ASP.NET Spreadsheet - UX Enhancements and UI Performance - (Coming soon in v16.1)

You'll be happy to hear that not only did we improve the performance of the DevExpress ASP.NET Spreadsheet control in the v16.1 release, but we also added some great features too. Let's take a look.

UX Improvements

The DevExpress ASP.NET Spreadsheet now ships with a number of improved UX elements including:

1. Custom header/footer when printing

A new dialog (within the page-setup dialog) gives you the ability to define a custom header and footer before printing your spreadsheet:

2. Mark a copied range using a dotted line

The Spreadsheet control will now use dotted lines when you select a range and copy it to the clipboard. This is a handy feature that you're likely familiar with in Microsoft Excel. It helps you to visualize what items you've just selected.

3. Fill handle

The Spreadsheet control now gives you the ability to use a fill handle to complete data in a series. You can even use it to fill in months and days:

4. Display/hide column and row headers

The Spreadsheet control also let's you hide (or show) the column and row headers.

UI Performance Improvements

Our ASP.NET Spreadsheet has been optimized so you can deliver Office-inspired solutions that are both visually stunning and perform at the highest possible levels. Performance optimizations have been applied across the board, at the server and during client rendering.

Take a look the following chart which shows the 'document load' and 'cell update' operations. You'll see how between v15.2 and v16.1, we've improved performance across all major browsers:

Azure Web Farms support

With this release, both the DevExpress ASP.NET Spreadsheet and Rich Text Edit controls can be used in web applications running on multiple Azure application servers.

Is it possible to pro-grammatically set an image path in the header so that a logo will come while exporting the excel?

Currently, it's possible to specify images using the server-side WorksheetHeaderFooterOptions ( This class has properties for the header and footer, which provide the WorksheetHeaderFooter.AddPicture ( method for adding images. For example, the following code will display different images for odd and even headers:

var workSheet = ASPxSpreadsheet1.Document.Worksheets.ActiveWorksheet;

workSheet.HeaderFooterOptions.DifferentOddEven = true;

workSheet.HeaderFooterOptions.EvenHeader.AddPicture(SpreadsheetImageSource.FromFile(Server.MapPath("~/picture.png")), HeaderFooterSection.Center);

workSheet.HeaderFooterOptions.OddHeader.AddPicture(SpreadsheetImageSource.FromFile(Server.MapPath("~/pictureLeft.png")), HeaderFooterSection.Left);

Take a look at this ticket:

In the T388836 ticket, this API is used to emulate borders in the header. You'll find a simple example there as well.
