Hello Mohamed,

In order to persists fields values into the RadGrid after postback (when the RadButton is clicked second time and the source fields are empty) you need to change the data source to which the RadGrid is bound when the button is clicked for the first time.
I am sending you a simple example which demonstrates this, please check it out and let me know if it helps you.

Looking forward for your reply.
