DevExpress ASP.NET Combo Box supports Null Text (coming soon in v2013 vol 1)

ASP.NET Team Blog
13 May 2013

Starting with the first major release for DXperience in 2013, you’ll be able to set null text for the DevExpress ASP.NET Combo box control.

What? What’s this NullText?

NullText is grayed out text inside of an editor that gives your website visitor a hint as to what they should or could input:

DevExpress ASP.NET Editors NullText

ASPx ComboBox NullText

Here’s the DevExpress ASP.NET Combo box control with the Null Text property set to "Start typing here…”:

To use this great little feature, simply set the NullText property on the control:

DevExpress ASP.NET Editors NullText Property

Or through the source code:

Define NullText

It may seem odd to call this feature Null Text,  instead of Hint Text, Default Text, or something else. But read this definition:

The NullText property value is displayed in the edit box when the editor's edit value is set to null or System.DBNull.Value.

Then you’ll realize:

  1. Programmers were involved in this definition.
  2. Programmers are never wrong. Smile
