how to get the displayed value from a field

[atomatom]

I have a ListGrid which is using an optionDataSource and I wanted to retrieve the displayed value.

I found that I can get the ListGridField's valueMap through

	Map valueMap = field.getAttributeAsMap("valueMap");

and get the displayed value from the map.

Is there a better way to do this, or is this reasonable?

What component do you want to use for the map?

ComboBoxItem SelectItem ?

It was a SelectItem I believe.

You can use the following:

        SelectItem item = new SelectItem("theField");
        ufNatal.setDisplayField("name_of_display_on_option_datasource");
        ufNatal.setValueField("name_of_value_on_option_datasource");

On option datasource set the fields you want to both display and use as value.

Hope that helps.

Cheers,
EJ

Thank you for trying to help, but I don't think that solves the problem.

Say I have a record that is currently being displayed by the SelectItem. I can grab the value from the Select item, since that is the only thing that is actually stored in the record. But how can I get the displayed value? That is what I was using the map for, as above. I'm not sure there is an API to do this - aside from doing a fetch on the option DataSource to do the lookup, which I think is probably the more correct solution than grabbing the valuemap.

How is your optiondatasource defined?

What about the main datasource?
