I have never used Infrigistics controls before.  I inherited a web page that uses the UltraWebGrid control.  It is very slow at this point and I was hoping some of you can help me speed things up.  Here is my aspx code:

<igtbl:UltraWebGrid ID="UltragridPres" runat="server" Width="1500px">

Like I said, I have never used these controls.  Presently, it takes about 90 seconds to load the grid.  Is there anything I can do to speed up loading this grid?
