Binding Combobox Using Dictionary as the Datasource

Question

I'm using .NET 2.0 and I'm trying to bind a combobox's Datasource to a sorted dictionary.

So the error I'm getting is "DataMember property 'Key' cannot be found on the Datasource".

        SortedDictionary<string, int> userCache = UserCache.getSortedUserValueCache();         userListComboBox.DataSource = new BindingSource(userCache, "Key"); //This line is causing the error         userListComboBox.DisplayMember = "Key";         userListComboBox.ValueMember = "Value"; 

Answer 1

SortedDictionary<string, int> userCache = new SortedDictionary<string, int> {   {"a", 1},   {"b", 2},   {"c", 3} }; comboBox1.DataSource = new BindingSource(userCache, null); comboBox1.DisplayMember = "Key"; comboBox1.ValueMember = "Value"; 

But why are you setting the ValueMember to "Value", shouldn't it be bound to "Key" (and DisplayMember to "Value" as well)?
