如何取出datagrid中的记录
在WebForm 中鼠标单击DtatGrid中的一条记录，如何把它取出来？最好能有个小例子参考一下～谢谢！！～～

[解决办法]
用e.Item.ItemIndex参数
[解决办法]
用SelectedIndexChanged事件
private void DataGrid1_SelectedIndexChanged(object sender, System.EventArgs e)
{
Label0.Text=this.DataGrid1.SelectedItem.Cells[0].Text;
Label1.Text=this.DataGrid1.SelectedItem.Cells[1].Text;
...........
}
