How to insert a combobox CustomEditor for a property that is a foreign key ID

[Silvio]

Hi,

I have a PropertyGrid that edits an object that has an int property that represents a foreign key to a particular list of objects.

Let's say for example that the objects referenced by this foreign key have this type:

class Article

{

public int ID {get; set;}

public string Code {get; set;}

}

Let also say that I have a repository that returns the list of all articles:

IEnumerable<Article> Articles

{

get;

}

Suppose the object passed to the ProperyGrid has a property like this:

int ArticleID {get; set;}

How is it possibile to change the default behaviour of PropertyGrid on property named "ArticledID"?

I don't want, in fact, an integer textbox edit, but instead I'd like to a have a ComboBox populated by "Articles" repository property, showing the "Code" property as Display property but using the "ID" property as Value property.

Thank you in advance.

Silvio

Hi Silvio, 

Thank you for contacting Syncfusion support. 

The ComboBox can be added to the Property grid using the CustomEditorCollection property. We need to implement a Custom editor with ITypeInterface. Please refer the code example for adding ComboBox in ArticleID property. 

[C#] 

 

pgrid.SelectedObject = new Article(); 

CustomEditor editor = new CustomEditor(); 

editor.Editor = new ComboEditor(); 

editor.Properties.Add("ArticleID"); 

this.pgrid.CustomEditorCollection.Add(editor); 

pgrid.RefreshPropertygrid(); 

We have prepared sample for the sample which is available in the below location.
