how to set dropdownlist height and how to show dropdownlist's list always downward display

How can I set a dropdownlist control's height in C#?

I tried this, but it doesn't work:

cbo.A开发者_如何学Cttributes.Add("style", "height: 50%");  

And, how can I make sure a dropdownlist's list is always dropped down rather than up?

At last I got it..

 cbo.Height = new Unit("250px");

I can set dropdownlist height with above code.

Temporarily you can increase the font size of the items in the dropdown control, this will set height. Will try to find a better solution.

The answer to "How to set height" is:

   cbo.Height = new Unit("250px");

You can set the height of a dropdownlist as follows:

combobox1.DropDownHeight = 106;

Make sure that the DrawMode attribute of the combobox is set to Normal. This way it's items can be populated without much difficulty.
