title: DateFormat in radGridViewDataColumn WPF
body: <p>I'm working on <code>WPF MVVM</code> application with <code>telerik</code> controls. I need to format one of the column to Date(<code>MM/dd/yyyy</code>). When i select a date from the calendar it works fine and after switching to next column the value is showed as <code>MM/dd/yyyy 12:00:00</code>. I dont need the time to be displyed along.</p>
  
  <p>//Code:</p>
  
  <pre><code>&lt;telerik:GridViewDataColumn Header="ApprvdDate" DataMemberBinding="{Binding ApprovedDate, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" DataFormatString="{}{0: MM/dd/yyyy}"&gt;                                                    &lt;telerik:GridViewDataColumn.CellEditTemplate&gt;
  &lt;DataTemplate&gt;
  &lt;telerik:RadDatePicker Name="ClrDatePicker" SelectedDate="{Binding ApprovedDate, Mode=TwoWay}" AllowDrop="True"&gt; 
  &lt;/telerik:RadDatePicker&gt;
  &lt;/DataTemplate&gt;
  &lt;/telerik:GridViewDataColumn.CellEditTemplate&gt;
  &lt;/telerik:GridViewDataColumn&gt;
  </code></pre>
  
  <p>where <code>ApprovedDate</code> is <code>string</code> object in the collection.</p>
  
  <p>The <code>DataFormatString</code> doesn't work. I tried changing many formats.</p>
  
  <p>Also tried as,</p>
  
  <pre><code>DataFormatString="{0: MM/dd/yyyy}"
  </code></pre>
  
  <p>which throws compilation error.</p>
  
  <p>Where i'm wrong?</p>
