. Net databases cannot be updated with updata

At first, I assigned a value to the text box when loading the page. This function is used: BindTextBoxs ();
When you click the update button, ExecuteNonQuery () returns 1 line, but does not update the database.

The logic error is found and should be changed:

If (! IsPostBack)
{
BindTextBoxs ();
}

The reason is: if you do not control whether it is sending a response, when you click the update button, the program will first execute

In the protected void Page_Load (object sender, EventArgs e) content, BindTextBoxs () resets the text box and then performs the update operation. As a result, the update fails.
