Question

I’m attempting to make a grid based dungeon system at the moment in Visual Studio 2010. I have a main user control which contains 64 other smaller user control objects, which I’ve called GridSquares, organised into an 8×8 grid. The idea behind the grid squares is to act as potential movement spaces within the ‘dungeon’. The problem I have at the moment is that I need to be able to call a click event on the user controls (GridSquares) themselves, which have been placed on screen so I can retrieve their coordinate (name) for comparison. However the event does not work when I call it (through clicking).

I am aware that the events work when I place them within the usercontrol (GridSquare object) but I need the click even to work when the user control itself is clicked.

Given that all 64 objects placed are the same type I can not work within the GridSquare class as I require the name of the user control to be returned through the event.

I hope this makes sense but please ask if I need to explain further.

Many thanks, Liam

EDIT:
I’m not sure how much this will help or what code to display but the GridSpace controls have already been added to the ‘dungeon’ user control. Then within I add all 64 to a dictionary:

gridSpaces.Add(gs11.Name, gs11);

Where gs11 is the name of the GridSquare.

From here I tried creating event handlers for the individual user controls on the dungeon screen, which failed to call.

I think i get what your saying. Add this code to your user control:

public new event EventHandler Click {
    Add {
        base.Click += value;
        foreach(Control i in Controls) {
            i.Click+=value;
        }
    }
    remove {
        base.Click -= value;
        foreach(Control i in Controls) {
            i.Click -= value;
        }
    }
    }

this will add the click event to everything in your user control, i hope i didnt make any errors, and that this helps
