NullReferenceException while changing DataRows in group

[User (Old forums)]

#14347 |

I want to change one cell value in all DataRows of one group.
Because this cell is the one by which the grid is grouped, the group should disapear and a new
group should be created.

But somehow I get a NullReferenceException here.

Any ideas?

Do you have an example code of how you’re currently trying to change the value(s)?

I think I’ve found a solution or at least a workaround for this.
I will some code later.
