Input capable list using Repeater widget

Absolutely, I actually did an example like this with a repeater widget. It isn't posted in Downloads.
But how I have done it, is I have a ThingWorx DataTable. I use a service to retrieve the rows. Then I bind that to the repeater widget.
The Mashup tied to the Repeater widget retrieves each row based on the Key but you could just as well have it display the Info table being passed in.
To do the updates, I use a button that toggles a Session Parameter, which then fires a Service in the Parent mashup that contains the repeater widget to update the DataTable (Or any info table of data)

I'm not sure if what I wrote makes sense, let me know if you need more information and How To.

Thank you Pai, for all the help.  In your earlier reply, how would you use the button in the Mashup that is tied to the Repeater widget ?  In other words how would you detect that something changed ?   Will it fire the service in the parent for each line change ?

Hi Vish, I use a button that toggles a Session Property in the parent mashup and then I use the Session Property Changed event to fire the actual table Add/Update inside the repeater mashup. This way I can trigger it outside of the repeater Mashup but have it act within it.

Thank you for the reply Pai.  I do need some clarifications.  Is the button in the Mashup ?  If so, how is it fired ?  I would like capture the changes to the list as the user keys into a text box in the Mashup.   If you are using the Session Property Changed event on the parent, how are you passing the changed data to the service ?  I am using a Infotable in my example.

My button triggers a service that checks the Session Property. If it is false it sets it to true and vice versa.

Please do provide me an example.  That will really help.
So you have a mashup parm of type Infotable.  I was using a Infotable column to pass between the repeater and the mashup.  Thank you

Hi Vish, I put the example in our Downloads section. Please note that there are probably other ways to do this that might work even better. I believe I have some redundancy build into this example. It is called ThingWorx DataTable Editor using a Repeater Widget Example

Appreciate your help.  Will let you know soon.

Having trouble importing one of them "Data Table Thing: CGCEMTasksTable has an invalid data shape.

Pai, I think I got this working.  However, it appears that I would need to use a button WITHIN the mashup to alert (using Session Updater prop) the parent (that contains the repeater) that a row was changed - and then the parent would process the "selected" row (session prop change event).   

Is there any other way to auto detect a change (row-col) without requiring the user to click the button ?
