Pre Render Master Pages and ViewState

Question

There is some viewstate stuff going on in the codebehind and then there is an update panel. When I add this into a child page referenced by a master page it breaks all the previously working functionality I had before from my user controls.

child to master page code behind

protected void Page_Load(object sender, EventArgs e)
{
    try
    {
        if (!IsPostBack)
        {
            GetBrands();
            GetStyles();
            GetColors();
            this.BindItemsList();
        }
    }
    catch (Exception)
    { }
}

Try removing the UpdatePannel. If this fixes your code, you will have isolated the issue to your implementation around ViewState. Issues with UpdatePannels and ViewState are not uncommon.
