ASP.NET Core TreeList Frozen Columns

The Telerik for ASP.NET Core TreeList component provides the opportunity to lock (freeze) columns to a specific position, which is always visible while the user scrolls horizontally.

For the feature to work properly, you need to make sure that:

• Scrolling is enabled.
• At least one column is initially locked.
• The height of the TreeList is defined.
• Explicit pixel widths are set to all columns.
• The total width of all locked columns is either the same, or less than the width of the TreeList minus three times the width of the scrollbar.
• The TreeList is not initialized in a hidden container.

The current example shows a basic TreeList configuration with locked columns as well as features like sorting, column resizing, and reordering while having its column menu enabled.

This TreeList example is part of unique collection of hundreds of ASP.NET Core demos, with which you can see all Telerik ASP.NET Core components and their features in action. View the source code of the demos from the library or directly adapt, and edit them and their theme appearance in Telerik REPL for ASP.NET Core or ThemeBuilder.
