How to Update Node and Treeview Content at Runtime in Vue Diagram?

The TreeView component is a graphical control that displays a hierarchical structure of nodes. Syncfusion® provides support for TreeView in Vue Diagram.
To update nodes and TreeView content at runtime, we can use the Dialog component to update both nodes and TreeView nodes.

Define the Dialog component in the HTML.

<ejs-dialog
         id="dialog"
         ref="dialog"
         :visible="false"
         :width="200"
         :height="200"
         :beforeOpen="resetInputValue"
         :footerTemplate="'footerTemplate'"
         :showCloseIcon="true"
       >
         <template v-slot:footerTemplate>
           <div>
             <input
               v-model="inputValue"
               class="e-input"
               aria-label="Message"
               type="text"
               placeholder="Enter your node name here!"
             />
             <button
               @click="send"
               class="e-control e-btn e-primary"
               data-ripple="true"
             >
               Update
             </button>
             <button
               @click="cancel"
               class="e-control e-btn e-primary"
               data-ripple="true"
             >
               Cancel
             </button>
           </div>
         </template>
       </ejs-dialog> 

How to update the content of a node and TreeView.

1. The dialog box will be triggered upon double-clicking the diagram nodes.
2. Edit the input area of the dialog box, and by using the Update button, we can update both the nodes and TreeView content.

send() {
     let content = this.inputValue;
     diagramInstance.selectedItems.nodes[0].annotations[0].content = content;
     let data = workingData;
     let treeview = treeObj;
     let elementNodeId = diagramInstance.selectedItems.nodes[0].id;
     let tempData = data.filter((a) => a.Id === elementNodeId);
     treeview.updateNode(tempData[0].Id, content);
     diagramInstance.dataBind();
     Dialog.visible = false;
  },
