Changing / Updating Source – Flicker

[cccMember]

Is there a way to change / update the source of a tree on a timer and prevent the tree from flickering?

Currently I’m doing it by changing the source, I have not found a way to just send an update in yet

	        // Set up the timer
	        var timer = $.timer(function()
	        {
	            //alert('This message was sent by a timer.');
	            // Get Prepared Data
	            var source = getJQXTreeData();
	            //  Create Data Adapter
	            var dataAdapter = new $.jqx.dataAdapter(source);
	            //  Perform Data Binding
	            dataAdapter.dataBind();
	            //  Get the Tree Items
	            var records = dataAdapter.getRecordsHierarchy('id', 'parentid', 'items');
	            // Update Tree
	            $("#jqxTree").jqxTree({ source: records });
	        });
	        timer.set({ time : 5000, autostart : true });

Hi ccc,

By changing the Tree’s Data Source, you actually recreate the Tree and fill it with new hierarchy of items, so there could be a slight delay that result in flickering, if you do it on a timer. We cannot help you to improve that because there will be always some delay during the Tree’s initialization.
