I want to increase the width of the initial RowsFieldDropAreaControl. Its pretty much still there in the PivotGridPanel as part of the original template.  I added a ComboBox before the ColumnsFieldDropAreaControl and made that area bigger , and I want the RowsFieldDropAreaControl which is part of the PivotGridPanel to match that size. If I change the size of RowsFieldDropAreaControl say to width=300px or maxWidth=300 it doesn't work, it seems to be resetting this somehow.

Can you please provide a sample of the above. I have tried several different way to change this and it hasn't worked yet. Thanks for your help in advance.

Attached is snippet of where RowsFieldDropAreaControl is.
