How to perform Drag and Drop operation in OrgChart
In the Orgchart sample, we can drag and drop the node onto another node using the drop event which establish the parent/child relationship in ASP.NET MVC Diagram. Also we need to enable the AllowDrop constraints which shows the highlighter, when we drag the node and mouse hover on the another node. Please refer to the code example below.
Controller
DiagramProperties model = new DiagramProperties();
//define drop event
model.Drop = "drop";
model.DefaultSettings.Node = new Node()
{
//Enable the Allowdrop constraints which shows the highlighter, when we drag the node and mouse hover on the another node. Constraints=NodeConstraints.Default | NodeConstraints.AllowDrop
};
Cshtml
function drop(args) {
var diagram = $("#BusinessChart").ejDiagram("instance");
if (!args.source.cssClass) {
if (diagram.getObjectType(args.target) == "node") {
if (args.element) {
var connector = diagram.findNode(args.element.inEdges[0]);
}
if (connector) {
diagram.updateConnector(connector.name, { sourceNode: args.target.name, targetNode: args.element.name });
}
else {
diagram.add({ name: "connector" + ej.datavisualization.Diagram.Util.randomId(), segments: [{ type: "orthogonal" }], sourceNode: args.target.name, targetNode: args.element.name });
}
}
}
//update the layout
diagram.layout();
}
