Hur gör man ( EPiServer.Web.PropertyControls )
Tillägg
Mitt problem är alltså att kontrollen (ingen av dess element förutom det namn jag tilldelat densamme i instansen av editfältet) inte ens visas i Epi's edit läge.
Någon borde ha en hum om detta ?
Tillägg 2 är att jag inte heller provat att göra liknande saker i tidigare versioner av Epi vad jag kan minnas, men jag tänker att någon kanske har en idé iallafall. Gör jag tex ett "typiskt" .NET fel, eller är det EpiServer som buggar eller vad ?

You're missing the PageDefinitionTypePlugIn attribute.
Your code should look similar to this model:
#16506
[Serializable]
[PageDefinitionTypePlugIn(DisplayName="Name of your custom control")]
public class MyCustomControlCore : EPiServer.Core.PropertyString
{
public override IPropertyControl CreatePropertyControl()
{
return new MyCustomControl();
}
}
public class MyCustomControl : EPiServer.Web.PropertyControls.PropertyStringControl
{
/*
Override CreateXXXControls to control the appearance of the property data in different rendering conditions.
public override void CreateDefaultControls() - Used when rendering the view mode.
public override void CreateEditControls() - Used when rendering the property in edit mode.
public override void CreateOnPageEditControls() - used when rendering the property for "On Page Edit".
*/
}

Ok
So you mean that the special type of control that I /describe/want to do/ should work if I do like you do recommend ?
Why are simpler properties working then ?
Is there any explanataion to that ?
See my earlier :
"
Jag har gjort flera hemsnickrade Properties i nya EpiServer (som ärrver ifrån EPiServer.Web.PropertyControls.PropertyStringControl), och har då använt mig av kontroller i stil med:
System.Web.UI.HtmlControls.HtmlSelect som den kontroll jag visar i Edit läget.
Inga problem, funkar precis som det skall.
När jag däremot försöker att skapa en helt egen control (som består av lite javascript, html element etc) kommer inte detta ut på sidan, vad är det jag missar eller inte förstår här ?

Hi!
I have investigated this some and have no problem with adding sub controls to the property. I do, however, get some problems with load order of posted data which means that the data is not updated correctly. I have not yet had time to solve this problem but I'll post the code I have used so far as it might you get you started. (We have other properties that uses sub controls that does not have this problem but I havn't found the difference yet.) In my code I have just customized the built in PropertyStringControl but just take the code and make a custom property out of it...
using System;
using System.Collections.Generic;
using System.Text;
using System.Web.UI.WebControls;
using EPiServer.Core;
namespace EPiServer.Web.PropertyControls
{
///
/// Property control that stores a short string (less than 255 characters).
///
public class PropertyStringControl : PropertyTextBoxControlBase
{
private MyCustomWebControl _innerControl;
public override void CreateEditControls()
{
_innerControl = new MyCustomWebControl();
_innerControl.Value = PropertyData.Value == null ? String.Empty : PropertyData.Value.ToString();
Controls.Add(_innerControl);
}
public override void ApplyEditChanges()
{
SetValue(_innerControl.GetValue());
}
}
public class MyCustomWebControl : WebControl
{
private string _value;
private TextBox _inputBox;
public TextBox InputBox
{
get { return _inputBox; }
set { _inputBox = value; }
}
public string Value
{
get { return _value; }
set { _value = value; }
}
protected override void CreateChildControls()
{
_inputBox = new TextBox();
_inputBox.Text = Value;
Controls.Add(_inputBox);
}
public string GetValue()
{
EnsureChildControls();
return InputBox.Text;
}
}
}

I think that I have finally found the solution to the problem with loading posted data. Add the INamingContainer interface to your web control (in this case MyCustomWebControl) like this:
public class MyCustomWebControl : WebControl, INamingContainer
