DataGridViewCom boBox problem

4 New Member
I have a datagridview with two comboboxcolumns . I want the combobox in column B to be dynamically filled with data from the database depending on which item is selected in column A. How do I go about this?

Thanks for your help. I am not a novice, but I am certainly not a master.

I think comboboxcolumn B has to be an unbound column then, and you need to create a query based on the state of box A?

I am confused though, if both sets of data come from a database, why not just make your initial query return the correct values?

Each row may contain something different in col a, which would generate something different in col b.

For example, column a for some rows will contain subsidiary detail, but other rows, no. Does that make sense?
