I'm using version 2008.1.  I've put together a preset that uses a gradient image for the header background, but it's important that the row expansion area be a solid color because the gradient images won't line up.  I've set this in my preset xml file... 

<RowExpAreaStyleDefault BackColor="White" BorderWidth="0px" BorderStyle="None"></RowExpAreaStyleDefault>

 In addition, I'm setting the styles in my InitializeLayout and InitializeRow events...

e.Layout.RowExpAreaStyleDefault.BackColor = System.Drawing.Color.White;

e.Layout.Bands[0].RowExpAreaStyle.BackColor = System.Drawing.Color.White;e.Layout.Bands[1].RowExpAreaStyle.BackColor = System.Drawing.Color.White;

e.Row.Band.RowExpAreaStyle.BackColor = System.Drawing.Color.White;

 However, no matter what I do the expansion area always adopts the header's background image.  Has anyone experienced this and remedied it?

 Many thanks!
