How do I Unregister 'anonymous' event handler

I have code like this:

        Binding bndTitle = this.DataBindings.Add("Text", obj, "Title");
        bndTitle.Format += (sender, e) =>
        {
            e.Value = "asdf" + e.Value;
        };

How do I now disconnect the Format event?

Answer 1

You can't do that, unfortunately. You could create a local to hold the lambda if you remove the event in the same scope:

Binding bndTitle = this.DataBindings.Add("Text", obj, "Title");
EventHandler handler = (sender, e) =>
{
    e.Value = "asdf" + e.Value;
};

bndTitle.Format += handler;
// ...
bndTitle.Format -= handler;
