Doubt regarding manual paging.
posted

Hello everyone,

So, i want to perform manual paging where i bring data in pages only when user change the page number. I m unable to perform this. Please help me out with this.

note : In below code i have not enabled manual paging as i m confused how to extract parameter from query string and how to bring data only when user switch pages.(server side paging)

Code:

@using Infragistics.Web.Mvc;
@using System.Text.Json

@*@model IEnumerable<GridTransaction.Models.Student>*@
@* The Ignite UI for MVC Grid data source uses LINQ and therefore only accepts instances of IQueryable<T>.
Even when you opt to use the GridMode you will explicitly set the DataSource property which
requires an instance of IQueryable<T> .*@

<head>

<body>

@* @(
Html.Infragistics().Grid(Model).ID("grid").PrimaryKey("Id").AutoGenerateColumns(false).Width("100%").AutoCommit(false)

.Columns(columns =>
{
columns.For(model => model.Id).DataType("number").HeaderText("Student ID").Width("15%");
columns.For(model => model.Name).DataType("string").HeaderText("Student Name").Width("30%");
columns.For(model => model.Marks).DataType("number").HeaderText("Marks").Width("30%");
columns.For(model => model.subject).DataType("string").HeaderText("Subject").Width("15%");
columns.For(model => model.Imagepath).DataType("string").HeaderText("Imagepath").Template("<img src='${Imagepath}' width='50' height='50' />");

}).DataSource(Model)
// Set the data source URL
.Features(features =>
{
features.Selection().MultipleSelection(true);
features.GroupBy();
features.Paging().PageSize(10);
features.Updating();
features.Tooltips().Visibility(TooltipsVisibility.Always);// provide informaion about grid when you hover over
features.RowSelectors().EnableCheckBoxes(true);
features.RowSelectors().EnableRowNumbering(true);
features.Updating().EnableAddRow(true).EnableDeleteRow(true);

ASP CODE  TO HANDLE PAGING:

public JsonResult Data12()
{

var absolutepath1 = HttpContext.Request.QueryString.ToString();
var absolutepath = HttpContext.Request.Query["$orderby"].ToString();


Console.WriteLine(absolutepath1);

string[] m = absolutepath.Split(' ');
//foreach(var m2 in m)
//{
// Console.WriteLine(m2);
//}
// absolutepath.Remove("?");

var colname = m[0];
var orderb1y = m[1];

IEnumerable<Student> sat = data.sort(colname, orderb1y);

// IEnumerable<Student> students = data.GetStudents();


return Json(sat);

    Hello Rohit,

    In order for you to further test the sample and compare the different parts to your own project, i.e., igGrid configuration, required jQuery and Ignite UI for jQuery js and css files, custom paging methods configuration, etc., I am applying a working MVC project.

    Please review the code configuration, test it on your side and let me know if you need any further assistance regarding this matter.

    Sincerely,
