First question: What are the top 10 features you using in the grid?

1 - Stationary Headers.
2 - Hierarchical Display.
3 - Sorting on client.
4 - Export to Excel.
5 - Merging of cells with common data.
6 - Grouping.
7 - Tweaking of cell contents as row is created (color, format of contents, etc)
8 - Adjustable column width and height based upon contents.
9 - Editing of existing data -- occasionally allow users to add new data but that's rare.
10 - WebCalcManager.

1. Sorting (I'd like to control what datafield it actually sorts on, like DataGrid/GridView do, but UltraWebGrid doesn't)

2.  Paging

I'd also prefer consistency with MS naming conventions.  I'm really tired of using .Hidden on the UWG instead of .Visible.

1) Freeze Header/Footer

2) Row selection

3) Sorting

4) Access cell values/column properties on client-side

5) add/update/delete (90% it's delete I prefer to use separate page for add/update)

BTW: consider use dialog control only for add/edit operations, it will greatly reduce the js code needed

6) AJAX (load)

7) Hierarcy databinding(please,please make it bind also to self-referenced table also)

8) Excel export

9) Very important ability for me: 

client-side state management: ability to add/update/delete rows on client only and after postback batch update

1) Paging

2) Sorting

3) Grouping

4) Hierarchy (dont think I spelt this right)

5) Column freezing

6) Grid exporting

Would like to see custom footer whereby I could add custom controls to it. For instance I would like to add a refresh icon at the footer of the grid.
