To pass an ID from one component to another in Blazor, you can use route parameters or component parameters. Here are two common approaches:

1. Using Route Parameters:

   With this approach, you can define a route template that includes a parameter for the ID in the `RouteView` or `RouteViewRoute` component. The ID value will be part of the URL, and the receiving component can access it through a parameter.

   In the source component, navigate to the target component by specifying the ID in the URL:

   csharp

   NavigationManager.NavigateTo($"targetcomponent/{id}");

   

   In the target component, define a route template with a parameter for the ID:

   razor

   <RouteView RouteData="@routeData" DefaultLayout="typeof(MainLayout)">

       <RouteViewRoute RouteTemplate="targetcomponent/{id:int}" RouteData="@routeData" DefaultLayout="typeof(MainLayout)" />

   </RouteView>

   @code {

       [Parameter] public RouteData routeData { get; set; }

   }

   

   In the target component's code, you can access the ID through the `routeData` parameter:

   csharp

   var id = routeData.Values["id"];

   

2. Using Component Parameters:

   With this approach, you can pass the ID as a parameter from the source component to the target component.

   In the source component, use the target component and pass the ID as a parameter:

   razor

   <TargetComponent Id="@id" />

   

   In the target component, define a property for the ID as a component parameter:

   razor

   <h3>@Id</h3>

   @code {

       [Parameter] public int Id { get; set; }

   }

   

   In this example, the ID value is passed from the source component to the `TargetComponent` using the `Id` parameter. The target component can then use the ID for rendering or any other operations.

These approaches allow you to pass an ID from one component to another in Blazor. Choose the approach that best suits your application's needs based on the relationship between the components and how you want to structure your routing and component hierarchy.
