Perfomance Issues Binding Business Object To Grid
posted

I have an an UltraGrid (version 10.1.2) which is bound to a BuisnessObject called BLPerson (actually I bind to a collection of BLPerson). BLPerson is a rich object and results in the UltraGrid having 61 bands which causes the grid to take a long time to display (up to a minute). Also even if my collection only contains 1 row it still takes about 10 seconds to display. I only need to show 4 of the bands in the grid so have tried a number of things with no luck.
1. Setting RaiseListChangedEvdnts=false
2. Setting Band.Hidden=true for the bands I don't want before doing the DataBind
3. Binding directly to the collection and binding througn a BindingSource
4. Setting MaxBandDepth

Ideally I would like to be able to bind to my colletion then remove the unwanted bands before displaying the grid but I don't think that this in an option.

Any help gretly appreciated

Thanks John

    Hi John,

    You can hide properties from data binding by using the [Browsable(false)] attribute on the property. So if your BLPerson object exposes a public colection property that you don't want to be recognized by the grid, place that attribute on the property and it will hide that band from the grid and from the DotNet BindingManager.
