Question

这是我发布的有点重复的问题 Stop DropDownList SelectedIndexChanged Event firing on FormView command。现在我遇到了这些不同的问题。

在这里，我从Listbox（我更愿意拥有）更改为editItemTemplate中的Combobox。当我第一次选择一个项目（百分比）时，Combobox onSelectedIndexChanged事件会像我想要的那样触发。但是当我去选择原始物品（吨）时它不会发射。我正在尝试重新创建一个切换。

我切换到组合框以使用SelectionChangeCommitted事件。但是，它并没有出现在我的智能感知中。我尝试手动输入它，当然它根本不起作用。

我的目标是让用户输入值作为实际吨数的总数或实际值的百分比，然后来回切换。将插入数据库的最终值将以吨为单位。

我想要： a）使用列表框并修复在提交表单时不会触发“onSelectedIndexChanged”事件的问题 b）使这个组合框正确点火。我猜它不会，除非我可以让SelectionChangeCommitted事件显示出来 c）一种我不知道的更好的解决方法。

的.aspx：

<asp:Panel ID="pnlRecycledMaterialsReceivedForm" runat="server" Visible="false">
    <asp:FormView ID="fvAddRecycledMaterialsReceived" runat="server" SkinID="annualReportFormview" EnableViewState="false"
        HeaderText="Selected Recycled Materials Received Detail" DataKeyNames="RecycleDetailId" DefaultMode="Insert"
        DataSourceID="odsRecycledMaterialsReceivedDetail" OnDataBound="fvAddRecycledMaterialsReceived_DataBound" 
        OnItemCommand="fvAddRecycledMaterialsReceived_ItemCommand" OnItemInserted="fvAddRecycledMaterialsReceived_ItemInserted"
        OnItemUpdated="fvAddRecycledMaterialsReceived_ItemUpdated" OnItemDeleted="fvAddRecycledMaterialsReceived_ItemDeleted">
        <EditItemTemplate>
            <asp:TextBox ID="tbxRecycledTotalWasteQuantity" runat="server" Text='<%# Bind("TotalWasteQuantity") %>' Width="64px"></asp:TextBox>
            <asp:TextBox ID="tbxRecycledWasteCommercialQuantity" runat="server" Text='<%# Bind("CommercialQuantity") %>' Width="64px"></asp:TextBox>
            <asp:TextBox ID="tbxRecycledWasteResidentialQuantity" runat="server" Text='<%# Bind("ResidentialQuantity") %>' Width="64px"></asp:TextBox>
            <asp:ComboBox  ID="cmb_Units" runat="server" AutoPostBack="true" EnableViewState="true" OnSelectedIndexChanged="cmb_Units_SelectedIndexChanged">
                <asp:ListItem Text="Tons" Value="1" Selected />
                <asp:ListItem Text="Percent" Value="9" />
            </asp:ComboBox>
            <asp:LinkButton ID="lbtnWasteReceivedUpdate" runat="server" Text="Update" CommandName="Update"
                ValidationGroup="RecycledWasteReceivedDetail" Font-Bold="True" />&nbsp;
            <asp:LinkButton ID="lbtnWasteReceivedInsertCancel" runat="server" Text="Cancel" CausesValidation="False" CommandName="Cancel" />
        </EditItemTemplate>
    </asp:FormView>
</asp:Panel>

的.cs：

protected void cmb_Units_SelectedIndexChanged(object sender, EventArgs e)
{
    TextBox tbxRecycledTotalWasteQuantity = (TextBox)fvAddRecycledMaterialsReceived.FindControl("tbxRecycledTotalWasteQuantity");
    TextBox tbxRecycledWasteResidentialQuantity = (TextBox)fvAddRecycledMaterialsReceived.FindControl("tbxRecycledWasteResidentialQuantity");
    var d_TotalWasteQuantity = Convert.ToDecimal(tbxRecycledTotalWasteQuantity.Text);
    ResidentialQuantity = Convert.ToDecimal(tbxRecycledWasteResidentialQuantity.Text);

    AjaxControlToolkit.ComboBox cmb_units = (AjaxControlToolkit.ComboBox)fvAddRecycledMaterialsReceived.FindControl("cmb_units");

    if (cmb_units.SelectedIndex.ToString() == "1")
    {
        //2 = percent
        //Take tb value and convert to percent
        //300/700 * 100
        tbxRecycledWasteResidentialQuantity.Text = ((ResidentialQuantity / d_TotalWasteQuantity) * 100).ToString();
        //ResidentialQuantity = ResidentialQuantity * (d_TotalWasteQuantity / 100);
    }
    else
    {
        //Else 'tons' was chosen. Convert value(%) to tons. 
        //700 * (43/100) = 301
        ResidentialQuantity = d_TotalWasteQuantity * (ResidentialQuantity / 100);
        tbxRecycledWasteResidentialQuantity.Text = ResidentialQuantity.ToString();
        //tbxRecycledWasteResidentialQuantity.Text = "Tons";
    }
}

Combobox不会在更改时触发事件
