I have an ASP.NET project with a simple webpage.When I load the page the textbox display "Hello". When I click the "btnUpload" the text goes away.
I tried !IsPostBack in the Load\_Form function gut the just make the text stay the same.

```
protected void Page_Load(object sender, EventArgs e)
{   
    TextBox1.Text = "Hello";               
}

protected void btnUpload_Click(object sender, EventArgs e)
{
   TextBox1.Text = "Good Bye";

}

```
