DataGridRow Foreground Color Change (Implement in MVVM)

Question

Hi,

Can somebody help me how to Change the color of a grid row text while loading. I know how to do in RowLoading event but no idea how in MVVM.

ClassItem item = e.Row.DataContext as ClassItem;
            if ((item != null) && (item.Note.Trim() == "Something"))
                e.Row.Foreground = new SolidColorBrush(Colors.Red);
            else if((item != null) && (item.1 == 0) && (item.2 == 0))
                e.Row.Foreground = new SolidColorBrush(Colors.Gray);
            else
                e.Row.Foreground = new SolidColorBrush(Colors.Black);

 

This i have done inside the LoadingRow event n it works fine.

Answer 1

u can use triggers for it:

<sdk:DataGrid AutoGenerateColumns="False" Height="213" HorizontalAlignment="Left" Name="dataGrid1" VerticalAlignment="Top" Width="408" >

            <i:Interaction.Triggers>
                <i:EventTrigger EventName="LoadingRow">
                    <i:InvokeCommandAction CommandName="{Binding LoadingRowCommand}" />
                </i:EventTrigger>
            </i:Interaction.Triggers>

        </sdk:DataGrid>

where i is xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
