Registers a startup script block for every asynchronous postback with the ScriptManager control and adds the script block to the page.
Public Shared Sub RegisterStartupScript ( _
page As Page, _
type As Type, _
key As String, _
script As String, _
addScriptTags As Boolean _
- page (Page)
The Page object that is registering the client script block.
- type (Type)
The type of the client script block. This parameter is usually specified by using the typeof (C# Reference) operator (C#) or the GetType Operator operator (Visual Basic) to retrieve the type of the control that is registering the script.
- key (String)
The string that uniquely identifies the script block.
- script (String)
The script literal.
- addScriptTags (Boolean)
A Boolean value that indicates whether to enclose the script block with <script> tags.
Registering a startup script block with this method causes the script to be included each time an asynchronous postback occurs. To register a script block for a control that is inside an UpdatePanel control so that the script block is registered only when the UpdatePanel control is updated, use the RegisterStartupScript(Control, Type, String, String, Boolean) overload of this method.
If you are registering a script block that does not pertain to partial-page updates and you want to register a script block only one time during initial page rendering, use the RegisterStartupScript(Type, String, String) method of the ClientScriptManager class. You can get a reference to the ClientScriptManager object from the ClientScript property of the page.
