Question

如果窗口有Visible="false"，我该如何显示？

<ext:Window ID="WndwLinkDoc" runat="server"
                        Width="650" Height="350" CloseAction="Hide"                      
                        X="120" Y="120" Visible="false" Title="Link doc"
                        ConstrainHeader="true"
                        Layout="FitLayout">

我试过了 WndwLinkDoc.Show() 但它不起作用。

如果我使用Hidden="true"，我在访问此内容时遇到问题：

<ext:Hidden runat="server" ID="hdnclid" />

通过将其值传递给参数：

来存储在窗口中

<ExtraParams>
     <ext:Parameter Name="clientid" Value="#{hdnclid}.value" Mode="Raw"/> //error hdnclid undefined
</ExtraParams>

完整的窗口代码：

<ext:Hidden runat="server" ID="hdnclid" />
<ext:Window ID="WndwLinkDoc" runat="server"
                        Width="650" Height="350" CloseAction="Hide"                      
                        X="120" Y="120" Visible="false" Title="Link doc"
                        ConstrainHeader="true"
                        Layout="FitLayout">

Answer 1

<ext:Window ID="WndwLinkDoc" runat="server"
                        Width="650" Height="350" CloseAction="Hide"                      
                        X="120" Y="120" **Hidden="true"** Title="Link doc"
                        ConstrainHeader="true"
                        Layout="FitLayout">

你可以使用代码隐藏;

WndwLinkDoc.Hide();
WndwLinkDoc.Show();

Answer 2

据我所知，你想在Code Behind的DirectEvent中显示这个窗口，对吧？在这种情况下，在将Visible标志设置为true之前，必须使用Render方法。这是一个有效的例子：

*。ASPX

<ext:ResourceManager runat="server" />
<ext:Window runat="server" ID="myWindow" Visible="false" Title="Window Test"  />
<ext:Button runat="server" Text="Show Window">
    <DirectEvents>
        <Click OnEvent="Button_Click" />
    </DirectEvents>
</ext:Button>

*。aspx.cs

protected void Button_Click(object sender, DirectEventArgs e)
{
    if (!myWindow.Visible)
    {
        myWindow.Visible = true;
        myWindow.Render();
    }
}

C＃Ext.net：使用Visible显示窗口=＆＃34; false＆＃34;
