DropDownList导致UpdatePanel（Inside Repeater）中的整页回发 [英] DropDownList is causing full page post back in UpdatePanel (Inside Repeater)

问题描述

我有一个名为AddressEdit的用户控件，它在更新面板中包含两个下拉列表框，如下所示：

I have a user control called AddressEdit, that contains two drop down list boxes inside a update panel like this:

<asp:UpdatePanel ID="upCountry" runat="server" >
    <ContentTemplate>
   <tr class="row">
            <td class="item-name">
                <%#GetLocaleResourceString("Account.Country")%>:
            </td>
            <td class="item-value">
                <asp:DropDownList ID="ddlCountry1" AutoPostBack="true" runat="server"  OnSelectedIndexChanged="ddlCountry1_SelectedIndexChanged"

                    Width="137px">
                </asp:DropDownList>
            </td>
        </tr>

        <tr class="row">
            <td class="item-name">
                <%#GetLocaleResourceString("Account.StateProvince")%>:
            </td>
            <td class="item-value">
                <asp:DropDownList ID="ddlStateProvince1" AutoPostBack="False" runat="server" Width="137px">
                </asp:DropDownList>
            </td>
        </tr>
   </ContentTemplate>
</asp:UpdatePanel>

我我在转发器中使用此用户控件。

And I am using this user control in a repeater.

<asp:Repeater ID="rptrBillingAddresses" runat="server">
            <ItemTemplate>
                <div class="address-item">
                    <CtrlAddressDispla:AddressDisplay ID="BillingAddresses" runat="server" Address='<%# Container.DataItem %>'

                        ShowEditButton="true" ShowDeleteButton="true" />
                </div>
            </ItemTemplate>
            <SeparatorTemplate>
                <div class="clear">
                </div>
            </SeparatorTemplate>
        </asp:Repeater>

现在的问题是，每当我在 ddlCountry 中改变国家时，它会导致整页回发而不是部分回发。



如何解决这个问题？

Now problem is that, whenever I change country in ddlCountry its causing full page post back instead of partial postback.

How to resolve this problem?

没有看到代码为您的 ScriptManager 我不能100％确定，但我认为你需要在 ScriptManager 上设置 EnablePartialRendering true：

Without seeing the code for your ScriptManager I can't be 100% sure but I think you need to set EnablePartialRendering on the ScriptManager to true:

add ClientIDMode = AutoID到您的下拉列表或页面属性

add ClientIDMode="AutoID" to your dropdownlist or in page attribute
