I noticed that I can't select the NxCheckbox as an InplaceEditor in the NextDbGrid.

The code shows that the NxCheckbox doesn't share the same ancestor as the other NextEdit controls, so it looks like it's not possible to do this without rewriting the checkbox.

If you add a TNxVirtualcolumn to a NextDbGrid then you will get access violations whenever you forget to check if the column you want to use is an actual TNxDbColumn as the TNxVirtualColumn don't have the same ancestral-class ...

The column-designer for the grid also allows you to add this TNxVirtualColumn even though it is incompatible with this grid.

Is there a way to use multi-select in the grid without having to set RowSelect ?
I could do this in the Delphi grid.

I noticed that the design-time editor for columns can cause 'List index out of bounds'-errors.

This only happens if the grid is placed in a frame and the form containing the grid is opened as well.

If I close the form which has the frame in the Delphi IDE the problem is gone and I can edit the grid-columns as normal.

I've been getting a lot of unexplained access violations which appear to trace their origin to the line containing FreeAndNil(FEditor) in the destructor for TNxCustomColumn.

One thing I noticed while debugging is that the inplace-editor I had assigned to that column got destroyed before the column itself.
It's as if having assigned an inplace-editor to the grid is enough to cause problems.

It might be important to know that I have all added columns design-time and that I am not relying on the 'auto-create'-column feature of the grid.
Also AlphaSkins-component is used to provide a skin.

I've had no luck in creating the same situation in a demo-program.
