Hierarchical Component Editor

[JPRoot]

Hi,
When you use the Datagrid, editing TableStyles, you can add ColumnStyles using the design time editor. On the ColumnStyle design time editor, there is a Add button where there is a drop arrow where you can choose between a DataGridBoolColumn and DataGridTextBoxColumn to add.

I wish to have the same exact dialog for my components with the difference that I would like to list in that drop arrow my own types.

Actually I have a component called MyMenuSystem where I would like to add, at design time, child MyMenuSystemTextItem and MyMenuSystemButtonItem... the same way you can add DataGridBoolColumn and DataGridTextBoxColumn to a DataGridColumnStyleCollection.

How can I do this? Is it just a mather of putting some attributes to my class to have the default collection design time editor to adapt to multiple types or I must redo a complete design time control??

Hi JPRoot,

Thank you for posting in the community! Sorry for letting you wait for so
long time.

Based on my understanding, you want to add more types to your collection
property's "Add" button.(Appear as a menu button in the editor form)

================================================== ========
Actually, in .Net designer, CollectionEditor class is used to edit the
collection property. To add more types to your member "Add" button, you can
inherit CollectionEditor class and override CreateNewItemTypes() method to
return your customized types.

You can try the following Solution to see if it helps resolve your issue:

private object [] col;

[Editor(typeof(MyCollectionEditor),typeof(System.Dr awing.Design.UITypeEditor
))]
public object[] Col
{
get
{
return col;
}
set
{
col=value;
}
}

public class MyCollectionEditor :
System.ComponentModel.Design.CollectionEditor
{
public MyCollectionEditor(Type t): base(t)
{
}

protected override Type[] CreateNewItemTypes()
{
return new Type[] {typeof(MyItem), typeof(MyOtherItem) };
}
}

class MyItem
{
}

class MyOtherItem
{
}

================================================== =======
Please apply my suggestion above and let me know if it helps resolve your
problem.

Thank you for your patience and cooperation. If you have any questions or
concerns, please feel free to post it in the group. I am standing by to be
of assistance.
Have a nice day!!
