Hi.  I am using access 2010

I have a textbox  whose name is -------------- fltrStocknum
I have a routine   whose name is -------------- SetFilter

The user would type in a number in  fltrStocknum and then hit the <enter> key.  

When this happens,   I would like to call the SetFilter routine.   Also,  the focus must remain on the fltrStockNum textbox.

 I do not wish to pass the value of fltrStockNum as a parameter to SetFilter.  Instead,  the SetFilter routine should be able to read the fltrStockNum textbox directly.


I have tried following code,  but it doesn't work because the SetFilter routine reads the value of fltrStockNum as "" at that moment.

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
    If Screen.ActiveControl.Name = "fltrStocknum" Then
       If KeyCode = 13 Then SetFilter
    End If
End Sub


What is the best way to call the SetFilter routine when the user has hit the <enter> key.

<< SetFilter routine reads the value of fltrStockNum as "" >>

If fltrStocknum is currently in focus, you can use the Text property to get the data displayed in the box:

fltrStocknum.Text

Open in new window


See my article about Text vs Value here:

Well, you could put that in the AfterUpdate event of the textbox, but that would fire when they hit Enter, Tab, or click on some other control on your form.

Do you have the Forms "Key Preview" property (last property on the Event tab of the Properties dialog) set to Yes?

Hi,

Use the AfterUpdate event - then you know the data is what the user is searching for...

Keeping the focus on the control seems strange to me.  How would a user exit the text box?

Regards,

Bill

I would also advise you to use the vbKeyReturn keycode constant rather than the 13 to make it easier to read your code.

Thank you all.   The AfterUpdate event was all that I needed.
