behavior difference between clicking a radbutton and hitting enter when selected

[Casey]

I have an issue that I have been going around in circles with for a little while now. I have a webform with a simple save button on it

<telerik:RadButton ID="btnSaveProduct" runat="server" Skin="Web20" Text="Save"></telerik:RadButton>

which has code for the click event

Private Sub btnSaveProduct_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSaveProduct.Click
If pageIsValid() = True Then
processPage()
End If
End Sub

I am running into a problem because when the user clicks on the button the btnSaveProduct_Click event is fired correctly and everything on the form is saved correctly. However, when the user tabs over to the button and clicks enter the btnSaveProduct_Click event is fired correctly but the items on the form are not saved correctly. It hits all the same code and the only difference is how the user clicks save. It almost seems like the clicking the button does a postback to the form but tabbing and clicking enter does not.

Does anyone have any insight to what the problem may be??

Nevermind. I replaced some of the controls on the grid with telerik controls and that did the trick. I think the old contols didn't like ajax.
