title: Binding to DataGridTemplateColumn
body: <p>I have a User table and I have a foreign key of this table from a Book table. the FK is ProxyResponsibleUser_ID. when I use DataGridTextColumn in my DataGrid anything is OK but now I want to use DataGridTemplateColumn to display the FullName column from User table for corresponding  user with ProxyResponsibleUser_ID. I get an error since DataGridTemplateColumn does not have a Binding property. </p>
  
  <p>So, by which property of DataGridTemplateColumn will I  bind the ProxyResponsibleUser_ID?
  Thanks in advance.</p>
  
  <pre><code>&lt;DataGridTextColumn x:Name="securityConfigurationNameColumn" Binding="{Binding Path=SecurityConfigurationName}" Header="Security Configuration Name" Width="*" /&gt;
  &lt;DataGridTemplateColumn x:Name="proxyResponsibleUser_IDColumn"   Binding="{Binding Path=ProxyResponsibleUser_ID}" Header="Proxy Responsible User ID" Width="*" &gt;
                  &lt;DataGridTemplateColumn.CellEditingTemplate&gt;
                      &lt;DataTemplate DataType="{x:Type domain:User}"&gt;
                          &lt;TextBlock Text="{Binding FullName}"/&gt;
                      &lt;/DataTemplate&gt;
                  &lt;/DataGridTemplateColumn.CellEditingTemplate&gt;
              &lt;/DataGridTemplateColumn&gt;
