Repeating headers for TreeGrid printing

Technical Q&A
1

Hi there

I am trying to print a treegrid on multiple pages with repeating column headers on each page.

For listgrids this has been fine because I can create multiple smaller listgrids from the larger grid (getRange()…) and call getPrintHTML() on each of those. 1 Listgrid per page to get the repeating headers effect.

I would like to try something similar with treegrids. I found that I couldn’t create a bunch of smaller treegrids to hold the results from getRange(). But when i put the results from getRange into listgrids this did work.

The only problem with putting the results into listgrids is that the indentation on the tree column is lost.

I would like to somehow keep this indentation when providing the data to the listgrids. OR Is there a way to use smaller treegrids instead of listgrids, where these smaller treegrids will accept that certains parent rows might not be present?

We don’t have support for a partial tree with dangling parentless nodes, but you could easily created equivalent indent in a ListGrid just using formatCellValue() - use Tree.getLevel() to discover the indent level.

Thanks that’ll do nicely.
