Remarks

If Model data is invalid or an error occurs during data changes, you can use the treelist’s SetEditErrorText method to display a common error text in an error node at the bottom of the edit form.

This method can be used together with the automatic Model error visualization feature controlled by the treelist’s MVCxTreeListSettingsEditing.ShowModelErrorsForEditors property.
