If ImgRow1 is a property like:
public List<Image> ImgRow1 { get; set; }
and is in scope in the event handler, then you can modify the event handler like this:
private void item_MouseDown(object sender, MouseButtonEventArgs e)
{
Image myImage = (Image)sender;
int index = ImgRow1.IndexOf(myImage);
MessageBox.Show(index.ToString());
}
Or, You could create your own "IndexedImage" class with a ListIndex property, inheriting from Image and use that.
public class IndexedImage : Image
{
public int ListIndex { get; set; }
public IndexedImage()
{
}
}
When you add the event handler, add the list index as well:
foreach (IndexedImage item in ImgRow1)
{
item.MouseDown +=new MouseButtonEventHandler(item_MouseDown);
item.ListIndex = ImgRow1.IndexOf(item);
}
Then in the event handler you can get the ListIndex property:
private void item_MouseDown(object sender, MouseButtonEventArgs e)
{
IndexedImage myImage = (IndexedImage)sender;
MessageBox.Show(myImage.ListIndex.ToString());
}
but that has other issues, in that the index may change later on, so the class would need to be more complicated in reality.
