View 2 RepliesIs it possible to add a button column to a datagridview and then remove a select group of these from rows without removing the rows themselves? That is, I want the ability to hide or remove these buttons in certain rows after certain actions have occured. I realized that I could simply delete the rows with these buttons, but I want to keep the data in these rows visible without the user thinking they have to use the buttons. I am assuming that I can also disable the buton in the desired rows as well.

So I have case statements grouped together here, but I have a few case statements that need extra decision based on a second variable after the original case is confirmed.

How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
