    • Syncfusion.Shared.Base
  3. Include the required namespace.

    using Syncfusion.Windows.Forms.Tools;
    Imports Syncfusion.Windows.Forms.Tools
  4. Create an instance of the GroupView control, and then add it to the form.

    GroupView groupView1 = new GroupView();
    Dim groupView1 As GroupView = New GroupView()
  5. Add items to GroupView container using the GroupViewItems collection property.

    this.groupView1.GroupViewItems.AddRange(new GroupViewItem[] {
                new GroupViewItem("GroupViewItem0",0,true, null, "GroupViewItem0"),
                new GroupViewItem("GroupViewItem1",1,true, null, "GroupViewItem0"),
                new GroupViewItem("GroupViewItem2",2,true, null, "GroupViewItem0")});
    this.groupView1.FlatLook = true;
    Me.groupView1.GroupViewItems.AddRange(New GroupViewItem() { 
                New GroupViewItem("GroupViewItem0",0,True, Nothing, "GroupViewItem0"), 
                New GroupViewItem("GroupViewItem1",1,True, Nothing, "GroupViewItem0"), 
                New GroupViewItem("GroupViewItem2",2,True, Nothing, "GroupViewItem0"True, Nothing, "GroupViewItem0")})
    Me.groupView1.FlatLook = True

Adding images

To add images to the GroupView, ImageList control must be added to the form with images.

ImageList imageList1 = new ImageList();
imageList1.ImageStream = ((System.Windows.Forms.ImageListStreamer)(resources.GetObject("imageList1.ImageStream")));
this.imageList1.Images.SetKeyName(0, "holo.png");
this.imageList1.Images.SetKeyName(1, "edge.png");
this.imageList1.Images.SetKeyName(2, "light.png");
Dim imageList1 As New ImageList()
imageList1.ImageStream = (CType(resources.GetObject("imageList1.ImageStream"), System.Windows.Forms.ImageListStreamer))
Me.imageList1.Images.SetKeyName(0, "holo.png")
Me.imageList1.Images.SetKeyName(1, "edge.png")
Me.imageList1.Images.SetKeyName(2, "light.png")

After adding images, assign ImageList to the SmallImageList property, and then set the SmallImageView property to true for the GroupView control.

groupView1.SmallImageList = this.imageList1;
groupView1.SmallImageView = true;
groupView1.SmallImageList = Me.imageList1
groupView1.SmallImageView = True
