C＃捕获鼠标右键单击ToolStrip下拉项目中单击

Question

I want to capture the right click mouse event within the ToolStripDropDownItemClicked Event

private void toolStripDropDownButton1_DropDownItemClicked(object sender, ToolStripItemClickedEventArgs e)

Based on the right click, i display a contextmenu. So, I need to get both the item clicked and mouse click right.

You could use the MouseUp or MouseDown event it knows which button was pressed. The sender object is the menu item that was clicked. Cast it to the correct type to access it's properties. If you're not sure about the type you could use as and then check if the resulting object is null.

void firstToolStripMenuItem_MouseUp(object sender, MouseEventArgs e)
{
    var toolStripMenuItem = (ToolStripMenuItem)sender;
    var nullIfOtherType = sender as ToolStripMenuItem;
    var right = e.Button == System.Windows.Forms.MouseButtons.Right;
}

How to get a right click mouse event? Changing EventArgs to MouseEventArgs causes an error in Form1Designer?
