Dyanmically calling a function in usercontrol

[phl]

hi,

I have a number of usercontrols which inherits a interface. the
function in this interface is used to provide information about the
usercontrol. I would like to call this function say when a button is
clicked.

I can do this by lot of hardcoding, as I have the usercontrol names
stored and I can call this obligatory function like this:

//loop through list of usercontorls
foreach(BLL.TicketInfo ti in TicketInfo)
{
if(ti.UserControlName.ToLower() == "EditProfile.ascx".ToLower())
{
EditProfile uc = (EditProfile)CurPage.FindControl("EditProfile");
dv.AddRange(uc.GetDisabledValidators());
}

//etc
}

while this works, it's crap because it makes adding usercontrols to my
app inconvienientm as I have to add hardcoded stuff everywhere. Just
wondering if you guys knows of a smarter way of doing this, like
dynamically. If I somehow loaded the usercontorl with the string I
have, should I be able query the function it supports by the interface
it's has inherited?

Cheers

You can loop through all the controls on your page (or panel, or whatever).
You can test to see if you have one of your user controls by checking for
the interface:

foreach (Control c in this.Controls)
{
if (c is IMyInterface)
{
((IMyInterface) c).MyFunction();
}
}

You can loop through them and do:

if (control is IUserControlDetail){
string value = ((IUserControlDetail)control).GetDetails();
}

where IUserControlDetail is the interface and GetDetails() is defined by
said interface..

the control is passed to the event as sender. you can just cast to the
interface and call the methods.

protected void button1_click(object sender, EventArgs e)
{
myInterface mybtn = sender as myInterface;
if (mybtn != null)
{
// call interface methods
}
}
