盡管autopostback設置為true，RadioButtonList仍未發布

Question

我在嘗試使單選按鈕列表選定的索引更改觸發時遇到問題，盡管我在其他任何ASP控件上的回發都沒有問題，但是單選按鈕列表給我帶來了麻煩。 如果你們中的一個人可能會發現問題所在，我將在后面加上我的asp代碼和c＃代碼。

我有8個單選按鈕列表，它們都在自己的更新面板中設置為始終更新，每個單選按鈕列表的autopostback設置為true。

我有邏輯代碼來更改兩個asp：labels，一個基於單選按鈕列表選擇更改平均分數，以及一個根據平均分數的值分配風險級別。

<table class="td-table-bordered" style="width: 90%">

                        <th>
                            <asp:Label ID="CategoryLabel" runat="server" Text="Category"></asp:Label>
                        </th>

現在我的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) {
    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";
    }
}

這應該發回，我絕對不能確定為什么表單上的所有其他控件都發回正常，而不是這些。 有人可以幫助確定原因嗎？ 關於此的堆棧溢出問題沒有其他問題適用於我的問題。

非常感謝。

您的標簽在更新面板之外，這就是為什么它不起作用的原因。 所有單選按鈕都回發，沒有任何問題。

我建議您將所有控件包裝在一個更新面板中。
