Export to Excel

Description

This example demonstrates how to implement data export to Microsoft® Excel®.
A single Web page is used with a grid that outputs the same data in both Web and Excel modes. An event code is used to determine if Excel mode was specified via a URL parameter, and to set the appropriate content type. The code is also used to force up to 10,000 data records to be output in Excel mode.

Usage

Click on the "Export to Excel" link.

Steps to Recreate

1. Use the Grid Builder to create the employees grid that is based on the employees table from Intranet database.
   • On Step 4 select No Sorting.
   • On Step 5 select (No Theme).
2. Add the ToExcelLink Link control above the Grid and set its Default Value property to "Export to Excel", set the Preserve Parameters property to None and the Href Source property to the current page. Then add the Link Parameter with the following values: Data Source Type = Expression, Parameter Source = 1 and Parameter name = export.
3. Add the appropriate programming code to the Before OnInitializeView Page event and Before Select Grid event., as provided with the example.
4. Make cosmetic changes as needed by modifying the text and captions within the HTML.
