Add support for import and export of Excel Template files (XLTS) file format.

Currently, the customers can bind data only to the Workbook property of RadSpreadsheet. Allow them binding cell range to a data source.

At this point, the ribbon and the context menu are not localized out of the box and the users need to change the strings manually.

Add support for creating Tables and applying tables styles (predefined ones or custom).

Add support for text orientation (rotation). This is supported in the SpreadProcessing model.

ArgumentException when loading document with a FontDize less than 0.01. 

Among the other worksheet protection options, the customers can choose options like "Select locked cells" and "Select unlocked cells", enable or disable formatting options, insertion or deletion of different elements. These settings at the moment are not supported

In MS Excel, there is splitter that can be used to manually resize the formula bar. Also there is an arrow button which expands/collapses the formula bar to the last manually resized size. 

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.

When RadSpreadsheet is placed inside a data template and the Workbook property is bound, the binding fails. 

In the Convert() method of the debug converter, the proper value is set. However, an empty workbook is displayed in the view.

Number format not working when the decimal separator is set to comma.

Implement support for ChartSheet 

Please add support for cell content rotation.

 

I know that this is listed in the known unsupported features article, but just to be extra clear about what I am requesting, here's an example from Microsoft Excel

Hi,

Excel files containing charts, created in Excel are displayed incorrectly in Telerik spreadsheet control.

Excel view:

 

Telerik:

 

Line colors and dots are incorrect.

Excel file loaded in Telerik WPF demo app. Test file is attached.

Currently, the chart's appearance can be customized through the model API. Let the user be able to customize it using the UI.

Currently, to change the title of the ribbon, the users need to replace RadSpreadsheetRibbon with its XAML code. Expose a property allowing to do this change directly from RadSpreadsheetRibbon.

Currently, when the user is editing a cell and saves the document without leaving the edit mode first, the current value is not preserved in the saved document.
When pressing the File -> Save button in the ribbon, the Save dialog doesn't appear at all.
Workaround: Manually commit the change before saving. This workaround will also respect data validation:

This feature allows automatically to group ordered data in the table and calculate the subtotals of the values column in each group of similar items. The subtotals are included just after each grouped items.
