Remarks

The UnselectCells method discards the selection of multiple cells in the specified range. The start and end points of the range are specified using the cells located at the intersection of the nodes (rows) and columns passed as parameters. To select cells, use the TreeList.SelectCell or TreeList.SelectCells method.

The code snippet below shows how to unselect a particular range of cells in the TreeList using the UnselectCells method.

C#
VB.NET

csharp

treeList1.UnselectCells(treeList1.Nodes[0].Nodes[0], treeList1.Columns[1], treeList1.Nodes[0].Nodes[1], treeList1.Columns[2]);

treeList1.UnselectCells(treeList1.Nodes[0].Nodes[0], treeList1.Columns[1], treeList1.Nodes[0].Nodes[1], treeList1.Columns[2])

After the selection is changed, the TreeList.SelectionChanged event is raised.

Note

The UnselectCells method is not in effect if multiple cell selection is disabled. This mode can be enabled by setting the TreeListOptionsSelection.MultiSelect property to true and the TreeListOptionsSelection.MultiSelectMode property to CellSelect.
