#Remarks
With v17.2, DashboardControl uses the underlying dxTreeList instead of dxTreeList to visualize a Filter Elements Overview. This change can affect projects where ViewerApiExtensionOptions.onItemWidget… handlers are specified to customize the underlying dxTreeView widget.
The dxTreeView widget was replaced with dxTreeList for these reasons:
- dxTreeList has better performance when a large number of records is displayed;
- dxTreeList supports the search capability.
If necessary, you can return to the previous behavior and use the dxTreeView widget using the useLegacyTreeView property. The following code snippet shows how to do this:
JavaScript
window.onload = function () {
DevExpress.Dashboard.LegacySettings.useLegacyTreeView = true;
// ...
};
