ExtendedDataGrid zooms out on binding ItemsSource

Hello,

when I bind a DataTable to the ExtendedDataGrid Control it seems like it zooms out (see picture)

My XAML-Code is following:
<ExtendedGridControl:ExtendedDataGrid 
                x:Name="EXDG" 
                ItemsSource="{Binding DT}" 
                DockPanel.Dock="Top" 
                ShowRowNumber="True" 
                IsReadOnly="True"
                
                RowHeaderWidth="17"  
                IsSynchronizedWithCurrentItem="True"  
                SelectionMode="Extended" 
                SelectionUnit="FullRow"
                FontSize="16" AreRowDetailsFrozen="True" GroupByHeaderText="Hier gruppieren!" IsTextSearchEnabled="True" 
                
                EnableColumnVirtualization="True"
                EnableRowVirtualization="True"
                ShowRowSummaries="True">
                <ExtendedGridControl:ExtendedDataGrid.FooterDataTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <TextBlock Text="RowsCount:" FontWeight="Bold"/>
                            <TextBlock Margin="3,0,0,0" Foreground="DarkGreen"  Text="{Binding ElementName=EXDG,Path=Items.Count}"></TextBlock>
                        </StackPanel>
                    </DataTemplate>
                </ExtendedGridControl:ExtendedDataGrid.FooterDataTemplate>
            </ExtendedGridControl:ExtendedDataGrid>
How can I suppress this behaviour?
