Hi,

We're using numeric textboxes in a grid that allows for keyboard navigation.  The problem is that the up/down arrows still increase and decrease the values in the textbox before the navigation event occurs.  Is there a way to disable the default key events, or modify them?

Thanks,
Kevin

Hello Kevin,

I am afraid that is not very clear what "navigation" event occurs when value of NumericTextBox is increased/decreased. Could you elaborate more on this requirement?

In general, widget's keyboard navigation is enabled by default and cannot be prevented nor modified. If you need to change widget behavior, then you will need to override its current implementation.

Hi George,

To elaborate, we've designed a grid so that when the user presses the arrow keys it shifts focus to the control in that direction.  So the up arrow key moves the focus to the element in the row above, and down arrow sets the focus on the element in the row below.  

This is working but it's also increasing or decreasing the value in the NumericTextBox at the same time.  I was hoping to find out how to disable this increment/decrement behaviour on keypress.

Thanks,
Kevin

Hello Kevin,

The only way to disable the increment/decrement behavior is to unbind current "keydown" event handler. Here is a Dojo demo that demonstrates one possible implementation.
