you need add ivalueconverter change string object datetime. this.

public class stringtodatevalueconverter : ivalueconverter     {         public object convert(object value, type targettype, object parameter, system.globalization.cultureinfo culture)         {             return datetime.parse(value.tostring());         }         public object convertback(object value, type targettype, object parameter, system.globalization.cultureinfo culture)         {             throw new notimplementedexception();         }     }

of course, want implement form of validation logic, i've excluded sake of simplicity.

the markup...

<window x:class="wpfapplication4.mainwindow"         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"         xmlns:d="http://schemas.microsoft.com/expression/blend/2008"         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"         xmlns:local="clr-namespace:wpfapplication4"         mc:ignorable="d"         title="mainwindow" height="350" width="525">     <window.datacontext>         <local:viewmodel />     </window.datacontext>     <window.resources>         <local:stringtodatevalueconverter x:key="converter" />     </window.resources>     <grid>         <textblock grid.row="0" grid.column="2" horizontalalignment="right" margin="25,5,0,0" text="{binding alerttimestamp, converter={staticresource converter}, stringformat=dd mmm yyyy hh:mm:ss tt}"></textblock>     </grid> </window>
