Exceptions

Exception Condition
ArgumentNullException

The name or range argument is nulla null reference (Nothing in Visual Basic), or the name argument has zero length.
ControlNameAlreadyExistsException

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

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.

Remarks

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.

Examples

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 Sub ExcelRangeAddTreeView()

    Dim TreeView1 As Microsoft.Office.Tools.Excel. _
        Controls.TreeView = Me.Controls.AddTreeView( _
        Me.Range("A1", "B6"), "TreeView1")

    TreeView1.Nodes.Add("Customer Name")
    TreeView1.Nodes(0).Nodes.Add("First Name")
    TreeView1.Nodes(0).Nodes.Add("Last Name")

End Sub

private void ExcelRangeAddTreeView()
{

    Microsoft.Office.Tools.Excel.Controls.TreeView
         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");
}
