I am having two issues with my datagrid. First, my column headers are not displaying.
Second, the grid runs and displays correctly (except the headers) the first time. When the grid runs for the second time I get an error
An unhandled exception of type 'System.ArgumentException' occurred in system.windows.forms.dl
Additional information: Cannot create a child list for field Additional
The code is below. Does anyone see the error
Thanks in Advance

One problem solved! I can't believe I forgot to add the style.
Anyway, the second error is still coming up.
Any Ideas
Thanks

Hi,
Try deleting this line. You shouldn't need to set the datamember if
you are binding to a dataview.
DataGrid1.DataMember = "Additional"
