As a tech professional working with TypeScript, you may often come across the need to use the Mat-Paginator inside a child component, while the Mat-Table is located in the parent component. This scenario can be a bit tricky to handle, but fear not! In this blog post, we will explore multiple solutions to this problem, providing you with the code snippets you need to implement them in your own projects.

Solution 1: Using @ViewChild

One way to solve this problem is by using the @ViewChild decorator in Angular. This decorator allows you to access a child component from the parent component. Here’s how you can implement it:


    // Parent Component
    import { Component, ViewChild } from '@angular/core';
    import { ChildComponent } from './child.component';

    @Component({
      selector: 'app-parent',
      template: `
        
        
      `
    })
    export class ParentComponent {
      @ViewChild(ChildComponent) childComponent: ChildComponent;
    }

    // Child Component
    import { Component } from '@angular/core';
    import { MatPaginator } from '@angular/material/paginator';

    @Component({
      selector: 'app-child',
      template: `
        
      `
    })
    export class ChildComponent {
      @ViewChild(MatPaginator) paginator: MatPaginator;
    }

In this solution, we use the @ViewChild decorator in the parent component to access the child component. Then, we can access the MatPaginator instance in the child component using the same decorator. This allows us to use the MatPaginator inside the child component, even though the MatTable is located in the parent component.

Solution 2: Using Input and Output

Another approach to solving this problem is by using input and output properties to pass data between the parent and child components. Here’s how you can do it:


    // Parent Component
    import { Component } from '@angular/core';

    @Component({
      selector: 'app-parent',
      template: `
        
        
      `
    })
    export class ParentComponent {
      paginator: MatPaginator;
    }

    // Child Component
    import { Component, Input } from '@angular/core';
    import { MatPaginator } from '@angular/material/paginator';

    @Component({
      selector: 'app-child',
      template: `
        
      `
    })
    export class ChildComponent {
      @Input() paginator: MatPaginator;
    }

In this solution, we pass the MatPaginator instance from the parent component to the child component using an input property. Then, we bind this input property to the MatPaginator in the child component’s template. This allows us to use the MatPaginator inside the child component, even though the MatTable is located in the parent component.

Conclusion

There you have it! Two different solutions to the problem of using Mat-Paginator inside a child component when the Mat-Table is inside the parent component. Whether you prefer using @ViewChild or input/output properties, you now have the knowledge and code snippets to implement these solutions in your own TypeScript projects. Happy coding!
