I am trying to create a new property type that should be rendered as checkboxes in editmode. The type is derived from PropertyString. The property renders itself as it should but the values won't get stored in EPiServer. What kind of controls should I use and do I have to add more things like ParseToObject()? Here is some code from CreateChildControls(): CheckBoxList cbList = new CheckBoxList(); CopyWebAttributes(container, cbList); cbList.RepeatColumns = 3; cbList.RepeatLayout = RepeatLayout.Table; cbList.Items.Add(new ListItem("Value A", "a")); cbList.Items.Add(new ListItem("Value B", "b")); cbList.Items.Add(new ListItem("Value C", "c")); container.Controls.Add(cbList); container.Controls.Add(CreateParseValidator(cbList)); - Johan
