I have the following code The grid view <asp:GridView runat="server" ID="gdvPersons" AutoGenerateColumns="false" onrowcreated="gdvPersons

问题 I am creating a website where our customers can order parts directly from us. I have a datatable setup and when users click a button it adds a quick detail of the order to a gridview.

问题 Any ideas on how I can acheive 'Hierarchical' gridview? Basically I want when the user clicks on the '+', i "expand" and insert new rows without a full page post back.

问题 I have a datagrid in which i manually specify the columns (AutoGenerateColumns="false"). I'm using MVVM and I would like to bind the column header (the text) so that I get it from my ViewModel.
