Web grid syntax error

Question

@{

    var gd = new WebGrid(Model, canPage: true, rowsPerPage: 5, selectionFieldName: "selectedRow",ajaxUpdateContainerId: "gridContent");

        gd.Pager(WebGridPagerModes.NextPrevious);

}

 

this is the code am writing in view for creating a web grid ,but its showing the following error ,

 

The best overloaded method match for 'System.Web.Helpers.WebGrid.WebGrid(System.Collections.Generic.IEnumerable<dynamic>, System.Collections.Generic.IEnumerable<string>, string, int, bool, bool, string, string, string, string, string, string, string)' has some invalid
