Question

gridview怎么实现点击每行后面的按钮则改行某字段的值减一

Answer 1

//给GridView中的按钮添加上次事件：
public void btTest1_Click(object sender, EventArgs e)
{
Button bt = (Button)sender;
GridViewRow tbr = (GridViewRow)bt.Parent.Parent;
int rowIndex = tbr.RowIndex;
//rowIndex是按钮所在的行号，假如你要把第rowIndex行第一列的值-1，过程如下：
int value = Int32.Parse(GridView1.Rows[rowIndex].Cells[0].Text.Trim());
int newValue = value - 1;
string stRresult = newValue.ToString();
GridView1.Rows[rowIndex].Cells[0].Text = stRresult;

}

Answer 2

获取数据当前行，然后转化成自定义data table,然后foreach每个栏位，最后遇到自己定义的栏位进行减一动作
