Each smaller DataTable is used as the data source for a different worksheet. If you bind the same data source to more than one worksheet, even under different names, ExcelTemplate will return the following error: This binding source named xxx was already added under the name yyy.

This approach is not compatible with ExcelWriter 3. It may occur to you to use a template with as many worksheets as necessary and append the optional modifier to all data markers on each worksheet. The assumption is that ExcelTemplate would ignore such data markers if there are no data bound to a worksheet. However, this assumption is not correct. The optional modifier has to do with the presence or absence of a column, not a row. ExcelTemplate ignores a data marker marked as optional if there is no corresponding column in the data source.

But if a data marker is mapped to a column in the data source, ExcelTemplate would attempt to populate all instances of such a data marker. If ExcelTemplateencounters a data marker and there is no data row left, its behavior depends on the type of data source. For a scrollable data source such as DataTable, ExcelTemplate would rewind the data source to the beginning, resulting in duplicate data. If you cannot use ExcelApplication, you would not be able to dynamically insert or remove worksheets at run time.

An alternative is to create multiple templates, each one containing a different number of worksheets. You can determine which template to use depending on the number of rows in the data source. Using DataReader for data retrieval is the simplest approach and has performance benefits. Using the continue data marker modifier involves performing additional processing on a worksheet after copying it and therefore is less efficient.

Binding data to individual worksheets, because the data source must be processed, can have a lower performance than the other approaches. The attachment contains a Visual Studio project illustrating the 3 approaches described in this article. Each of the approaches is contained in a separate method.

You must install ExcelWriter EE before running the demo. Share the post "How to populate XLS files with more than rows". Harlan Grove. Nick Hodge wrote JE McGimpsey. Me too Perhaps because when you get to that many rows the information should be in a database? If that many rows are being used the file has to be huge and cumbersome.

Jerry W. Per Gabriel Lozano-Mor? Ed Ferrero. Hi Gabriel, That looks fair enough. Bill Sharpe. David McRitchie. Hi Ed, That does not prove anything about how Excel stores information. What you are looking at is how Excel returns consecutive items in a range, as a logical arrangement, not as physical storage.

Hi David, Youre right, sorry for the sloppy wording.
