I have an advanced DataGrid
The dataProvider is an XMLList hierachData which I wrap in
HierarchicalCollectionView and supply it to the datagrid
At each subsequent refresh I change the source of my Hierarchical data
hierachData = new HierarchicalData();
hierView = new
hierView.filterFunction = filterData;
change the source
hierachData.source = tableMonData.elementHierarchicalData;//new
xmlList passed as a source to the existing dataProvider
The datagrid nodes collapse which is not expected for my feature.
Any help will be highly appreciated.
Never used/seen and ADG , but I'm sure its got something similar to the Tree where it keeps track of open items. There is plenty of information of how to keep a tree open during a data update , as long as the items implement IUID.
