C# distinguish Drag drop and Mouse click

Question

I have a form which allows drop and also I need to capture the click event.

The tricky part here, is when the user drags and drop the object on the form, the MouseClickEvent also fired-because he also clicked the mouse to release the drop.

How may I handle each on of this events in a separate event trigger?

Thanks in advance!

This is a short and more logic question so i didn't see a real reason to put pieces of code here..

Thanks!

A global (boolean) variable delivers an easy and reliable solution for these situations. — varocarbas, Sep 03 '15 at 19:47

Add a global boolean, for instance:

private bool isDragAndDrop;

Set it to false when loading the form. When the dragAndDrop event is fired you should set isDragAndDrop = true.

When the Click event is fired you check if(!isDragAndDrop) This will or will not execute the code inside the click event based on the value on the isDragAndDrop -variable.

Before leaving the click event you the set isDragAndDrop = false

I found this solution on this link

    private void MyMouseDown(object sender, MouseEventArgs e)
    {
        if (e.Button == MouseButtons.Left && e.Clicks == 1)
        {
            Control source = (Control)sender;
            source.DoDragDrop(new MyWrapper(source), DragDropEffects.Move);
        }
    }
