If I make the DataGrid editable I can select from the drop down and it updates the Data Grid which I can show by scrolling the Drop Down List off the panel and back on and it is still changed at the same time the Drop Down List scroll bars just close the drop down list when you click on them.
If I make the Data Grid Un-editable the scroll bars begin to work but the editorDataField does not pass the update into the Data Grid and so it won't remember the changes. editable="true" Scrolling fails, Update works editable="false" Scrolling works, Update fails - Help!!
