HtmlForm.Method Property

Gets or sets a value that indicates how a browser posts form data to the server for processing.

[Visual Basic]
Public Property Method As String
[C#]
public string Method {get; set;}
[C++]
public: __property String* get_Method();
public: __property void set_Method(String*);
[JScript]
public function get Method() : String;
public function set Method(String);

Property Value

A string that indicates how a browser posts form data to the server. The default value is POST.

Remarks

Use this property to specify how the browser sends form data to the server for processing. The two common methods supported by all browsers are GET and POST.

CAUTION   You can override the default value of this property and use the GET method instead of POST. However, since GET requests are limited in how much data they can include, using the GET method can cause the post back and state management capabilities provided by the Web Forms page framework to fail.

Example

[Visual Basic, C#] The following example demonstrates how to use the Method property to specify that form data is posted back to the server.
