Input Area
An Input Area allows end-users to input tokens.
Input Area style settings can be customized using the ASPxTokenBox.TokenBoxInputStyle property.
If no token is specified and the editor is not focused, the Input Area can display prompt text, which is specified by the ASPxAutoCompleteBoxBase.NullText property. The prompt text disappears when the editor receives focus.
<dx:ASPxTokenBox ID="MyTokenBox" runat="server" NullText="Select contacts...">
