ClientScriptManager.IsStartupScriptRegistered Method (String)
.NET Framework (current version)
Determines whether the startup script is registered with the Page object using the specified key.
Assembly: System.Web (in System.Web.dll)
Parameters
- key
-
Type:
System.String
The key of the startup script to search for.
Call this method before calling the RegisterStartupScript method to avoid registering duplicate scripts. This is particularly important if the script requires a large amount of server resources to create.
A startup script is uniquely identified by its key and its type. Scripts with the same key and type are considered duplicates.
This overload of the IsStartupScriptRegistered method calls the overload that takes both a string key and a type parameter with the type set as a Page object
