[Visual Basic]
<CategoryAttribute("Behavior")>
<DefaultValueAttribute()>
<DescriptionAttribute("When set to false, the other form elements are not included in the HTTP POST")>
Public Property UpdateAll As Boolean

[C#]
[CategoryAttribute("Behavior")]
[DefaultValueAttribute()]
[DescriptionAttribute("When set to false, the other form elements are not included in the HTTP POST")]
public bool UpdateAll {get; set;}

[C++]
[CategoryAttribute("Behavior")]
[DefaultValueAttribute()]
[DescriptionAttribute("When set to false, the other form elements are not included in the HTTP POST")]
public: __property bool get_UpdateAll();
public: __property void set_UpdateAll( 
   bool value
);

[C++/CLI]
[CategoryAttribute("Behavior")]
[DefaultValueAttribute()]
[DescriptionAttribute("When set to false, the other form elements are not included in the HTTP POST")]
public:
property bool UpdateAll {
   bool get();
   void set (bool value);
}

Return Type

If true, all values for all client-side form elements are posted to the server. If false, only the value for the callback element is posted to the server. The default value is true.

Remarks

If true, all values for all client-side form elements are posted to the server. If false, only the value for the callback element is posted to the server. This can be used to highly optimize performance depending on the application. For example, if an application has a lot of form fields with a Timer raising a periodic callback, the callback lag may be signifigant, as the script has to loop through all of the form fields to get the client-side value. However, this may not be necessary. Often, you may only need to raise a callback, and don't need the values for form fields. In this case set this property to false, and the callback will execute much faster.
