Question

I can’t solve this problem. I need to populate comboBox items from values in listBox (Windows Form in C#).
Every time I add values ​​in listbox, combobox automatically has to be populated.

Thanks in advance.

this is code, but now working

for (int i = 0; i < listBox1.Items.Count; i++)
        {
            comboBox1.Items.Add(listBox1.Items[i]);
        }

Answer 1

private BindingList<string> bindingList;

List<string> stringList = new List<string();
//populate the list any way you want for example
stringList.Add("Hello");
stringList.Add("Good Morning");

bindingList = new BindingList<string>(stringList);
this.comboBox1.DataSource = bindingList;
this.listBox1.DataSource = bindingList;

I would suggest loading the strngList variable using a loop or if the data is coming from a database load the fields that way then Bind to the ComboBox.
