Question

So let say I have a custom class:

Class Elements{

    int width;
    int height;
    bool isBol;

}

and in main I have something like:

Public class MainWindow{

    DataGrid dgv = new DataGrid();
    List<Elements> elem = new List<Elements() { 
         new Element(){width=100, height = 200, isBold = false}, 
         new Element(){ width=20, height=100, isBold = true}
    };

    dgv.ItemsSource = elem;

    dgv.Columns.Add(new DataGridTextColumn() { 
           Header = "Width", Binding = new Binding("width")}
    dgv.Columns.Add(new DataGridTextColumn() { 
           Header = "Height", Binding = new Binding("height")}

}

So it is just a simple table with 2 columns, width and height.

How would I make a row appear to be bold based on the bool value isBold? In my example above, the row 20×100 should appear to be bold in the table, where 100×200 should NOT be bold.

Can I do this?

I would use a DataTrigger in an Implicit Style

<DataGrid.Resources>
    <Style TargetType="{x:Type DataGridRow}">
        <Style.Triggers>
            <DataTrigger Binding="{Binding isBold}" Value="True">
                <Setter Property="FontWeight" Value="Bold" />
            </DataTrigger>
        </Style.Triggers>
    </Style>
</DataGrid.Resources>
