Interface Widget for Custom Data
I was trying to get the Custom Interface widget when creating a custom field to work. I followed the steps on this post:
www.sitefinity.com/.../using-a-custom-interface-widget-when-creating-a-custom-field.aspx
but am still getting an "Exception
has been thrown by the target of an invocation." when trying to save the
new metafield. I think the error may lie where I put the nulls but I am not sure what values are supposed to go in there. Is there a working example that I could use otherwise?
using System;using Telerik.Sitefinity.Web.UI.Fields;using Telerik.Sitefinity.Web.UI;namespace Telerik.Sitefinity.Samples [FieldDefinitionElement(typeof(GenericCustomFieldEditorDefinitionElement))] class AssociatedImage : CompositeFieldControl protected override System.Web.UI.WebControls.WebControl TitleControl get throw new NotImplementedException(); protected override System.Web.UI.WebControls.WebControl DescriptionControl get throw new NotImplementedException(); protected override System.Web.UI.WebControls.WebControl ExampleControl get throw new NotImplementedException(); protected override void InitializeControls(Web.UI.GenericContainer container) throw new NotImplementedException(); protected override string LayoutTemplateName get throw new NotImplementedException(); public class GenericCustomFieldEditorDefinitionElement : Telerik.Sitefinity.Web.UI.Fields.Config.FieldControlDefinitionElement, Telerik.Sitefinity.Web.UI.Fields.Contracts.ITextFieldDefinition public GenericCustomFieldEditorDefinitionElement(Telerik.Sitefinity.Configuration.ConfigElement parent) : base(null) public override DefinitionBase GetDefinition() return null; public int Rows get throw new NotImplementedException(); set Rows = value; public string HideIfValue get throw new NotImplementedException(); set HideIfValue = value; public Telerik.Sitefinity.Web.UI.Extenders.Contracts.IExpandableControlDefinition ExpandableDefinition get throw new NotImplementedException(); Hi ,
Can you provide the stack trace of the error? Also in your classes the methods are not implemented at all.

Hi Ivan,
Thank you for your response. I was actually able to find out how to create custom metafields from this post:
