Web script storage issues

从今天起流氓

I have a form on my web page that is generated from a database. Then I enter a value in the Text box in the form. Click save. I want to save the form in the database again, but every time I save the form. The content of the text I added is missing.
Excuse me, masters, how to deal with it? Thank you!

Put the method of fetching data into Ispostback

Add before the value
if (! this.IsPostBack)
{
 // Get the value from the database. display.
}
