尽管autopostback设置为true，RadioButtonList仍未发布

Question

I'm having issues trying to get radio button list selected index changes to fire, and although I have no issues with postbacks on any other asp control, radio button lists are giving me trouble. I'll include my asp code and c# codebehind in the event one of you may be able to discern what's wrong.

I have 8 radio button lists, all within their own update panels that are set to always update, and each radio button list has autopostback set to true.

I have code behind logic changing two asp:labels, one changing the average scores based on the radiobuttonlist selections, and one assigning a risk level depending on the value of the average score.

<table class="td-table-bordered" style="width: 90%">
                    <tr>
                        <th>
                            <asp:Label ID="CategoryLabel" runat="server" Text="Category"></asp:Label>
                        </th>
                        <th>
                            <asp:Label ID="OccurrenceProbabilityLabel" runat="server" Text="Probability of Occurrence"></asp:Label>
                        </th>

And now my 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();

    calculateAverage();

    calculateAverage();
}

protected void BusinessProbabilityButtonList_SelectedIndexChanged(object sender, EventArgs e) {

    calculateAverage();

    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";
    }
}

This SHOULD be posting back, I absolutely can't determine why every other control on my form posts back just fine and not these. Would someone be able to help determine why? No other question on stack overflow concerning this applied to my problem.

Thanks so much in advance.

Answer 1

Your labels are outside the update panels, that is why it is not working. All the radio buttons postback without any issue.

I would suggest you to wrap all the controls inside one update panel.
