Thank you very much!
But if I replace "EPiServer.UserControlBase" with "MyPage.Classes.DynamicContentBase" my propertied disappear. I'm not sure how to implement you class the right way.

Hi
This base class you had to register the properties by override the Properties method
but if you use this class I quess it will work as you are used to

And it's a bug in the base class. Or more like bad handy work. Since they use | as seperator and the position of the property to map it back.
My code saves the data down with the name of the property.

One more question:
Are you using DynamicContentPlugIn or do you register the control in web.config?
I get this error message: "The method or operation is not implemented" on
public virtual System.Web.UI.Control GetControl(EPiServer.PageBase hostPage) { throw new NotImplementedException(); }
Aug 27, 2012 14:26
Then i get the same error message on :
public virtual string Render(EPiServer.PageBase hostPage) { throw new NotImplementedException(); }
What i did to solve the above problem was to add:
public override System.Web.UI.Control GetControl(EPiServer.PageBase hostPage) {
var userControl = (MagazineItem)hostPage.LoadControl("~/Templates/DynamicContent/MagazineItem.ascx"); userControl.Title = Properties["Title"].Value as string;
return userControl;
}
It takes alot of extra code to write out all the properties again but it works.

I have not used that base class you are using before, but if you modify above code to some thing like this I quess that mapping will be done fore you

I'm creating DC-controls with DynamicContentPlugIn and I use Page type builder and ETF to create editor controls with DynamicContentEditControl. But I have a very annoying bug now with the values in the fields of the control. When I'm using the crontrol and leave a field empty or don't check a checkbox it uses the value from the property below. In other words, the value can't be null because then it uses the value from the next propery in line.
I am aware of the issue with moving around the order of the properties once they have values, but now the values moves around by them themselves.
Any help solving this would be much appreciated.
