Multiple Controls

[Thom Little]

Using Windows Form C# in .NET 3.5

I have 12 controls on a form. When one of them is clicked I want a common
event handler to do the processing and substitute a single property on the
form. There is a different value for the property in each control.

Is there a standard way to determine which control was clicked and to make a
substitution like this one? Can you point me to an example?

Re: Multiple Controls

You can find which button was called by casting "sender" to Button.
For the property, well - I guess Tag would be a suitable place to
store extra info - i.e. set the Tag of each button to the required
value:


void SharedHandler(o bject sender, EventArgs args) {
Button btn = sender as Button;
if(btn == null) return; // wtf?
this.SomeProper ty = (string)btn.Tag ; // subst with desired type of
SomeProperty
}

(oh, replace "Button" with "Control" if you meant any control; I had
Button on the brain...)
