public:
[System::Runtime::CompilerServices::Extension]
 static Microsoft::Office::Tools::Excel::Controls::TreeView ^ AddTreeView(Microsoft::Office::Tools::Excel::ControlCollection ^ controls, Microsoft::Office::Interop::Excel::Range ^ range, System::String ^ name);

static member AddTreeView : Microsoft.Office.Tools.Excel.ControlCollection * Microsoft.Office.Interop.Excel.Range * string -> Microsoft.Office.Tools.Excel.Controls.TreeView

<Extension()>
Public Function AddTreeView (controls As ControlCollection, range As Range, name As String) As TreeView

Parameters

controls

ControlCollection

The collection to add the control to. Do not supply this parameter yourself. When you call this method on the collection returned by the Controls property (in an application-level project) or the Controls property (in a document-level project), this parameter is supplied automatically.

range

Range

A Range that provides the bounds for the control.

name

String

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

Returns

TreeView

The TreeView control that was added to the ControlCollection instance.

Exceptions

ArgumentNullException

The name or range argument is null, 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.

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. To use this example, run it from the Sheet1 class in a document-level project.

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");
}

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 

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.
