Deciphering which control fired an event

Question

I have an application with many images that all look the same and perform similar tasks: ``` ``` Now, I want to link each one to the same event handler: ``` private void image_MouseDown(object sender, MouseButtonEventArgs e) { //this_program = ???; //this_slot = ???; //slots[this_program][this_slot] = some value; } ``` Obviously the program number and slot number of the image are part of its name. Is there a way to extract this information when the event handler is fired?

Accepted Answer

Yes, it is possible.

As its name suggests, the `sender` parameter contains the object which fired the event.

You can also use the `Grid`'s attached properties for convenience to determine which row and column it is in. (It is also possible to get other attached properties this way.)

```
private void image_MouseDown(object sender, MouseButtonEventArgs e)
{
    // Getting the Image instance which fired the event
    Image image = (Image)sender;

string name = image.Name;
    int row = Grid.GetRow(image);
    int column = Grid.GetRow(image);

// Do something with it
    ...
}
```

Side note:

You can also use the `Tag` property to store custom information about controls. (It can store any objects.)
