I am setting datasource of wingrid with custom object which is having hierarchical data. Grid is showing data in bands (3 bands).  But I am finding problem with 3rd band, when I expand 2nd band 3rd band doesn't paint. It paints when I click on any cell of 2nd band.

I also want to remove extra columns from band 2 and band 3. I tried with

e.Layout.Bands[ 1 ].Columns[ "ABC" ].Hidden = true;

InitializeLayout event of grid, but it it showing band 1 doesn't have any column.

I am using Infragistics  Version=7.2.20072.61.
