Datagrid WPF: Bind datepicker in AutogeneratedColumns

I have autogeneratedcolumns datagridgrid. This is my xml code for defining a datagrid:

<DataGrid AutoGenerateColumns="True"  HorizontalAlignment="Stretch"  Name="dataGrid1" VerticalAlignment="Stretch"  
              AutoGeneratingColumn="dataGrid1_AutoGeneratingColumn">

Now, I am scanning each column and if column type is equal to System.DateTime, I want to add a datepicker with selected value equal to the value in the cell:

private void dataGrid1_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
    {
        // Modify the header of the Name column.
        if (e.PropertyType.ToString() == "System.DateTime")
        {
    e.Column = new System.Windows.Controls.DatePicker();
     }

    }

But when I do this I get this error: Cannot implicitly convert type 'System.Windows.Controls.DatePicker' to 'System.Windows.Controls.DataGridColumn' Any ideas how to solve the problem? Thanks in advanced.

You can have 2 DataTemplates as:

<DataTemplate x:Key="dueDateCellTemplate">
            <TextBlock
            Text="{Binding DueDate}"
            Margin="5,4,5,4" />
</DataTemplate>
<DataTemplate x:Key="dueDateCellEditingTemplate">
            <sdk:DatePicker 
            SelectedDate="{Binding DueDate, Mode=TwoWay}" />
</DataTemplate>

Then You can edit your column on check as like :

private void dataGrid1_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
  {                
           if (e.PropertyName == "System.DateTime")
            {
                // Create a new template column.
                DataGridTemplateColumn templateColumn = new DataGridTemplateColumn();
                templateColumn.CellTemplate = (DataTemplate)Resources["dueDateCellTemplate"];
                templateColumn.CellEditingTemplate = (DataTemplate)Resources["dueDateCellEditingTemplate"];
                e.Column = templateColumn;
            }            
  }
