XtraTreeList如何定位？

imiracle

我使用了DevExpress的XtraTreeList，现在必须根据其中能标示出某一行的数据作出行定位选择。请问如何实现

DevExpress.XtraTreeList.Nodes.TreeListNode TN;

//遍历搜索
public void GetNode(DevExpress.XtraTreeList.Nodes.TreeListNodes tc, string pSelected)
{

    foreach (DevExpress.XtraTreeList.Nodes.TreeListNode TNode in tc)
    {
        if (TNode.GetValue(this.treeList1.KeyFieldName).ToString() == pSelected)
        {
            TN = TNode;
        }
        if (TNode.GetValue("OrganizeName").ToString() == pSelected)
        {
            TN = TNode;
        }
        GetNode(TNode.Nodes, pSelected);
    }
}   

private void button1_Click(object sender, EventArgs e)
{
    GetNode(this.treeList1.Nodes, this.textBox1.Text);

    if (TN != null)
    {
        //设置焦点
        this.treeList1.SetFocusedNode(TN);
    }
}

private void treeList1_FocusedNodeChanged(object sender, DevExpress.XtraTreeList.FocusedNodeChangedEventArgs e)
{
    DevExpress.XtraTreeList.TreeListMultiSelection mMSTN = this.treeList1.Selection;

    for (int i = 0; i < mMSTN.Count; i++)
    {
        this.textBox1.Text = mMSTN[i][this.treeList1.KeyFieldName].ToString() + ":" + mMSTN[i][this.treeList1.ParentFieldName].ToString();
    }
}
