弹出页面显示TreeView,点击节点(NavigateUrl)把选择的值赋给父窗体

第一步:在HTML页面增加:

            I.添加控件:

                <asp:TextBox ID="txtKnowDot" runat="server"  Columns="40" MaxLength="50" ReadOnly="True" ></asp:TextBox>
                 <input type="button" id="btnKnowDot" runat="server" onclick="SelectKnowDot()" value="选取..." />

            II.添加JS代码:

                <script language="javascript" type="text/javascript">

                     var newwindow = '';
                       function SelectKnowDot()
                        {
                           var url = '../tkkmtest/TestKnowDotTree.aspx?kmid=<%=KMID %>&KMName=<%=KMName %>';
                           var sfeatures = "left=400,top=200,height=400,width=300";
                           popitup(url,"_blank",sfeatures);

                        }
                        function popitup(url,target,sfeatures)

                        {
                            if (!newwindow.closed && newwindow.location)
                            {
                                newwindow.location.href = url;
                            }
                            else
                            {
                                newwindow=window.open(url,target,sfeatures);

                                if (!newwindow.opener) newwindow.opener = self;
                            }
                                if (window.focus) {newwindow.focus()}
                                return false;
                           }
                    </script>

第二步:在类里面定义属性:KMID 和KMName :

                    private int _kmid;
                    private string _kmname;

                   /// <summary>
                   /// 科目名称
                   /// </summary>
                    public string KMName
                    {
                            get
                            {
                                return _kmname;
                             }
                            set
                            {
                                _kmname = value;
                        }
                    }
                    /// <summary>
                    /// 科目ID
                    /// </summary>
                    public int KMID
                    {
                        get
                        {
                            return _kmid;
                        }
                        set
                        {
                            _kmid = value;
                        }
                    }

第三步:利用TreeView的NavigateUrl属性重定向父窗体:

                TreeNode node = new TreeNode();

                *****

                ***

               node.NavigateUrl = "javascript:opener.form1.txtKnowDot.value='"+要赋给父窗体txtKnowDot 的值+"';parent.window.close()";

        注:

                                    parent.window.close();:关闭窗体.

                        ******:JS调用的方法.

                        ******:要定义的参数.

                        ******:父窗体的控件.
