The following properties accept/return TreeListEnterKeyDirection values:

• DxTreeList.EnterKeyDirection
• ITreeList.EnterKeyDirection

Remarks

The EnterKeyDirection property specifies where focus moves after a user presses Enter or Shift+Enter to close the in-place editor.

If the editor is on the last row and GridEnterKeyDirection is Column, Enter will keep the focus on the current cell.

<DxTreeList @ref="TreeList"
            Data="DataSource"
            KeyFieldName="Id"
            ParentKeyFieldName="ParentId"
            HasChildrenFieldName="HasChildren"
            EditMode="TreeListEditMode.EditCell"
            EnterKeyDirection="TreeListEnterKeyDirection.Column">
    <Columns>
        *@* ... *@
    </Columns>
</DxTreeList>

Run Demo: Edit Cell

Note

When EnterKeyDirection is TreeListEnterKeyDirection.Column, focus advances to the next visible cell.
Collapsed rows are not expanded. Focus moves to the next visible row.

User Input Validation

In EditCell mode, the TreeList component validates cell values once the edited row loses focus. Validation behavior on Enter / Shift+Enter depends on the EnterKeyDirection value:

• Column: Validation occurs immediately when you press the key.
• Row: Validation occurs after you edit the last cell in the row and press the key. The component prevents users from editing another row until they address all validation errors.
