一、WPF 2个datagrid之间同步进度条

页面代码

            <Grid DockPanel.Dock="Left" Width="400">
                <DataGrid Name="dgSource" VerticalScrollBarVisibility="Visible"  EnableRowVirtualization="False" ScrollViewer.ScrollChanged="DgSource_ScrollChanged" >

                </DataGrid>
            </Grid>
            <Grid>
                <DataGrid Name="dgTo"   VerticalScrollBarVisibility="Visible" EnableRowVirtualization="False" ScrollViewer.ScrollChanged="DgTo_ScrollChanged">

                </DataGrid>
            </Grid>

后端代码

   private void DgTo_ScrollChanged(object sender, ScrollChangedEventArgs e)
         {
             ScrollChanged(dgTo, dgSource, e);
         }

         void ScrollChanged(DataGrid dg1, DataGrid dg2, ScrollChangedEventArgs e)
         {
             if (e.HorizontalChange != 0.0f)
             {
                 ScrollViewer sv = null;
                 Type t = dg1.GetType();
                 try
                 {
                     sv = t.InvokeMember("InternalScrollHost", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.GetProperty, null, dg2, null) as ScrollViewer;
                     sv.ScrollToHorizontalOffset(e.HorizontalOffset);
                 }
                 catch (Exception ex)
                 {
                     MessageBox.Show(ex.Message);
                 }
             }
             if (e.VerticalChange != 0.0f)
             {
                 ScrollViewer sv = null;
                 Type t = dg1.GetType();
                 try
                 {
                     sv = t.InvokeMember("InternalScrollHost", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.GetProperty, null, dg2, null) as ScrollViewer;
                     sv.ScrollToVerticalOffset(e.VerticalOffset);
                 }
                 catch (Exception ex)
                 {
                     MessageBox.Show(ex.Message);
                 }
             }

         }

         private void DgSource_ScrollChanged(object sender, ScrollChangedEventArgs e)
         {
             ScrollChanged(dgSource, dgTo, e);
         }
