Data validation dialog buttons should respond to the Enter or Esc keys (Retry, Cancel).

Copy/Paste a shape and then an image leads to a wrong result. 

Steps to reproduce: 

1. Copy plain text from a plain text editor onto the clipboard -> Paste in Spreadsheet and the text is pasted OK.
2. Copy the image from another app onto the clipboard -> Paste in Spreadsheet and the "This information cannot be pasted" dialog is displayed.
3. Insert picture from file into spreadsheet -> image displayed in a shape.
4. Select and copy the shape.
5. Repeat step 1 => Copy plain text from a plain text editor onto the clipboard -> Paste in Spreadsheet and the text is pasted OK.
6. Repeat step 2 => Copy image from another app onto clipboard -> Paste in Spreadsheet and shape selected and copied in step 4 is pasted. => Not expected result.

Memory leak when opening a new window that contains a spreadsheet several times.

We have a problem creating an Excel file with Telerik.Windows.Documents.Spreadsheet. 
In our last release for our customers we used Telerik WPF version 22.2.613.40 (Spreadsheet DLL)

When calling the following line of code

m_Worksheet.Cells[m_CurrentRowIndex, m_CurrentColumnIndex].SetValue("111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111 111111111111111111111111111111111111111111111111111111111111111111111 111111111111111111111111111111111111111111111111111111111111111111111 111111111111111111111111111111111111111111111111111111111111111111111 111111111111111111111111111111111111111111111111111111111111111111111 111111111111111111111111111111111111");

the CellValueType is set to text and the Value is correct.

We have now switched our project to .NET 7 and Telerik WPF to version 2023.2.519.70.

We discovered that this line of code no longer works.

The CellValueType is now Number and the Value Infinity

Have you changed anything internally? How can we solve the problem now?

Slow performance with documents that contain many custom styles. 

A filter cannot be applied to the RadSpreadsheet when a sheet is protected even though the Filter option in the protection dialog is checked. 

The data validation error message box has an invalid size when shown multiple times

Defined names do not appear in the Name Box.

DataValidation of a list with defined names is not taking the source into account. As a result, values are not displayed as options in the cell drop-down list.

InvalidOperationException (Sequence contains no matching element) when editing a note.

If the Spreadsheet ribbon has a custom template which hides the Style Gallery, when the Styles collection is edited, a NullReferenceException is thrown. This is because the change causes changes in the Style Gallery while the template of the Style Gallery is not yet applied.

Searching with Ctrl-F in a sheet with many rows takes a long time.

The sheet navigation does not work with specific theme and document.

telerik:Label's Context is set to itself and is throwing an error while searching for a not existing 'Title' property within itself.

NullReferenceException when the document contains paragraph elements with no text. 

Fill down (Ctrl-D) is not working in a protected worksheet with an unlocked range of cells.

PrintPreviewControl throws NullReferenceException when it is in the GridView Print example. 

The cursor position is changed when one clicks in the middle of a formula. The cursor is moved to the end of the text. 

When certain files are imported, an exception with message" is invalid column name" is thrown.
