I am more familiar with WPF but I am not sure what you mean by DataGridCell.IsReadOnly. Are you templating the column cell and then accessing the IsReadOnly like such: Entity Binding Main Object binding If that is not available you should be able to use the DataGridTemplateColumn and set up your own binding. Computers have been intelligent for a long time now. It just so happens that the program writers are about as effective as a room full of monkeys trying to crank out a copy of Hamlet.

I've solved it. The method DomainDataSource.DataView.Add() can do this . ^^

Thanks for that, but if I were you I would include vital information such as platform in future just so you don't get answers like mine.

It's WPF. When I was a coder, we worked on algorithms. Today, we memorize APIs for countless libraries — those libraries have the algorithms - Eric Allman

This[^] might give you some ideas.

...and this may help you out... ListBox Styles and Templates[^] Mark Salsbery :java:

VectorLight has a color picker[^] that you could use.

Mark has given you the "correct" answer here. All you need to do is override the ItemsPanelTemplate. There is no need to re-invent the wheel as other posters have suggested.
