UltraGridBands out of synch with datasource UltraDataBands
posted

I have application that creates/removes rows and UltraDataBands in my UltraDataSource but very quickly my ultraGrid gets out of synch with the datasource. When I examine ultragrid.DisplayLayout.Bands collection it has multiple duplicated entries with the same key which I believe cause the problem. In my case I assign RowLayout to a band "Involuntary Assumptionnt" and it works fine the first time when there is only 1 grid band with that key in the DisplayLayout.Bands collection. After I remove and add back that band and rows several times I have multiple identical grid bands in DisplayLayout.Bands and RowLayout does not show up in the grid.

Here is a copy of my ultragrid.DisplayLayout.Bands view in the Watch window - notice identical bands  #3, 4 and 6

-        ultraGrid1.DisplayLayout.Bands.All    {Infragistics.Shared.IKeyedSubObject[7]}    object[] {Infragistics.Shared.IKeyedSubObject[]}
+        [0]    {Band 0}    object {Infragistics.Win.UltraWinGrid.UltraGridBand}
+        [1]    {Prepayment Assumption}    object {Infragistics.Win.UltraWinGrid.UltraGridBand}
+        [2]    {Involuntary Assumption}    object {Infragistics.Win.UltraWinGrid.UltraGridBand}
+        [3]    {Involuntary Assumptionnt}    object {Infragistics.Win.UltraWinGrid.UltraGridBand}
+        [4]    {Involuntary Assumptionnt}    object {Infragistics.Win.UltraWinGrid.UltraGridBand}
+        [5]    {MIAC RowLayout}    object {Infragistics.Win.UltraWinGrid.UltraGridBand}
+        [6]    {Involuntary Assumptionnt}    object {Infragistics.Win.UltraWinGrid.UltraGridBand}

I'm not sure if I'm doing something I'm not supposed to or it's a bug or what but I spent nearly a week banging my head against the table trying to figure this one out.

Please help.
