  • How to bind employees data to table/grid.

 

Solution Structure

Step 1: Create a Models folder and create Employee.cs class

using System;

namespace BlazorAppDemo1.Models
{
    public class Employee
    {
        public int EmployeeId { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public DateTime DateOfBirth { get; set; }
        public string Mobile { get; set; }
        public string Country { get; set; }
    }
}

Step 2: Add new Razor Component to Pages folder

Step 3: Name the Razor Component as Employee.razor.

Step 4: Add page url "/employees", inherit the employee razor component from ComponentBase as below.

@page "/employees"
@inherits ComponentBase

Step 5: Open NavMenu.razor page which is under the Shared folder.

Step 6: Add a new nav link for employees as below.

<li class="nav-item px-3">
    <NavLink class="nav-link" href="/employees">
        <span class="oi oi-list-rich" aria-hidden="true"></span> Employees
    </NavLink>
</li>

Step 7: Declare employees variable to hold the employee's collection.

@page "/employees"
@inherits ComponentBase
@using Models;


....


@code {
    private List<Employee> employees;
}

Step 8: OnInitialized() bind employees data to bind to the table.

@page "/employees"
@inherits ComponentBase
@using Models;


....

@code {
    private List<Employee> employees;

    protected override void OnInitialized()
    {
    	// TODO: do something
    }
}

@code {
    private List<Employee> employees;

    protected override void OnInitialized()
    {
        employees = new List<Employee>
        {
            new Employee{
                EmployeeId = 101,
                FirstName="Badri Ayaan",
                LastName="Reddy",
                DateOfBirth = DateTime.Now.AddYears(-20),
                Mobile = "9988776655",
                Country = "India"
            },
            new Employee{
                EmployeeId = 102,
                FirstName="Nithya Vikram",
                LastName="Reddy",
                DateOfBirth = DateTime.Now.AddYears(-18),
                Mobile = "8877665544",
                Country = "India"
            }
        };
    }
}

Step 9: Loop through the employees collection and render the table rows.

<h3>Employees</h3>
@if (employees == null)
{
    <p>Loading Employees...</p>
}
else
{
    <table class="table table-sm">
        <thead>
            <tr>
                <th scope="col">#</th>
                <th scope="col">Id</th>
                <th scope="col">First Name</th>
                <th scope="col">Last Name</th>
                <th scope="col">DOB</th>
                <th scope="col">Mobile</th>
                <th scope="col">Country</th>
            </tr>
        </thead>
        <tbody>

            @{
                var index = 1;
                foreach (var item in employees)
                {
                    <tr>
                        <th scope="row">@index</th>
                        <td>@item.EmployeeId</td>
                        <td>@item.FirstName</td>
                        <td>@item.LastName</td>
                        <td>@item.DateOfBirth</td>
                        <td>@item.Mobile</td>
                        <td>@item.Country</td>
                    </tr>
                    index++;
                }
            }
        </tbody>
    </table>
}
