我不确定如何调试此错误。
我有一个kendo网格，允许用户拖放以对行进行排序，还允许用户更新这些行中的单元格。但是在添加排序功能后，我在尝试更新行时遇到此错误：
jQuery.Deferred exception: Cannot read property 'models' of undefined TypeError: Cannot read property 'models' of undefined
我有这段代码：
@(Html.Kendo().Grid<DocumentProperties>(Model.CurrentList)
.Name("Grid")
.Columns(columns =>
{
columns.Bound(p => p.ID).Visible(false);
columns.Bound(p => p.SortOrder).Visible(false);
columns.Bound(p => p.DisplayText).Title("Title");
columns.Bound(p => p.FileName).Title("File Name");
columns.Bound(p => p.ID).ClientTemplate(@Html.ActionLink("View", "ViewDocument", new { id = "did" }, new { target = "_blank" }).ToHtmlString().Replace("did", "#: ID #")).Title("").Width(80); //creates link to view the uploaded document
columns.Bound(p => p.ID).ClientTemplate(@Html.ActionLink("Remove", "DeleteDocument", new { id = "did" }, new { onclick = "return confirm('Are you sure you want to delete this document?');", style = "color:Red;" }).ToHtmlString().Replace("did", "#: ID #")).Title("").Width(80);
columns.Command(commands =>
{
commands.Edit(); // The "edit" command will edit and update data items.
}).Title("").Width(80);
})
.DataSource(dataSource => dataSource
.Ajax()
.Update(update => update.Action("DocAttributeUpdate", "Blurb")) // Action invoked when the user saves an updated data item.
.Events(events => events.Error("error_handler"))
.PageSize(20)
.ServerOperation(false)
.Model(model =>
{
model.Id(p => p.ID); // Specify the property which is the unique identifier of the model.
model.Field(p => p.ID).Editable(false); // Make the ID property not editable.
model.Field(p => p.SortOrder).Editable(false); // Make the SortOrder property not editable.
model.Field(p => p.FileName).Editable(false); // Make the FileName property not editable.
model.Field(p => p.DisplayText).Editable(true); // Make the DisplayText property editable.
})
)
.Sortable(sortable => sortable
.Enabled(true)
)
.Pageable(pageable => pageable
//.Refresh(true) Need to figure this out. Doesn't refresh properly.
.PageSizes(true)
.ButtonCount(5))
.Resizable(r => r.Columns(true))
.Selectable(selectable => selectable.Mode(GridSelectionMode.Single).Type(GridSelectionType.Row)) //make each row selectable
)
@(Html.Kendo().Sortable() //this adds the cool drag and drop sorting
.For("#Grid")
.Filter("table > tbody > tr")
.Cursor("move")
.HintHandler("noHint")
.PlaceholderHandler("placeholder")
.ContainerSelector("#Grid tbody")
.Events(events => events.Change("onChange"))
)
<script type="text/javascript">
var noHint = $.noop;
function placeholder(element) {
return element.clone().addClass("k-state-hover").css("opacity", 0.65);
}
function onChange(e) {
var grid = $("#Grid").data("kendoGrid"),
skip = grid.dataSource.skip(),
oldIndex = e.oldIndex + skip,
newIndex = e.newIndex + skip,
dataItems = grid.dataSource.data(),
dataItem = grid.dataSource.getByUid(e.item.data("uid")); //grab your item and give it a new index. Then remove the item from the list and place in the new index.
grid.dataSource.remove(dataItem);
grid.dataSource.insert(newIndex, dataItem);
var dataList = [];
for (var i = 0; i < dataItems.length; i++) {
dataList[i] = {
ID: dataItems[i].ID,
ClientId: dataItems[i].ClientId,
SortOrder: i,
DisplayText: dataItems[i].DisplayText,
Type: dataItems[i].Type,
MimeType: dataItems[i].MimeType,
FileName: dataItems[i].FileName
};
}
$.ajax({
url: "/Blurb/SaveSortOrder",
type: "POST",
data: {
data: JSON.stringify(dataList) //send our json string back to the server for sorting
}
})
};
当我删除以下代码时：
@(Html.Kendo().Sortable()
更新按钮再次起作用，但我没有拖放排序了。
