you can on onrowdatabound event of gridview.

protected void surgicalgridview_rowdatabound(object o, gridviewroweventargs e) {                if (e.row.rowtype == datacontrolrowtype.datarow)     {          e.row.cells[0].width = new unit("200px");          e.row.cells[1].width = new unit("400px");          // , on     }  } 

add gridview markup

<asp:gridview ...............................         onrowdatabound="surgicalgridview_rowdatabound">    // add event , execute above code  </asp:gridview>
