Excel export of Telerik Kendo Grid with multiple detail levels

问题

I have a Kendo Grid with "multiple hierarchy" - two detail levels, like this:

• Main row
  • Details
    • Details of details
    • Some more details of details
  • Details
    • Details of details
• Main row
  • Details
    • Detail of details

Using this example I am able to export the "Main row" along with the "Details" row. But I am having a hard time exporting the "Details of details" row. I know it is possible using the approach in the example, but cannot seem to shuffle the code "the right way". Has anyone done this before, and can provide an example?

Thanks.

for anyone who is still looking for an answer to this, I was able to do an implementation of a 3-level export. It doesn't look the most pretty thing in the world but feel free to contribute and make it better. You can see the full implementation in this link. I also solved an issue where the export wouldn't work correctly for multiple exports.

Basically, you need to recalculate the master row indexes of each export every time you click expand in the master grid as the master row indexes are recalculated by Kendo. E.g. you expand row 4 (which will display a grid with 6 rows), then you expand row 1 (which will display a grid with 12 rows). When you do this, the index of "row 4" is updated with 4 + 12. So the new index of "row 4" is actually 16. You also need to be aware of header/footer rows if you want to export them or not.
