Question

I have a class X there are some data:

    private string yyy;

    public string YYY
    {
        get { return yyy; }
        set
        {
            yyy= value;
            NotifyPropertyChanged("YYY");
        }
    }

    private string color;
    [Browsable(false)]
    public string Color
    {
        get { return color; }
        set
        {
            color = value;
            NotifyPropertyChanged("Color");
        }
    }

I have ObservableCollection that keeps a list of class X

public ObservableCollection<X> xxx{ get; set; }

The list Contracting to DataGrid by binding as follows:

    <DataGrid x:Name="XXXX" ItemsSource="{Binding}" AutoGenerateColumns="True">
                </DataGrid>

The list is in the DataContext of the DataGrid,

I want the text of the first column in each row will be on color that I have of the class data? I will do converter that change from string to color but how do I define this in xmal?

You can use a DataGridTemplateColumn

<DataGrid ItemsSource="{Binding Items}" AutoGenerateColumns="False">
   <DataGrid.Columns>
        <DataGridTemplateColumn Header="FirstName" >
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding FirstName}" Foreground="{Binding Color}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
       <DataGridTextColumn Header="LastName" Binding="{Binding LastName}"></DataGridTextColumn>
    </DataGrid.Columns>
</DataGrid>

The conversion from string to color is implicit.
I know it is not strict MVVM but I would not lose sleep about having the Color property of type Color.
