尽管 autopostback 设置为 true，但 RadioButtonList 不回发

Question

我在尝试让单选按钮列表选择的索引更改生效时遇到问题，虽然我在任何其他 asp 控件上的回发都没有问题，但单选按钮列表给我带来了麻烦。我将包括我的 asp 代码和 c# 代码隐藏，以防你们中的任何一个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自动回发设置为 true。

我有代码隐藏逻辑更改两个 asp:labels，一个根据单选按钮列表选择更改平均分数，一个根据平均分数的值分配风险级别。

现在我的 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) {

    calculateAverage();
}

protected void BusinessProbabilityButtonList_SelectedIndexChanged(object sender, EventArgs e) {

    calculateAverage();

    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";
    }
}

这应该回发，我绝对不能确定为什么我的表单上的每个其他控件都能正常回发，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。

提前致谢。

Answer 1

您的标签在更新面板之外，这就是它不起作用的原因。所有单选按钮回发都没有任何问题。

我建议您将所有控件都包含在一个更新面板中。
