I have been struggling for this issue for the last one month. Please Help me out. I have a WPF datagrid (datagrid1) in which i am populating a datatable its working fine, in the same UI i have another WPF datagrid (datagrid2) which is to be populated as the mulitple rows selection from the first datagrid1 , how can we do this? Main problem is i want to bind the rows which are selected (multiple) how do i do? Help Me out please.

<DataGrid Name="dataGridSearchResults" 
          FontWeight="Normal" AutoGenerateColumns="False" 
          IsReadOnly="True" 
          ItemsSource="{Binding SearchResults,Mode=Default}" 
          SelectedIndex="{Binding SelectedIndexSearchResults}" 
          SelectionMode="Single" Margin="1,0,0,0" 
          Height="174" GridLinesVisibility="None" >
   <DataGrid.Columns>
        <DataGridTextColumn Header="RFC ID" Binding="{Binding RFCID}"></DataGridTextColumn>
        <DataGridTextColumn Header="RFC Title" Binding="{Binding RFCTitle}"></DataGridTextColumn>
        <DataGridTextColumn Header="RFC Revision" Binding="{Binding RFCRevision}"></DataGridTextColumn>
        </DataGrid.Columns>
</DataGrid>`

You just have to bind the ItemsSource property of your second datagrid to the SelectedItems property of your first datagrid : 

<WPFToolkit:Datagrid x:Name="dg1" ItemsSource="{Binding MySourceFromDatabase}" SelectionMode="Extended"/>

<WPFToolkit:Datagrid x:Name="dg2" ItemsSource="{Binding ElementName=dg1,Path=SelectedItems}" />
