I think this idea is a mistake that will cost you a lot of time and energy and never look "right." Why not have the selection in the ComboBox pop-up, or make visible, the TreeView (if it's not visible).

Another idea would be to use cascading nested menus to present the hierarchy; imho, that's more achievable.

Hi Fakeer, I'm happy to share my ideas, as comments; but, I am here to teach programming; I'll be happy to assist you when you start experimenting and implementing your UI elements, as you post specific questions, and code, related to your work in progress.

By the way, I don't work in ASP.NET; so, I have no experience with what may be the unique aspects of the Controls provided there compared to Windows Forms.

If your UI in ASP.NET permits you to effectively show/hide a TreeView, then I'd encourage to pursue that. I have implemented dynamic nested menus created from a Tree structure in Windows Forms, but found such a UI was not effective if it presented more than three, or four, levels of "nesting."

You could also consider showing/hiding ComboBoxes on-the-fly as a way to present a choice in a hierarchy.

I suggest you create simple projects using ASP.NET where you can isolate, and focus on, only the different UI approaches you want to isolate. imho, prototyping early is always a good thing.

cheers, Bill

How many levels of nesting your treeview will have?

If 2/3 level, can we use 2/3 drop downs?

Or in ASP.Net you can create in CustomControl

Do you need something like this?

XML

<Grid>
    <ComboBox x:Name="comboBox" HorizontalAlignment="Left" Height="41" Margin="62,44,0,0" VerticalAlignment="Top" Width="347">
        <ComboBoxItem>
            <ComboBoxItem.Template>
                <ControlTemplate>
                    <TreeView Height="auto">
                        <TreeViewItem Header="Level 1 A" />
                        <TreeViewItem Header="Level 1 B" IsExpanded="True" >
                            <TreeViewItem Header="Level 2"/>
                        </TreeViewItem>
                    </TreeView>
                </ControlTemplate>
            </ComboBoxItem.Template>
        </ComboBoxItem>
    </ComboBox>

</Grid>
