控件使用

1. 设置Nodes。可以在设计器中选中控件，点击【Nodes属性】设置，如图:

也可以通过代码添加：

    C#：
                Swebui.Controls.TreeSelectNode treeViewNode1 = new Swebui.Controls.TreeSelectNode() { TreeID = "1", Text = "水果" };
                Swebui.Controls.TreeSelectNode treeViewNode2 = new Swebui.Controls.TreeSelectNode() { TreeID = "2", Text = "蔬菜" };
                Swebui.Controls.TreeSelectNode treeViewNode3 = new Swebui.Controls.TreeSelectNode() { TreeID = "11", Text = "苹果" };
                Swebui.Controls.TreeSelectNode treeViewNode5 = new Swebui.Controls.TreeSelectNode() { TreeID = "12", Text = "李子" };
                Swebui.Controls.TreeSelectNode treeViewNode6 = new Swebui.Controls.TreeSelectNode() { TreeID = "13", Text = "香瓜" };
                Swebui.Controls.TreeSelectNode treeViewNode7 = new Swebui.Controls.TreeSelectNode() { TreeID = "14", Text = "菠萝" };
                Swebui.Controls.TreeSelectNode treeViewNode4 = new Swebui.Controls.TreeSelectNode() { TreeID = "21", Text = "黄瓜" };
                Swebui.Controls.TreeSelectNode treeViewNode8 = new Swebui.Controls.TreeSelectNode() { TreeID = "3", Text = "鱼" };
                treeViewNode1.Nodes.AddRange(new TreeSelectNode[] { treeViewNode3, treeViewNode4, treeViewNode5, treeViewNode6 });
                treeViewNode2.Nodes.Add(treeViewNode7);
                treeSelect1.Nodes.AddRange(new TreeSelectNode[] { treeViewNode1, treeViewNode2, treeViewNode8 });
        
                            

2. 设置默认选中项

    C#：
                ///需要将选中项的TreeID组成数组赋值给DefaultValue属性
                treeSelect1.DefaultValue = new string[] { "1" };
        
                                        

3. 选中事件。在设计器中点击事件-Press 添加

    C#：
                private void treeSelect1_Press(object sender, TreeSelectPressEventArgs args)
                {
                    //若是多选 请遍历 args.Selections 来获取所有选中项id
                    Toast("press-" + args.TreeID);
                }
