Public Property ImageList As ImageList
An ImageList that specifies the images to display on the tabs.
The following code example creates a TabControl with one TabPage. This example uses the ImageList property to display images, from the collection defined by the ImageList named myImages
, on the tabs of tabControl1
.
using namespace System::Drawing;

public ref class Form1: public Form

Form1()
{
IContainer^ components = gcnew System::ComponentModel::Container;
ResourceManager^ resources = gcnew ResourceManager( Form1::typeid );
TabControl^ tabControl1 = gcnew TabControl;
TabPage^ tabPage1 = gcnew TabPage;
// Declares and instantiates the ImageList Object*.
ImageList^ myImages = gcnew ImageList( components );
tabControl1->Controls->Add( tabPage1 );
// Sets the images in myImages to display on the tabs of tabControl1.
tabControl1->ImageList = myImages;
tabPage1->ImageIndex = 0;
tabPage1->Text = "tabPage1";
// Gets the handle that provides the data of myImages.
myImages->ImageStream = (dynamic_cast<ImageListStreamer^>(resources->GetObject( "myImages.ImageStream" )));
// Sets properties of myImages.
myImages->ColorDepth = ColorDepth::Depth8Bit;
myImages->ImageSize = System::Drawing::Size( 16, 16 );
myImages->TransparentColor = Color::Transparent;
this->Controls->Add( tabControl1 );
}
};

{
Application::Run( gcnew Form1 );

To display an image on a tab, set the ImageIndex property of that TabPage. The ImageIndex acts as the index into the ImageList.
