Why can't my parameters be maintained?

winwing00

xxx.aspx.cs
public class xxx: ...
{
private string Fdw_number;

private void page_load (.............)
{
...
Fdw_number = this.request ["dwid"]
...
}

private void btnOK_ServerClick (object sender, System.Web.UI.ImageClickEventArgs e)
{
...
TextBox1.Text = Fdw_number;
...
Ranch
}

I don't know why the value of Fdw_number cannot always be maintained?

Because each time the server sends an HTML document to the client, the life cycle of a page is completed, and the life cycle of private variables is also completed. Use the Session variable to save it.

Can also be saved with viewstate

Viewstate on the same page is better!
