【问题描述】：

我想一次获取在 Devexpress MVC GridView 上选择的行。不是在每个点击的项目上。

【参考方案1】：

参考：How to get all GridView selected keys and pass them to a Controller

您可以在客户端收集所有选定的值（例如，键） 通过ASPxClientGridView.GetSelectedFieldValues 方法和 将它们传递给：

通过 e.customArgs 字典 (Passing Values to Controller Action Through Callbacks) 的 GridView 回调操作； 任何控制器都通过隐藏的输入元素发布操作。

示例代码sn-p：

<script type="text/javascript">
    var selectedIDs;
    function OnBeginCallback(s, e) 
        //Pass all selected keys to GridView callback action
        e.customArgs["selectedIDs"] = selectedIDs;
    
    function OnSelectionChanged(s, e) 
        s.GetSelectedFieldValues("PersonID", GetSelectedFieldValuesCallback);
    
    function GetSelectedFieldValuesCallback(values) 
        //Capture all selected keys
        selectedIDs = "";
        for (var index = 0; index < values.length; index++) 
            selectedIDs += values[index] + ",";
        
        if (selectedIDs.length > 0)
            selectedIDs = selectedIDs.substring(0, selectedIDs.length - 1);
    
    function OnClick(s, e) 
        //Show all selected keys on client side
        alert(selectedIDs);
    
    function OnSubmitClick(s, e) 
        //Write all selected keys to hidden input. Pass them on post action.
        $("#selectedIDsHF").val(selectedIDs);
    
</script>

控制器

namespace Sample.Controllers 
    public class HomeController : Controller 
        PersonsList list = new PersonsList();

        [HttpGet]
        public ActionResult Index() 
            return View(list.GetPersons());
        

        [HttpPost]
        public ActionResult Index(string selectedIDsHF) 
            //Get all selected keys from hidden input
            string _selectedIDs = selectedIDsHF;

            return View(list.GetPersons());
        

        public ActionResult GridViewEditingPartial() 
            //Get all selected keys from e.customArgs on GridView callback
            string _selectedIDs = Request.Params["selectedIDs"];
            ViewData["_selectedIDs"] = _selectedIDs;

            return PartialView(list.GetPersons());
        

    

注意：客户端GetSelectedKeysOnPage Method返回当前页面中显示的选定行的键值。
