Hi NG,
in a dataset.datatab le I have rows, containing metric data as doubles.
I need to display/edit these values in textboxes depending on the culture
(Metric/Inch). Is there something like a built in conversion functionality
for that in the framework / visualstudio or do I have to do these
conversions manually?
Thanks for help and hints

As far as I know you would have to convert them manually.

Sure, but it's always nice to check first to make sure you're not
re-inventing the wheel.
No, there isn't, but there should be. Just as I was surprised to find
no framework support for loading currency conversion rates and doing
currency conversions. Not that MS could somehow provide the conversions
themselves, just some kind of standard way of loading and using them
would be nice.
Same with units of measure and unit conversions: it would be nice if MS
would just build them into the framework. Yes, they're dead simple and
100% internationally standard, but then how many people have written
them over and over again, all over the world? All the more reason to
toss them in the .NET Framework, IMHO.

Quite so.
Hi Rainer,
First of all, I would like to confirm my understanding of your issue. From
your description, I understand that you have a column containing data in
Metric data and you need to display and modify it in Metric/Inch accroding
to the user settings. If there is any misunderstandin g, please feel free to
let me know.
Generally, you need to do the conversion from Metric to Inch and backward
yourself. But if you only need to do the display, there is a simpler
solution. You can add another column with an expression to the current
DataTable. The new expression column counts from Metric to Inch with an
expression. For example:
ExpCol.Expressi on = "OrigCol/2.54";
Then bind certain textbox to the ExpCol to display the inch data. However,
the expression column is read-only and you cannot modify the value directly
in that column. If user changed the value in the textbox, count the value
for the OrigCol, and modify the OrigCol in DataTable and the ExpCol value
will change automatically.
HTH.

You caught my thought ;-)

You have my vote on that!

It's a pity. I am quit new to the framwork, but the functionallity I
experienced up to now is really great!
Thats why I was hoping, that this kind of "commonly needed" functinallity
would be in it. Well...
But if you only need to do the display, there is a simpler
solution. You can add another column with an expression to the current
DataTable. The new expression column counts from Metric to Inch with an

ExpCol.Expressi on = "OrigCol/2.54";
This is how I have done it in the meanwhile.

the expression column is read-only and you cannot modify the value
directly
in that column. If user changed the value in the textbox, count the value

Yes, I think this is how I will approach the issue.
Thanks

You're welcome, Rainer. Good luck! If you have anything unclear, please
