Dears,

hi

I am trying to bind the scroll of the datachart with the scroll of the grid

private void OnXamDataChartWindowRectChanged(object sender, RectChangedEventArgs e)
        {
            if (IsZoombarChanging) return;
            try
            {
                IsZoombarChanging = true;
                Range newZoombarRange = new Range
                {
                    Minimum = e.NewRect.X,
                    Maximum = e.NewRect.X + e.NewRect.Width
                };
                if (this.xmZoombar != null)
                {
                    this.xmZoombar.Range = newZoombarRange;
                }

               // this.pivotGrid.ScrollCellIntoView(this.pivotGrid.DataRows[0].Cells[size(newZoombarRange.Maximum)-1]);

                ScrollBar horiz = GetObject(pivotGrid, "HorizontalScrollBar") as ScrollBar;
                if (horiz != null)
                {
                    horiz.Value = size(newZoombarRange.Maximum);


                }


            }
            finally
            {
                IsZoombarChanging = false;
            }
        }

when i am using the ScrollCellIntoView , it working, but when using the horiz.value its not.

i want also to capture the horizontal scroll value of the grid, so that when i scroll the grid, i would be able to scroll the chart too.

Thanks,

   ScrollBar horiz = GetObject(pivotGrid, "HorizontalScrollBar") as ScrollBar;
                if (horiz != null)
                {
                    horiz.Minimum = e.NewRect.X;
                    horiz.Maximum = e.NewRect.X + e.NewRect.Width;

There is not scroll event but you can find the scroll bar from control and to listen for thier scroll event. Below is a snippet how to find the scroll bar. The names of the bars you can see from generic.xaml from pivotgrid control template.

 void PivotGridContainer_Loaded(object sender, RoutedEventArgs e)
        {
            ScrollBar vert = GetObject(PGrid, "VerticalScrollBar") as ScrollBar;
            ScrollBar horiz = GetObject(PGrid, "HorizontalScrollBar") as ScrollBar;
        }
 
        private DependencyObject GetObject(DependencyObject obj, string name)
        {
            DependencyObject child = null;
            int coutn = VisualTreeHelper.GetChildrenCount(obj);
 
            for (int index = 0; index < coutn; index++)
            {
                child = VisualTreeHelper.GetChild(obj, index);
                if (child is FrameworkElement && (child as FrameworkElement).Name == name)
                {
                    return child;
                }
 
                child = GetObject(child, name);
                if (child != null)
                {
                    return child;
                }
            }
 
            return child;
        }
