I\'m writing a Windows Forms app in C#, using Visual Studio 2010.
It has a combo box. I\'ve set the DropDownStyle to \"DropDownList\", and added a few lines to \"Items\
I'm not sure if this is what your asking for but if you want a specific item to be set as default I.E you load the form and there is already a value selected for you.
Simply put this into your public Form1()
method.
comboBox1.SelectedItem = "Test1";
//comboBox1 change to the name of
//your combobox
//Test1 change to the item in your list of items that you want
//defaulted.
I think that is by far the best way to do it.
