Expand/Collapse 在 Telerik RadGrid 中不工作

Question

我正在使用带有 NestedViewTemplate 的 Telerik RadGrid 在我的 MVC 应用程序中显示数据。以下是我的代码

                        </telerik:RadGrid>

有什么建议吗？

我该怎么做Expand/Collapse？还有什么方法可以使嵌套网格可以滚动吗？

我无法从服务器端执行 expand/collapse 所以我使用 javascript 执行了以下是解决方案

   var imageButtonPath = null;

    function RowClicked(sender, eventArgs) {
        var grid = sender;

        var rowIndex = eventArgs.get_itemIndexHierarchical();

        if (rowIndex.indexOf(':') != -1) {
            rowIndex = rowIndex.substr(rowIndex.lastIndexOf('_') + 1);
        }

        var tableView = eventArgs.get_tableView();

        var row = tableView.get_dataItems()[rowIndex];

        if (tableView.getCellByColumnUniqueName(row, "ExpandColumn")) {

            if (row.get_expanded() == false) {
                row.set_expanded(true);
                imageButton = tableView.getCellByColumnUniqueName(row, "ExpandColumn").childNodes[0];
                imageButton.className = "rgCollapse";
            }
            else {
                row.set_expanded(false);
                imageButton = tableView.getCellByColumnUniqueName(row, "ExpandColumn").childNodes[0];
                imageButton.className = "rgExpand";
            }
        }
        GridCreated(sender, eventArgs)
    }

我在行点击事件中调用了这个 javascript 函数。
