Dependent Dropdowns - updating records

I have a PDF table which stores information from a PDF category and a PDF sub category table in main PDF table. I cannot find a tutorial on how to update a record using dynamic dropdowns. I went through the PDF that is on your web site, but found it to be incomplete. Where can I go for help? At one point, was there a movie that showed how to do exactly what I'm describing? Using the dependent dropdowns in update mode?

the key to using dynamic dropdowns on an update page is to add the Populate List from array behavior to the Onload event of the body tag.

you will also need to add the set selected in list behavior to select the correct value based on the recordset.

For each dynamic dropdown on the page, you will need to add the Populate list from array and set selected behaviors to the body's onload event.

Jason, can you post a link to an example of this - on update, please? Thanks!

Sorry, we do not have an example of this being used on update.
You will only need to add the Populate list from array and set Selected in List behaviors to the OnLoad action of the body tag.

Jason, on my update page, that option (WA Dynamic Dropdowns > Populate List From Array) is grayed out. I cannot apply it to the <body> tag.

Have you added the Create Dynamic Array behavior to the page?

Can you send a copy of the page so I can take a look at the code.

Jason, I'm attaching the actual page that I'm working with. I'm not sure what I've missed seeing that the documentation doesn't exist for the update mode. Thank you!

In design view, click the pdfCatID select list, then clic kthe dynamic button in the property inspector, In the Select value Equal to section, click the lightning bolt and select the pdfID column from the WADApdfarticles recordset.

On you body tag, you have the Poiulate list from array behavior set correctly, but you dhave set the Set Selected In List behavior to use the pdfCatID list instead of the pdfSubCatID list, edit that so it is using the child list.

The first list box is working now, but the 2nd is not.

<body onload="WA_FilterAndPopulateSubList(Recordset2_WAJA,MM_findObj('pdfCatID'),MM_findObj('pdfSubCatID'),0,0,false,': ');WA_setSelectionsInChildList(MM_findObj('pdfSubCatID'),<?php echo $row_WADApdfarticles['pdfSubCatID']; ?>)">

My 2nd listbox includes the following:

<select id="pdfSubCatID" name="pdfSubCatID" onchange="pdfCatID_reload(this)">
<?php
do {
?><option value="<?php echo $row_Recordset2['pdfSubCatID']?>"><?php echo $row_Recordset2['pdfSubCatName']?></option>
<?php
} while ($row_Recordset2 = mysql_fetch_assoc($Recordset2));
$rows = mysql_num_rows($Recordset2);
if($rows > 0) {
mysql_data_seek($Recordset2, 0);
$row_Recordset2 = mysql_fetch_assoc($Recordset2);
}
?>
</select>

Thanks!

the onchange event may be causing the issue:
<select id="pdfSubCatID" name="pdfSubCatID" onchange="pdfCatID_reload(this)">

change that to:
<select id="pdfSubCatID" name="pdfSubCatID">

If your still having issues, I'll need to see it in the browser, let me know and I'll start a private ticket.
