Answer 1

Do you want this like?

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    e.Row.Cells[index].Visible = false;
}

确保已将column的Datasource属性指定为数据库列名

Answer 3

Add OnRowDataBound of your GridView

<asp:GridView ID="GridViewID" runat="server" OnRowDataBound="gvTest_RowDataBound" >

in RowDataBound

First, check the roles of user and then you can check the condition and hide your column

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
 {
  //check User Type
   int userType = //Your User Type Here;
   if (userType == 1)
    {
      GridViewID.Columns[15].Visible = false;
    }
   else if (userType == 2 || userType == 3)
    {
     GridViewID.Columns[5].Visible = false;
     GridViewID.Columns[6].Visible = false;
    }                                                                                                                                     
  }
