  • Demo Configurator
  • Scroll height in pixels:
    Spin UpSpin Down
  • Scroll position is retained after postback:

Very often, when constructing a RadTreeList, there are design limitations regarding the size of the treelist. In such cases you will need to enable the client-side treelist scrolling option in order to fit it in the allowed space. In order to do that you need to set the AllowScroll property to true. By default its value is false. The ScrollHeight property specifies the height value beyond which the scrolling will be turned on. The default value is 300px.

Scrolling is fully supported client side and can be configured with the following options:
- Static headers - this option will set the header so that it does not scroll with the treelist and is always visible at the top. Set UseStaticHeaders property to true in order to enable it (the default value is false).
- Save scroll position - this option indicates whether the RadTreeList control will keep the scroll position during postbacks. Set SaveScrollPosition property to true in order to enable it (the default value is false).

In order to display horizontal scroll for navigation, you need to make sure that the total width of the columns (either auto-generated or declaratively set) exceeds the width of the treelist (as demonstrated in the online demo itself). Moreover, to render merely the horizontal scroll and avoid the appearance of the vertical scroll, make sure that the height of the records in the treelist does not exceed the ClientSettings -> Scrolling -> ScrollHeight scroll setting.
