Referencing a cell's data without throwing an exception!
I have a DataGridView in which one of the checks I am trying to use is when the cursor is in the current cell, I need to check the value of the previous cell in the same row, however, when I try to do this I get the infamous "Object reference not set to an instance of an object" error.
I have attached the KeyUp Event in which this error is occurring. I have the line of code highlighted in yellow where this error occurs. KeyUp-Event.docx
