We are seeing that in some scenarios there is a much higher cost to re-bind the DataSource of a XamDataGrid.  It seems, based on profiling traces, that all the time is spent in RemoveLogical/VisualChild downstack from GridViewPanelFlat+GenerationCache…

I'm binding the XamDataGrid to a reasonably large number of records (~15k) containing about 50 fields of varying types. When I start grouping by more than one field, the grid chokes the UI thread and my application ends up totally unresponsive for up…

Hi

I have a grid with ~1200 rows and quite a few columns but in this case I have stripped them down to just 3. I have plugged y data source to the XamDataGridPerformance sample and the performance is fine. The issue I have is that the data needs to be…

Environment: Infragistics v10.2 & .NET 4.0

The grid has about 455 columns and 2000 rows. Of the 455 columns only 50 columns are made visible and the rest Collapsed.

Once the data is loaded, both vertical & horizontal scrolling is very sluggish …

This demo loads 30000 rows into the datagrid and the scrolling is not completely responsive.  What can we do to improve the performance?

Thanks.
