C# Update combobox bound to generic list

Question

I have a combobox on my form that is bound to a generic list of string like this:

private List mAllianceList = new List();

priva         


        

Answer 1

The easiest way around this would be to simply use a BindingList like so:

private List<string> mAllianceList = new List<string>();
private BindingList<string> bindingList;    

private void FillAllianceList()
{
    // Add alliance name to member alliance list
    foreach (Village alliance in alliances)
    {
        mAllianceList.Add(alliance.AllianceName);
    }

    bindingList = new BindingList<string>(mAllianceList);

    // Bind alliance combobox to alliance list
    this.cboAlliances.DataSource = bindingList;
}

Then, from here on out, just deal with the binding list to add and remove items from there. That will remove it both from the List and from the ComboBox.

EDIT: To answer your question regarding sorting, I guess the easiest (but possibly "hacky" way to do it would be something like this:

mAllianceList.Sort();
bindingList = new BindingList<string>(mAllianceList);
this.cboAlliances.DataSource = bindingList;

So basically, after you sort, you create a new binding list and reset the data source. Maybe there's a more elegant way to go about this, however this should work.
