Scroll to horizontal offset in datagrid

[Gary Pansino]

How do you do the equivalent of ScrollViewer.ScrollToHorizontalOffset(##) for a data grid?

I have successfully used the .ScrollColumnIntoView(col#) command, but when combined with a frozen first column in snapped view, the datagrid scrolls to the column and cuts off the leftmost portion of the target column, so I need more precision.

Thank you.

Hi Gary,

 

We have analysed your query, you can achieve your requirements by getting the ScrollableContentViewer from VisualTreeHelper, and then you can directly use the ScrollToHorizontalOffset method from ScrollableContentViewer object.

Please refer the following code snippet.

Code Snippet [C#]:

void MainPage_Loaded(object sender, RoutedEventArgs e)

{

    scrollViewer = FindDescendant(datagrid, typeof(ScrollableContentViewer)) as ScrollableContentViewer;

    scrollViewer.ScrollToHorizontalOffset(offset);

}

 

DependencyObject FindDescendant(DependencyObject startingFrom, Type typeDescendant)

{

    DependencyObject visual = null;

    var iCount = VisualTreeHelper.GetChildrenCount(startingFrom);

    for (var i = 0; i < iCount; ++i)

    {

        var child = VisualTreeHelper.GetChild(startingFrom, i);

        if (typeDescendant == child.GetType())

        {

            visual = child;

            break;

        }

        visual = FindDescendant(child, typeDescendant);

        if (visual != null)

            break;

    }

    return visual;

}
