I have change from protected to public static method for LoadControl method. Im getting this error for the first parameter which is the location of the Webuser control .ascx file.

Error 76 An object reference is required for the non-static field, method, or property 'System.Web.UI.TemplateControl.LoadControl(string)'

The 1st parameter you're giving to LoadControl is a Type and it's value controlName.GetType().BaseType is equal to System.Object (controlName is a string and basetype of string is object) -> error Type 'System.Object' does not inherit from 'System.Web.UI.Control' because LoadControl expects a System.Web.UI.Control type.

You want to instanciate a control giving it's name & some parameters. Unfortunatly, there is no version of LoadControl that accepts those parameters. Fortunatly, it's quite simple to achieve that. Take a look at this article: A Good Example of Asp.net LoadControl with multiple parameters.
