PropertyEditor.NullText Property

Specifies the text that a Property Editor displays when its value is null or String.Empty. WinForms Property Editors also show this text if their value is DBNull.Value.

Namespace: DevExpress.ExpressApp.Editors

Assembly: DevExpress.ExpressApp.v20.1.dll

Declaration

public virtual string NullText { get; set; }
Public Overridable Property NullText As String

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 platform-agnostic View Controller shows how to specify this property for the "Address1" Property Editor in the Contact Detail View.

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.
