Copy to clipboard by external buttons

To copy selected rows or cells data into clipboard with help of external buttons, you need to invoke the copy method.

app.component.ts
main.ts
import { NgModule,ViewChild } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { TreeGridModule } from '@syncfusion/ej2-angular-treegrid'

    }

    copy() {
        (this.treeGridObj as TreeGridComponent).copy();
    }

    }
}

Copy Hierarchy Modes

Tree Grid provides support for a set of copy modes with copyHierarchyMode property. The below are the type of filter mode available in TreeGrid.

Parent : This is the default copy hierarchy mode in Tree Grid. Clipboard value have the selected records with its parent records. If the selected records not have any parent record then the selected record will be in clipboard.
Child : Clipboard value have the selected records with its child record. If the selected records do not have any child record then the selected records will be in clipboard.
Both : Clipboard value have the selected records with its both parent and child record. If the selected records do not have any parent and child record then the selected records alone in clipboard.
None : Only the Selected records will be in clipboard.

Limitations of Copy Functionality

Only current view records will be available in copy clipboard.

AutoFill

AutoFill Feature allows you to copy the data of selected cells and paste it to another cells by just dragging the autofill icon of the selected cells up to required cells. This feature is enabled by defining enableAutoFill property as true.

import { NgModule,ViewChild } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { TreeGridModule } from '@syncfusion/ej2-angular-treegrid'

import { SelectionSettingsModel, EditSettingsModel, ToolbarItems } from '@syncfusion/ej2-angular-treegrid';

@Component({
imports: [
        
        TreeGridModule,
        ButtonModule,
        DropDownListAllModule,
    ],

providers: [PageService,
                SortService,
                FilterService,
                EditService,
                ToolbarService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-treegrid #treegrid [dataSource]='data' [enableAutoFill]='true'  [enableHover]='false' [allowPaging]='true' [pageSettings]='pageSettings' [editSettings]='editSettings' [allowSelection]='true' [toolbar]='toolbar' [selectionSettings]='selectionOptions' height='220' childMapping='subtasks' [treeColumnIndex]='1'>

})
export class AppComponent implements OnInit {

    public data?: Object[];
    public selectionOptions?: SelectionSettingsModel;
    public editSettings?: EditSettingsModel;
    public pageSettings?: Object ;
    public toolbar?: ToolbarItems[];

    ngOnInit(): void {
        this.data = sampleData;
        this.selectionOptions = { type: 'Multiple', mode: 'Cell', cellSelectionMode: 'Box' };
        this.editSettings= { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Batch' },
        this.toolbar = ['Add', 'Update', 'Cancel'];
        this.pageSettings = {pageSize: 10};
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

If enableAutoFill is set to true, then the autofill icon will be displayed on cell selection to copy cells.

It requires the selection mode to be Cell, cellSelectionMode to be Box and also Batch Editing should be enabled.

Limitations of AutoFill

Since the string values are not parsed to number and date type, so when the selected string type cells are dragged to number type cells then it will display as NaN. For date type cells, when the selected string type cells are dragged to date type cells then it will display as an empty cell.
Linear series and the sequential data generations are not supported in this autofill feature.

Paste

You can able to copy the content of a cell or a group of cells by selecting the cells and pressing Ctrl + C shortcut key and paste it to another set of cells by selecting the cells and pressing Ctrl + V shortcut key.

Paste the cell programmatically by using the Paste method in the tree grid. To use, you need to pass the data to paste the row index and column index as parameters to the method.

To perform paste functionality, it requires the selection mode to be Cell, cellSelectionMode to be Box and also Batch Editing should be enabled.

Limitations of Paste Functionality

Since the string values are not parsed to number and date type, so when the copied string type cells are pasted to number type cells then it will display as NaN. For date type cells, when the copied string format cells are pasted to date type cells then it will display as an empty cell.
