<a href="http://www.mail-archive.com/wix-users@lists.sourceforge.net/msg05097.html">http://www.mail-archive.com/wix-users@lists.sourceforge.net/msg05097.html</a> gives an solution to republish the properties that were changed in the custom action immediately after it. Here is an example of how I have gotten it to work in my code: <pre class="lang-xml prettyprint-override"><code><?xml version="1.0" encoding="utf-8"?> <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"> <Fragment> <Binary Id="ConnectionStringExtension.dll" SourceFile="$(var.ConnectionStringExtension.TargetDir)$(var.ConnectionStringExtension.TargetName).CA.dll" /> <CustomAction Id="MyCustomAction" BinaryKey="ConnectionStringExtension.dll" DllEntry="VerifyConnectionString" Execute="immediate" /> <UI> <Dialog Id="ConnectionStringDlg" Width="370" Height="270" Title="Database Settings - [ProductName]" NoMinimize="yes"> <Control Id="ConnectionStringLabel" Type="Text" X="45" Y="73" Width="100" Height="15" TabSkip="no" Text="&amp;Connection String:" /> <Control Id="ConnectionStringEdit" Type="Edit" X="45" Y="95" Width="220" Height="15" Property="CONNECTION_STRING" Text="{200}" /> <Control Id="Back" Type="PushButton" X="180" Y="243" Width="56" Height="17" Text="&amp;Back"> </Control> <Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17" Default="yes" Text="&amp;Next"> <Condition Action="enable"><![CDATA[CONNECTION_STRING <> "" AND CONNECTION_STRING_VALID = "1"]]></Condition> <Condition Action="disable"><![CDATA[CONNECTION_STRING = "" OR CONNECTION_STRING_VALID = "0"]]></Condition> </Control> <Control Id="Cancel" Type="PushButton" X="304" Y="243" Width="56" Height="17" Cancel="yes" Text="Cancel"> <Publish Event="SpawnDialog" Value="CancelDlg">1</Publish> </Control> <Control Id="BannerBitmap" Type="Bitmap" X="0" Y="0" Width="370" Height="44" TabSkip="no" Text="WixUI_Bmp_Banner" /> <Control Id="Description" Type="Text" X="25" Y="23" Width="280" Height="15" Transparent="yes" NoPrefix="yes"> <Text>Please enter database configuration</Text> </Control> <Control Id="BottomLine" Type="Line" X="0" Y="234" Width="370" Height="0" /> <Control Id="Title" Type="Text" X="15" Y="6" Width="200" Height="15" Transparent="yes" NoPrefix="yes"> <Text>{\WixUI_Font_Title}Database Settings</Text> </Control> <Control Id="BannerLine" Type="Line" X="0" Y="44" Width="370" Height="0" /> <Control Id="VerifyButton" Type="PushButton" Width="56" Height="16" X="45" Y="118" Text="Verify"> <Publish Event="DoAction" Value="MyCustomAction">1</Publish> <Publish Property="TEMP_VERIFIED" Value="[CONNECTION_STRING_VALID]">1</Publish> <Publish Property="CONNECTION_STRING_VALID" Value="[TEMP_VERIFIED]" /> </Control> </Dialog> </UI> </Fragment> </Wix> </code></pre> The CustomAction sets the value of CONNECTION_STRING_VALID to either 1 or 0 depending if it is valid or not and I have defined elsewhere that by default its value is 0 <pre class="lang-xml prettyprint-override"><code><Property Id="CONNECTION_STRING_VALID" Value="0" /> </code></pre> Now when I click my verify button if the string is valid the next button is enabled

1. COThat worked beautifully. In my opinion a much better solution than the twin dialog approach. I do, however, experience a few seconds delay between when the action is complete, and the button is activated. Definitely not a problem, just a curiosity.

2. COBeen a while since I used it but from memory it was pretty instantaneous for me, maybe something to do with your action?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
