   <script type="text/javascript">
        function MyFunc(){
};
</script>


 ScriptManager.RegisterStartupScript(this, Page.GetType(), "key", "MyFunc()", true);

Semicolon is not required after MyFunc() Call. You can refer this link

Have your script line is should be 

<script type='text/javascript' language="javascript">
//ApplyCSS();
</script>

and please check your function is does not threw any error.

and try with this 

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "Script", "javascript:ApplyCSS();", true);

The likely cause of this error is that ApplyCSS(); isn't defined at the time when the function is called.

So, is the ApplyCSS(); function defined in a .js file? If so, you have to go with this kind of approach:

$(document).ready(function () { ApplyCSS(); } );

You'll need jQuery to do this
