I am building a DNN Module that has multiple packages. One of the packages has 2 view modules, one for a ListView and the other for a filter (QueryExtender). The idea is to allow the user to place the ListView and filter wherever they want on a page.

I am using an EntityDataSource.

When the Data Source, ListView and filter (QueryExtender) are in the same control (.ascx file), it works just fine. But when the ListView and filter (QueryExtender) are put in two separate controls (.ascx files), for example Filter.ascx and ListView.ascx, it doesn't work.

Not sure how to approach this. Any ideas?

Why you do not want to use 2 different modules and to pass data between them? Each DNN module has only one Primary control (with a lot of subcontrols inside) with type "View".

Another possible solution for you is to have single control with type View. Inside of this control you can have 2 subControls: Control1 and Control2. Also in the settings you can define what control should be displayed for current instance of the module. It should work, but this is not "clear" solution. I prefer to build 2 different modules and to pass data between them.

Finally got it working. I'm not sure why it would work with hard coded values and not with variables, but if you call 'rebind' on the QueryExtender right after you add the Expressions/parameters to it, it works with variables perfectly. Now I can move the Filter and Results ListView to any pane on the page.

In case someone ever wants to do something similar, here is how it works:

I used 2 view controls with IMC. The Sender has all the input controls (dnnTextBoxes and dnnComboBoxes) and a dnnRadButton. A collection of Expressions is built in the codebehind when the button is clicked. The Sender then uses IMC to pass the collection to the Listner. The Listner has the Entity Data Source, a ListVIew and an empty QueryExtender. When the Listner receives the message, it loops though the collection adding the Expression objects to the QueryExtender, and finally calls the QueryExtender's rebind method.

 If anyone has a better solution for a Filter and Results that can be moved to any pane on the page, please let me know.
