Combo BOX with condtions?

Hello there Guys, I would like your claims.

I am interested in the file format or some sort of tutorial of learning to make a multiple combo box with affliction.
As an example:Let’s point out I’m likely to have A FEW combo cardboard boxes, and every one of them will work as outlined by the previous collection of previous combo box.For instance, if WE select condition Illinois from your first combo box, your second combo package will show only your cities involving Illinois (Chicago, along with etc…).

There has to be a distinct extension or even any advises will help
thank an individual guys

There is definitely no straightforward way to achieve this, unless you will find some wording files listing all of the cities in each say, as very well as text message files for your data you will have in the next combo field.If that’s available, you could potentially add these text files in your application (computer).Then while you clicked in Illinois, you can open your Illinois town text archive and insight this facts one city back then and create a savings fund ComboBox2.Goods.Add(City).The identical would utilize when populating thirdly combo package.

When you wanted to feature only minimal states plus cities and also other data, you generate your text documents (or databases) to complete the same thing.A lengthy and wearisome task with the least.
