Registers the startup script with the System.Web.UI.Page object using a type, a key, a script literal, and a Boolean value indicating whether to add script tags.
Syntax
Parameters
- type
- key
- script
- addScriptTags
Remarks
A startup script is uniquely identified by its key and its type. Scripts with the same key and type are considered duplicates. Only one script with a given type and key pair can be registered with the page. Attempting to register a script that is already registered does not create a duplicate of the script.
Call the erload:System.Web.UI.ClientScriptManager.IsStartupScriptRegistered method to determine whether a startup script with a given key and type pair is already registered and avoid unnecessarily attempting to add the script.
In this overload of the erload:System.Web.UI.ClientScriptManager.RegisterStartupScript method, you can indicate whether the script provided in the script parameter is wrapped with a <script> element block by using the addScriptTags parameter. Setting addScriptTags to true indicates that script tags will be added automatically.
The script block added by the erload:System.Web.UI.ClientScriptManager.RegisterStartupScript method executes when the page finishes loading but before the page's Control.OnLoad(EventArgs) event is raised. The script blocks are not guaranteed to be output in the order they are registered. If the order of the script blocks is important, use a System.Text.StringBuilder object to gather the scripts together in a single string, and then register them all in a single client script block.
