How to make child component to be rendered in parent component? #1782

Both of the parent and child component use the same int array object.

If I change the array in the parent component, the child component has to be rendered again.

How can I do this?

I was tried to bind the object to child component, however it said that cannot bind array object.

I believe you want to pass the array to child component and render it there.

child component (child.cshtml)

@if(TTypeNames ==null)
// some html to say it's loading 
}else if(TTypeNames.Count ==0)
//  // some html to say it's empty
foreach(var item in TTypeNames )
// html

@functions {   
    [Parameter] List<TType> TTypeNames { get; set; }
    protected override async Task OnParametersSetAsync()

now in your parent component you can pass data like this

<child TTypeNames ="@TTypeList"></child>

better to go through this blazor workshop it explains everything in awesome way.
