Checking Treeview from Datatable

[ekim12987]

I am creating a wizard like application that lets users select Provider/SubProvider combinations. I am populating a treeview from a datatable (called dtAllProviders). The treeview lets the user check all providers and subproviders. When the user clicks next I store all the selected values into a datatable(called dtSelectedProviders). When the User clicks back, I want to populate the treeview with dtAllProviders, then go through and check all the nodes for their corresponding record in dtSelectedProviders. I am really stuck on how to go through checking all the nodes. Any ideas or sample code is appreciated. Thanks.

Wouldn't it be better to use a single DataTable and add an extra Boolean column that indicates whether it's selected or not? Also, if you don't destroy your TreeView then there's no need to repopulate if the user presses the Back button.

That is a good idea just adding an extra column to the datatable. Thanks for the help
