I have a tab control with 2 tabs. the first has a telerik wpf gridview and the other has an out of the box msft datagrid.
when selecting the tabs the tab with the datagrid shows much faster than selecting the tab with the gridview. the datasources are exactly the same, both xaml views use the same viewmodel. the grids have the same columns and same resources. it seems that the gridview is calling IDataErrorInfo.Item on each of the items in the datasource when the tab is selected. Why? Is there a way to prevent this?
Thanks,
Nick
