OK. Going nuts here. I've double and triple checked my code to no avail. Still cannot get it to work. A second set of eyes would be helpful. I've deleted cookies and tried all browsers. No luck. Nothing happens. Page simply posts to itself again.

Help??? Thanks!


Web Config:
<pages theme="Monochrome"></pages>




BasePage.cs:

private void Page_PreInit(object sender, EventArgs e)
{
HttpCookie preferredTheme = Request.Cookies.Get("UserPreferredTheme");

if (preferredTheme != null)
{ Page.Theme = preferredTheme.Value; }
}



public BasePage()
{
this.PreRender += new EventHandler(Page_PreRender);
this.PreInit += new EventHandler(Page_PreInit);
}




FrontEnd.master:
<div id="SideBar">Select a Theme<br />
<asp:DropDownList ID="ThemeList" runat="server" AutoPostBack="True"
onselectedindexchanged="ThemeList_SelectedIndexCha nged">
<asp:ListItem>Monochrome</asp:ListItem>
<asp:ListItem>DarkGrey</asp:ListItem>
</asp:DropDownList>
</div>






FrontEnd.master.cs:

protected void Page_Load(object sender, EventArgs e)
{

if (!Page.IsPostBack)
{

string selectedTheme = Page.Theme;
HttpCookie preferredTheme = Request.Cookies.Get("UserPreferredTheme");

if (preferredTheme != null)
{ selectedTheme = preferredTheme.Value;}

if (!string.IsNullOrEmpty(selectedTheme) && ThemeList.Items.FindByValue(selectedTheme) != null)
{ ThemeList.Items.FindByValue(selectedTheme).Selecte d = true; }

}


}



protected void ThemeList_SelectedIndexChanged(object sender, EventArgs e)
{
HttpCookie preferredTheme = new HttpCookie("UserPreferredTheme");
preferredTheme.Expires = DateTime.Now.AddMonths(3);
preferredTheme.Value = ThemeList.SelectedValue;
Response.Cookies.Add(preferredTheme);
Response.Redirect(Request.Url.ToString());
}

Hi there,

Is the page you're testing this on inheriting BasePage? If not, the theme will never be applied.

If you post code here, can you please paste it in Notepad first and then use the Code (#) button on the toolbar to mark your code as code? That makes it easier to read.

Cheers,

Imar

I've been bitten by these matters, you check the code to the displayed code and it matches, In the end I copied the page from the downloaded source code and it worked.. I'll never know where I went wrong but I tend to re-do an example on my own demo websites to ensure I didn't do anything wrong!.

I think there's some tiny bugs within the VWD 2010, sometimes you just have to go back and press space on the code to get Intellisense to guide you in the right direction. (Ive recently upgraded to 2013 and ive finally managed to get the code to load up again!.

>> I think there's some tiny bugs within the VWD 2010

I am sure there are ;-) Be sure to report them on Microsoft's Connect site so they can be fixed, in 2013 or in later releases.

Cheers,

Imar
