The TreeList allows you to save and restore its layout settings that a user can change in the UI. A TreeListPersistentLayout object stores layout settings on the TreeList level. The TreeListPersistentLayout.Columns collection stores layout settings for columns. Each item (a TreeListPersistentLayoutColumn object) includes the following data:
| Saved Information | TreeList Column Parameter | TreeListPersistentLayoutColumn Property |
|---|---|---|
| Column type | A column type defined in the markup: data, band, command, or selection. | LayoutColumn.ColumnType |
| Data field name | DxTreeListColumn.FieldName | LayoutColumn.FieldName |
| Sort index | DxTreeListColumn.SortIndex | LayoutColumn.SortIndex |
| Sort direction | DxTreeListColumn.SortOrder | LayoutColumn.SortOrder |
| Position | DxTreeListColumn.VisibleIndex | LayoutColumn.VisibleIndex |
| Visibility | DxTreeListColumn.Visible | LayoutColumn.Visible |
| Width | DxTreeListColumn.Width | LayoutColumn.Width |
Handle the following events to save and restore the TreeList layout automatically:
- LayoutAutoSaving
- Fires when the TreeList layout changes.
- LayoutAutoLoading
- Fires when the DxTreeList component finishes initialization and starts to load its layout.
To save and restore the TreeList layout on demand (for example, on a button click), call the following methods:
- SaveLayout()
- Saves information about the TreeList layout.
- LoadLayout(TreeListPersistentLayout)
- Restores the TreeList layout.
