我正在使用 DropDownList 从 FormViews 中提取数据并正确计算它。我用Label13看看同学们是什么Run Time is。如果我选择用户一并放置它计算结果的所有数据，然后我选择用户二（还没有数据），现在如果我再次选择用户一而不将任何信息放入用户二，它将从用户复制 Label13 结果给用户二的数据。（如果有意义的话）。具体来说Label13。
这是一些代码：
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
Label13.Text = "";
if (DropDownList1.SelectedValue != "0")
{
Score();
}
}
protected void Score()
{
Label13.Text = "";
//Button1.Visible = true;
Button5.Visible = true;
Label19.Visible = false;
UpdatePanel4.Visible = true;
FormView2.DataBind();
Label sitL = ((Label)FormView2.FindControl("SitUpsLabel"));
Label pushL = ((Label)FormView2.FindControl("pushUpsLabel"));
Label MeterL = ((Label)FormView2.FindControl("MeterLabel"));
if (DropDownList1.SelectedValue != "0")
{
if (sitL.Text != "" || pushL.Text != "" || MeterL.Text != "")
{
int count = 0;
int counter2 = 0;
string test = sitL.Text;
decimal val;
string test2 = pushL.Text;
decimal val2;
string test3 = MeterL.Text;
decimal val3;
Decimal.TryParse(test, out val);
Decimal.TryParse(test2, out val2);
Decimal.TryParse(test3, out val3);
//decimal holder = 0;
//decimal holder2 = 0;
//decimal scores = 0;
for (int i = 0; i < situps.Length; i++)
{
if (val == 30 + count)
{
Label14.Text = "SitUps Score: " + situps[i];
holder = situps[i];
}
count = count + 1;
}
for (int i = 0; i < pushups.Length; i++)
{
if (val2 == 21 + counter2)
{
Label15.Text = "Push Ups Score: " + pushups[i];
holder2 = pushups[i];
}
counter2 = counter2 + 1;
}
decimal counter = 0;

int placer = 0;
for (int i = 0; i < 1700; i++)
{
if (val3 == 56 + counter)
{
Label20.Text = "300 Meter: " + meterRun[placer];
holder3 = meterRun[placer];
}
counter = counter + .01M;
sideCounter = sideCounter + .01M;
