展开当前节点
e.Node.Expanded = true;
CalcNodeHeight 单独设置子节点行高
private void TreeList_CalcNodeHeight(object sender, CalcNodeHeightEventArgs e) { if (!e.Node.Nodes.Any()) { e.NodeHeight = 30; } }
NodeCellStyle 重绘网格样式
e.Column.FieldName e.Appearance.ForeColor = ColorTranslator.FromHtml("#666666");
CustomColumnDisplayText 重绘网格显示的值
e.DisplayText = "自定义显示文本";
根据坐标 获取选中行
// 获取鼠标点击时选中的节点 或者直接根据X Y 坐标 new Point(x,y) TreeListNode currentNode = this.treeList.GetNodeAt(e.Point); // 设置焦点行 this.treeList.FocusedNode = currentNode; // 通过焦点行取数据 var focused = this.treeList.GetFocusedRow() as Dto;
GetStateImage 自带的行头绑定图片设置图片
private void TreeList_GetStateImage(object sender, GetStateImageEventArgs e) { // 获取所有图片对应的名称 var keys = this.imageCollection.Images.Keys; // 获取当前节点绑定的图片位置是第几个 e.NodeImageIndex = keys.IndexOf(e.Node.GetValue("ImgName").ToString()); }

TreeNodeBaseDto 基类
- 所有是 TreeList 的数据源的实体 建议继承于它
-
public class TreeNodeBaseDto { public Guid Id { get; set; } public Guid? ParentId { get; set; } }封装的使用流程
1. 拖入封装好的控件 2. 设置列的一些需要格式化的信息 这些值都是和 Column 的 FieldName 相对应的 this.treeList.VisibleColumnsList = new List<string>{}; this.treeList.CustomWidthColumns = new Dictionary<string, int>(); this.treeList.FormatColumnsList = new List<string>(); 3. 绑定一些需要的事件 this.treeList.CustomColumnDisplayText += TreeList_CustomColumnDisplayText; this.treeList.NodeCellStyle += TreeList_NodeCellStyle; 4. 设置数据源 this.treeList.SetDataSource(new List<Dto>{});
