我有一个带有Edit控件的自定义 UI，我想使用在单击按钮时调用的 ac# 自定义操作来更新它。

这是我为向您展示问题而创建的测试 WIX 片段，它包含 UI 和自定义操作声明。

<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
  <Fragment>
    <UI>
      <Dialog Id="TestDlg" Width="370" Height="270">
        <Control Id="TextBox" Type="Edit" X="80" Y="117" Height="17" Width="250"  Property="EDITBOXVALUE" Text="[EDITBOXVALUE]"/>
        <Control Id="Button" Type="PushButton" X="331" Y="117" Height="16" Width="17" Text="Update">
          <Publish Event="DoAction" Value="UpdateEditBox" Order="1">1</Publish>

          <!-- This is a workaround to update property I found here https://legalizeadulthood.wordpress.com/2009/10/23/ui-custom-action-guidelines/ -->
          <Publish Property="EDITBOXVALUE" Value="[EDITBOXVALUE]" Order="2">1</Publish>
        </Control>
      </Dialog>
    </UI>
    <Binary Id="ServerActions" SourceFile="$(var.CustomActions.TargetDir)$(var.CustomActions.TargetName).CA.dll" />
    <CustomAction Id="UpdateEditBox" BinaryKey="ServerActions" DllEntry="UpdateEditBox" Execute="immediate" Return="check" />
  </Fragment>
</Wix>

这是 C# 自定义操作：

[CustomAction]
public static ActionResult UpdateEditBox(Session session)
{
    session ["EDITBOXVALUE"] = "Updated Value";
    return ActionResult.Success;
}

现在这是我遇到的问题，如果我只是单击按钮，编辑框就会更新，但是，如果我先在编辑框中输入一些文本，然后单击按钮，编辑框将不再更新。

我检查了安装日志（通过使用此命令运行安装程序msiexec.exe /i MyInstaller.msi /l*vx Output.txt），这是我发现的：

MSI (c) (FC!24) [17:13:41:225]: PROPERTY CHANGE: Adding EDITBOXVALUE property. Its value is 'Updated Value'.

Action ended 17:13:49: UpdateEditBox. Return value 1.
Action 17:13:52: CancelDlg. Dialog created
Action ended 17:13:53: WelcomeDlg. Return value 2.

根据此日志，该属性似乎已更新，但并未反映在 UI 上。

有谁知道这里发生了什么，我该如何解决？

这是我想出的一个小技巧来克服这个问题，不是很优雅，但它仍然有效。

主要思想是您拥有主对话框的精确副本，并且每当您想要更新 UI 时，当属性更改时，您只需在这两个副本之间切换。从问题中的示例中，它会是这样的：

<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
  <Fragment>
    <UI>
      <Dialog Id="TestDlg" Width="370" Height="270">
        <Control Id="TextBox" Type="Edit" X="80" Y="117" Height="17" Width="250"  Property="EDITBOXVALUE" Text="[EDITBOXVALUE]"/>
        <Control Id="Button" Type="PushButton" X="331" Y="117" Height="16" Width="17" Text="Update">
          <Publish Event="DoAction" Value="UpdateEditBox" Order="1">1</Publish>
        </Control>
      </Dialog>
    </UI>
    <UI>
      <Dialog Id="TestCopyDlg" Width="370" Height="270">
        <Control Id="TextBox" Type="Edit" X="80" Y="117" Height="17" Width="250"  Property="EDITBOXVALUE" Text="[EDITBOXVALUE]"/>
        <Control Id="Button" Type="PushButton" X="331" Y="117" Height="16" Width="17" Text="Update">
          <Publish Event="DoAction" Value="UpdateEditBox" Order="1">1</Publish>
        </Control>
      </Dialog>
    </UI>
    <Binary Id="ServerActions" SourceFile="$(var.CustomActions.TargetDir)$(var.CustomActions.TargetName).CA.dll" />
    <CustomAction Id="UpdateEditBox" BinaryKey="ServerActions" DllEntry="UpdateEditBox" Execute="immediate" Return="check" />
  </Fragment>
</Wix>

请注意，我不再使用<Publish Property="EDITBOXVALUE" Value="[EDITBOXVALUE]" Order="2">1</Publish>它，因为不再需要它，因为我们正在切换到另一个 UI。

然后在您的 UI 序列中的某个位置，您将拥有：

  <Publish Dialog="TestDlg" Control="Button" Event="NewDialog" Value="TestCopyDlg">1</Publish>
  <Publish Dialog="TestCopyDlg" Control="Button" Event="NewDialog" Value="TestDlg">1</Publish>
