Clicking on a calculated cell leads to the following error and crashes the demo:

Implement support for Comments functionality in the Spreadsheet.

Please follow the steps in the VS Designer:

1. Add a RadSpreadsheet and Office2019Dark theme:

2. Set the ThemeName for RadSpreadsheet to Office2019Dark:

3. Run the project. You will see that the row/column headers are not readable:

4. Stop the project and reopen the designer:

If you load the attached document in RadSpreadsheet and select the first cell A1, the yellow popup doesn't occur even though it is defined in the document:

Expected result:

Like in WPF RadSpreadsheet:

Like in MS Excel:

 

Import the attached sample file, right-click on the first cell and select Format Cell:

Expected result: correct cell style should be loaded as it is MS Excel:

Import the attached document:

Expected result: the cell B1 should be rendered with bold text as in MS Excel:

Import the attached document and zoom in/out:

Expected result: the whole text should be fully visible like in MS Excel:

Import the attached document in RadSpreadsheet:

Expected result: centered text like in MS Excel:

In Excel, the cursor changes to look like <-I-> when it is in the correct position to start resizing (column or row), and stays the same when the user is doing the resize - good visual feedback.

In RadSpreadsheet, we get a similar <-I-> cursor when in position to re-size, but this goes away (back to the normal pointer) whilst the user is re-sizing. The re-size operation works just fine, but I don't get the feedback whilst doing it.

Please refer to the two gif files illustrating the behavior in MS Excel and in RadSpreadsheet.

Add support for conditional formatting 

When the HorizontalAxisStroke is not specified, an error occurs during the document's loading.

 

ArgumentNullException is thrown when writing in a cell and focus another cell.

The protection set in the column style has higher priority than the one set in the cell format. This causes invalid behavior and some cells can be edited despite the protection. 

Exception when copying sheet with conditional formatting and opening it in RadSpreadsheet

Exception in the ValueContextResolver when importing a document that contains conditional formatting.

The row/column headers font is too large when the scaling is 200% or more. 

Text wrap does not work 

The filtering popup layout is not correct when a cell contains a very long text.

If I type a lowercase letter, the cell accepts the text and is placed in edit mode. If I type an upper case letter (holding Shift), nothing happens (no edit mode, no text displays in the cell).
