Nattable with "horizontal tree" structure [message #1735305]

Hi,
I am looking for a possibility to present a matrix for a Tree-Structure. Expandable vertically and horizontal (dynamically changing the column number). So basically the row header group and the column header group should be presented by a tree where the column tree must obviously be rotated by 90°.

Does anybody know if this is feasible with Nattable?

Thanks in advance
Thorsten

I don't really understand what you are trying to achieve. As you already noticed dynamically showing columns is possible, e.g. using the ColumnGroupHeaderLayer with the ColumnGroupExpandCollapse layer. What you mean by "rotated by 90°" is not clear to me. If you only need to rotate the text, well that is simple. If you need to move it somewhere else, well that wouldn't work with the ColumnGroupHeaderLayer, but you could implement your own layer that triggers the ColumnGroupExpandCollapse function in the body. That is basically how it works.

Technically it should be possible to implement something like you request. But there is surely no out-of-the-box solution available.

Just to finish this up. I have created a HorizontalTreeLayer by transposing the behaviour of the TreeLayer and all relevant Painters, Commands and Handlers.
Together with the respective IDataProviders this works like a charm.

Again I have to say that I am quite impressed about the power and ease of use of Nattable.

Great work!

Regards,
Thorsten
