I'm trying to initialize a dropdown type list with a selection already shown.
I have a service that returns a list in the following format: returned list with selection
When I use it on a mashup with a list item, the "selected" item is not displayed upon list loading.
loaded list, no selection
How can I make it so the list initializes with the selected rows returned by my service?
Solved! Go to Solution.
I managed to make my list select a row using my "isSelected" property through the use of a validator and an expression.returned infotable
validator checks it isSelected is true
if isSelected is true, expression takes selected property
selected property is set as selectedText in list
list with specific selection on load
However, this only works for the first row of data returned by my service, is there a way to iterate over the returned data in the mashup so that my validator checks all rows of returned data?
Hi, the "isSelected" is just a Boolean property in your Infotable result, it can be renamed to any words so it won't affect how List or this Infotable behaves.
The List has "AutoSelectFirstRow" setting, and also agrees to the SelectedRow(s) selection in the Infotable result from the source service. If the row you want is selected in the service, it will also shown as been selected in the List widget.

If my understanding is correct ,you want to show both the property ("property" and "isSelected" ) in list widget ? If yes ,then you should use grid widget to show your all data as list display any one property which is selected in "DisplayField" and "ValueField" property attribute of List .
Let me know if this understanding is not correct .

I actually want the list to use the "isSelected" property as a way to show selected rows on mashup load
