XtraGrid Cell Grouping

I am using XtraGrid in my app. I want to group some cells togethere and replace them with group name. Following is the description.

I above image I have selected few cells from Fir开发者_运维问答st columns. Now, from context menu when I will click on "Group", I will popup up a dialog for group name. Now here onwards the problem is.

1. I want to replace the cell containts logically with the group name. So in grid, for first column's selected cells, but while viweing it should appear as single cell. I have tried the cell merging feature of the xtragrid but that disbales the row selection feature. How to do this?

2. The grid shown above is bounded grid, so if I tried to do grouping for lets say Integer type of column, then how can I replace the group name which is string in integer column? is this possible in grid?

3. Can I add the unbounded column in bounded grid?

Please help.

Thanks, Omky

The question is 4 years old, but for those who googled this and have the same questions, you could try this:

1. You are right: To show cells of the first column with same content as a single cell use merging: Set Column1.OptionsColumn.AllowMerge to true. You can influence the merging behaviour using the Views CellMerge Event. As you do not have a continouos row in case of a merged cell, you cannot use RowSelect.
2. To use Grouping you can call Column1.Group(). To specify the value wich is taken for comparison you can specify the Column1.GroupInterval to e.g. Value or DisplayText. The Cells DisplayText can be customized using the CustomColumnDisplayText event.
3. As far as I know it is not possible to add an unbound colmn to a BandedgridView. Why would you want to do this?

Generally there is a fast and qualified support at DevExpress you can contact.
