This might be basic question, however I am confused on some .Net Concpets.
I am trying to create a “Data Browser” in VB.net.

  • Similar to a Web Browser however each
    Tab in the Data Browser is a view of
    some Data (from a database or flat
    files) not a webpage.
  • The UI on each Tab is mostly the
    same.
  • A list Box (showing datatypes, etc),
    a TextBox (where you can create a
    filter), and a DataGridView, a
    DataSource Picker, etc.
  • The only thing that would change on
    each tab is that there could be a
    custom “Viewer”. In most cases
    (depending on the datasource), this
    would be the datagrid, however in
    other cases it would be a
    treecontrol.

From reading through the .Net documents, it appears that I need to Create a Custom Control (MyDataBrowser) Consisting of a Panel with all the common Controls (except the viewer). Every time the user says “New Tab”, a new tabpage is created and this MyDataBrowser Control is added, The MyDataBrowser control would contain some function that was able to then create the approriate viewer based on the data at hand.

If this is the suggested route, how is the best way to go about creating the MyDataBrowser Control

  • (A) Is this a Custom Control Library?
  • (B) Is this an Inhertited Form?
  • (C) Is this an Inherrited User
    Control?

I assume that I have to create a .DLL and add as a reference.
Any direction on this would be appreciated.

  1. Does the custom Control have its
    own properties (I would like to
    save/load these from a configuration
    file).
  2. Is it possible to add a
    backgroundworker to this
    customcontrol?

Thanks.

    You’ll want to make a UserControl.

    There is a walkthrough on MSDN that covers this in detail- Walkthrough: Authoring a Composite Control with Visual Basic.

    That being said, for your specific questions:

    1. Yes. It has its own properties (which you define).
    2. You can add a BackgroundWorker (or multiple ones) to a UserControl.

    As for deployment – typically, you’d have this in a class library (which makes a DLL), and reference that within your applications, but that is up to you. The UserControl can also just be added directly to your application.
