Hello friends,

I am newbie in WPF. Currently i am creating DataGrid in WPF.

XAML CODE :

<DataGrid x:Name="DGMDStatus" AutoGenerateColumns="False" Height="440" HorizontalAlignment="Left" Margin="22,80,0,0" VerticalAlignment="Top" Width="800" BorderBrush="#FF000C21" BorderThickness="0.5" AlternatingRowremoved="#fff" HorizontalScrollBarVisibility="Hidden" CanUserAddRows="False" IsReadOnly="True">
	<DataGrid.Columns>
		<DataGridTextColumn Header="Status Id"  Width="200" Binding="{Binding StatusId}"/>
		<DataGridTextColumn Header="Status" Width="300" Binding="{Binding Status}"/>                       
	</DataGrid.Columns>
</DataGrid>

CODE BEHIND :

DGMDStatus.ItemsSource = dbcon.sp_StatusMaster_SelectAll().ToList();

So how can i check “Status” is null or not during databinding in code behind.
Please help me... Thanks.
