Access command button

FormB displays records whose source is QueryA.
QueryA returns the following records sorted alphabetically on Field1:

Action
Add
After
Age
Back
Before
Build
Call
Clear

I have created command buttons on FormB captioned A,B,C,...one command button for each letter in alphabet.
How can I trigger an event so that when a command button is pressed (example: B), only records beginning with the letter "B" in Field1 are displayed in FormB?  Subsequently, I will want to press another command button, clear the form and display only those records where Field1 records begin with the letter corresponding with the caption of the command button pressed.

Well, if you are going to do this with buttons, your best bet would be to create a single button, and set the caption property of that button to "A", and the property of the Click event of the button to:  =fnFilterForm()

Then you create a function in the forms code module that looks like:

Private Function fnFilterForm()

    Dim strFilter as string

     strFilter = "[Field1] LIKE '" & screen.activecontrol.Caption & "*'"
     me.filter = strFilter
     me.filterOn = true

End Function

Open in new window

Then you would copy that command button, once for each letter of the alphabet, and simply change the caption from "A" to the appropriate letter.

But personally, I prefer to either use a combo box, or a textbox to save screen realestate.  For a combo box, I would set the RowSourceType to ValueList (although I rarely do this), and set the RowSource to: A;B;C;D;E;...;Z.  Then I would use the combo boxes AfterUpdate event:
Private Sub cbo_Filter()

    Dim strFilter as string

     strFilter = "[Field1] LIKE '" & me.cbo_Filter & "*'"
     me.filter = strFilter
     me.filterOn = true

End Sub

Open in new window

When I need more flexability than filtering on just the first letter, generally add a textbox (txt_Filter) and a command button (cmd_Filter).  I then use the cmd_Filter_Click event

Private sub cmd_Filter_Click()

    Dim strFilter as string

     if me.txt_Filter & "" = "" then
        me.FilterOn = false
     Else
          strFilter = "[Field1] LIKE '" & me.txt_Filter & "*'"
          me.filter = strFilter
          me.filterOn = true
     end if

End Sub

You also need to put the function in FormB's code module, not in a shared (standard) code module.
