C# tabcontroll控件怎么让各个标签独立运行互不影响，像浏览器标签一样

判断tabcontrol选定的标签。selectedindex属性
下面是我写的代码，请参考
private void TbCont_SelectedIndexChanged(object sender, EventArgs e)
{
if (TbCont.SelectedIndex == 1)
{
///加载征订目录批次 dgvZdmlpc
Maticsoft.BLL.zdmlpc zdmlpcbll = new Maticsoft.BLL.zdmlpc();
zdmlpclist = zdmlpcbll.GetAllList();
dgvZdmlpc.DataSource = zdmlpclist.Tables[0];
this.dgvZdmlpc.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
}
}
