我有一个从SQL数据库填充的Kendo网格。当程序首次启动时，kendo扩展工作正常并在扩展中返回不同的kendo网格但如果我执行新的搜索并返回不同的结果，则展开行不起作用。
我的扩展代码 - ＆gt;
function detailInitd(e) {
TextvalueFile = "manno test";
$.ajax({
type: "post",
data: JSON.stringify({
search_string: TextvalueFile,
}),
url: "/Search.aspx/File_Search",
dataType: "json",
contentType: 'application/json',
success: function (object) {
response(object);
},
complete: function (object) {
},
error: function (object) {
}
});
function response(object) {
var grid = this;
$("<div/>").appendTo(e.detailCell).kendoGrid({
dataSource: {
data: object.d,
schema: {
model: {
path: { type: "string" },
st_size: { type: "number" },
},
},
pageSize: 20,
},
reorderable: true,
resizable: true,
navigatable: true,
selectable: "multiple",
scrollable: true,
sortable: true,
filterable: true,
columnMenu: true,
pageable: {
input: true,
numeric: true
},
columns: [
{ field: "path", title: "Path", width: 200 },
{ field: "st_size", title: "Size", width: 60 },
{ field: "st_blks", title: "BLKS", width: 60 },
{ field: "st_acctime", title: "acc Time", width: 70 },
{ field: "st_modtime", title: "mod Time", width: 75 },
]
});
}
};
原始kendo网格的代码 - ＆gt;
function DisplaySearch() {
}
textS.value = value;
valsearch = textS;
$.ajax({
type: "post",
data: JSON.stringify({
search_string: valsearch,
}),
url: "/Search.aspx/display_search",
dataType: "json",
contentType: 'application/json',
success: function (object) {
response(object);
},
complete: function (object) {
},
error: function (object) {
}
});
function response(object) {
$("#searchGrid").kendoGrid({
theme:"Default",
dataSource: {
data: object.d,
schema: {
model: {
archive_header_key: { type: "number" },
group_Name: { type: "string" },
Server: { type: "string" },
archive: { type: "string" },
display_name: { type: "string" },
file_written: { type: "number" },
session_ID: { type: "string" },
create_browse: {type:"number"},
},
},
pageSize: 20,
},
detailInit: detailInit,
dataBound: function () {
this.expandRow(this.tbody.find("tr"));
},
reorderable: true,
navigatable: true,
selectable: "single",
scrollable: true,
sortable: true,
filterable: false,
columnMenu: true,
reordable: true,
resizable: true,
pageable: {
input: true,
numeric: true,
},
columns: [
{ field: "archive_header_key", title: "Key", width: 50 },
{ field: "Server", title: "Server", width: 75 },
{ field: "group_Name", title: "Group", width: 75 },
{ field: "archive", title: "Archive", width: 50 },
{ field: "display_name", title: "Display name", width: 300 },
{ field: "file_written", title: "Files", width: 50 },
{ field: "session_ID", title: "Session", width: 200 },
{field: "create_browse", title:"Browse", Width: 50},
],
change: function(){
var grid = this;
grid.select().each(function(){
var dataItem = grid.dataItem($(this));
testdata = dataItem.archive_header_key;
grid.expandRow(grid.element.closest("tr"));
})
},
dataBound: function () {
this.expandRow();
},
});
}
任何帮助都将不胜感激。

我认为这是重复的实例。当你正在搜索并打电话给response()时，你可能总是kendoGrid，你必须做类似的事情：
从response()声明变量，如：
var $searchGrid = null;
然后更改response()：
function response(object) {
if($searchGrid){
$searchGrid .destroy();
$("#searchGrid").empty();
$("#searchGrid").remove();
}
$("#searchGrid").kendoGrid({
theme:"Default",
dataSource: {
data: object.d,
schema: {
model: {
archive_header_key: { type: "number" },
group_Name: { type: "string" },
Server: { type: "string" },
archive: { type: "string" },
display_name: { type: "string" },
file_written: { type: "number" },
session_ID: { type: "string" },
create_browse: {type:"number"},
},
},
pageSize: 20,
},
detailInit: detailInit,
dataBound: function () {
this.expandRow(this.tbody.find("tr"));
},
reorderable: true,
navigatable: true,
selectable: "single",
scrollable: true,
sortable: true,
filterable: false,
columnMenu: true,
reordable: true,
resizable: true,
pageable: {
input: true,
numeric: true,
},
columns: [
{ field: "archive_header_key", title: "Key", width: 50 },
{ field: "Server", title: "Server", width: 75 },
{ field: "group_Name", title: "Group", width: 75 },
{ field: "archive", title: "Archive", width: 50 },
{ field: "display_name", title: "Display name", width: 300 },
{ field: "file_written", title: "Files", width: 50 },
{ field: "session_ID", title: "Session", width: 200 },
{field: "create_browse", title:"Browse", Width: 50},
],
change: function(){
var grid = this;
grid.select().each(function(){
var dataItem = grid.dataItem($(this));
testdata = dataItem.archive_header_key;
grid.expandRow(grid.element.closest("tr"));
})
},
dataBound: function () {
this.expandRow();
},
}).data("kendoGrid");;
}
希望这个帮助

有一些示例代码可以检查kendoGrid是否已经初始化： https://www.telerik.com/forums/grid-creation-best-practices
它对我有用，并解决了expandRow问题。
function searchButtonClick() {
var gridElement = $("#grid"),
grid = gridElement.data("kendoGrid");
if (!grid) {
gridElement.kendoGrid({
...
});
} else {
grid.dataSource.read();
}
}
