Description

The Telerik TreeList for ASP.NET Core component provides the opportunity to resize its columns.

In order to make the TreeList columns resizable, enable the Resizible property as follows:

The resizing behavior of the TreeList columns depends on whether scrolling is enabled or disabled.

When scrolling is disabled and a TreeList column is resized, other columns change their widths too, so that the sum of all column widths remains constant.

For all the available options of its usage, visit the Resizing of the TreeList columns article
