ValuesToJsonArray from MultiCombo issue

[zfreeman]

I just upgraded from 1.3 to 2.0 and I'm able to get through most of the issues via your change notes and other threads but I can't find anything about this one. I am grabbing the values from a MultiCombo and putting them into a string before storing them. What I previously did was this:

string mentorAreas = mcMentorAreas.SelectedItems.ValuesToJsonArray().To String();

But now I am getting the following error:

Error 324 'Ext.Net.ListItemCollection' does not contain a definition for 'ValuesToJsonArray' and no extension method 'ValuesToJsonArray' accepting a first argument of type 'Ext.Net.ListItemCollection' could be found (are you missing a using directive or an assembly reference?)

Is there a new way to handle this? How can I grab all the values from a MultiCombo and store them in a string?

Hi @zfreeman,

Apologize for the long delay.

Thanks Danil!

Just to be clear, I would just add the method you wrote out into my code and then where I used to do this:

string mentorAreas = mcMentorAreas.SelectedItems.ValuesToJsonArray().To String();

I would now do this:

string mentorAreas = ValuesToJsonArray(mcMentorAreas.SelectedItems);

Yes, that is correct.

Finally, we have added the following breaking change item.

158. The type of the ComboBoxBase's and MultiSelectBase's SelectedItems property has been changed to the ListItemCollection class.

There is no ToJsonArray method in the ListItemCollection class. Use this code if needed.

JSON.Serialize(ComboBox1.SelectedItems);

There are also no IndexesToJsonArray and ValuesToJsonArray methods.

You can implement them yourself, they are simple. Here is an example of ValuesToJsonArray implementation.
