如何设置comboBox的默认值？

Question

Hey i am making a comboBox that is holding a list of all the fonts name on my system, however at the beginning it does not hold any value and user needs to click on it to open it and select an item from the list. my question is how to set the default value for my comboBox (for example 'Arial') in case if nothing has been selected by the user and not to give error.

        foreach (FontFamily fnt in fonts.Families)
        {

            comboBox1.Items.Add(fnt.Name);

        }

Answer 1

You could search for a value such as "Arial" using FindString :

if (comboBox1.SelectedIndex == -1)
    comboBox1.SelectedIndex = comboBox1.FindString("Arial");

If you've got multiple entries starting with "Arial", the above will return the first match starting with Arial, so you may need to search for the exact string:

if (comboBox1.SelectedIndex == -1)
    comboBox1.SelectedIndex = comboBox1.FindStringExact("Arial Rounded MT");

Answer 2

You can just do:

comboBox1.SelectedValue = "Arial";

(assuming there is an element with value = Arial)
