没有可显示的记录。请选择其他视图。

调试js代码,查看它的哪个部分得到处理,以及是否出现错误。这有助于您追踪问题所在。

请看下面一行:

alert("Click on row instance: " + eventArgs.get_itemIndexHierarchical());
您尚未定义eventArgs。这是函数的第一行,因此当您单击该行时“什么也不发生”是有意义的

将您的功能更改为如下所示:

function RowClick(rowIndex, eventArgs) {
           alert("Click on row instance: " + eventArgs.get_itemIndexHierarchical());
           var e = window.event;
           var sourceElement;
           alert(sourceElement);
           if (e.srcElement) {
               sourceElement = e.srcElement;
               alert("sourceElement");
           }
           else if (e.target) {
           sourceElement = e.target;
           alert("target");
           }

       alert("About to check ROw Index");
       if (rowIndex != null) {

           alert("Checked ROw Index");
           inputField = grid.MasterTableView.Rows[rowIndex].Control.getElementsByTagName("INPUT")[0];
           alert(inputField);
           selvalue = sourceElement.value;
           alert(selvalue);
           if (inputField != null) {
               alert("About to show it");
               var popuppage = "userroleselect.aspx" + "?sel=" + selvalue + "&avail=" + inputField.value;
               alert("Shown it!");
               window.radopen(popuppage, "UserRoleDialog");
           }
           else {
               alert("Did Not Make it");
           }
       }
   }

请注意eventArgs参数还请注意变量e现在已在函数中定义

如何附加RowClick事件?通过在代码中添加警报进行调试并没有产生太多的效果,因为它似乎偶尔运行,并且没有达到预期效果。很抱歉,这是我的错误。尽管没有显示任何警报锅炉,但问题似乎出在行inputField=grid.MasterTableView.Rows[rowIndex].Control.getElementsByTagName(“输入”)[0];第一个问题是您的警报框应该出现。我会开始注释掉不必要的代码,直到出现警告框。一旦它们出现,我会一次添加一行代码,然后在添加每行代码后进行测试,直到确定问题的确切位置。我清除了所有代码,仍然无法获得popupI。我使用来自的示例代码进行了快速测试,效果非常好。我需要查看您的“简单”行单击函数,以查看发生了什么。连接GridView的onrowclick事件很简单,您应该能够毫无问题地获得警报。@Allison,以上就是我现在所拥有的
