Using selected index to display only certain items

[handycam]

I have a datagrid displaying an xmllist. If I get the selected indices of this grid, how do I use that to display only those indices of the another grid?

For example:

xmllist1 = "A, "B", "C", "D", and datagrid1's dataprovider is xmllist1

The user clicks "B" in datagrid1, clicks a button and I capture datagrid1.selectedIndex.

xmllist2 = "1", "2", "3", "4".

I have datagrid2. i want to display "2" in this datagrid (the corresponding index item in the second list)

How do I do this?

I would add a filterFunction to the data provider of the second DataGrid. You can then use the selected indices to determine what must be displayed.

filterFunctions are transition effects...

Could you be more specific?

[dr_zeus]

The filterFunction property of an ICollectionView has absolutely nothing to do with transitions. When you set a DataGrid's dataProvider to an XMLList, it gets converted to an XMLListCollection, which implements ICollectionView. By setting a filterFunction on the dataProvider, you can specify which items are displayed in the DataGrid.
