RadTreeList supports paging functionality which allows the users to view the data, separated in chunks. This is helpful in cases where the control is bound to a large collection of data which would be impractical or even impossible to display on a single page. Depending on the developers' preferences, the appearance of the pager may vary from a simple page-number buttons to a more sophisticated slider control.

To enable this functionality in RadTreeList, you should set the AllowPaging property to true.

<telerik:RadTreeList RenderMode="Lightweight" ID="RadTreeList1" runat="server" AllowPaging="true" />

RadTreeList exposes the PageSizeControlType property in its PagerStyle property collection which is an enum of type PagerDropDownControlType.It has three values available with RadComboBox being the default one:

  • None

  • RadComboBox

  • RadDropDownList

As it name implies, the property specifies what type of page size drop down control will be rendered.The property provides an easy way to switch off the page size combo or replace it with its light weight counterpart RadDropDownList.
