Newbie Question: Using Combo Boxes to Filter Data

Zones: Access Forms, Databases Miscellaneous, Microsoft Access Database

Tags: Microsoft, Access, 2007, Combo Box

Hello experts

I'm sure this is the simplest question ever, but I'm short on time so here it goes:

I have a table of information on teachers (Name, school, and notes). I want to have a form with a combo box on it that lets me choose a school and automatically list all the teachers at that school in a control on the same form. What's the quickest way for me to do this, or is there another (quicker) method of accomplishing the same thing?

Thanks.

Set the Rowsource property of the Teachers combo to:

SELECT [Name] FROM tblTeachers WHERE School = [cboYourSchoolComboName]

and in the after update event of the schools combo box

Me.cboTeachers.Requery

Main form with a subform will work great for this. When you add the subform to the main form just link the school for the main and subforms. You only need to put the school combobox on the main form.

bussd:

Sorry... I should have mentioned that the combo box populates correctly (i.e. it contains a list of schools). I just need to display a list of teachers at the school specified in the combo.

So you want to populate combobox 2 from combobox1?

Saugerties Miller
Saugerties Smith
Kingston Doe

So if you select Saugerties combobox2 will only show Miller and Smith?

Capricorn: Thanks... I'm looking at the sample but it will take a little time for me to figure it out.

Wiswalld: I only want one combo box. Ideally it would populate a grid with the info for all the teachers at the school.

I'll try to illustrate...

combo box (list of schools)

Teacher info:
NAME NOTES
-----------------------------------
Joe Smith Mon - Fri
Jane White Tuesdays and Thursdays
Sam Jones Mon - Fri

Hopefully that helps...

Create a form in design view. Base the form on your table. Add the one field you want as a combobox. Drag a subform onto the form based on the same table. When prompted link the two fields. Walla

wiswalld: when you say "drag a subform onto the form..." do you mean I should create two forms and drag one onto the other, making it a subform? I haven't worked with subforms before...

01.15.2008 at 11:21AM PST, ID: 20665554

bussd:

Sonchoy: thanks but I don't want the teacher data displayed in a combo box. I'd like it displayed in a tabular format (I think it was called a data grid in VB, but it's been a long time since I worked with that...)

In the toolbox select subform/subreport and create one on your form which will in turn create a new form.

OK I came up with what I think will work better for you.

First I created two tables. One with all my information and one just for the school names

Next I created a form in design view and added a combobox and based it on the table with just the school in it. Then I added the subform based on my table with evertything. I went to the combobox and in the on change event put this

Me.[Table1subform].Form.Filter = "[school]='" & Me.Combo0 & "'"
Me.[Table1subform].Form.FilterOn = True

I'm using Access 2007 and I don't see anything on the ribbon called subform or subreport. I can create a "split form", but I don't think that's the same thing. In the help it says I can create a subform either using the form wizard or by dragging one form on to another.

Thanks everyone for all the information... I'm going to take some time to sort through it and see if I can get my app to work. I'll assign points when it's working...
