The fix will be available in our next LIB release (v. 2015.03.1005).

Currently, only Workbook/Worksheet could be protected. Would be nice to expose a way to protect cells for scenarios in which only particular cells should be locked for modifications.

The item is duplicated. Please, find the approved public item at http://feedback.telerik.com/Project/143/Feedback/Details/145412

Add support for preserving and exporting the macros in a macro-enabled workbook.

When using the OpenFile command to open a document, you should be able to obtain the Name of the workbook in the WorkbookChanged event handler. 

Clicking the Find All button resizes the dialog to a smaller size and the buttons on the bottom are not visible. Closing the dialog and opening it again opens it with very large size.
No workaround at the moment.

Number formats like "[$-1010409]General" containing locale code and General keyword are not parsed correctly which results in interpreting them as number formats which have to replace the positive numbers with "General".

The AM/PM value is not shown in the cell when formatting a time value.

Steps to reproduce:
1. Insert some time in a cell in spreadsheet (22:20)
2. Apply it a custom format that contains AM/PM (e.g. "h:mm AM/PM")

Observed: The AM/PM format is missing
Expected: AM or PM should be shown after the time (image attached) 

Declined: The changes could be applied if the user presses OK button instead of pressing Enter key. A new feedback item is open where the issue is described: https://feedback.telerik.com/Project/143/Feedback/Details/212042-spreadsheet-custom-number-type-values-in-format-cells-dialog-are-not-applied-wh

Add support for formats which can present numbers with non-arabic numerals, for example:
- Bengali - [$-bn-IN,500]0
- Devanagari - [$-hi-IN,400]0
- East Arabic - [$-ar-SA,200]0
- Persian - [$-ar-SA,300]0
- Gujarati - [$-gu-IN,700]0
- Kannada - [$-kn-IN,B00]0
- Khmer - [$-et-EE,1200]0
- Lao - [$-lo-LA,E00]0
- Malayalam - [$-ml-IN,C00]0
- Mongolian - [$-mn-MN,1300]0
- Burmese - [$-my-MM,1000]0
- Oriya - [$-or-IN,800]0
- Tamil - [$-ta-IN,900]0
- Telugu - [$-te-IN,A00]0
- Thai - [$-th-TH,D00]0
- Tibetan - [$-bo-CN,F00]0

If you begin entering e.g. "=" in FormulaBar, the characters are not visible in dark themes. If the focus is in the cell it works as expected, if the focus is in FormulaBar, the Foreground is dark and cannot be seen on dark background. 

Workaround:
-  set the following style (add BaseOn if using implicit styles)

<Style  TargetType="spreadsheetControls:RadSpreadsheetFormulaBar" BasedOn="{StaticResource RadSpreadsheetFormulaBarStyle}">
            <Setter Property="Foreground" Value="White"/>
</Style>

Implement automatic completion of cell value based on the values typed above, in the same column.

When a row is removed through code and an image is created immediately after that in the same method, the UI does not update. The change is made in the model, but not visualized. If you scroll up and down the change is reflected in the UI.

The background should be stretched along with the item itself. It is currently with specified width.
Workaround: Modify the style and change the width of the tab item. A sample is attached.

Currently, changing the sheets performs heavy calculations on the UI thread. This does not allow to perform any other UI task and the busy indicator cannot be shown before all layers are rendered.

In MS Excel, the users have the option to specify that the data contains a header row. When this option is enabled, the first row of the column is not included in the sorted range. Implement this option in RadSpreadsheet as well.

Allow loading of dialogs (SpellCheckAllAtOnce and SpellCheckWordByWord) different than the default ones through MEF. 

Use-cases: set different Width and Height, hide buttons (e.g. AddToDictionary), etc. 

When the InsertFunctionDialog is opened and the "Go" button is pressed with many words entered in the search terms field, the performance is so slow that the application appears hanged.

This item is moved, because it is related to the RadSpreadsheet's model. You can find the corresponding item here: https://feedback.telerik.com/Project/184/Feedback/Details/255960-spreadprocessing-incompatibility-with-microsoft-excel-of-in-document-hyperlinks
