How to access data from another datatemplate in wpf?

I have 2 Datatemplates. One contain a grid , second one contain a button. I need to send command parameters of button as selected grid items.

How can i do this ?

<ObjectDataProvider x:Key="Datas" ObjectType="{x:Type ViewModel:UserControlViewModel}"></ObjectDataProvider>

<DataTemplate x:Key="SourceGrid">
<WPFToolKit:DataGrid x:Name="SourceDataGrid" ItemsSource="{Binding Source={StaticResource Datas},Path=SourceGridData}" CanUserSortColumns="True" GridLinesVisibility="None" IsSynchronizedWithCurrentItem="True" SelectionUnit="FullRow"></WPFToolKit:DataGrid>
</DataTemplate>

<DataTemplate x:Key="AddRemoveDataTemplate">
<StackPanel>
<Button Name="Add" Content="Add">
<Button.Command>
<Binding Source="{StaticResource Datas}" Path="AddCommand"> 
</Binding>
</Button.Command>
<Binding ElementName="SourceDataGrid" Path="SelectedItem"></Binding>
</Button.CommandParameter>
</Button>
<StackPanel>
</DataTemplate>

You could try to use a Binding with the RelativeSource property set to the FindAncestor mode and looking for a DataGrid object. However, I am not sure whether it will work in your scenario because I do not know how these DataTemplates are related to each other. Is the second DataTemplate used for the items in the DataGrid?!

Somehow, your design feels strange to me. Are you sure that you need DataTemplates in both cases? What exactly do you want to achieve?
