Problems copying object to clipboard

[jpors]

Hello.

We have a problem copying an object to the clipboard.

to do this, we write: Clipboard.SetDataObject(o)
where o is our object.

Our object is inherited from UserControl.

When we try to retrieve the object from the clipboard, it is of the right type, but it is null.

The object that is added to the Clipboard needs to be serializable. eg.

[Serializable]
public class YourData
{
.
.
}

Clipboard.SetDataObject(new DataObject(new YourData()));

IDataObject dataObject = Clipboard.GetDataObject();
object data = dataObject.GetData(typeof(YourData));

What if the object is serilizable and it returns null anyway. Anyone have any idea what is wrong?

Thanks

Anders

this is the object i`m trying to place on the clipboard

[Serializable]
public abstract class PageItem : UserControl
{

}

to place the object on the clipboard, i do this

Clipboard.SetData ( "PageItem", pageItemObject ) ;

The following method call returns true

Clipboard.ContainsData ( "PageItem" ) ;

However, when i do this, it returns null

Clipboard.GetData ( "PageItem" ) ;

Can`t figure out why...

I'm sorry I dont mean to clog up your thread, I'm still very new to c#.


I just got done serializing a generic queue of struct's. In my reading it says you cant serialize an inherited class. Does that help any?

Ah, thanks for the input. That might be the problem

Well you cannot serialize a class that is inherited from a class that does not implement serializing. Therefore you can not serialize a class that inherits from UserControl.
