Worksheet.ClearComments(CellRange) Method

Removes cell comments and simple notes.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v24.1.Core.dll

NuGet Package: DevExpress.Spreadsheet.Core

Declaration

void ClearComments(
    CellRange range
)

Parameters

Name Type Description
range CellRange

A CellRange object that specifies the cell range to clear.

Remarks

The ClearComments method removes cell comments and simple notes only. Cell content, formatting and hyperlinks remain unchanged.

To separately remove cell content, formatting, hyperlinks or clear a cell range completely, call the Worksheet.ClearContents, Worksheet.ClearFormats, Worksheet.ClearHyperlinks or Worksheet.Clear method, respectively. To delete entire cells from the worksheet, use the Worksheet.DeleteCells method (see the How to: Delete a Cell or Range of Cells example).

To clear cells, you can also use the range’s Clear* extension methods, defined by the RangeExtensions class (RangeExtensions.Clear, RangeExtensions.ClearContents, RangeExtensions.ClearFormats, RangeExtensions.ClearHyperlinks and RangeExtensions.ClearComments). These extension methods are accessible as methods of the CellRange object and called by using the instance method syntax.

Example

This example demonstrates how to clear worksheet cells.

Clear All

To remove all cell information (content, formatting, hyperlinks and comments), call the Worksheet.Clear method.

Clear Cell Content

To remove cell content only (value and formula), call the Worksheet.ClearContents method, or assign the CellRange.Value property to null or to CellValue.Empty.

Clear Cell Formatting

To remove cell formatting only, call the Worksheet.ClearFormats method, or apply the Normal style to cells via the CellRange.Style property.

To remove any hyperlinks contained in a cell or cell range, call the Worksheet.ClearHyperlinks method.

You can also get hyperlinks contained in the specified cell range via the HyperlinkCollection.GetHyperlinks method and remove them using the HyperlinkCollection.Remove method of the Worksheet.Hyperlinks collection. In this case, cell formatting is also cleared.

Clear Cell Comments and Simple Notes

To remove any comments and simple notes contained in a cell or cell range, call the Worksheet.ClearComments method.

You can also call the ThreadedCommentCollection.Remove or ThreadedCommentCollection.RemoveAt method to remove threaded comments. The CommentCollection.Remove or CommentCollection.RemoveAt method allows you to remove simple notes.

View Example

// Remove all cell information (content, formatting, hyperlinks and comments).
worksheet.Clear(worksheet["C2:D2"]);

// Remove cell content.
worksheet.ClearContents(worksheet["C3"]);
worksheet["D3"].Value = null;

// Remove cell formatting.
worksheet.ClearFormats(worksheet["C4"]);
worksheet["D4"].Style = workbook.Styles.DefaultStyle;

// Remove hyperlinks from cells.
worksheet.ClearHyperlinks(worksheet["C5"]);

Hyperlink hyperlinkD5 = worksheet.Hyperlinks.GetHyperlinks(worksheet["D5"])[0];
worksheet.Hyperlinks.Remove(hyperlinkD5);

// Remove comments from cells.
worksheet.ClearComments(worksheet["C6"]);

Comment commentD6 = worksheet.Comments.GetComments(worksheet["D6"])[0];
worksheet.Comments.Remove(commentD6);
