TreeList Templates

You can customize the TreeList appearance and behavior through the various templates it provides so you can add more details for your users - such as format numbers and dates, show images and so on.

The TreeList component can use templates for:

  • columns (cells) - the rendering of each cell (column). You can, for example, change string formats or add your own components.

  • editing of a cell - when a cell is in edit mode, it will render this template where you can use custom editors, components and logic.

  • rows - the entire rendering of the tr element of the row, so you can fully customize the treelist behavior and rendering.

  • column header - the title portion of the column.

  • filter - the content of the filter cell or filter menu where you can implement custom rendering and logic for the filters.

Like other Blazor content, most of them can receive a context argument that is the type of the model. To use templates, you must bind the treelist to a named model. The filter and header templates are the exception as they are not related to rows and models.

You must make sure to provide valid HTML in the templates.
