Devexpress 设置TreeList图标

几年不用Devexpress,居然TreeList设置图标都忘记怎么弄了，记录下

1、窗口上拖动一个TreeList和一个ImageCollection

 

 

 

2、设置ImageCollection图像

 

 

 3、设置

 

 4、代码如下

public Form1()
{
    InitializeComponent();
    //TreeListNode treeNode = new TreeListNode();
    //treeNode.ImageIndex = 0;
    //treeNode.SetValue("ID", "111");
    //treeList1.Nodes.Add(treeNode);

    List<DataSingle> dataSingles = new List<DataSingle>();
    DataSingle dataSingle = new DataSingle();
    dataSingle.ID = 1111;
    dataSingle.TEXT = "22222";
    dataSingle.ImgIndex = 0;
    dataSingles.Add(dataSingle);
    treeList1.DataSource = dataSingles;

}
public class DataSingle
{
    public int ID { get; set; }
    public string TEXT { get; set; }
    public int ImgIndex { get; set; }
}

private void treeList1_CustomDrawNodeImages(object sender, DevExpress.XtraTreeList.CustomDrawNodeImagesEventArgs e)
{
    if(e.Node.GetValue("ImgIndex")!=null)
    e.SelectImageIndex = int.Parse(e.Node.GetValue("ImgIndex").ToString());
}

　　

5、结果
