I have a datagrid that is populated with data. If the operator scrolls off to the click on a field that is off to the right (not initially displayed on the grid) ---- then the operator does something that needs to repopulate that data with a different set of information --- an error is generated. The new data consists of the same fields, but just it is just pulling in a different set of data. If the operator does not scroll off to the side of the grid but refreshes the grid with new information, the error does not occur. If the operator scrolls off to the right, but does not click on a cell, an error does not occur. I have included the code that binds data to the grid and displays it. I've narrowed down that it is stopping on the "dgtabhistory.DataSource = mydataview " statement where I bind the data to the view. The error says: "An unhandled exception of type 'System.ArgumentException' occurred in system.windows.forms.dll
Additional information: Column 'Strategy ID and Desc' does not belong to table ACTIVITYHISTORYGRID." The column name may change --- it kind of depends on how far over to the right I scroll on the grid and which cell I click on.

Does anyone know about a possible bug with VB.net? Or am I missing something?? Is there a special command(s) I need to do before I bind new data to a datagrid?

I found the problem. I had to add dgtabhistory.DataSource = nothing before the dgtabhistory.DataSource = mydataview.
