    <p>a tab control would give you a separate set of panels. Its the obvious way to do it, but if you want to overlay panels and control the visibility you can, and its fine. I have a content viewer that displays either images or text depending on the mime type of the content, and that context switching occurs without user interaction, so it makes sense there to put the image control on top of the textbox and set it visible if the mime type is image/jpeg. Where a user is going to make the choice tho, I would use a tab control. </p> <p>I assume you are using the visual ui to add controls. you can just drag a tab control to your form and it should by default appear with 2 tabs defined. You can add more in properties my modifying the tabpages collection. That's where you would also rename them to reflect your choices (profiles, chats). drag the tab control up where you want it on the form and size it appropriately, or dock it to fill the form. drag 3 panels into the first tab, then click on the 2nd tab, and drag 3 more in there. then proceed as you would have. When the user clicks on the chat tab the tab control will manage the view - hiding the first tab and its 3 panels. Of course clicking the first tab would make that tabPage visible again. no need for you to code anything.</p> <p>I'll just add that I don't understand the design of having 3 profiles visible, and 3 chat history's. Unless your users are going to be limited to 3 friends. I would think you would be better off using a listbox for friends names on the profiles page, with a single profile panel that just filled the profile controls based on which friend is selected, and then the same list on the chat page, with a single chat panel that loaded the history into the textbox based on which friend was selected. That way you can have all the friends you want :) </p> <p>and for completeness i'll suggest one more way, why should the user have to switch between tabs to view a users profile or chat history when you can provide them both in a single tabPage? You could programmatically create a new tab for each user and on that tab have their profile panel on the left, and their chat history on the right. Less context switching = better user experience. The tab control will allow you to scroll for tabs that don't fit on the form automagically(tm). </p>

    2. CO@John: Thanks for sprinkling in the extra UI suggestions; gave me a couple of new ideas. My example in the question was just an illustration that I thought would make it easier to ask the question. The end-application isn't exactly just a chat/profile application.

    3. COAlso, update: I've begun building the tabcontrol-based layout and it seems fairly easy so far. Next step is to put in dynamic/programmatic addition of new tabcontrols!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
