Question

I want to pass buttonClick method as a parameter to the function:
we have

buttonClick:

private void iDeactivate_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
{
 ...
}

function:

private void AddItemToPopUpMenu(GridViewMenu cMenu, string cItemCaption, EventHandler cClickHandler, Image cItemImage, bool cItemBeginGroup)
{
    DXMenuItem item = new DXMenuItem();
    item.Caption = cItemCaption;
    item.Click += new EventHandler(cClickHandler); //problem there
    item.Image = cItemImage;
    item.BeginGroup = cItemBeginGroup;
    cMenu.Items.Add(item);
}

So can someone suggest solution?

tried:

AddItemToPopUpMenu(cMenu, iDeaActive.Caption, iDeactivate_ItemClick, null, false);

and changing function parameters to:

private void AddItemToPopUpMenu(GridViewMenu cMenu, string cItemCaption, EventHandler<ItemClickEventArgs> cClickHandler, Image cItemImage, bool cItemBeginGroup)

but then I get mistake in code where I have marked “problem there”

So is it possible to pass buttonClick method, without changing it parameters?

Edit:
As I see some wrong answers, so should say that Ihave to pass as a parameter because AddItemToPopUpMenu is called several times, every time with different methods

Answer 1

By the look of it, DXMenuItem.Click only supplies a regular EventArgs object and such can only work with regular EventHandlers.

You’re trying to get a specialized DevExpress.XtraBars.ItemClickEventArgs object in your handler, and the event just doesn’t supply it.

I don’t think what you’re trying to do is possible. You either need to reduce your handler so it only needs a regular EventArgs, or you need to find a type of button whose Click event supplies an ItemClickEventArgs.
