【问题描述】：
我在尝试触发单选按钮列表选择的索引更改时遇到问题，虽然我对任何其他 asp 控件的回发没有问题，但单选按钮列表给我带来了麻烦。我将在其中包含我的 asp 代码和 c# 代码隐藏，以防你们中的任何人能够辨别出问题所在。
我有 8 个单选按钮列表，都在它们自己的更新面板中，设置为始终更新，并且每个单选按钮列表都将 autopostback 设置为 true。
我有更改两个 asp:labels 的逻辑代码，一个根据单选按钮列表选择更改平均分数，另一个根据平均分数的值分配风险级别。

现在是我的 c#
double averageRating, desktopProbabilityRating, desktopImpactRating, productivityProbabilityRating, productivityImpactRating, businessProbabilityRating, businessImpactRating, datacenterProbabilityRating, datacenterImpactRating = 0;
protected void DesktopProbabilityButtonList_SelectedIndexChanged(object sender, EventArgs e) {
desktopProbabilityRating = Convert.ToDouble(DesktopProbabilityButtonList.SelectedValue);
calculateAverage();
}
protected void DesktopImpactButtonList_SelectedIndexChanged(object sender, EventArgs e) {
desktopImpactRating = Convert.ToDouble(DesktopImpactButtonList.SelectedValue);
calculateAverage();
}
protected void ProductivityProbabilityButtonList_SelectedIndexChanged(object sender, EventArgs e) {
productivityProbabilityRating = Convert.ToDouble(ProductivityProbabilityButtonList.SelectedValue);
calculateAverage();
}
protected void ProductivityImpactButtonList_SelectedIndexChanged(object sender, EventArgs e) {
productivityImpactRating = Convert.ToDouble(ProductivityImpactButtonList.SelectedValue);
calculateAverage();
}
protected void BusinessProbabilityButtonList_SelectedIndexChanged(object sender, EventArgs e) {
businessProbabilityRating = Convert.ToDouble(BusinessProbabilityButtonList.SelectedValue);
calculateAverage();
}
protected void BusinessImpactButtonList_SelectedIndexChanged(object sender, EventArgs e) {
businessImpactRating = Convert.ToDouble(BusinessImpactButtonList.SelectedValue);
calculateAverage();
}
protected void DatacenterProbabilityButtonList_SelectedIndexChanged(object sender, EventArgs e) {
datacenterProbabilityRating = Convert.ToDouble(DatacenterProbabilityButtonList.SelectedValue);
calculateAverage();
}
protected void DatacenterImpactList_SelectedIndexChanged(object sender, EventArgs e) {
datacenterImpactRating = Convert.ToDouble(DatacenterImpactButtonList.SelectedValue);
calculateAverage();
}
protected void calculateAverage() {
averageRating = (desktopProbabilityRating + desktopImpactRating + productivityProbabilityRating + productivityImpactRating + businessProbabilityRating + businessImpactRating + datacenterProbabilityRating + datacenterImpactRating) / 8;
OverallRating.Text = averageRating.ToString();
if(averageRating <= 1) {
OverallRisk.Text = "Low";
}
else if(averageRating > 1 && averageRating < 3) {
OverallRisk.Text = "Med";
}
else if(averageRating >=3 || desktopProbabilityRating == 3 || desktopImpactRating == 3 || productivityProbabilityRating == 3 || productivityImpactRating == 3 || businessProbabilityRating == 3 || businessImpactRating == 3 || datacenterProbabilityRating == 3 || datacenterImpactRating == 3) {
OverallRisk.Text = "High";
}
}
这应该发回，我绝对无法确定为什么我的表单上的所有其他控件都可以正常发回而不是这些。有人可以帮助确定原因吗？没有其他关于堆栈溢出的问题适用于我的问题。
非常感谢。
