Drag the control from the VS toolbox to your form.
You can put three of them on your form, configure them so that they show the proper "part" of OPC model, each to do what you suggested, and then use event handlers to have the information flow from the first to the second and from the second to the third.
I wanted to know if it is possible with your toolkit to have a browsing dialog within a Windows Form Application instead of having it open in a separate window.
We are imagining three separate dialog boxes on the same form. The first browses for a machine, once found, the second browses for servers on that machine, and the third browses for the Channel, Device, and Tag on the server.
And we are hoping this can all be done in a single Winform.
