Hi everybody, someone know something for build Dependant ListBoxes for ASP.
The Dependant ListBoxes Action V3 only run in PHP, to the run for build ASP say me.
Warning:XSL definition of the Action was not found in the Action's XML file.
Thank's for all.

There is no such action in CodeCharge Studio. Possibly someone created it for PHP.

I am also looking for the same solution for ASP, so far no luck!
Sixto's solution for PHP is very nice, I wish we could have had a similar solution for ASP too.

To do this, you need 3 javascript functions and some Ajax to populate.
The first function will clear the dependant select box.
The second function will populate a single item into the select box.
The third is a wrapper which calls the clear function and then calls some
ajax code which will dynamically populate the dependant box.
The 3 functions will look something like:
function getActions(sCode){
if (sCode == 0 || sCode == ''){
clearcombo(document.tblTasks.TaskAction);
addopt1(0, 'Select a Task Type to view Actions');
} else {
// a non-empty area
clearcombo(document.tblTasks.TaskAction);
addopt1('', 'Select Value');
AjaxCall("ajaxprovider.asp?action=fetchtaskaction&TaskType=" +
sCode);
}
}
function addopt1(nValue, sText){
// this routine adds a new item to our listbox
document.tblTasks.TaskAction.options[document.tblTasks.TaskAction.length]
= new Option(sText, nValue);
}
function clearcombo(el){
// this routine clears out a listbox or combo box
for (var i = el.options.length; i >= 0; i--){
el.options = null;
}
el.selectedIndex = -1;
}
You trigger this via the onChange event for the parent listbox.
<select name="{TaskType_Name}" class="Select"
onchange="javascript:getActions(document.{HTMLFormName}.{TaskType_Name}.options[document.{HTMLFormName}.{TaskType_Name}.selectedIndex].value)">
<option value="" selected>Select Value</option>
{TaskType_Options}
</select>
I am using the Ajax with IFRAME Fallback which was posted in one of these
forums.
Now, my AjaxProvider is driven by the action parameter to call the correct
function.
The code which does the dependent list population looks like:
Sub FetchTaskAction()
Dim SQL, rqTaskType, rs
rqTaskType = CCGetParam("TaskType","")
SQL = "Select * From tblTaskActions Where TaskType = '" &
Trim(rqTaskType) &"'"
Set rs = MyDBConnection.Execute(SQL)
If rs.EOF Then
MyScript = MyScript & "addopt1('0','No Actions Available');" & vbcrlf
Else
Do Until rs.EOF
MyScript = MyScript & "addopt1('" & rs("TaskAction") &"','" &
Replace(Trim(rs("TaskAction")), "'", "\'") & "');" & vbCrlf
rs.MoveNext
Loop
End If
On Error Resume Next
rs.close
Set rs = Nothing
End Sub
This should be all you need to get going. The results are lightning fast -
totally undiscernible.
I have Ajax code performing Stored procedure calls to calcualte all sorts of
totals, which then get posted to the form, and it is so fast you don;t even
see anything happening.
addopt1 could be further abstracted to get an element as a parameter, and
both it and clearcombo could be moved into the ajax layer.
