[Solved] Programmatically scrolling row to top

[Roberto]

Hi,

I have a grid view on a pretty long Silverlight web part and I want to programmatically scroll to an specified item but making this the item at the top. Using the ScrollIntoView I can scroll it to the bottom but not to the top. Any way to do this out of the box?

Hi Roberto,

 Indeed generally the ScrollIntoView method will scroll so that the item is visible, it will not show it at the very top of the visible area.

What you may do to scroll a specific item to the top is to first scroll outside of the visible area and then scroll to the specific item using ScrollIntoViewAsync method. For example if you would like to scroll to item[5] of the playersGrid, then your code should look like this one:

GridViewScrollViewer scrollViewer = this.playersGrid.ChildrenOfType<GridViewScrollViewer>().FirstOrDefault();
            scrollViewer.ScrollToVerticalOffset(scrollViewer.VerticalOffset + scrollViewer.ViewportHeight);
            this.playersGrid.ScrollIntoViewAsync(playersGrid.Items[5], playersGrid.Columns[0],
            new Action<FrameworkElement>((f) =>
            {
                GridViewRow row = f as GridViewRow;
                if (row != null)
                    row.Cells.Cast<GridViewCell>().First(c => c.Column == playersGrid.Columns[0]).Focus();
            }));

 
Is this what are you looking for?

All the best,
