Hello Roy,
Currently, our DataForm support only binding to CLR objects. What it currently lack is a suitable extension point to plug the custom generation logic as it currently it requires PropertyInfo properties. However, with the upcoming release (in the mid of Septemeber) we will add an extension point.
With the updated version you would be able to use the following snippet:
public class JSONMetadataProvider : PropertyMetadataProviderBase
{
private List<EntityProperty> entityProperties = new List<EntityProperty>();
public override List<EntityProperty> EntityProperties
{
get
{
return entityProperties;
}
}
public override void Initialize(object source)
{
var data = JObject.Parse(source.ToString());
foreach (JObject item in data["questions"])
{
foreach (var jProperty in item.Properties())
{
var metadata = new EntityPropertyMetadata()
{
Group = ...,
Header = ...,
PropertyType = ...,
PropertyType = ...,
...
};
var property = new JsonEntityProperty(jProperty, item, metadata);
}
}
}
}
public class JsonEntityProperty : EntityProperty
{
private JProperty property;
public JsonEntityProperty(JProperty property, object item, EntityPropertyMetadata metadata) : base(property, item, metadata)
{
this.property = property;
}
public override object OriginalValue
{
get
{
return property.Value;
}
}
public override void Commit()
{
//TODO: implement
throw new NotImplementedException();
}
}
The setup of the DataForm will look like that:
We will also issue an article describing the specific case of binding the json.
Thank you for bringing the use case to our attention. I have updated your telerik points acordingly
