ClientScriptManager::IsOnSubmitStatementRegistered Method (String)
Determines whether the OnSubmit statement 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 OnSubmit statement to search for.
Call this method before calling the RegisterOnSubmitStatement method to avoid registering duplicate OnSubmit statements. This is particularly important if the statement requires a large amount of server resources to create.
A statement is uniquely identified by its key and its type. Statements with the same key and type are considered duplicates.
This overload of the IsOnSubmitStatementRegistered method calls the overload that takes both a key and a type parameter with the type set as a Page object
