Yes. Without some context of what you environment you are trying to run this from, we can't really offer anymore help.

Ah sorry. I m working on visual studio 2010 ultimate, wpf/c# my datagrid are bound to some generic lists/datasets via simple itemsource-bindings. Thanks

There are a few ways you could achieve this. Without knowing how you are going to determine what triggers a new colour, I can't be any more specific other than to say that you could look at using a different item template using an ItemTemplateSelector, or you could use a DataTrigger to set the background colour. Either mechanism would suffice.

Okay, so wich property can i use for the Trigger or the Datatrigger? I mean is there something like "IsAdd" as a property? The only thing i found is "IsEditing" but i wanna the row change its background only if its a "new" row.

No. If you think about it, the data grid will treat all rows initially as a new row because it has no interaction with the database. You will have to provide some context for it to be able to figure out what a new row is; for instance, you might have an IsSaved property on your data. The key is to look at the data, rather than at the datagrid for the mechanism to add this.

Thanks Pete for the Assistance I already have some solutions for this based on my database.. but i dont wanna programm on all my classes/datasets/lists new property just to do this? thats why i m looking on a interface-way to resolve that, or maybe an independency function or something, i tryed for example this:

 void la2\_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
    {
        if (e.Action == NotifyCollectionChangedAction.Add)
        {

            emp.NewRowAfterFiltering = true;
           
        }
    }

NewRowAfterFiltering is a property wich i bound to the the datatriger of the gridrow to change background, but it didnt work.

Hi, You can get solution to your problem here to change the background of the added row in a data grid. Using this you can set specific appearance of the element via Appearance property. For instance, Grid.Appearance, Header.Appearance, Column.Appearance, Row.Appearance, Cell.Appearance. Visit here and have a look http://www.dapfor.com/Feature.aspx?id=custom_painting[^]
