Hi,

Did you look at using the Binding Parse and Format events to handle the conversion ?
If you're using the Binding class that should be a much cleaner implementation.

>I was overlooking the obvious that day. :o) The problem was with our default classes in the other layers. I had to create a special base textbox to control the saving. We have base classes but the base textbox classes already created only passed 'TRUE' and 'FALSE' based on a value of 'TRUE' or 'FALSE.' I had to create a new special basetextbox class to look for 'Y' and 'N,' but pass 'TRUE' or 'FALSE' to the business layer and then on to the other layers respectively...

One way was using the passwordchr and setting maxlength to 1, another was the example below, another used a bool value and converted it to string before sending it to the business layer, and the other was a different way of doing what is done below.

I have that working using the keypress event. I am also changing the value in the _TextChanged() so that when data is first loaded, it displays Y instead of TRUE and N instead of FALSE. Both of those work fine.
