DataGrid & CheckBox & RowDetails Visibility

Hello,

We are using a datagrid in the application, in the datagrid is a template column which contains a checkbox.

<DataGrid
                      Grid.Row="1" 
                      ColumnWidth="SizeToHeader" 
                      AreRowDetailsFrozen="True"
                      SelectionUnit="FullRow"
                      SelectionMode="Single"
                      IsReadOnly="True"
                      Sorting="DataGridSuspects_OnSorting"
                      LoadingRowDetails="DataGridSuspects_OnLoadingRowDetails"
                      ItemsSource="{Binding TheSource}"
                      SelectedItem="{Binding CurrentSelectedItem}">

So here is the code for the inserted CheckBox:

<DataGridTemplateColumn Width="SizeToCells" CanUserSort="False" CanUserResize="False"><DataGridTemplateColumn.Header><CheckBox IsChecked="{Binding DataContext.AllSuspectsChecked, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=views:View}}"/></DataGridTemplateColumn.Header><DataGridTemplateColumn.CellTemplate><DataTemplate><CheckBox IsChecked="{Binding Path=IsChecked, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"></CheckBox></DataTemplate></DataGridTemplateColumn.CellTemplate></DataGridTemplateColumn>

Now i have the following problem, as soon as the checkbox is clicked, the rowdetails of the datagrid are being shown.

But i want to prevent the rowdetails to be shown when the checkbox is clicked.

Any ideas how i could do that?

Thanks
