Is there a way to display a dataview control with multiple level grouping on a custom web part, not using SPD.
Right now, I'm using SPGridView control but It does not support multiple level grouping. I'm querying the data from several lists.
I want something like this, or even more than 2 levels:
- Business Area I - Area A Item 1 Item 2 + Area B + Area C + Business Area II
But I'm afraid I have to use JQuery plugin or something else...
