Why is the boolean variable always resetting to false;
<p>I have a boolean variable declared at the top of a class and when a radio button is selected on a page, the variable gets set to true, but when the page is reloaded, the variable gets reset back to false.  One way I have handled this was by using the static keyword, but I am not sure if this is the best way to handle this.  Here is the class where I tried doing things in the Page_Load event, but it is still resets the variables to false.</p>

<pre><code>public class SendEmail
{
    bool AllSelected;

protected void Page_Load(object sender, EventArgs e)
{
    if(!Page.IsPostBack)
    {
        AllSelected = false;
    }
}

protected void rbAll_SelectedIndexChanged(object sender, EventArgs e)
{
    if(rbAll.SelectedValue == "All")
       AllSelected = true;
}

public Send()
{
   if(AllSelected)
   {
       //Send Email. Never runs because AllSelected is always false;
   }
}

}
</code></pre>
