C# Ext.net：显示可见 = "false" 的窗口

当窗口Visible="false"时，我如何显示窗口？

<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 WndwLinkDoc.Show()但它不起作用。

如果我使用Hidden="true"则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>

全窗口代码：

<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">                                                
                        <Items>

                                                                <ext:ModelField Name="id" Type="Int" />

                                                        </ext:Model>

                                        </ext:ComboBox>
                            <ext:Button runat="server" Text="Link doc" >
                            </ext:Button>
                        </Items>
                    </ext:Window>

<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">

并且您可以从代码隐藏中使用;

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

我知道

，你想在代码隐藏的 DirectEvent 期间显示这个窗口，对吧？在这种情况下，您必须在将可见标志设置为 true 之前使用 Render 方法。这是一个工作示例：

*。.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();
    }
}
