You should use as following

<style type="text/css">
    #MainContent_GridView1 {
        border: solid 1px Black !important;
     }
    #MainContent_GridView1 tr {
        border: solid 1px Black !important;
     }
     #MainContent_GridView1 td {
        border: solid 1px Black !important;
     }
 </style>

You need to create class for your tr and td you should also look if you have th is render on your browser if so you need to create class as follow

     #MainContent_GridView1 th {
        border: solid 1px Black !important;
     }
