Getting started with Blazor Pager Component in Blazor Web App
29 Nov 202412 minutes to read
This section briefly explains about how to include Blazor Pager
component in your Blazor Web App using Visual Studio.
Prerequisites
Create a new Blazor Web App
You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion® Blazor Extension.
You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.
Install Syncfusion® Blazor Navigations and Themes NuGet in the App
To add Blazor Pager component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.Navigations and Syncfusion.Blazor.Themes.
If you utilize WebAssembly or Auto
render modes in the Blazor Web App need to be install Syncfusion® Blazor components NuGet packages within the client project.
Alternatively, you can utilize the following package manager command to achieve the same.
Install-Package Syncfusion.Blazor.Navigations -Version 28.1.33
Install-Package Syncfusion.Blazor.Themes -Version 28.1.33
NOTE
Syncfusion® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.
Register Syncfusion® Blazor Service
Open ~/_Imports.razor file and import the Syncfusion.Blazor
and Syncfusion.Blazor.Navigations
namespace .
@using Syncfusion.Blazor
@using Syncfusion.Blazor.Navigations
Now, register the Syncfusion® Blazor Service in the ~/Program.cs file of your Blazor Web App.
If you select an Interactive render mode as WebAssembly
or Auto
, you need to register the Syncfusion® Blazor service in both ~/Program.cs files of your Blazor Web App.
....
using Syncfusion.Blazor;
....
builder.Services.AddSyncfusionBlazor();
....
Add stylesheet and script resources
The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet reference in the <head>
section and the script reference at the end of the <body>
in the ~/Components/App.razor file as shown below:
<head>
....
<link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>
<body>
....
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>
NOTE
Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.
Add Blazor Pager component
Here, the Pager component is integrated with the ListView component. So, the first ListView component is added in the ~Pages/.razor file. Refer here to create the Syncfusion® ListView component.If an interactivity location as Per page/component
in the web app, define a render mode at the top of the ~Pages/.razor
component, as follows:
@* desired render mode define here *@
@rendermode InteractiveAuto
@using Syncfusion.Blazor.Navigations
@using Syncfusion.Blazor.Lists
<SfListView DataSource="@ListData" TValue="DataModel">
<ListViewFieldSettings TValue="DataModel" Id="Id" Text="Name"></ListViewFieldSettings>
</SfListView>
@code {
List<DataModel> ListData = new List<DataModel>();
protected override void OnInitialized()
{
base.OnInitialized();
ListData.Add(new DataModel { Name = "Nancy, Berlin, France" });
ListData.Add(new DataModel { Name = "Andrew, Madrid, Germany" });
ListData.Add(new DataModel { Name = "Janet, London, Brazil" });
ListData.Add(new DataModel { Name = "Margaret, Marseille, Belgium" });
ListData.Add(new DataModel { Name = "Steven, Cholchester, Switzerland" });
ListData.Add(new DataModel { Name = "Laura , Tsawassen, Venezuela" });
ListData.Add(new DataModel { Name = "Robert, Tacoma, Austria" });
ListData.Add(new DataModel { Name = "Michael, Redmond, Mexico" });
ListData.Add(new DataModel { Name = "Albert, Kirkland, USA" });
ListData.Add(new DataModel { Name = "Nolan, London, Sweden" });
ListData.Add(new DataModel { Name = "Jennifer, Berlin, Finland" });
ListData.Add(new DataModel { Name = "Carter, Madrid, Italy" });
ListData.Add(new DataModel { Name = "Allison, Marseille, Spain" });
ListData.Add(new DataModel { Name = "John, Tsawassen, UK" });
ListData.Add(new DataModel { Name = "Susan, Redmond, Ireland" });
ListData.Add(new DataModel { Name = "Lydia, Cholchester, Portugal" });
ListData.Add(new DataModel { Name = "Kelsey, London, Canada" });
ListData.Add(new DataModel { Name = "Jessica, Kirkland, Denmark" });
ListData.Add(new DataModel { Name = "Robert, Berlin, Austria" });
ListData.Add(new DataModel { Name = "Shelley, Tacoma, Poland" });
ListData.Add(new DataModel { Name = "Vanjack, Tsawassen, Norway" });
ListData.Add(new DataModel { Name = "shelley, Cholchester, Argentina" });
ListData.Add(new DataModel { Name = "Lydia, Kirkland, Finland" });
ListData.Add(new DataModel { Name = "Jessica, Madrid, Sweden" });
ListData.Add(new DataModel { Name = "Nolan, London, UK" });
ListData.Add(new DataModel { Name = "Jennifer, Redmond, Italy" });
}
public class DataModel
{
public string Name { get; set; }
public string Id { get; set; }
}
}
In the previous sample, the list view items are rendered. The Pager component provides an option to split this list view data set into sectioned pages and view them page by page. So, the Pager component is added in the ~Pages/.razor file as follows.
@using Syncfusion.Blazor.Navigations
<SfPager PageSize=5 NumericItemsCount=4 TotalItemsCount=25>
</SfPager>
Based on the PageSize property of the pager, the list view items are bound to the current page. In the following code sample, the PageSize
is defined as “5” so that the first five items from the data source of the list view will be displayed on the current page using the Skip and Take values.
@using Syncfusion.Blazor.Data
@using Syncfusion.Blazor.Navigations
@using Syncfusion.Blazor.Lists
<div class="col-lg-12 control-section sb-property-border">
@{
var listData = ListData.Skip(SkipValue).Take(TakeValue).ToList();
<SfListView DataSource="@listData" TValue="DataModel" HeaderTitle="Contacts" ShowHeader="true">
<ListViewFieldSettings TValue="DataModel" Id="Id" Text="Name"></ListViewFieldSettings>
</SfListView>
}
<SfPager PageSize=5 NumericItemsCount=4 TotalItemsCount=25>
</SfPager>
</div>
@code {
public int SkipValue;
public int TakeValue = 5;
List<DataModel> ListData = new List<DataModel>();
protected override void OnInitialized()
{
base.OnInitialized();
ListData.Add(new DataModel { Name = "Nancy, Berlin, France" });
ListData.Add(new DataModel { Name = "Andrew, Madrid, Germany" });
ListData.Add(new DataModel { Name = "Janet, London, Brazil" });
ListData.Add(new DataModel { Name = "Margaret, Marseille, Belgium" });
ListData.Add(new DataModel { Name = "Steven, Cholchester, Switzerland" });
ListData.Add(new DataModel { Name = "Laura , Tsawassen, Venezuela" });
ListData.Add(new DataModel { Name = "Robert, Tacoma, Austria" });
ListData.Add(new DataModel { Name = "Michael, Redmond, Mexico" });
ListData.Add(new DataModel { Name = "Albert, Kirkland, USA" });
ListData.Add(new DataModel { Name = "Nolan, London, Sweden" });
ListData.Add(new DataModel { Name = "Jennifer, Berlin, Finland" });
ListData.Add(new DataModel { Name = "Carter, Madrid, Italy" });
ListData.Add(new DataModel { Name = "Allison, Marseille, Spain" });
ListData.Add(new DataModel { Name = "John, Tsawassen, UK" });
ListData.Add(new DataModel { Name = "Susan, Redmond, Ireland" });
ListData.Add(new DataModel { Name = "Lydia, Cholchester, Portugal" });
ListData.Add(new DataModel { Name = "Kelsey, London, Canada" });
ListData.Add(new DataModel { Name = "Jessica, Kirkland, Denmark" });
ListData.Add(new DataModel { Name = "Robert, Berlin, Austria" });
ListData.Add(new DataModel { Name = "Shelley, Tacoma, Poland" });
ListData.Add(new DataModel { Name = "Vanjack, Tsawassen, Norway" });
ListData.Add(new DataModel { Name = "shelley, Cholchester, Argentina" });
ListData.Add(new DataModel { Name = "Lydia, Kirkland, Finland" });
ListData.Add(new DataModel { Name = "Jessica, Madrid, Sweden" });
ListData.Add(new DataModel { Name = "Nolan, London, UK" });
ListData.Add(new DataModel { Name = "Jennifer, Redmond, Italy" });
}
public class DataModel
{
public string Name { get; set; }
public string Id { get; set; }
}
}
Through the navigation of the pager items, view the items in the list view page by page. This can be achieved by using the ItemClick
event of the Pager. In the ItemClick
event of the Pager, the SkipValue and TakeValue are calculated using the PageSize
property and arguments of the ItemClick
event (CurrentPage, PreviousPage). Based on these details, view the items in the list view page by page.
