I just went through something like this today.

VFP would not allow the dragging and dropping of a custom control from the Classes tab of the Project Manager. There were two workarounds for this:

1. Click on the View Classes button of the FOrm Controls toolbar. Select Add and select the class library for your control. From the Properties sheet, select the appropriate column from the dropdown. Click on the Combo class in the toolbar and click on the Form Designer titlebar (not anywhere in the form). Then click within the appropriate column. It worked here.

2. The other way involved dragging the control from the Project Manager to somewhere on the form. Select the control, CTRL-X to cut it into the clipboard and then select the column from the Properties sheet. Click on the Form Designer titlebar and CTRL+V to paste it in. This also worked.

HTH.

In other words, I downloaded it from files section. It is a searchable combo. For example, the combobox has control source is product name(of product table). There are so many product names, and the users don't remember the whole name(if it's too long), they just type the first character, then the whole name shows up.
