For the List View Web Part, you are correct: the radio buttons are what they
are.
However, if you change to using a Data View Web Part using FrontPage 2003,
then you have the ability to use any view style and fire connections. One
of the view styles is a dropdown list, so you could do it pretty easily.
There is a bit of trick with using the dropdown style, though, because the
connections wizard does not know how to create an onchange event.
If you want to pursue that, here are the steps:
1. Insert two Data Views of your data.
2. Select one of the Data Views, choose Style from the Data View Details
taskpane.
3. Choose the drop-down box style from the list of styles, click OK.
4. Right click this Data View, choose Web Part connections.
5. Connect to the other Data View as you would normally.
6. Go into Code View.
7. Look for the <a target="_self"> code that looks similar to this (usually,
it would be the first <a> tag in the page) and copy the entire block for the
first XSL:ATTRIBUTE (see below):
<a target="_self">
<!-- NOTE: start copying here -->
<xsl:attribute xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
name="href"><xsl:variable name="cursel">dvt_curselkey={<xsl:value-of
select="$CurrentRowKey"/>}</xsl:variable><xsl:variable
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
name="fields">@ID=<xsl:value-of
select="ddwrt:ConnEncode(string(@ID))"/></xsl:variable>javascript:<xsl:value
-of
select="ddwrt:GenFireConnection(concat('99d2bb39-f973-482c-a0ca-e49b56eae72d
*',$fields),string($cursel))"></xsl:value-of></xsl:attribute>
<!-- NOTE: end copying here-->
<xsl:attribute name="style"><xsl:if test="$CurrentRowKey =
$dvt_curselkey">font-weight: bold;</xsl:if></xsl:attribute>
<xsl:value-of select="@Title"/>
</a>
8. Look for the code for the <option> tag. It should be right above the <a>
tag.
9. Paste in the section of code you copied above.
10. Change the name="href" part to name="value". At this point, you should
have something like this:
<option style="display:{$GroupStyle}">
<xsl:attribute xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
name="value"><xsl:variable name="cursel">dvt_curselkey={<xsl:value-of
select="$CurrentRowKey"/>}</xsl:variable><xsl:variable
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
name="fields">@ID=<xsl:value-of
select="ddwrt:ConnEncode(string(@ID))"/></xsl:variable>javascript:<xsl:value
-of
select="ddwrt:GenFireConnection(concat('99d2bb39-f973-482c-a0ca-e49b56eae72d
*',$fields),string($cursel))"></xsl:value-of></xsl:attribute>
<a target="_self">
<xsl:attribute xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
name="href"><xsl:variable name="cursel">dvt_curselkey={<xsl:value-of
select="$CurrentRowKey"/>}</xsl:variable><xsl:variable
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
name="fields">@ID=<xsl:value-of
select="ddwrt:ConnEncode(string(@ID))"/></xsl:variable>javascript:<xsl:value
-of
select="ddwrt:GenFireConnection(concat('99d2bb39-f973-482c-a0ca-e49b56eae72d
*',$fields),string($cursel))"></xsl:value-of></xsl:attribute>
<xsl:attribute name="style"><xsl:if test="$CurrentRowKey =
$dvt_curselkey">font-weight: bold;</xsl:if></xsl:attribute>
<xsl:value-of select="@Title"/>
</a>
</option>
11. Look for the <select> tag for the drop down. It should look something
like:
<select name="ID" size="1">
12. Add an onchange event handler for the tag, as follows:
<select name="ID" size="1" onchange="eval(this.options.value)">
Now when you change the value your drop-down, your connection should fire.
