问题描述
在我的应用程序中，当用户设置光标或键入选择时，网格将出现在选择控件下方以显示数据。然后用户将选择数据。现在，我正在使用combogrid jquery插件。我看过其他论坛的帖子，比如这个问题。但是我没有解决。
我尝试了什么：
在WebService1.asmx中，有一个返回列表数组的方法。
[WebMethod]
[ScriptMethod（ResponseFormat = ResponseFormat.Json）]
public List< student> AutoArrayList（字符串查询）
{
//根据Query参数来做你的逻辑
List< student> lstStudents = new List< student>（）;
lstStudents.Add（新学生{StudentID = 1，StudentName =ABC}）;
lstStudents.Add（new学生{StudentID = 2，StudentName =DEF}）;
lstStudents.Add（新学生{StudentID = 3，StudentName =GHI}）;
lstStudents .Add（新学生{StudentID = 4，StudentName =JKL}）;
返回lstStudents;
}
公共班学生
{
public int StudentID {get;组; } $ / $
public string StudentName {get;组; }
}
默认.aspx中的

}，

}）;
$（'＃drpSelectStudents'）。combogrid（{

textField：'StudentName'，
// url：'/ combogrid / GetStudentsInfo'，
//来源：jsonData，

}）;
//获取datagrid对象
var g = $（'＃drpSelectStudents'）。combogrid（'grid'）;
//将数据分配给datagrid
g.dat agrid（'loadData'，jsonData）;
}）;
< / script>
in html正文
< select id =drpSelectStudentsname =Studentsstyle =width：290px;>< / select>
谁能告诉我错误在哪里以及如何解决这个问题？
感谢所有
In my application, when user set cursor or type on select, grid will be appeared beneath select control to show data. and then user will select data. Now, I am using combogrid jquery plugin. I saw a post from other forum like this issue. but I didn't solve.
What I have tried:
in WebService1.asmx, there is a method that return list array.
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public List<student> AutoArrayList(string Query)
{
//according to the Query parameter to do your logic
List<student> lstStudents = new List<student>();
lstStudents.Add(new Student { StudentID = 1, StudentName = "ABC" });
lstStudents.Add(new Student { StudentID = 2, StudentName = "DEF" });
lstStudents.Add(new Student { StudentID = 3, StudentName = "GHI" });
lstStudents.Add(new Student { StudentID = 4, StudentName = "JKL" });
return lstStudents;
}
public class Student
{
public int StudentID { get; set; }
public string StudentName { get; set; }
}
in Default.aspx,
<link href="Scripts/easyui.css" rel="stylesheet" type="text/css" />
<link href="Scripts/icon.css" rel="stylesheet" type="text/css" />
<script src="Scripts/jquery.easyui.min.js" type="text/javascript"></script>
<script src="Scripts/jquery.min.js" type="text/javascript"></script>
<script src="Scripts/jquery.combogrid.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
var objval = "param";
var jsonData = [];
$.ajax({
type: "POST",
async: false,
contentType: "application/json; charset=utf-8",
url: '<%=ResolveUrl("WebService1.asmx/AutoArrayList") %>',
data: "{'Query':'" + objval + "'}",
dataType: "json",
success: function (data) {
jsonData = data.d;
},
error: function (result) {
alert("Error");
}
});
$('#drpSelectStudents').combogrid({
panelWidth: 290,
value: '006',
idField: 'StudentID',
textField: 'StudentName',
//url: '/combogrid/GetStudentsInfo',
//source:jsonData,
columns: [[
{ field: 'StudentName', title: 'StudentName', width: 60}]]
});
// get the datagrid object
var g = $('#drpSelectStudents').combogrid('grid');
//assign the data to datagrid
g.datagrid('loadData', jsonData);
});
</script>
in body of html
<select id="drpSelectStudents" name="Students" style="width:290px;"></select>
can anyone tell me where the error is and how can I fix this?
Thanks all
