Question

所以我得到了一个非常简单的标记，其中包含工具栏中的按钮。

现在的问题是，即使按钮“正确”写入DOM，它也不会显示出来有关详细信息，请参阅此屏幕截图：

有人会介意解释为什么设置固定的高度/宽度/位置不会将按钮放在前面而且包含的标记元素都有width=0px;或height=0px;吗？

以下是一个示例：

<body>
<ext:ResourceManager ID="RM" runat="server" />
<ext:Viewport Layout="BorderLayout" runat="server" ID="InnerView" OverflowY="Scroll">
    <Content>
        <ext:Button ID="adminswap" runat="server" Text="Admin-Ansicht umschalten" Hidden="false"
            AllowDepress="true" MinHeight="16" ToFrontOnShow="true" Visible="true" Icon="ArrowSwitchBluegreen">
            <%-- This Guy doesn't show up--%>
        </ext:Button>
        <ext:Panel runat="server" ID="order" Border="false" OverflowY="Scroll">
            <LayoutConfig> 
                <ext:TableLayoutConfig Columns="3" />
            </LayoutConfig>
            <Items>
                <ext:Panel runat="server" Layout="ColumnLayout" RowSpan="2" Border="false">
                    <Content>
                       <p> And here is some Grid-panel, which is of no further interest</p>
                    </Content>
                </ext:Panel>
                <ext:Panel ColSpan="2" runat="server" ID="Panel_Instructions" Title="Türöffnung per Telefon"

                            this also is of no further interest and just for the sake of the sample<br><br> lorem Ipsum dolor sit amet and stuff...

BorderLayout适用于地区。您没有指定任何区域。要使Button可见，您只需删除Viewport的Layout =“BorderLayout”。

这是an example of using a BorderLayout。

ext：即使render = true，按钮也不显示
