我有 Trirand MVC jqGrid 包,但我确信这个问题对整个 jqGrid 都很重要。我有一个绑定到 Id 的列:
new JQGridColumn
{
DataField = "PaymentSchemeId",
HeaderText = "Payment Scheme",
DataType = typeof(ParkadePaymentScheme),
Searchable = true,
SearchToolBarOperation = SearchOperation.IsEqualTo,
SearchType = SearchType.DropDown,
SearchControlID = WidgetNames.DropDownSearchPaymentScheme,
Editable = true,
EditType = EditType.DropDown,
EditorControlID = WidgetNames.DropDownEditPaymentScheme
},
在我的 GridModel (网格的视图模型)中。在显示模式下,网格PaymentSchemeId
按预期显示 的值。在编辑模式下,它显示了一个包含所有支付方案的下拉列表,选择一个后,显示的是一个人的名字而不是 Id,但我认为这只是副作用。
如何设置列以PaymentSchemeId
在显示PaymentSchemeName
属性值时绑定和存储值?
网格渲染的脚本相当长,但我将其全部包括在内,以免删节有意义的内容。

请求的响应/Parkade/IndexDataRequest?jqGridID=IndexGrid
是:
{"page":1,"total":1,"records":1,"rows":[{"id":"1","cell":["","1","Brooklyn Mall","2","True",""]}],"userdata":{}}
我期望它的值为 2 PaymentSchemeId
,因为我的实体对 table 有一个 FK PaymentScheme
,并且我将这些记录之一的 PK 存储在 中PaymentSchemeId
,因此Id
后缀和整个需要下拉列表。如您在 JS 中所见,下拉列表填充在服务器端:
示例,以及添加的其他相关代码。我希望作为一个 IDPaymentSchemeId
有一个int
价值。我得到了我所期望的。下拉列表的值与列定义一起呈现为
"editoptions": {
"value": "3:Pay on Entry;1:Pay on Exit;2:Pay on Foot"
我非常接近逐字复制他们的示例,所以请不要解释为什么 GET 请求有一个jqGridID=IndexGrid
在控制器上被忽略的查询字符串:
public JsonResult IndexDataRequest()
{
var gridModel = new ParkadeGridModel();
JQGridState gridState = gridModel.Grid.GetState();
Session[SessionKeys.JqGridState] = gridState;
SetupGrid(gridModel.Grid);
ViewData["PaymentSchemeId_Data"] = _indexModel.PaymentSchemes;
return gridModel.Grid.DataBind(_indexModel.Items.AsQueryable());
}
在你问之前:
private void SetupGrid(JQGrid grid, string indexMsg = null)
{
_indexModel = BuildIndexModel();
grid.DataUrl = Url.Action("IndexDataRequest");
grid.EditUrl = Url.Action("EditRow");
grid.Columns.Insert(0, new JQGridColumn
{
EditActionIconsColumn = true,
EditActionIconsSettings = new EditActionIconsSettings
{
SaveOnEnterKeyPress = true
},
HeaderText = "Edit Actions",
Width = 50,
Searchable = false,
Sortable = false
});
SetupParkadeNameDropDown(grid);
SetupPaymentSchemeDropDown(grid);
SetupYesNoDropDown(grid);
}
和:
private void SetupPaymentSchemeDropDown(JQGrid parkadesGrid)
{
JQGridColumn paymentColumn = parkadesGrid.Columns.Find(c => c.DataField == "PaymentSchemeId");
if (parkadesGrid.AjaxCallBackMode == AjaxCallBackMode.RequestData)
{
var searchList = _indexModel.Items.Select(m => m.PaymentSchemeName).Distinct().Select(l => new SelectListItem { Text = l, Value = l });
paymentColumn.SearchList = searchList.ToList();
paymentColumn.SearchList.Insert(0, new SelectListItem { Text = "All", Value = "" });
var editList = _paymentSchemeRepository.Get().OrderBy(p => p.Name).ToList();
paymentColumn.EditList = editList.Select(l => new SelectListItem { Text = l.Name, Value = l.Id.ToString() }).ToList();
}
}
我认为我应该使用“选择器”作为该 FK 列的格式化程序,但我仍在试图弄清楚如何CustomFormatter
在我的列定义中使用 Trirand 来实现这一点,因为他们没有费心给我们一个 DropDownFormatter 选项。
