ASP专注于输入跳跃错误 [英] Asp Focus on input jumping bug

问题描述

我有一个使用asp.net的Web表单.在这种形式下，我有很多投入.对于每当您按下下拉菜单之一时，焦点就会跳到下一个文本框.

I've got a web form using asp.net. In this form I have a lot of inputs. For one of the drop downs whenever you press it, the focus jumps to the next text box.

这在更新面板中，因为需要进行过滤，隐藏等操作，这需要服务器端的一些工作.

This is in a update panel, because there is some server side work required for filtering, hiding, etc.

如果用户从 visaType_filter 中选择澳大利亚，则它将隐藏 visaType_dd 并显示 visaType_tb .如果他们选择NZ，反之亦然.

If the User chooses Australia from visaType_filter then it hides visaType_dd and shows visaType_tb. If they choose NZ its the other way around.

现在我的问题:

当您单击鼠标以转到下一个输入(或控件)时，是否有错误或使焦点从下拉菜单中跳出的东西?

Is there a bug or something that makes focus jump off of a drop down when you click on it to go to the next input (or control)?

代码:

<fieldset>
    <asp:UpdatePanel ID="visaTypeUpdatePanel" runat="server">
        <ContentTemplate>
            <label>Visa Type Number</label>
            <label>
                <asp:DropDownList ID="visaType_filter" runat="server" Width="40%" OnSelectedIndexChanged="visaType_filter_SelectedIndexChanged" AutoPostBack="true"/>
                <asp:TextBox ID="visaType_tb" runat="server" Width="40%" OnTextChanged="visaType_tb_blur" AutoPostBack="true"/>
                <asp:DropDownList ID="visaType_dd" runat="server" Width="40%"/>
                <asp:Literal ID="visaType_literal" runat="server" />
            </label>
        </ContentTemplate>
    </asp:UpdatePanel>
</fieldset>
<fieldset>
