xmlns:sys="clr-namespace:System;assembly=mscorlib"

 <TextBlock   Name="block" Text="{Binding Source={x:Static sys:DateTime.Now},  StringFormat='yyyy-MM-dd HH:mm:ss '}"/>

 <TextBox   Name="block1" Text="{Binding Source={x:Static sys:DateTime.Now},  StringFormat='yyyy-MM-dd HH:mm:ss '}"/>

Answer 1

This binding works using a TextBox and should be what you're looking for:

<TextBox HorizontalAlignment="Left" Height="23" Margin="0,260,0,0" Text="{Binding Source={x:Static sys:DateTime.Now}, Mode=OneWay,  StringFormat='yyyy-MM-dd HH:mm:ss '}" VerticalAlignment="Top" Width="120"/>

result:

Answer 2

this works fine when you set the Binding Mode in the TextBox to OneWay :

 <TextBox Grid.Row="1"   Name="block1" Text="{Binding Source={x:Static sys:DateTime.Now},  StringFormat='yyyy-MM-dd HH:mm:ss ',Mode=OneWay}"/>

this is due to the fact that the default Binding mode in TextBlock is OneWay and in TextBox is TwoWay
