XLSB is binary format that should theoretically allow fast reading and writing to the file. 

With the current implementation, the Notes support only a rectangular shape.

Examples:

The button should always be active. 

The button:

When the Freeze Panes option is enabled and try to insert a new comment into the next cell on the left to the Freeze Panes separator the comment is deleted.

Add support for conditional formatting of cells - allow applying of rules used during visualization of cells to automatically apply formatting depending on their values.

Custom style is not applied to empty cells when applying to the entire row.

Workaround: 

Dim usedCellRange As CellRange = mobjValidationResultWs.UsedCellRange
For rowIndex As Integer = usedCellRange.FromIndex.RowIndex To usedCellRange.ToIndex.RowIndex
    For columnIndex As Integer = usedCellRange.FromIndex.ColumnIndex To usedCellRange.ToIndex.ColumnIndex
        Dim cell As CellSelection = mobjValidationResultWs.Cells(rowIndex, columnIndex)
        cell.SetStyleName("Common")

    Next columnIndex
Next rowIndex

Hello, 
we have an Excel export in our software that we solved via Telerik Spreadsheet. 
An exported Excel Table can also contain images. 
These pictures are inserted as shape objects. 
The Placement Property is set to xlMove (xlPlacement Enum) in Excel. 
If you now filter the data in Excel, the images remain and are not hidden. 
We therefore need a way of being able to change this Placement Property to the Value xlMoveAndSize
It would be very desirable if this option were made available in Telerik Spreadsheet as our customers urgently need it.

Hi,

Range name becomes incorrect after removing row in a spreadsheet.

Use case:

- Set range name to 'test' on cell A5

- Remove row 4 (option entire row)

Observed:

- Range name is still located on cell A5

Expected:

- Range name 'test' on cell A4. Similar behavior as in MS Excel

Can be reproduced using the Telerik WPF demo app.
