Creating a Quick Grid Component in Blazor

Introduction:

Blazor is an open-source web framework for building web applications using .NET and C#. It allows developers to create web applications with a rich user interface using a combination of HTML, CSS, and C#. Blazor provides a powerful set of components that can be used to build complex user interfaces. In this how-to guide, we will explore how to create a Quick Grid component in Blazor that can be used to display data in a grid format.

Step 1: Create the Quick Grid component

To create the Quick Grid component, we need to define a new component in our Blazor application. Add the following code to a new Razor component file:

less

<table class="quick-grid">

  <thead>

    <tr>

      @foreach (var column in Columns)

      {

        <th>@column</th>

      }

    </tr>

  </thead>

  <tbody>

    @foreach (var item in Items)

    {

      <tr>

        @foreach (var column in Columns)

        {

          <td>@item[column]</td>

        }

      </tr>

    }

  </tbody>

</table>

 

This code defines a new component named QuickGrid and uses a table element to display the data in a grid format. The component has two properties named Columns and Items, which are used to define the columns and data for the grid.

Step 2: Define the columns and data for the grid

Once we have defined the Quick Grid component, we can use it to display data in a grid format. To do this, we need to define the columns and data for the grid. Add the following code to a component that uses the Quick Grid component:

perl

<QuickGrid Columns="@new[] { "Name", "Age" }" Items="@people" />

This code creates a new Quick Grid component and sets the Columns property to an array of strings representing the column headers for the grid. It also sets the Items property to a collection of objects representing the data for the grid.

Step 3: Style the Quick Grid component

To make the Quick Grid component look better, we can add some styles to the component. Add the following code to a CSS file in your project:

css

.quick-grid {

  border-collapse: collapse;

}

 

.quick-grid th, .quick-grid td {

  border: 1px solid black;

  padding: 5px;

}

This code adds some basic styles to the Quick Grid component, including a collapsed border and some padding for the cells.

Use case:

Let's say we have a Blazor application that displays a list of people. Each person has a name and an age. By using the Quick Grid component, we can display the list of people in a grid format.

For example, we can create a component that retrieves the list of people from a data source and passes the list to the Quick Grid component. Here's an example of what the code might look like:

less

@page "/people"

 

@inject IPeopleService PeopleService

 

<h1>People</h1>

 

<QuickGrid Columns="@new[] { "Name", "Age" }" Items="@people" />

 

@code {

  private List<Person> people;

 

  protected override async Task OnInitializedAsync()

  {

    people = await PeopleService.GetPeopleAsync();

  }

}

This code defines a component that displays the list of people in a Quick Grid component. The component uses an injected service named PeopleService to retrieve the list of people and sets the Columns and Items properties of the Quick Grid component.

Conclusion:

The Quick Grid component is a simple and flexible way to display data in a grid format in Blazor applications. By following the steps outlined in this how-to guide, we can create a Quick Grid component that can be used to display data in a grid format. We saw how to define the Quick Grid component, define the columns and data for the grid, and style the component.

We also saw a use case for the Quick Grid component, where we can use the component to display a list of people in a grid format. By using the Quick Grid component, we can create more complex and powerful user interfaces in Blazor applications.

We hope you found this guide on Creating a Quick Grid Component in Blazor insightful and valuable.
