BC40000 : 'Public Overridable Sub RegisterStartupScript(key As String, script As String)' is obsolete: 'The recommended alternative is ClientScript.RegisterStartupScript(Type type, string key, string script). http://go.microsoft.com/fwlink/?linkid=14202' in Reports.aspx.vb(42, 0)

the 2 functions are obsolete, however it will not stop you from running the application i guess.
you can change the functions to the recommended one like for IsStartupScriptRegistered("Startup")) use ClientScript.IsStartupScriptRegistered("Startup"))
and same for the second one.

Thanks Sameer, You are correct it doesn't stop me running the application but need to eliminate the warning as well ...so i tried this

IsStartupScriptRegistered("Startup")) use ClientScript.IsStartupScriptRegistered("Startup")) works fine ..........but when i use change the second line
RegisterStartupScript("Startup", scriptString.ToString) to ClientScript.RegisterStartupScript("Startup", scriptString.ToString)

I get the following error..
overload resolution failed because no accessible 'RegisterStartupScript' accepts this number of arguments :(

SameerJagdale

try this:
ClientScript.RegisterStartupScript(typeof(string),"Startup", scriptString.ToString)

ASKER

says 'string' is a class type and can't be use as an expression

SameerJagdale

change the first parameter to:
typeof(Page) and try

Kerau

ASKER

It says type is expected ..suggests me as typeof(Page)Is??????
