ResolveURL and Master Pages


  • Hi all,

    I am having issues with importing CSS files within my master page. The issue is ResolveURL does not work properly in returning paths in some cases.

    For example, this code works fine in some master pages and does not work properly in other master pages:

    <link href="<%# ResolveUrl("App_Themes/Standard/Default.css") %>" rel="stylesheet" type="text/css" />



    If the above is replaced with

    <link href="<%= ResolveUrl("App_Themes/Standard/Default.css") %>" rel="stylesheet" type="text/css" />

    then it works fine only in some master pages

    Has anyone encountered such issues in importing CSS and JS files using ResolveURL? Is there a standard way to import these files from master pages?

  • ResolveURL will return the path "relative" to the "masterpage".

    you can utilize BaseURL as a workaround for your problem, please refer:

    Hope this helps...

  • Hi YJShah,


    Welcome to MSDN forum!

    Here is a link shows how to import master page.

    I often drag the .css files in the solution files to .aspx pages. It will automatically generate the code like:

    <link href="Library/CSS/MasterPageStyle.css" rel="stylesheet" type="text/css" />



    Hope these helps, if you have any problems, please feel free to let me know.


    Best Regards,

    add this code to Page_Load of MasterPage

            Page.Header.DataBind();//resolve the script binding error

    this code rebind the header after page load and ResolveUrl Work fine ;)

    you can win, if you want.
