Property Value

Type	Description
String	A text that a Property Editor displays when its value is null, String.Empty, or DBNull.Value (WinForms only).

Remarks

The following View Controller created in the MySolution\Module\Controllers folder shows how to specify this property for the “Address1” Property Editor in the Contact Detail View.

C#

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Editors;
// ...
public class CustomizeNullTextValueController : ObjectViewController<DetailView, Contact> {
    protected override void OnActivated() {
        base.OnActivated();
        PropertyEditor propertyEditor = View.FindItem("Address1") as PropertyEditor;
        if (propertyEditor != null) {
            propertyEditor.NullText = "Type your text here…";
        }
    }
}

The following image illustrates the result.

Note

You can also set the NullText property in the Model Editor.
