    <p>I have worked with DevExpress's Quantum Grid for some time and their support form <a href="http://www.devexpress.com/Support/Center/" rel="nofollow noreferrer">http://www.devexpress.com/Support/Center/</a> is excellent. When you post questions the DevExpress staff will answer you directly. With that said, I did a quick search for you and found some relevant articles.</p> <p><strong>how to hide duplicate row values:</strong> <a href="http://www.devexpress.com/Support/Center/p/Q142379.aspx?searchtext=Duplicate+Rows&amp;p=T1|P0|83" rel="nofollow noreferrer">http://www.devexpress.com/Support/Center/p/Q142379.aspx?searchtext=Duplicate+Rows&amp;p=T1|P0|83</a></p> <p><strong>highlight duplicate records in a grid:</strong> <a href="http://www.devexpress.com/Support/Center/p/Q98776.aspx" rel="nofollow noreferrer">http://www.devexpress.com/Support/Center/p/Q98776.aspx</a></p> <p>Unfortunately, it looks like you will have to iterate through the table in order to hide duplicate values. I would suggest that you try to clean the data up before it makes it to the grid. Ideally you would update the code/sql that produces the data. If that is not possible, you could write a TcxCustomDataSource that will scrub the data when it is first loaded. This should have better performance because you will not be using the grid's api to access the data.</p> <p><strong>Edit</strong></p> <p>ExpressQuantumGrid will not automatically hide rows that look like duplicates because the user hid a column. See: <a href="http://www.devexpress.com/Support/Center/p/Q205956.aspx?searchtext=Duplicate+Rows&amp;p=T1|P0|83" rel="nofollow noreferrer">http://www.devexpress.com/Support/Center/p/Q205956.aspx?searchtext=Duplicate+Rows&amp;p=T1|P0|83</a>.</p> <p><strong>Poster</strong></p> <blockquote> <p>For example, I have a dataset which contains two fields ID and TXT. ID is a unique field and TXT field may contain duplicate values. So when the dataset is connected to the grid with all columns visible, the records are unique. See the image1.bmp. But if I hide the ID column then the grid shows duplicate rows. See the image2.bmp.</p> </blockquote> <p><strong>DevExpress Team</strong></p> <blockquote> <p>I'm sorry, but our ExpressQuantumGrid Suite doesn't support such a functionality, because this task is very specific. However, you can implement it manually.</p> </blockquote>

    2. COMy mistake, you need could write a TcxCustomDataSource. Basically, you extend TcxCustomDataSource and override the methods GetRecordCount, GetValue, SetValue, InsertRecord, AppendRecord and DeleteRecord. You don't need to implement them all if your source is read only. The documentation explains how to do this in greater detail. Good luck.

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.
