When working with Blazor, you can call child component methods from a parent component by using component references. This allows you to communicate between different components and trigger actions in the child component.

To achieve this, you need to follow these steps:

  1. Create a public method in the child component that you want to call from the parent component.
  2. In the parent component, use the `@ref` directive to create a component reference to the child component.
  3. Access the child component’s public method using the component reference and call it as needed.

Here’s an example to illustrate this:

@* Child Component Markup *@

ChildComponent.razor

@code {
private int counter = 0;

public void IncrementCounter()
{
counter++;
}
}

@* Parent Component Markup *@

ParentComponent.razor

@code {
private ChildComponent childComponent;

public void CallChildMethod()
{
childComponent.IncrementCounter();
}
}

“`

In the above example, we have a parent component (`ParentComponent.razor`) and a child component (`ChildComponent.razor`). The child component exposes a public method called `IncrementCounter()` which increments a counter variable. The parent component creates a component reference to the child component using the `@ref` directive, allowing it to access the child component’s public method. When the “Call Child Method” button is clicked in the parent component, it calls the `IncrementCounter()` method of the child component, thus incrementing the counter variable.

Note: In this example, the HTML content is wrapped in an outer `
