Column Headers on every page | Infragistics Forums

Hey Guys,

I hope this can help you all out. I have a method that you can use to manually create a Report object by walking the WebGrid. Unfortunately, having the Column Headers repeating on each page is not possible through interacting directly with the WebGridDocumentExporter or through the way it exposes the Report objects from its various events (because it is too late in the cycle).

In order to obtain this higher level of granular control, you can always create the Report from scratch. You can also have alot of fun working with the classes to completely customize your Reports.

Try this code out in your applications and feel free to modify it as needed.

This method will take your WebGrid and create a Report that uses ITable to represent your Columns and Rows. Column headers will be repeated on every page thanks to the Header.Repeat = true; property setting (see code below).

Feel free to use and hack this code as you see fit. Enjoy!
