Hello,
I am looking for a way how to show the grid column headers in a hierarchical way (for example the top level would be year and lower level would be quarters then months and so on (as shown in attached jpg)).
The data I am trying to display are already flattened in my VM to the column header hierarchy lowest level - so only the lowest level acts as the "real" column headers. I just need the higher levels to be data-bound, displayed and aligned in the headers section.
Any pointer how to achieve this would be appreciated.
Thanks, Stefan

Thanks Vlad,
That is almost what I needed.
Would it be possible to use more than one level of grouping using the described technique?

Hello Stefan Dobrovolny,
It gets more complicated but I think it is achievable. Can you please attach a picture of the desired output so I can try prepare a small sample for you ?

Hi Pavel,
What I'd like to achieve is to having headers behave as they do in the OLAP grids:
I have the hierarchy (hierarchical structure) of items and I would like to show the hierarchy as the column headers.
The data inside the grid are "bound" only to the "leaves" of the hierarchy and any other logic is handled in code behind.
Best regards, Stefan

Hello Stefan Dobrovolny,
Ok , indeed this gets a bit beyond the capabilities of RadGridView. Actually there has been an increasing demand for such feature lately so we are planning either a new control ( kind of pivot grid) , or extending the current RadGridView to cover such scenarios.
As I said such behavior is achievable even with the current version of RadGridView, but the hierarchy-header logic should be manually implemented in a user control which later can be placed above the regular header. The code will be complicated and hard to maintain. In case you have fixed column widths and turn off the column resizing - this may simplify the code.
With these thoughts in mind I would recommend to carefully reconsider whether you want to go that way.
