❔ Blazor - Get objects from child components

I have a page called "FactorSearch", that calls 2 instances of the same component, called "scope". Scope has 4 properties: Region, Universe, StartDate, EndDate. What I'm trying to do is, when I click "GetScope", I get an instance of the object Scope filled with the informations within each of the instances I created. Been trying to search about it but no success. Thanks!

In your page, create 2 reference variables correlating to that component you would want to initialize and add a @ ref to them So something like

 cs 
<ComponentA @ref="@_ref1" />
<ComponentA @ref="@_ref2"/>

@code{
private ComponentA _ref1;
private ComponentA _ref2;

//Do something with references here
}

 cs 
<ComponentA @ref="@_ref1" />
<ComponentA @ref="@_ref2"/>

@code{
private ComponentA _ref1;
private ComponentA _ref2;

//Do something with references here
}

Note that this can cause performance issues depending on how tightly coupled you want your component to be to your parent
