Hey, I want a single sub to take care of all the links in a page, by using Private Sub Links(..) Handles Link1.Click, Link2.Click How am I going to know in the sub wich link the user pressed? I can make seperate subs, but I wanted to know if I can do it like this. So, can I? ------------- Gone.. |

i wouldnt think thats possible, as the sub would have absolutely no idea what they clicked... just save yourself time and write seperate functions (after all, if you want to know which is click, then you must be wanting to do different things) ------------- Contribute to the working anarchy we fondly call the Internet |

Are you sure? In VB6 (a long time ago..) they had things like If Case = "" and stuff. Is that completely gone in .NET? I'm not sure. I'll keep trying, but idd, I already created seperate subs, wich is nog a big deal, but still, it supports multiple handles, so it must SOMEHOW know wich link is pressed. ------------- Gone.. |

Can't you index controls so it would be something like Private Sub Link_Click(Index As Integer) Handles link.click Mart. |

Uhh, no. It must always look like this Private Sub Link_Click(sender As System.Object, e As System.Eventargs) Handles link.click That's because the framework always sends those values, and it will result in an error if you don't have a sub looking like this.. ------------- Gone.. |

yea i know i couldnt be bothered writin all that out, like this then: Private Sub Link_Click(Index As integer, sender As System.Object, e As System.Eventargs) Handles link.click And on the links put Index="0" etc. Does that work? Mart. |

I don't think so, since you can't tell wich stuff should be send to the sub when it is clicked, since the framework does that. Or I would have to crack the framework and stuff, but thats a bit to much I guess. ------------- Gone.. |

Nooo like in VB you put all the controls in a Index array and the Index value of: Private Sub Link_Click(Index As integer, sender As System.Object, e As System.Eventargs) Handles link.click changes to the control that was clicked. |

i am still wondering why you wouldn't use different functions since the buttons (obviously) do different things.... seperating the logic seems to make a hell of a lot more sense than doing a case statement inside one function not trying to be difficult on this thread, just severely questioning the logic ------------- Contribute to the working anarchy we fondly call the Internet |

A link button can't accept index stuff. ------------- Gone.. |

The point is, they all do the same thing. But have this litte parameter wich needs to be set wich is different. The midbar is made out of 11 linkbuttons, which are all dynamic. If I would have to write the code at each page, for each sub, that will add up to about 400 lines of code per page.. ------------- Gone.. |
