Problem with combobox in datagridview
1.
I'm working with a datagridview which contains a databound combobox. The edit mode of the cells = EditOnEnter. When I select a comboboxcell for which no value has been selected yet, and I try to sort the grid on another column (in my case a text column), then I get the following error:
Value of '16' is not a valid for 'rowIndex'
Where 16 is the index of the row I've selected. The above problem doesn't occur when edit mode = EditOnKeyStrokeOrF2.
2.
If the selection mode of the grid = FullRowSelect (and edit mode = EditOnKeyStrokeOrF2), then my comboboxes are not populating. When selecting the combobox, then I also get the above error message.
3.
When I select a combobox, and enter the first character of one of the values in the combobox and click on enter, then the selection has been made and I move to the next comboboxcell. When I try to do this action again, I just move to the next comboboxcell, but my selection hasn't been made.
Are these bugs or am I doing something wrong?
