我在这里有点困惑，我搞砸了，帮忙。在这行代码中：
dtCurrentTable.Rows [0] [＆＃34; Kolicina＆＃34;] = Convert.ToInt32（Label37.Text）+ Counter1;
在接下来的两个方法中Button6_Click和Button7_Click这个Label37.Text值应该在每次用户按下按钮时增加一个。所以我希望下一个方法中的这个标签值从每个按钮的当前值开始计数一次click.I使用viewState执行此操作，它只适用于其中一个按钮，在secound按钮上不起作用。在我看来它保留了Label37的先前值，但是每次点击btnTest_Click它都会在变量小数中有新值newValue.How如何解决这个问题？
protected void btnTest_Click(object sender, EventArgs e)
{
if (Session["Markici"] != null)
{
var clickedRow = ((Button)sender).NamingContainer as GridViewRow;
var clickedIndex = clickedRow.RowIndex;
decimal old = dtCurrentTable.Rows[clickedIndex].Field<decimal>("Kolicina");
decimal oldIznos = dtCurrentTable.Rows[clickedIndex].Field<decimal>("VkIznos");
decimal VkDanok = dtCurrentTable.Rows[clickedIndex].Field<decimal>("VkDanok");
string Cena1 = dtCurrentTable.Rows[clickedIndex].Field<string>("Cena1");
int TarifaID = dtCurrentTable.Rows[clickedIndex].Field<Int16>("TarifaID");
decimal newValue = old - 1; //
Label37.Text = newValue.ToString();
decimal newIznos = oldIznos - Convert.ToDecimal(Cena1);
dtCurrentTable.Rows[clickedIndex].SetField("Kolicina", newValue.ToString());
dtCurrentTable.Rows[clickedIndex].SetField("VkIznos", newIznos.ToString());
if (old == 0)
{
dtCurrentTable.Rows[clickedIndex].Delete();
dtCurrentTable.AcceptChanges();
}
