For adding Paging in asp.net gridview you have to handle OnPageIndexChanging event:

Markup:

<asp:GridView ID="gvInvoiceList" 
              DataSourceID="DSInvoiceMaster" 
              AutoGenerateColumns="false"
              CssClass="table table-striped table-hover" 
              EnableSortingAndPagingCallbacks ="false" 
              AllowPaging="True" 
              AllowSorting="True" 
              PageSize="5"
              OnRowCommand="gvPrograms_RowCommand"
              OnPageIndexChanging="gvInvoiceList_PageIndexChanging"  
              runat="server">

Code behind:

protected void gvInvoiceList_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        gvInvoiceList.PageIndex = e.NewPageIndex;
        gvInvoiceList.DataBind();
    }

MSDN example on GridView.OnPageIndexChanging Event.

For Sorting you have track OnSorting event of gridview.

MSDN example reference on GridView.Sorting event.
Here is example reference.

UPDATE: you have not specified datasourceid of gridview here. See updated markup.
