c# winform get all rows from one column into dictionary and bind to list?

hi all my code below should hopefully explain where im trying to get to if someone could point out the errors and put me in the right direction?

i want all the rows from the column Trades in the Trades Table and get them in a dictionary and bind them

Thanks

Dictionary<string, string> dictATrades = new Dictionary<string, string>();
            foreach (DataRow trade in dataSetMisc.Trades.Rows)
            {
                dictATrades.Add((string)(trade["Trades"]), (string)(trade["Trades"]));
            }
            var dictATradesSort = (from entry in dictATrades orderby entry.Value ascending select entry);

            lstAvailbleTrades.DataSource = new BindingSource(dictATradesSort, null);
            lstAvailbleTrades.DisplayMember = "Value";
            lstAvailbleTrades.ValueMember = "key";
