I have problem with hierarchy expansion:
I have a Master Grid with 2 chilidren a the same level, One Children has another child.
In the last child i user template columns and i have a button to post data.
I'm able to refresh all grid from master to last child after postback but the last child is always closed even if the parentItem's expanded property is true.
i tried to expand the child in the pre-render, to use ExpandHierarchyToTop method, to fire the Expand event manually but it doesn't work.
i user LinqDataSource with it's selecting event, and i set the datasource ID programmatically to control when databind fires.
