Datagrid - How to change the first 3 lines backgroundcolor

I have a datagrid, that has as its base an XML file. Depending on the data in the xml, the list gets sorted.

What i now want to do is change the first 3 lines background color, for example the first one red, second yellow and 3rd blue. after the 3rd it can all be just default white.

I cant find how to do this, anyone could help me out ?

thanx!

Most simplest way would be to handle the LoadingRow event of DataGrid and update the colors inside it.

private void dg_LoadingRow(object sender, System.Windows.Controls.DataGridRowEventArgs e)
{
    int index = e.Row.GetIndex();
    if (index == 0)
        e.Row.Background = Brushes.Blue;
     else if (index == 1)
        e.Row.Background = Brushes.Red;
     else if (index == 2)
        e.Row.Background = Brushes.White;
}

another way could be to retrieve the first three DataGridRow from DataGrid using the method described in this post. Then use the dataGridRow's Background property to change it's color

A more cleaner way would be to define a style for DataGridRow and use triggers to change the background color of particular DataGridRow. I am not sure if you have some criteria behind changing background color of first three rows or it is a hard coded requirement. If it is some criteria or value in DataGrid then you should go for Style based approach.
