[英]JSON returned from ASP.NET does not bind with Kendo grid
我可以使用以下代码成功对Web方法进行AJAX调用,并且Web方法返回粘贴在下面的JSON:
我的网络方法
[WebMethod]
public static string GetJson()
{
string query = "SELECT top 10 cast(ClientUID as varchar) ClientUID FROM <tablename>";
SqlCommand cmd = new SqlCommand(query);
// Populate the DataSet.
DataSet data = GetData(cmd);
// return the Customers table as JSON.
DataTable dt = data.Tables[0];
var returnJSON = (from p in dt.AsEnumerable()
select new
{
ClientUID = p.Field<string>("ClientUID")
}).ToList();
var serializer = new JavaScriptSerializer();
string json = serializer.Serialize(returnJSON);
return json;
}
Web方法返回的JSON:
[{“ ClientUID”:“ 1”},{“ ClientUID”:“ 2”},{“ ClientUID”:“ 3”},{“ ClientUID”:“ 4”},{“ ClientUID”:“ 5”} ,{“ ClientUID”:“ 6”},{“ ClientUID”:“ 7”},{“ ClientUID”:“ 8”},{“ ClientUID”:“ 9”},{“ ClientUID”:“ 10”} ]
使用AJAX调用Web方法
<script type="text/javascript">
$(document).ready(function() {
$.ajax(
{
type: "POST",
url: "ServeClientCalls.aspx/GetJson",
data: {},
contentType: "application/json;charset=utf-8",
dataType: "json",
async: true,
cache: false,
success: function(msg) {
//checking the content return from the above web method
$("#msg").html(msg.d);
//Binding to kendo Grid
$("#grid").kendoGrid({
dataSource: {
data: msg.d,
schema: {
model: {
fields: {
ClientUID: { type: "string" }
}
}
},
pageSize: 20
},
height: 430,
filterable: true,
sortable: true,
pageable: true,
columns: [
{ field: "ClientUID" }
]
});
},
error: function(x, e) {
$("#msg").html(x.responseText);
}
});
});
</script>
问题:我的网格未绑定,仅显示标题,而当我以下面提到的方式使用代码时,它正在工作
<script type="text/javascript">
$(document).ready(function() {
$.ajax(
{
type: "POST",
url: "ServeClientCalls.aspx/GetJson",
data: {},
contentType: "application/json;charset=utf-8",
dataType: "json",
async: true,
cache: false,
success: function(msg) {
//checking the content return from the above web method
$("#msg").html(msg.d);
**var p = [{ ClientUID: 1 }, { ClientUID: 2 }, { ClientUID: 3 }, { ClientUID: 4 }, { ClientUID: 5 }, { ClientUID: 6 }
, { ClientUID: 7 }, { ClientUID: 8 }
, { ClientUID: 9 }, { ClientUID: 10}];**
//Binding to kendo Grid
$("#grid").kendoGrid({
dataSource: {
**data: p,**
schema: {
model: {
fields: {
ClientUID: { type: "string" }
}
}
},
pageSize: 20
},
height: 430,
filterable: true,
sortable: true,
pageable: true,
columns: [
{ field: "ClientUID" }
]
});
},
error: function(x, e) {
$("#msg").html(x.responseText);
}
});
});
</script>
在模式部分下使用数据:“ d” 。 那应该工作。
