If this variable is based on $_GET then you can simply put it in defaultValue property of editoptions.

If it’s coming from $_POST then you need to preserve it in session and then use it.

If it doesn’t solve, share grid code as well.

Hello,

I reviewed the code but I don’t find any variable $datechange in it. Please explain where are you trying to set this variable value. Also tell that from where this variable is populated (get/post?)
