I’m gonna create an Ext.Net’s TreeGrid with custom nodes.
e.g :
All of TreeGrid’s nodes should have a textbox at the front of itself and users should write a number at it.
See the below image :

Custom Ext.Net TreeGrid

Also, I have to get each nodes’ textbox values in code behind at postback.

Could you please guide me, how I can create it with Ext.net and C# ?
Thanks.
