I am trying to use this unsuccessfully with a combobox. I noticed a thread that mentioned not having more than 1 column but I'm assuming this does not include specifying 2 fields in order to use the boundto property for the PK. I have a combobox which specifies fields as the type with the field list being a name, primary key. I have the boundto set to 2. However, I have not specified wanting multiple columns because I only want to display the name. Can anyone help me with getting itemtips to work? Even when taking out the multiple columns it doesn't seem to work so I feel like I'm missing the setup of another setting.
