Question

I have a combobox with objects of Foo type, here is the Foo class:

public class Foo
{
    public string name { get; set; }
    public string path { get; set; }
}

The Foo.name is the displayed text in the combobox and Foo.path is the value of the selected option.

I want to delete an option from the combobox after some operation I made.

I’ve tried these ways:

• 1

  comboBox2.Items.Remove(@comboBox2.Text);  
  

• 2

  comboBox2.Items.Remove(@comboBox2.SelectedValue.ToString());  
  

• 3

  Foo ToDelete = new Foo();
  ToDelete.name = @comboBox2.Text;
  ToDelete.path = @comboBox2.SelectedValue.ToString();
  comboBox2.Items.Remove(ToDelete); 
  

Nothing works for me. : / How to do this?

UPDATE

This is how I’m initializing my combobox:

    string[] filePaths = Directory.GetFiles(sites.paths[comboBox1.SelectedIndex]);

        List<Foo> combo2data = new List<Foo>();

        foreach (string s in filePaths)
        {
            Foo fileInsert = new Foo();
            fileInsert.path = s;
            fileInsert.name = Path.GetFileName(s);
            combo2data.Add(fileInsert);
        }

        comboBox2.DataSource = combo2data;
        comboBox2.ValueMember = "path";
        comboBox2.DisplayMember = "name";

Answer 1

comboBox2.Items.Remove(comboBox2.SelectedValue); will only remove from the combobox, not from the datasource bound to the combobox. You may remove it from the datasource and re-bind the datasource.
