Question

I am adding Context Items for a Context Menu and showing the required Items where necessary for the user based on user selection. I would like to show these context items for the user NEW and CLOSE..

I did some thing like

ContextMenu.Add(NEW)
ContextMenu.Add(CLOSE)

But I am getting this in sorted order like CLOSE first and NEW last . But I need to display NEW first and CLOSE last. Is it possible to do.

This (very basic code) should do it. Place following code in the constructor of your Form:

var contextMenu = new ContextMenu();
contextMenu.MenuItems.Add(new MenuItem("New"));
contextMenu.MenuItems.Add(new MenuItem("Close"));
this.ContextMenu = contextMenu;

Note: you still have to add the events yourself… 🙂

Update:

To add events to the items you’ll have to declare them in a variable instead of passing them directly in the Add() method for the MenuItems. So the previous code will look like this:

var contextMenu = new ContextMenu();

var itemOne = new MenuItem("New");
itemOne.Click += ContextMenuItemClick;
contextMenu.MenuItems.Add(itemOne);

var itemTwo = new MenuItem("Close");
itemTwo.Click += ContextMenuItemClick;    
contextMenu.MenuItems.Add(itemTwo);

ContextMenu = contextMenu;

As you can see, bot items have the same eventhandler for the Click-event. In that event you check which item was clicked. That code looks like this:

private void ContextMenuItemClick(object sender, EventArgs e)
{
    var selectedItem = (MenuItem)sender;
    switch(selectedItem.Text)
    {
        case "New" : //do some new stuff
            break;
        case "Close": //do some closing stuff
            break;
    }
}

Note that you could also set a separate eventhandler for each item in the menu, but then you end up with lots of methods for basically the same stuff… 🙂 Hope this helps!

Update2:

With all the help I gave, you normally should have been able to achieve this by yourself, not? 🙂 Anyway, for a separate handler the code will look like this:

itemOne.Click += itemOne_Click;
itemTwo.Click += itemTwo_Click;

private void itemOne_Click(object sender, EventArgs e)
{
    //do the new stuff
}

private void itemTwo_Click(object sender, EventArgs e)
{
    //do the closing stuff
}

Update3:

If you gave proper names to the menuitems you already added, you can change the order using the Index-property. Say I have following menuitems added to a ContextMenu:

var itemOne = new MenuItem("New") { Name = "NewItem" };
var itemTwo = new MenuItem("Close") { Name = "CloseItem" };

The ‘NewItem’ will be the first item and the ‘CloseItem’ will be the second. Now if I want to change the order without touching previous code you can do this:

contextMenu.MenuItems["NewItem"].Index = 1;

This will set the ‘CloseItem’ as the first and the ‘NewItem’ as the second. If you have more than 2 items, you better set the Index-property for each item individually.
