How to configure ToolStripDropdownbutton size to match size of the parent dropdown button?

I am working on a C# desktop application. I am using a menu strips control in which I have used a开发者_开发百科 drop down button.

Whenever the dropdown is clicked, it displays items, but the Width of the Dropdown Menu seems to be the issue, it's always greater. I want it to be the same size at that of the button.

Here is a screenshot:

What I am struggling to configure:

1. I want the width of DropDown to be the same as that of button.
2. The arrow of the dropdown should be larger.
3. The button should be curvy, not flat styled, it's a ToolStripDropdownbutton.

Unfortunately you are going against the grain for this control, and you will need to resort to your own controls or custom painting to get exactly what you want.

You should be able to change the shape/size of the drop down arrow using custom painting. You should be able to restrict the size of the drop down menu by overriding the control. However as the drop down menu has space for ticks and shortcut strings I suspect you may need to do more work than you were expecting.

This suggests using the ToolStripControlHost(control) to host arbitrary controls. With a simple example at: http://alala666888.wordpress.com/2010/07/15/custom-toolstripitem/

You could possibly use a ComboBox control instead and change the DropDownStyle to DropDownList.
