Popup Editing

TreeList can display a popup edit form. The form can include any fields from the bound data source, regardless of whether the corresponding column is visible in the grid (see the Head column).

To enable this behavior in your application, do the following:

TreeList uses the DevExtreme Form and Popup components to display the popup form. Their default configurations are defined automatically. If these configurations do not meet your requirements, you can redefine them in the editing object's form and popup properties. For more information about this edit mode's limitations, refer to the descriptions of these properties.
