iOS Question How can I add a value to a dynamically created picker item

[davepamn]

I need to add a Key/Value pair for each element in the data picker.

What exactly do yo want to do ?
You could use a Map to memorize the data and display the key in the Picker.

Do you know what a Map is?
You should look at the documentation to understand what it is and how to use it.

Can a Data picker have a Key/Value pair?

My Key is different from the display for the data picker.

Are you saying that I will need to create a Map that holds the key and use the description to lookup the Key?

I would rather have the control hold the key for the item

One option is to use a Map.

Another option is to add AttributedStrings instead of Strings and then store the value in the Tag property.

                Dim oKeyValue As AttributedString
                Dim oFont As Font
                oFont=Font.CreateNew(30)
       
                oKeyValue.Initialize(sListText,oFont, Colors.Black)
                oKeyValue.Tag=sListValue

                myList.Add(oKeyValue)

AttributeString work!

On the reverse side, How do I get the tag value for the selected data picker item?

Dim attr As AttributedString = p.GetItems(Column).Get(row)
Log(attr.Tag)
