How can I delete the row of treetable by the button press

[former_member555537]

Hi,

My requirement is to delete the treetable row while clicking cancel button..This is my press function code.

	onDelete:function(evt)
		{
			var sPath = evt.getSource().getBindingContext().getPath();
		
		  
		    var oObj = this.getView().getModel().getObject(sPath);
		    console.log();
		    sPath.remove();
		    this.getView().getModel().refresh();
		}

Here I am getting error like remove of undefined.

Can anyone help ?

Thanks,

Rahul

Hi Rahul,

sPath is a String, so sPath.remove() will fail anyway,

moreover, if the Model has a name, you should call .getBindingContext('modelname').getPath()

Again same error is coming....

onDelete:function(evt)
		{
			var sPath = evt.getSource().getBindingContext("demoModel").getPath();
		    var oObj = this.getView().getModel("demoModel").getObject(sPath);
		    oObj.remove();
		    this.getView().getModel("demoModel").refresh();
		}

place a breakpoint after yougot sObj and oberve it. sObj will bei some sort of JSON Object.

if you want to remove the element from the model, use ...getModel("demoModel").remove(sPAth)

see more in documentation: https://sapui5.hana.ondemand.com/#/api/sap.ui.model.odata.v2.ODataModel/methods/remove

if you need to submit the changes to the backend, you will also need something like ...getModel("demoMOdel").submitChanges()
