I would like to change the text that is displayed based on criteria - aka "loading treeview node n of x" how would I go about that.

Hi Christopher, 

 

Thanks for contacting Syncfusion support. 

 

We have analyzed your query, and we have provided option to change the text of TreeNode dynamically by using public method “updateText”. You need to pass the Id or object of the node and new text to this method. It will update the text of the given TreeView node. Please refer the below code sample. 

 

[Script] 

 

$("#tree").ejTreeView({ 

    loadOnDemand: true, 

    allowEditing: true, 

    fields: { dataSource: localData, id: "id", parentId: "pid", text: "name", hasChild: "hasChild" }, 

    nodeExpand: function (args) { 

        if (args.value.indexOf("-expanded") == -1) 

            this.updateText(args.currentElement, args.value + "-expanded"); 

    } 

}); 

 

 

For more details about the updateText method then please refer the help document,
