Hi everyone,
I?m having the following problem. I have a windows form application with 2 main forms, one of them is master form and the second one is the UNDO form, in the first form i input images in the datagridview based on the numeric key pressed, the second form is the undo form where i can delete the column that has the wrong value to continue inserting new values(Images). The problem is, the input works ok, but when i use the undo everything goes to hell, the grid loses it?s column names and after that inserting new values causes a lot of errors. Thanks every one for the help.
The form 1 code is bellow.
The form 2 code
