How Load Data on Demand Feature Helps in Blazor Grid?

Blazor DataGrid Load on Demand feature helps you to load data as you need instead of loading all the data at once. This can be achieved either by using the AllowPaging or EnableVirtualization property and the SfDataManager with Adaptor.

We have provided support for different Adaptors namely (WebAPI, OData, ODataV4, Url etc.) to load data from different services to the grid with on demand loading concept / server-side paging. These adaptors use on demand loading concept to fetch data from server when the Paging feature is enabled.

To bind remote data to the DataGrid component, assign the service data as an instance of the SfDataManager to the DataSource property or by using the SfDataManager component. To interact with remote data source, we need to provide the endpoint Url.

Refer to the following code example.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Data
@using Syncfusion.Blazor.Grids
 
@* Enable AllowPaging to load the data on demand *@
 
<SfGrid TValue="Order" AllowPaging="true">
<SfDataManager Url="https://js.syncfusion.com/ejServices/Wcf/Northwind.svc/Orders" Adaptor="Adaptors.ODataAdaptor"></SfDataManager>
<GridColumns>
