DataCombo - ADO.NET

Can anyone tell me if there is a datacombo in .NET that has the same properties as the datacombo used with the ADODC in VB6.0? I was familiar with using the datacombo in 6 and wanted some of the properties in a datacombo with .NET. I would like to fill a datacombo box on form load and then as the user types into the box it will filter down to the exact record they are typing. I want to do it this way as it will prevent them from entering an incorrect number in the datacombo. The property I used was MatchEntry dblExtendedMatching. In .NET I have made a reference to 2 datacombos and I'm not sure which one to use. One is named AxDBCombo1 and the other is AxDataCombo1 (these are the control names not names I gave them). Can anyone tell me the difference and why I would want one over the other? Also if someone could give me a sample of how to code this. I'm assuming that I still need an ADODC but I'm not sure if there is something better to use in .NET.

Thanks,
Corinne
