    <p>Disclaimer: I have been doing CRUDs for I don't know how long, but I'm just starting now with my first winforms app.<P> So, some mixed ideas:<p> In our current system (written using Centura/Gupta) we use a MDI-like approach. I think it is important to allow the user to start working on a new record without forcing him to close his current work, so a list of open windows is always displayed to allow quick switching between the different forms. Example:<p> <a href="http://www.pingmbh.de/download/medi01.png" rel="nofollow noreferrer">alt text http://www.pingmbh.de/download/medi01.png</a> List of open windows in the lower left. Also this system makes it possible to open one record from inside another, e.g. open a customer, show the orders of this customer, doubleclick on one of his orders to open it and so on.<p> Now about winforms: After doing some research I deceided against MDI and instead use a Form containing some SplitContainers. One of this container panels shows a list of open windows, another shows the current form. Since I did not find a way to show a Form in a panel, the forms are realized as user controls. The main form keeps track of the opened windows and displays them in the window list. If the user clicks on a window in the list, or opens the same record from somewhere else in the programm, the appropriate panel is brought to the front. Picture of a work in progress: <a href="http://www.pingmbh.de/download/pdp_progress.png" rel="nofollow noreferrer">alt text http://www.pingmbh.de/download/pdp_progress.png</a><br> Consider to seperate the selection of existing records from the editing of these records, i.e. show the existing records in some kind of table (like a gridview) with filter and search capabilities and let the user doubleclick these records to edit them. <p> I noticed on your screenshot that you have buttons for "Insert" and "Update". Is this for creating new records and saving existing records? I think a better approach is to give the user a "New" button, then open a form that has "save" and "cancel" buttons. The user may not allways remember if he started to edit a new or an existing record. <p> The selection screen btw is a good place for the "new record" button.<p></p>

    1. COAs for the Insert/Update, Yes the idea is that if they have the appropriate permissions they can make changes and commit them from that screen. Thanks for the input.

    2. COAlso, do you know of a reason that I should use UserControls over embedding my forms in panels? I have seen user controls come up a couple of times but I honestly do not know what I would gain using them over embedded forms...?

    3. COAFAIK you simply can not embed forms into panels. But then I consider myself a winforms-newbie

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.
