How to prevent ListBox.SelectedIndexChanged event?

Question

I am using a listbox in my C#2.0 windows forms application. The method to populate the list box is

    private void PopulateListBox(ListBox lb, ReportColum         


        

Answer 1

private void PopulateListBox(ListBox lb, ReportColumnList reportColumnList)
{

    lb.SelectedIndexChanged -= this.*MethodnamewhichhandlesthisEvent*;  //unset eventhandler

    lb.DataSource = reportColumnList.ReportColumns;
    lb.DisplayMember = "ColumnName";
    lb.ValueMember = "ColumnName";

    lb.SelectedIndexChanged += this.*MethodnamewhichhandlesthisEvent*;  //set the eventhandler
}

Basically remove the delegate from the event and then add once you are done.
