JQuery Datatable Plugin Loading Asp.Net Repeater with Ajax Call(使用 Ajax 调用加载 Asp.Net 中继器的 JQuery 数据表插件)
本文介绍了使用 Ajax 调用加载 Asp.Net 中继器的 JQuery 数据表插件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试使用 DataTables 插件为 Ajax 数据绑定 Asp.Net 中继器控件，但它不起作用以下是我的代码.
I am trying to bind Asp.Net Repeater Control for Ajax Data using DataTables Plugin but its not working Following is my Code.
$(document).ready(function () {
$('#tblMessages').dataTable({
"sDom": 'T<"clear">lfrtip',
"oLanguage": { "sSearch": "Search the Messages:" },
"aLengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]],
"iDisplayLength": 25,
"bProcessing": true,
"bServerSide": true,
"bFilter": true,
"sAjaxSource": "../QCDataServices.asmx/GetPatients",
"fnServerData": function(sSource, aoData, fnCallback) {
aoData.push("{pageSize:'20',pageNumber:'1'}");
$.ajax({
"type": "POST",
"dataType": 'json',
"contentType": "application/json; charset=utf-8",
"url": sSource,
"data": aoData,
"success": function (msg) {
fnCallback(msg.d);
}
});
},
"sPaginationType": "full_numbers",
"oTableTools": {
"aButtons": [
"copy",
"csv",
"xls",
{
"sExtends": "pdf"
},
"print"
]
},
"aaSorting": [[0, "desc"]]
});
});
这是作为Json对象获得的类
Here is the Class which is obtained as Json object
public class PatientGridDataSet
{
public int sEcho { get; set; }
public int iTotalRecords { get; set; }
public int iTotalDisplayRecord { get; set; }
public List<Patient> aaData { get; set; }
}
这是服务方法
[WebMethod(EnableSession=true)]
public PatientGridDataSet GetPatients(int pageSize, int pageNumber)
{
var patlist=Patients("", "", "");
return new PatientGridDataSet {sEcho = pageNumber,iTotalRecords = patlist.Count, iTotalDisplayRecord = pageSize, aaData= patlist.Skip(pageSize * pageNumber).Take(pageSize).ToList() };
}
[WebMethod(EnableSession = true)]
public List<Patient> Patients(string searchIn, string Operator, string searchString)
{
List<Patient> result;
try
{
DataRow[] rows;
var table = new dsVw_Patients.vw_PatientsDataTable();
var adapter = new vw_PatientsTableAdapter();
adapter.Fill(table);
//DataTable distinctTable = originalTable.DefaultView.ToTable( /*distinct*/ true);
string hid = Context.Session["HospitalId"] == null ? "0" : Context.Session["HospitalId"].ToString();
string rid = Context.Session["RoleId"] == null ? "0" : Context.Session["RoleId"].ToString();
string uid = Context.Session["UserId"] == null ? "0" : Context.Session["UserId"].ToString();
if (searchIn.Equals(""))
{
rows = hid.Equals("0") ? table.DefaultView.ToTable(true).Select("1=1", "PatientName ASC") : table.DefaultView.ToTable(true).Select("HospitalId="+hid, "PatientName ASC");
if(rid.Equals("5"))
rows = table.DefaultView.ToTable(true).Select("UserId="+uid, "PatientName ASC");
}
else
{
if (hid.Equals("0"))
{
rows = Operator.Contains("%") ? table.DefaultView.ToTable(true).Select(searchIn + " like '" + Operator.Replace("_", searchString) + "'", searchIn + " ASC") : table.DefaultView.ToTable(true).Select(searchIn + " " + Operator + " '" + searchString + "'", searchIn + " ASC");
}
else
{
rows = Operator.Contains("%") ? table.DefaultView.ToTable(true).Select("HospitalId=" + hid+" and "+searchIn + " like '" + Operator.Replace("_", searchString) + "'", searchIn + " ASC") : table.DefaultView.ToTable(true).Select("HospitalId=" + hid + " and " + searchIn + " " + Operator + " '" + searchString + "'", searchIn + " ASC");
}
if (rid.Equals("5"))
{
rows = Operator.Contains("%") ? table.DefaultView.ToTable(true).Select(searchIn + " like '" + Operator.Replace("_", searchString) + "'", searchIn + " ASC") : table.DefaultView.ToTable(true).Select(searchIn + " " + Operator + " '" + searchString + "'", searchIn + " ASC");
}
}
var tieup=new clsTieUpCompanies();
result = rows.Select(row => new Patient
{
PatientId = Convert.ToInt32(row["PatientId"]), PatientName = row["PatientName"].ToString(), Address = row["Address"].ToString(), Street = row["Street"].ToString(), City = row["City"].ToString(), ContactNo = row["Contactno"].ToString(), MobileNo = row["MobileNo"].ToString(), Email = row["Email"].ToString(), State = row["State"].ToString(), Country = row["Country"].ToString(), BPLCardNo = row["BPLCardNo"].ToString(), Company = tieup.GetTieupCompanyName(Convert.ToInt32(row["CompanyId"]))
}).ToList();
}
catch (Exception)
{
result = null;
}
return result;
}
首先，当我调用我的 web 服务方法时，它不会去那里，请告诉我其余代码是否正常这是标记
First Of when i call my webservice method it does not go there please tell me rest code is ok or not Here is the markup
<asp:Repeater ID="rptList" runat="server">
<HeaderTemplate>
<table id="tblMessages">
<thead>
<tr>
<th>
Patient Name
</th>
<th>
Address
</th>
<th>
City
</th>
<th>
Contact No
</th>
<th>
MobileNo
</th>
<th>
BPL Card No.
</th>
</tr>
</thead>
<tbody>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<%# Eval("PatientName")%>
</td>
<td>
<%#Eval("Address")%>
</td>
<td>
<%# Eval("City")%>
</td>
<td>
<%# Eval("ContactNo")%>
</td>
<td>
<%# Eval("MobileNo")%>
</td>
<td>
<%# Eval("BPLCardNo")%>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</tbody> </table>
</FooterTemplate>
</asp:Repeater>

我已经成功了.但是我尝试使用它的真正原因是无视的.仅获取 80 条记录需要花费大量时间.在这里找到我的客户端代码.
I have got it worked.But the very reason i tried used it for is defied. It takes a lot of time to fetch only 80 records. Here Find my client code.
$(document).ready(function () {
var grid = $('#tblMessages').dataTable({
"sDom": 'T<"clear">lfrtip',
"oLanguage": { "sSearch": "Search the Messages:" },

我的网络服务方法是
[WebMethod(EnableSession = true)]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string GetPatients(string jsonAOData)
{
var patients= Patients("", "", "");
var dataTablePager = new DataTablePager<Patient>(jsonAOData, patients);
var formattedList = dataTablePager.Filter();
return JsonConvert.SerializeObject(formattedList);
}
[WebMethod(EnableSession = true)]
public IQueryable<Patient> Patients(string searchIn, string Operator, string searchString)
{
IQueryable<Patient> result ;
try
{
DataRow[] rows;
var table = new dsVw_Patients.vw_PatientsDataTable();
var adapter = new vw_PatientsTableAdapter();
adapter.Fill(table);
//DataTable distinctTable = originalTable.DefaultView.ToTable( /*distinct*/ true);
var hid = Context.Session["HospitalId"] == null ? "0" : Context.Session["HospitalId"].ToString();
var rid = Context.Session["RoleId"] == null ? "0" : Context.Session["RoleId"].ToString();
var uid = Context.Session["UserId"] == null ? "0" : Context.Session["UserId"].ToString();
if (searchIn.Equals(""))

{
rows = Operator.Contains("%") ? table.DefaultView.ToTable(true).Select(searchIn + " like '" + Operator.Replace("_", searchString) + "'", searchIn + " ASC") : table.DefaultView.ToTable(true).Select(searchIn + " " + Operator + " '" + searchString + "'", searchIn + " ASC");
