I had the EXACT same problem. I never would have in a million years thought it had anything to do with the autosize property and therefore would have never found it (and probably would have just eaten the exception). Thank you very much!

I don’t know if this would help - I had the same problem but this is what worked for me. On my form I have 4 datagridviews for inserting and updating. Inside these datagridviews I have comboboxes and to populate the comboboxes I used the same datasources as my datagridviews. When updating the datagridviews I received a “System.Argument.Exception: DataGridViewComboBoxCell value is not valid” for each combobox inside the gridviews. I then created separate typed datasets as lookupdatasets for the comboboxes to populate them and my problem was solved.

Hi,

I have gone through all the settings whichever possible but I am unable to resolve same issue in application.

In my DataGridView there are 3 ComboBoxColumns. Out of which two are filled by Enum list and one from DataAdapter.
I pass Generic Class object as DataSource to DataGridView. Based on the values in this object I want those ComboBoxColumns values need to be selected and relevant DisplayMember has to get displayed.

I works only for 2 ComboBoxColumns which are filled with Enum List. But third combo shows ValueMember as DisplayMember and gives same error :

“System.Argument.Exception: DataGridViewComboBoxCell value is not valid”

What could be the reason for it?

Plz help me to solve this.

Private Sub DataGridView1_DataError(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewDataErrorEventArgs) Handles DataGridView1.DataError
If e.Context = DataGridViewDataErrorContexts.Formatting Or e.Context = DataGridViewDataErrorContexts.PreferredSize Then
e.ThrowException = False
End If
End Sub

Thank you very much for this clear and concise solution.

You have saved me hours of work also. I searched the web and also found a lot of unanswered questions, or errors about data types not matching.

But I found your solution fairly quick. So thank you for putting it out there.

I also found it frustrating that the error did not mention what event was causing this so could not tell where to put the error handling code.

p.s This was in Visual Studio 2008, so the problem has not gotten addressed by MS yet.

Thanks very much…

I could not find what the problem was while I never had made the relation between Autosizecolumnsmode and this errormessage “System.Argument.Exception: DataGridViewComboBoxCell value is not valid”
