I have a problem. But to make a Long story short, ill just say what i want to accomplish.
I have a Datagridview, I can re-arrainge the data inside of it, by clicking the column headers to "auto-Sort" my data. But now i insert another database into the datagridview, (After clearing it of course). But NOW when i want to use the auto-sort funcion it throws a "null Reference Exception". I can see that little arrow on the column header didnt disappear when i cleared the datatable and gridview.
I dont know of any Reset-datagridview-methods, so the only solution i can see is Disposing the Datagridview and re-opening it, but i dont know if that is possible.
Thank you =)
