AutoPostBack Property

  • Artigo
  Microsoft Speech Technologies Homepage

Gets or sets whether the SemanticItem control posts back to the server when its binding event is detected. Read/write.

Usage

ASP.NET markup: <speech:SemanticItem AutoPostBack="..." />
Get value: Boolean = SemanticItem.AutoPostBack;
Set value: SemanticItem.AutoPostBack = Boolean;
Data type: System.Boolean
Required: No; Default: False

Remarks

The BindOnChanged property specifies the binding event.

The SemanticItem control conforms to the ASP.NET event model. For more information on events, autopostback and event delegation in ASP.NET, see ASP.NET Server Control Event Model.
