Are there any other options for SearchMode in the WinComboBox? We're trying to allow a softseek/drilldown functionality where they start typing and it gets closer and closer to the value. Imagine this scenario.

You have these 4 numbers in the list

100
120
200
220

If I start typing a 1 it should highlight 100, if I then typed a 2 it will highlight 120. But if I typed a 3 instead it would unhighlight everything. When we're dealing with thousands of very similar numbers the first character seek just isn't good enough.

Let me know if you guys have any ideas.

Thanks,

Nathan

You will need to use a custom auto-complete source to do this.  Adding to your example, you can do something like the following : 

AutoCompleteStringCollection coll = new AutoCompleteStringCollection();

coll.AddRange( new string[] { "100", "120", "200", " 220" } );

winComboBox1.TextBoxArea.AutoCompleteMode = AutoCompleteMode.Append;

//or, depending on how you want to display the suggested items, you can use the following instead

winComboBox1.TextBoxArea.AutoCompleteMode = AutoCompleteMode.SuggestAppend;

winComboBox1.TextBoxArea.AutoCompleteSource = AutoCompleteSource.CustomSource;
