MVC multiple field search with webgrid - Step 5

First of all we will try for multiple field search with paging and sorting for products by using WebGrid. We will create relationship between products and category table so we can show the category name in grid. To search we need a separate model for search having all the paging, sorting, total records and products. We need full featured page to search records by providing product name, price and category. After searching the records it should have the sorting feature by clicking the column name in grid as well as paging.

Main problem with paging and sorting we face is to sorting and paging with multiple field search. Suppose we entered product name and price and selected some category and search the result, now if we will try tp sort the result by clicking grid column, or click on any page number, we will loss all the search criteria. So solve it we will use FormMethod.Get, we will see it latter in this article.

First we will modify our products model to have property to save images and relationship with category.

public class Product
    public Int32 ProductId { get; set; }

    [Display(Name="Product Name")]
    public String ProductName { get; set; }

    [Display(Name = "Price")]
    public Decimal Price { get; set; }

    [Display(Name = "Category")]
    public Int32 CategoryId { get; set; }

    public String Image { get; set; }

    public String Thumb { get; set; }

    public virtual Category Categories { get; set; } 

See the last property with virtual keyword, it is used to create the relationship between tables.

Now we will create the model for search with name "ProductSearchModels" having all the columns we want to search and properties like page, page size, sort column, sort direction, total number of records etc.

public class ProductSearchModels
    [Display(Name = "Product Name")]
    public String ProductName { get; set; }

    [Display(Name = "Price (Max.)")]
    public Decimal? Price { get; set; }

    [Display(Name = "Category")]
    public Int32? Category { get; set; }

    public Int32 Page { get; set; }
    public Int32 PageSize { get; set; }
    public String Sort { get; set; }
    public String SortDir { get; set; }
    public Int32 TotalRecords { get; set; }
    public List<Product> Products { get; set; }

    public ProductSearchModels()
        Page = 1;
        PageSize = 5;
        Sort = "ProductId";
        SortDir = "DESC";

We added all the columns which we want to search and the other properties like page, pagesize, sort and sortdir are default properties from gridview so I try to keep them same. At the end we have constructor of the class to assign default values like sort column, sort direction, current page and page size.

Create a new empty controller named "ProductsController" and add a private member db to access the database

private LearningContext db = new LearningContext();

When we add an empty controller, by default it adds Index action method, if not then add it manually and add the following code in it

public ActionResult Index(ProductSearchModels model)
    // To Bind the category drop down in search section
    ViewBag.Categories = db.Categories.Where(x => x.IsActive == true);

    // Get Products
    model.Products = db.Products
            (model.ProductName == null || x.ProductName.Contains(model.ProductName))
            && (model.Price == null || x.Price < model.Price)
            && (model.Category == null || x.CategoryId == model.Category)
        .OrderBy(model.Sort + " " + model.SortDir)
        .Skip((model.Page - 1) * model.PageSize)

    // total records for paging
    model.TotalRecords = db.Products
        .Count(x =>
            (model.ProductName == null || x.ProductName.Contains(model.ProductName))
            && (model.Price == null || x.Price < model.Price)
            && (model.Category == null || x.CategoryId == model.Category)

    return View(model);

OrderBy will give error because I used here dynamic sorting, to make it working we need to install "System.Linq.Dynamic.Library", open package manage and run "Install-Package System.Linq.Dynamic.Library".

First part of the code is used to get products and next to get the total records count.

Let's create view for it

  • Right click inside the index action
  • Click Add View
  • View Name: Index
  • Template: Empty
  • Model Class: ProductSearchModels (Advance.Learning.WebApp.Models)
  • Data Context Class: blank
  • Uncheck: Create as a partial view
  • Check: Reference script library
  • Check: Use a layout page
  • provide the layout name: ~/Views/Shared/_Layout.cshtml
  • Click Add

alt text

It will create a blank view with basic model and layout settings, update it with following code

@model Advance.Learning.WebApp.Models.ProductSearchModels
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
<h1>Search Product</h1>

@using (Html.BeginForm("index", "products", FormMethod.Get))
<div class="row">

    <div class="form-horizontal">
        <div class="col-lg-3">
            @Html.TextBoxFor(m => m.ProductName, new { @class = "form-control", @placeholder = "Product Name" })
        <div class="col-lg-3">
            @Html.TextBoxFor(m => m.Price, new { @class = "form-control", @placeholder = "Price (max.)" })
        <div class="col-lg-3">
            @Html.DropDownListFor(m => m.Category, new SelectList(ViewBag.Categories, "CategoryId", "CategoryName"), 
                   "All Categories", new { @class = "form-control", @placeholder = "Category" })

        <div class="col-lg-3">
            <button type="submit" class="btn btn-success">
                <span class="glyphicon glyphicon-search"></span>

            <a class="btn btn-success pull-right" data-modal="" href="/Products/Create" id="btnCreate">
                <span class="glyphicon glyphicon-plus"></span>

<div style="margin-top:17px;">
var grid = new WebGrid(
                    canPage: true,
                    rowsPerPage: Model.PageSize,
                    canSort: true,
                    ajaxUpdateContainerId: "grid");

grid.Bind(Model.Products, rowCount: Model.TotalRecords, autoSortAndPage: false);

@grid.GetHtml(htmlAttributes: new { id = "grid" },  
        fillEmptyRows: false,
        tableStyle: "table table-bordered table-hover",
        mode: WebGridPagerModes.All,
        columns: grid.Columns(
              grid.Column("ProductId", "ID"),
              grid.Column("ProductName", "ProductName", style: "col-lg-6"),
              grid.Column("Price", header: "Price", format: @<text>@String.Format("{0:C}", item.Price) </text>),
              grid.Column("Categories.CategoryName", "Category", style: "col-lg-2"),
              grid.Column(header: "Action", canSort: false, style: "action",
                format: @<text>
                @Html.Raw("<a data-modal='' href='/products/details/" + item.ProductId + "' id='" + item.ProductId + "' title='Detail'> <span class='glyphicon glyphicon-search'> </span> </a>")
                @Html.Raw("<a data-modal='' href='/products/edit/" + item.ProductId + "' id='" + item.ProductId + "' title='Edit'> <span class='glyphicon glyphicon-edit'> </span> </a>")
                @Html.Raw("<a data-modal='' href='/products/delete/" + item.ProductId + "' id='" + item.ProductId + "' title='Delete'> <span class='glyphicon glyphicon-trash'> </span> </a>")

Here note @using (Html.BeginForm("index", "products", FormMethod.Get)), remove all the parameters in BeginForm and run the application and search result by providing some values and change page number or sort the record, we will loss all the search criteria, that's why I used FormMethod.Get so it will add the search criteria, paging and sorting into url as a query string and will work smooth.

grid.Column("Categories.CategoryName", "Category", style: "col-lg-2"),

Might be you noticed the binding Categories.CategoryName, it is not in our model show how we can bind it, correct, we created our table to link with category so we can access that table values directly, that's why this line works and bind the category name into our webgrid.

I cannot see anything new which I need to explain, let me know if anyone want to explain any part of the code which can help other to understand the code easily.
