i want to try to delete data from one xml(gridview) file by using

GridMember_RowDeleting

event and store or save into another xml file.
anyone have an idea about it to save my deleted data from one xml file to another xml file..

What I have tried:

my first xml file code is

protected void GridMember_RowDeleting(object sender, GridViewDeleteEventArgs e)
  {


      showxmlfiledata();


      DataSet ds = GridMember.DataSource as DataSet;


      ds.Tables[0].Rows[GridMember.Rows[e.RowIndex].DataItemIndex].Delete();

      ds.WriteXml(Server.MapPath("~/adsdata.xml"));
      Message.Show("Ad deleted successfully");

      showxmlfiledata();

  }

here showxmlfiledata() code for gridview..

void showxmlfiledata()
   {

       DataSet ds = new DataSet();

       ds.ReadXml(Server.MapPath("~/adsdata.xml"));

       if (ds != null && ds.HasChanges())
       {

           GridMember.DataSource = ds;

           GridMember.DataBind();

       }

       else
       {

           GridMember.DataBind();

       }


   }
