Cellvalidating datagridview example
Further, let’s say that you’d like to know as soon as the user has made a change to their selection.You might want to handle this for a number of reasons: to enable a save button, to change the appearance of selected items, to display a pop-up window, or to check for consistency against other choices.It turns out that this is trickier than it might seem and doesn’t work great out of the box from .
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. If the entered value is valid then the user can continue; if it is not valid then a error message can be produced, preferably using Error Text, and the user the cell. im not able to see the drop down menue of the combobox anymore (it was working fine before) the combobox is handelt by the event "Selected Index Changed" but this is not triggert anymore because i cant select anything. Greetings Holly The Cell Validating event has a specific role.What if someone is able to make a selection without a click event?
There seems to be a non-zero percent chance that this might fire incorrectly in some unforeseen situation.At first I was going to try to overcome this but then I don't really think I would write something like this and take away the functionality of the grid so I didn't bother with it.
