It is not a good thing to mention your fully functions in the querystring.
It´s better to pass a string by the querystring and in the page_load event
get that string and do the right action then. Also you can put parameters in
the querystring and get them in the same event.

i agree with that 100% !
the problem is hat the client side was wrote long ago and know i cant change
it
so how can i call a function dynamiclly?

 

[IfThenElse]

string methodToCall = "TheFunctionOrMethodNameToCallDynamicall";
Return CType(Me.GetType().InvokeMember(methodToCall, BindingFlags.Instance
Or BindingFlags.Public Or _

BindingFlags.InvokeMethod, Nothing, Me, New Object()
{SomeParameterYouArePassing_Id, SecondParameterEtcAndThirdCommaDelimited}),
Byte())



In this case I am invoking, Dynamically, a function that returns a Byte()
Array.



Etc..

This is an example.

string methodToCall = "TheFunctionOrMethodNameToCallDynamicall"; // put
the function name you want to call here.

Return CType(Me.GetType().InvokeMember(methodToCall, BindingFlags.Instance
Or BindingFlags.Public Or BindingFlags.InvokeMethod,
Nothing, Me, New Object()
{SomeParameterYouArePassing_Id,
SecondParameterEtcAndThirdCommaDelimited}), Byte())

This is where you pass the parameters if you have any.
{SomeParameterYouArePassing_Id, SecondParameterEtcAndThirdCommaDelimited}),

The function you are calling is withing the same class hence
Me.GetType().etc.....
