private void advBandedGridView1_CustomUnboundColumnData(object sender,CustomColumnDataEventArgs e)
{
ColumnView columnview = sender as ColumnView;
if (e.Column.FieldName == "SubTotal" && e.IsGetData)
{
e.Value = calcSubTotal
(
Convert.ToSingle(columnview.GetRowCellValue(e.RowHandle,columnview.Columns["Math"])),
Convert.ToSingle(columnview.GetRowCellValue(e.RowHandle,columnview.Columns["Chinese"])),
Convert.ToSingle(columnview.GetRowCellValue(e.RowHandle,columnview.Columns["English"]))
);
}
}
烦请各位高手这段代码的含义!看了很长时间,看不懂!

创建一个ColumnView（行的视图）对象,给这个对象添加三个列Convert.ToSingle(columnview.GetRowCellValue(e.RowHandle,columnview.Columns["English"]))
而且这三个列是Single类型的.Convert.To...是类型转换.

private void 和 private string 有什么区别 private void button16_Click(object sender,EventArgs e) 英语翻译private void button1_Click(object sender,EventArgs e){if private 英语翻译class Company //公司类{private:Person *Worker; //员工表void Cl #include class base { Private:int x,y; public:void setxy(int 1.给出如下代码：class Test{ private int m; public static void fun() typedef void (*funcptr)(void) private a. private equity private affair Private Label
