MasterPage.master consists of TreeView control which represents the list of Product's categories from NorthWind database.
ContentPage.aspx (based on MasterPage) consists of ObjectDataSource and GridView which displays products of selected category.
I would like to implement the following functionality: when a user select a category from TreeView, the GridView will show only the products of selected category.
If TreeView, ObjectDataSource, GridView are on the same page I could pass TreeView.SelectedValue in ObjectDataSource as SelectParameters[0] and there are no problems. But they are on different pages.
Give me an idea please. How can I achive this functionality?
