Namespace:  Microsoft.Office.Tools.Excel
Assembly:  Microsoft.Office.Tools.Excel.v9.0 (in Microsoft.Office.Tools.Excel.v9.0.dll)

public TreeView AddTreeView(
	Range range,
	string name


Type: Range

A Range that provides the bounds for the control.

Type: System.String

The name of the control that can be used to index the control in the ControlCollection instance.

Return Value

Type: Microsoft.Office.Tools.Excel.Controls.TreeView
The TreeView control that was added to the ControlCollection instance.


The name or range argument is null, or the name argument has zero length.


A control with the same name is already in the ControlCollection instance.


The range that was specified is not valid. Multi-area ranges cannot be used. The range should be on the same worksheet as the ControlCollection instance.

The AddTreeView method enables you to add TreeView objects to the end of the ControlCollection. To remove a TreeView that was previously added programmatically, use the Remove method.

The control automatically resizes when the range is resized.

The following code example adds a TreeView control to cells A1 through B6, and then adds a parent node and two child nodes to the control.

private void ExcelRangeAddTreeView()

         treeView1 = this.Controls.AddTreeView(
         this.Range["A1", "B6"], "treeView1");

    treeView1.Nodes.Add("Customer Name");
    treeView1.Nodes[0].Nodes.Add("First Name");
    treeView1.Nodes[0].Nodes.Add("Last Name");
