بسم الله الر حمن الر حيم

          How to add item on comboBox in C#? Please follow me:

1. Add component of comboBox in Form
2. Double click header of Form
3. Type below text (if your comboBox name is comboBox1)

comboBox1.Items.AddRange(new object[] { "String1", "String2", "String3", "String4", "String5" });

comboBox1.Text = "String1";

Or, you can add one of string to your comboBox:

comboBox1.Items.Add("http://alfatikhul.blogspot.com");

Or, you can load from other component, maybe richTextBox?:

comboBox1.DataSource = richTextBox1.Lines;

To remove one item of list:

// To remove item with index 0:

comboBox1.Items.RemoveAt(0);

// To remove currently selected item:

comboBox1.Items.Remove(comboBox1.SelectedItem);

// To remove "http://alfatikhul.blogspot.com" item:

comboBox1.Items.Remove("http://alfatikhul.blogspot.com");

To remove all item on list, use:

listBox1.Items.Clear();
