According to the documentation, "Syncfusion Angular UI (Essential JS 2) is a collection of modern TypeScript based true Angular Components. It has support for Ahead Of Time (AOT) compilation and Tree-Shaking. All the components are developed from the ground up to be lightweight, responsive, modular, and touch-friendly."
In this article, we learn how to copy and paste a child/sibling row in Syncfusion Angular TreeGrid.
First, we create an angular project and add Syncfusion to the project using the getting started guide. For this example, I will use stackblitz.com and you can also start with some examples from documentation like this.
In this project, we will copy and paste the row function. To add a context menu to our project, in appcomponent.ts add the code below:
export class AppComponent {
public data: Object[] = [];
public contextMenuItems: Object;
ngOnInit(): void {
this.contextMenuItems = [
{ text: "Copy", target: ".e-content", id: "rcopy" },
{ text: "Paste Sibling", target: ".e-content", id: "rsibling" },
{ text: "Paste Child", target: ".e-content", id: "rchild" },
];
}
}In app.component.html, we change <ejs-treegrid ... >. The code is below.
<ejs-treegrid
#treegrid
[dataSource]="data"
allowPaging="true"
childMapping="subtasks"
height="350"
[treeColumnIndex]="0"
[contextMenuItems]="contextMenuItems"
(contextMenuOpen)="contextMenuOpen($event)"
(contextMenuClick)="contextMenuClick($event)"
[columns]="treeColumns"
>We will create contextMenuOpen function like the code below:
contextMenuOpen(arg?: BeforeOpenCloseEventArgs): void {
this.rowIndex = arg.rowInfo.rowIndex;
let elem: Element = arg.event.target as Element;
if (elem.closest('.e-row')) {
document
.querySelectorAll('li#rcopy')[0]
.setAttribute('style', 'display: block;');
document
.querySelectorAll('li#rsibling')[0]
.setAttribute('style', 'display: block;');
document
.querySelectorAll('li#rchild')[0]
.setAttribute('style', 'display: block;');
}
}For copying the row, we will create a copy function:
copy() {
this.copiedRow = this.treegrid.getRowByIndex(this.rowIndex);
this.treegrid.copyHierarchyMode = 'None';
this.treegrid.copy();
this.copiedRow.setAttribute('style', 'background:#FFC0CB;');
}In the contextMenuClick event function, we will check which button the user clicks. Then we copy the row or paste as a child or sibling depending on the value (code below).
contextMenuClick(args): void {
if (args.item.id == 'rsibling') {
var copyContent = this.treegrid.clipboardModule.copyContent;
var stringArray = copyContent.split('\t');
let newRecord: Treerow = new Treerow(
stringArray[0],
stringArray[1],
stringArray[2],
stringArray[3],
stringArray[4],
stringArray[5],
stringArray[6],
this.selectedRow.data.ParentItem
);
newRecord.children = [];
newRecord.isParent = true;
newRecord.id = uuidv4();
const body = {
TaskID: newRecord.TaskID,
TaskName: newRecord.TaskName,
StartDate: newRecord.StartDate,
EndDate: newRecord.EndDate,
Duration: newRecord.Duration,
Progress: newRecord.Progress,
Priority: newRecord.Priority,
isParent: newRecord.isParent,
ParentItem: newRecord.ParentItem,
};
this.http
.post<any>('https://vom-app.herokuapp.com/tasks', body)
.subscribe((data) => {
console.log('post:------------------', data);
this.dataManager
.executeQuery(new Query())
.then((e: ReturnOption) => (this.data = e.result.data as object[]))
.catch((e) => true);
});
this.dataManager
.executeQuery(new Query())
.then((e: ReturnOption) => (this.data = e.result.data as object[]))
.catch((e) => true);
this.copiedRow.setAttribute('style', 'background:white;');
}
if (args.item.id == 'rchild') {
var copyContent = this.treegrid.clipboardModule.copyContent;
var stringArray = copyContent.split('\t');
let newRecord: Treerow = new Treerow(
stringArray[0],
stringArray[1],
stringArray[2],
stringArray[3],
stringArray[4],
stringArray[5],
stringArray[6],
this.selectedRow.data.TaskID
);
newRecord.children = [];
newRecord.isParent = false;
newRecord.id = uuidv4();
const body = {
TaskID: newRecord.TaskID,
TaskName: newRecord.TaskName,
StartDate: newRecord.StartDate,
EndDate: newRecord.EndDate,
Duration: newRecord.Duration,
Progress: newRecord.Progress,
Priority: newRecord.Priority,
isParent: newRecord.isParent,
ParentItem: newRecord.ParentItem,
};
this.http
.post<any>('https://vom-app.herokuapp.com/tasks', body)
.subscribe((data) => {
console.log('post:------------------', data);
this.dataManager
.executeQuery(new Query())
.then((e: ReturnOption) => (this.data = e.result.data as object[]))
.catch((e) => true);
});
this.copiedRow.setAttribute('style', 'background:white;');
}
else if (args.item.id === 'rcopy') {
this.MultiSelect = true;
this.editSettings = {
allowEditing: true,
allowAdding: true,
allowDeleting: true,
newRowPosition: 'Child',
mode: 'Batch',
};
this.copiedRow = this.treegrid.getRowByIndex(this.rowIndex);
this.treegrid.copyHierarchyMode = 'None';
this.treegrid.copy();
this.copiedRow.setAttribute('style', 'background:#FFC0CB;');
}
}Now our app can copy a row and paste it as a child or sibling to the other row like in the image below:
To sum up, in this project, we learned how to use the copy/paste function for pasting as a child or sibling to another row in Syncfusion Angular TreeGrid. You can find the code here.
