Datagridview cellvalidating not working
I’d rather code to do exactly what it says it’s doing. This has the added bonus of not firing when you have clicked outside of the checkbox area, but still falls perhaps under the same category of not being entirely clear to someone unfamiliar with this issue why this particular event should force the grid to exit edit mode.
After looking into the problem at some length, MSDN actually seems to offer the best solution right on their Cell Content Click event page. I like that it tells us very specifically what has happened to the grid at the point in time when the event is raised and handled.
Also, the drop down list will add / remove handlers so you can easily test out which handlers do what without having to specifically comment out lines of code.

Its not permissible to have the two selected to true, but they can both be false.
I wrote code in the cellvalidating event as follows. Data Grid View Cell Validating Eve nt Args) Handles Datagrid1.
Data Property Name = "Cell_2") Then If CBool(Datagrid1("Cell_1", e. I wrote code in the cellvalidating event as follows. Data Grid View Cell Validating Eve nt Args) Handles Datagrid1.
Cancel = True End If End If End Sub Say I checked just one checkbox Cell_1 to start, the code allows the change to be made. I press the sacep key after the e,cancel and the message and I get the same problem.
Any solution is going to involve using an event that definitely will fire to stop the Data Grid View from thinking it’s in edit mode.
This problem was also raised in a Stack Overflow Question which seemed to advocate for handling the method, thereby ensuring that the grid would evaluate whether or not the Cell’s value had, indeed, changed and fire the corresponding event appropriately I must admit, this works, but feels like more of a work around than a solution.
