Drag and Drop list items

In ListView component, we don’t have drag and drop support. But we can achieve this requirement using TreeView component with ListView appearance.

Drag and Drop in TreeView component was enabled by setting allowDragAndDrop to true.

        <TreeViewComponent id='treeview'
                dataSource={this.data}
                allowDragAndDrop = {true}
                fields= {this.field} >
        </TreeViewComponent>

The TreeView component is used to represent hierarchical data in a tree like structure. So, list items in TreeView can be dropped to child of target element. we can prevent this behaviour by cancelling the nodeDragStop and nodeDragging events.

onDragStop(args: DragAndDropEventArgs) {
    //Block the Child Drop operation in TreeView
   let  draggingItem: HTMLCollection = document.getElementsByClassName("e-drop-in");
    if (draggingItem.length == 1) {
        draggingItem[0].classList.add('e-no-drop');
        args.cancel = true;
    }
}

render() {
        return (
        <TreeViewComponent id='treeview'
                dataSource={this.data}
                allowDragAndDrop = {true}
                nodeDragging = {this.onDragStop.bind(this)}
                nodeDragStop = {this.onDragStop.bind(this)}
                fields= {this.field} >
        </TreeViewComponent>
        )
    }
onDragStop(args, DragAndDropEventArgs);
{
    //Block the Child Drop operation in TreeView
    let draggingItem = document.getElementsByClassName("e-drop-in");
    if (draggingItem.length == 1) {
        draggingItem[0].classList.add('e-no-drop');
        args.cancel = true;
    }
}
render();
{
    return (<TreeViewComponent id='treeview' dataSource={this.data} allowDragAndDrop={true} nodeDragging={this.onDragStop.bind(this)} nodeDragStop={this.onDragStop.bind(this)} fields={this.field}>
        </TreeViewComponent>);
}

In the below sample, we have rendered draggable list items.
