Hi, With the normal DataGrid object, we can perform filtering by doing
grid.dataProvider = someArrayColection grid.dataProvider.filterFunction = myFilterFunction. However, with the advanceddatagrid, if the do, grid.dataProvider = someHierarchialData afer this statement, the grid.dataProvider variable will still be null, because internally in the setter of dataProvider, grid.dataProvider is never set of someHierarchialData is of type IHierarchialData, and therefore, I can't proceed with specifying the filter function. How is filtering supposed to be done for AdvancedDataGrid? Just a little more background on what I'm doing. I've successfully built a extension to the normal DataGrid so that given the grid an array of ColumnConfig object (each contains dataField, headerText, and filterType), a data grid will be created with the specified columns, and for each column, with its specified column-wide filtering built in. And now I'm trying to build a same grid that extends AdvancedDataGrid because we need the ability to display hierachical data. If anyone has built something similar, please share your thoughts. Thanks in advance. Regards, Ban
