Hi,

I have a wpf datagrid with many rows, each row has some specific behaviors like selection changed of column 1 combo will filter column 2 combo, and what is selected in row 1 column 1 combo cannot be selected in row 2 column 1 combo, etc...

So I am thinking of having a view model for the main datagrid, and another for each row.

Is that a good MVVM implementation? It is so that I can handle each row's change event effectively.

Question is, how do I create "each row" as a user control view? within the datagrid.

I want to implement something like this:

        <TreeView
        Padding="0,4,12,0">

        <controls:CommandTreeViewItem
            Header="Sales Orders"
            Command="{Binding SelectViewModelCommand}"
            CommandParameter="Sales Orders"/>          

    </TreeView>  

Where instead of a TreeView I want a datagrid, and instead of controls:CommandTreeViewItem a datagrid row in WPF.

Thanks in advance.
