What is the best way to take text entered into a texbox and populate a dropdown list from the primary key of the the textbox value?

I dont totally understand your question - could you clarify? What do you mean by "from the primary key of the the textbox value"?

I have a textbox where a style is going to be put into. Once the style has been put in the textbox the user then selects the submit button and the "styleid" from the style table will be used to populate a dropdown list for all style/color/sizes that have that "styleid".

I need the easiest way to do this. Thanks in advance!
