protected void Page_Load( object Sender ,EventArgs e)
{
if (Request.QueryString["viewList"] != null)
{
if (Request.QueryString["viewList"] == "1")
{
mvUser.SetActiveView(viewFile);
DataSet ds = new DataSet();
lblTest.Text = Request.QueryString["viewList"];
FillRepeater();
}
}

}

In ProductLogin

Hey there,

I took a quick glance at your problem. I think DoThis is still firing. However it causes a postback and thus reloads the page each time firing off your load event. Now I'm assuming you're using lblTest as a visual cue. If this is the case the page would appear to be unchanged each time as you set the text for lblTest in the load event.

If this is indeed the cause of your problems the fix would be to use the IsPostback Property of the page to determine if it is the first time the page has been opened or if the user has triggered a postback.

Example:

protected void Page_Load( object Sender ,EventArgs e)
{
     if (!IsPostback)
     {
           //put querystring code here
     }
}
 

Hope this helps!
