Hi all -

I have a form with 3 radio buttons, representing 3 textboxes. The user =
will be required to enter a numeric value into 2 of the 3 textboxes to =
calculate the third textbox's numeric value. The selected radiobutton =
will represent the value the user is solving for. The textbox =
representing the missing value will need to be disabled. So, when rdoA =
is selected, txtA should be disabled, etc.

I'm having trouble with the change events of the radio buttons though. =
It seems that nothing is firing my CheckedChange event to run the =
necessary code.

The auto-generated sub that came from double-clicking the radiobutton =
control is:

Private Sub rdoMepForecast_CheckedChanged(ByVal sender As System.Object, =
ByVal e As System.EventArgs) Handles rdoMepForecast.CheckedChanged
End Sub

Any ideas? Thanks!!

I figured it out. :)

The AutoPostBack property for the radio buttons was not set to True.

It works like a gem.=20
