BindAt Property

  • Artículo
  Microsoft Speech Technologies Homepage

Gets or sets whether the SemanticItem control binds to the target control at the server or at the client. Read/write.

Usage

ASP.NET markup: <speech:SemanticItem BindAt="..." />
Get value: String = SemanticItem.BindAt;
Set value: SemanticItem.BindAt = String;
Data type: String
Required: No; Default: Null

Remarks

If the value of BindAt is server then binding occurs on the server; if BindAt is "", or not specified, then binding occurs on the client.

The control raises the ArgumentException under any of the following conditions:

  • The value of BindAt is invalid
  • BindAt is "server" and SemanticItem.TargetElement is not a server-side control
  • BindAt is "server" and SemanticItem.TargetAttribute is not a member of the control specified by SemanticItem.TargetElement
  • BindAt is "server" and SemanticItem.TargetAttribute is a member of SemanticItem.TargetElement, but is not of type string,
  • BindAt is "server" and SemanticItem.TargetAttribute is a string, but is read-only.
