Introduction

I needed to drop a custom control when the comboBox button is pressed, so i adapt the comboBox to drop what i want. This article explain how to make a standard ComboBox to drop a custom control. You can use that method to drop a dataGridView in a datagridview if you need. I need to override the WndProc method of the ComboBox to stop the ComboBox to display the standard list.When the comboBox button is pressed, the message is captured and canceled and is shown a ToolStripDropDown control that contain the custom control. The custom control is dropped as a ToolStripDropDown, so we need a ToolStripControlHost to host the control that we want to drop. Have fun!
