I have been working over Sitefinity 4 since it has been launched. Few days back I ran into a situation where we needed to have collection (Dictionary, List etc) to be persistent in widget`s designer view, so that properties could be added, deleted existing options etc.

Here is a quick way to do that...

In the UserControl, we do like:

private Dictionary<string, string> _TestProperty = new Dictionary<string,string>();

public string TestProperty

get

JavaScriptSerializer serializer = new JavaScriptSerializer();

if (_TestProperty.Count == 0)

_TestProperty.Add("val1", "abc");

_TestProperty.Add("val2", "xyz");

return serializer.Serialize(_TestProperty);

set

JavaScriptSerializer serializer = new JavaScriptSerializer();

_TestProperty = (Dictionary<string, string>) serializer.Deserialize(value, typeof(Dictionary<string, string>));

And here is what we do in designer js file:

var data = this._propertyEditor.get_control();

var value = Sys.Serialization.JavaScriptSerializer.deserialize(data.TestProperty);
