How to bind this context to child grid

[James Evangelist]

Hi,

is there any way to bind 'this' context of my component to child grid?

Example - I've got code for parent grid defined on TypeScript side like this: 

private childGrid: ChildGrid = {

     editSettings: { /*someSettings*/ },

     actionComplete (args: any) {

          // here I want to have 'this' context of my component to save data when this event triggers

     }

     /* more config */

}

Hopefully, you can understand what I want to achieve.

Hi James,  

Thanks for contacting Syncfusion support  

Query: “is there any way to bind 'this' context of my component to child grid?” 

From your query, we suspect that you want to get the parent Grid details (component instance) inside the childGrid actionComplete event. We have achieved your requirement by binding the this argument along with actionComplete event. Refer the below code example 

    <ejs-grid #Grid id='Grid' [dataSource]='parentData' [childGrid]='childGrid'> 

        <e-columns> 

…………………………………………. 

        </e-columns> 

    </ejs-grid> 

 

…………………………………………… 

 

export class AppComponent { 

    @ViewChild('Grid') 

    public appGrid: GridComponent; 

      public parentData: Object[]; 

      public childGrid: any; 

      public secondChildGrid: any; 

   

   

      ngOnInit(): void { 

          this.parentData = employeeData;        

          this.childGrid = { 

              dataSource: orderDatas, 

              queryString: 'EmployeeID', 

              allowPaging: true, 

              actionComplete: onComplete.bind(this), 

              editSettings: {allowEditing: true}, 

              pageSettings: {pageSize: 6, pageCount: 5}, 

              columns: [ 

                  { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 120 }, 

                  { field: 'ShipCity', headerText: 'Ship City', width: 120 }, 

                  { field: 'Freight', headerText: 'Freight', width: 120 }, 

                  { field: 'ShipName', headerText: 'Ship Name', width: 150 } 

              ]            

          }; 

      } 

  } 

  function onComplete(args){ 

    let proxy  = this // this reutns appcomponent instance 

    this.appGrid; //here you can get the parent Grid instance.  

  }
