Hi Geoffrey & all Support:

User have a further question, at the server side in index.cshtml.cs file.
I only can use this.GetCmp<TextField>("fieldID").setValue("test") , but can not get value from this.GetCmp<TextField>("fieldID").Value, also when I need to get the hidden status from a button , I can not get the current hidden status.
Becuase from my code I need to check the button status and process next code logic.

Could Ext.net Support handle above questions ?
Thank you very much again.
