I have a strange performance issue on WPF2007 vol2 with xamDataGrid.
If I assign an untyped DataSet with just 40 records to a grid, and the grid previously has only 1 or 2 rows displayed, then it takes almost 2 seconds to display the grid with the new data. But if I now assign a dataset with 1,000 records to the same grid which is now displaying a full page of data, it displays in 0.1 seconds! It seems that if the xamDataGrid has a largely empty screen performance is much slower when you then display a full screen of data.
Is there a solution to this problem ?
I also find grouping takes several seconds, as does expanding a hierarchical node. Winforms, on the other hand, is instant - and this is progress ?
I think the issue might be more related to resizing. I find if a grid is initially small, then resized large, the initial resize is slow and jerky as more rows/columns become visible. I have attached the sample solution demonstrating this - see SlowResizeOfGrid.zip. This is using the most recent 7.2 release.
Thanks,
Andy.
