Examples
The following code example demonstrates how to use the BorderStyle enumeration and the BorderStyle, ShowLines, Scrollable, HideSelection and ShowRootLines properties. To run this example, paste the following code in a form and call the InitializeTreeView
method in the form's constructor or Load
method.
// Declare the TreeView control.
internal:
System::Windows::Forms::TreeView^ TreeView1;
private:
// Initialize the TreeView to blend with the form, giving it the
// same color as the form and no border.
void InitializeTreeView()
{
// Create a new TreeView control and set the location and size.
this->TreeView1 = gcnew System::Windows::Forms::TreeView;
this->TreeView1->Location = System::Drawing::Point( 72, 48 );
this->TreeView1->Size = System::Drawing::Size( 200, 200 );
// Set the BorderStyle property to none, the BackColor property to
// the form's backcolor, and the Scrollable property to false.
// This allows the TreeView to blend in form.
this->TreeView1->BorderStyle = BorderStyle::None;
this->TreeView1->BackColor = this->BackColor;
this->TreeView1->Scrollable = false;
// Set the HideSelection property to false to keep the
// selection highlighted when the user leaves the control.
// This helps it blend with form.
this->TreeView1->HideSelection = false;
// Set the ShowRootLines and ShowLines properties to false to
// give the TreeView a list-like appearance.
this->TreeView1->ShowRootLines = false;
this->TreeView1->ShowLines = false;
// Add the nodes.

array<TreeNode^>^temp2 = {gcnew TreeNode( "Features",temp0 ),gcnew TreeNode( "System Requirements",temp1 )};
this->TreeView1->Nodes->AddRange( temp2 );
// Set the tab index and add the TreeView to the form.
this->TreeView1->TabIndex = 0;
this->Controls->Add( this->TreeView1 );
}
// Declare the TreeView control.
internal System.Windows.Forms.TreeView TreeView1;
// Initialize the TreeView to blend with the form, giving it the
// same color as the form and no border.
private void InitializeTreeView()
{
// Create a new TreeView control and set the location and size.

Remarks
When the BorderStyle property is set to Fixed3D, the TreeView has a sunken, three-dimensional appearance. To display a flat, thin border around the TreeView control, set the BorderStyle property to FixedSingle.
