PostBack once all lists in CascadingDropDown are selected

Has anyone found a way to generate a postback once all lists in a CascadingDropDown have a valid selection.

I am converting a web app that has many places where the user has to select Software, Version, Terrain and Course (It's a Virtual Reality Cycling Portal) Previously each selection caused a postback to populate the next list. On each post back the state of the page may need to changed, in terms of different controls being visible to capture either the riders time or the distance they cover.

I have switched to using Atlas and created a UserControl with the CDD to reduce the postbacks, but I still need to change the state of the controls with a postback, as I need to lookup details of the course to determine which controls should be visible.

So what I need to do is generate a postback once all lists have a valid selection. As a last resort I can turn the Ride Upload tool I am referring to into a wizard, but I would prefer to keep the new UI similar to the original single form one users are already using.

The user control is working great in all but this one scenario, as the other scenarios all require the user to click on a button to trigger the update of a data control.

Once the last CDD gets a selection, you know that all the CDDs have a selection - might you be able to tag the last CDD with AutoPostBack? Alternatively, maybe you could write a little bit of JS to run on the client side and hook the onchange event of the DDL and do the postback manually?

Problem converting inserted html to ajax client control

Hi,

im inserting a htmltable which is returned by a webservice into a div container.
My problem is that i am not able to create a client control out of this htmltable (or its child elements)
although its inserted properly. It seems that inserted HTML is not available in the dom right after insertion.
Any suggestions?

thank you!

Problem converting from Atlas beta to Ajax

Hi,

I have an application that uses the Modal Popup Extender control. I developed it using the beta of Atlas, and now I'm trying to convert it to version 1.0 of Ajax.

I've removed the Atlas references and added the one for the AjaxControlToolkit. I replaced the Atlas ScriptManager tag with the new ASP:ScriptManger tag, and I replaced the Atlas ModalPopupExtender and ModalPopupProperties tags with the Ajax ModalPopupExtender tag. When I try to run the program, I get a Javascript error which says 'Sys' is undefined, and refers to the following code added at runtime:

Sys.Application.initialize();
Sys.Application.add_init(function() {
$create(AjaxControlToolkit.ModalPopupBehavior, {"CancelControlID":"rpPermitsPlus_ctl00_OkButton","DynamicServicePath":"/PP_ServiceWorkTicket.aspx","PopupControlID":"rpPermitsPlus_ctl00_pnlTennantStatus","id":"rpPermitsPlus_ctl00_mpeTennantStatus"}, null, null, $get("rpPermitsPlus_ctl00_btnReport"));

Can someone tell me what I've done wrong, and what I need to do to get this application working again? Thanks for your help!

You need to edit your web.config in multiple places as well. I would suggest you compare the sample web.config in the ASP AJAX with your own.
That did it. Thanks kp0!
