUsedCellRange method is called multiple times.

This behavior happens at a specific width of the cell's Column. Using different VerticalAlignment (not Bottom) would workaround this issue.
