Values not updating if set FlyPostBack to true

FlyPostBack prevents the application to do a FullPostBack so the server side event won't get called.

I suggest you to use OnNodeSelect ClientSideEvent to call the desired function from client side. I made an example for you which can be downloaded from the attachment below.

I hope this helps you in a way.

Hi Erwin,

I appriciate your response. I am doing exactly same as you did in sample file. But you didn't use Flypostback settings. My application has more than 2000 nodes so when I select a node to drag drop it takes time and not dragable until it complete node selected index event processing, which makes application lazy and drag and drop is not smooth. Flypostback mode might help application to smooth drag and drop.

I have modified sample and attached it. Its not working, controls are not getting updated values.

Please let me know how Flypostback works.

Regards,

Shailendra Singh

Hello Shailendra,

Have you tried using Session to store the items? I made a simple sample for you regarding your requests. In this sample, you could select a node and display the selected node on a label. It also allows you to enable or disable a textbox and radiobuttons. You can download the sample from the attachment below.

Hope this helps.

Best Regards,

My application needs to do server side processing on treeview selected index change, and displays selected node text and enabled status, on the textbox and radiobuttons.

I made FlyPostBack settings to true(so that drag and drop easy), though FlyPostBack is causing postback but not updating the selected node text and enable on the textbox and radiobuttons.

How to get rid of this problem. Please suggest.
