喜这里的朋友是我的要求：

Hi friends here is my requirement:

当我双击在那个特定的项目应打开（扩大）在测试组树选项卡中的搜索选项卡中的项目。 在搜索选项卡中的项目是列表和测试组树的项目是一个TreeItem。据我了解，扩大在其他选项卡中树项目的唯一方法是使用它的标签名称（唯一的）。

When I double click an item in the "search" tab that particular item should be opened(expand) in the "Test Group Tree" tab. The item in the search tab is a list and the item in Test Group Tree is a TreeItem. According to my knowledge the only way to expand a tree item in other tab is by using its label name(unique).

在这里，我已经使用了下面提到code来实现我的要求。对于现在的测试组树选项卡中打开正确的，当我双击在该项目中的搜索选项卡，但的SelectedItem不扩大（在如预期，仅在测试组树标签打开，没有什么事情发生）。 请帮我达到我的要求。

Here I have used the below mentioned code to implement my requirement. For now the "Test Group Tree" tab opens correctly when i double click in the item in the "search" tab but the SelectedItem is not expanded(opened in the other tab as expected-only the Test Group Tree tab opens and nothing else happens). Please help me achieve my requirement.

private function TSTree_itemDoubleClick(event:ListEvent):void{
    var selectedItem: TSTreeItem = TSTreeItem(TSTreeTestGroup.getSelectedFolderItem());
    this.TSTreeTestGroup.tabMain.selectedIndex=0; // Here i am trying to open a next tab(it works)

    //var selectedSampleItem: TSTreeItem = PLTreeItem(TSTreeTestGroup.treTree.getChildByName(selectedItem.label));
    TestGroupTree(TestGroupManager(this).TSTreeTestGroup).loadPartialTreeItem(selectedItem);  // Here i actually want to refresh the particular tree item       
    TestGroupTree(TestGroupManager(this).TSTreeTestGroup).treTree.expandItem(selectedItem,true,false); // here i am trying to expand the particular tree item
    //TestGroupManager(TestGroupTree(TSTree(event.currentTarget).parentDocument).parentDocument).TSTreeTestGroup.treTree.expandItem(selectedItem, true, false);
    //TestGroupManager(TestGroupTree(TSTree(event.currentTarget).parentDocument).parentDocument).TSTreeTestGroup.loadPartialTreeItem(this.TSTreeTestGroup.treTree.getChildByName(selectedItem.label);
    // in the following i am tryin to get the TreeItemName and expand it accordingly
    TestGroupTree(TestGroupManager(this).TSTreeTestGroup).treTree.expandItem(this.TSTreeTestGroup.treTree.getChildByName(selectedItem.label), true, true);
}

谢谢Advance.Please让我知道如果您有任何疑问。

Thanks in Advance.Please let me know if you have any queries.

推荐答案

请尝试在树中选择的项目，如果找到了扩大​​node.I觉得问题可能是所选择的项目，您将可以通过什么树不断扩大。

try searching the selected item in Tree if the found the expand the node.I think the problem may be the selected item what your are passing to tree for expanding.
