Decimal precision to significant digit in UI for WPF NumericUpDown

Hi,

We develop engineering software tools which means we must support values to varying degrees of accuracy.

For input from the user we are using the RadNumericUpDown control and set the NumberOfDecimalDigits property to the required precision. This works great however, for example if we set the precision to 10dp, the control displays 0.000000000 for a value of "0".

How can we change the control to display the value up the the significant digit rather than the maximum precision specified on the control?

To further clarify:

with a max of 10dp precision allowed if the user enters "1.1234" the value in the text box is 1.1234000000. However the user just wants to see 1.1234 without the trailing zeros.

Hi Simon,

I am afraid that this is not possible with the current implementation of the control. If we receive more clients' requests we will consider implementing a way to remove the unnecessary digits.
Sorry for the caused inconvenience.

All the best,

Hi.

This would be a greate feature.
Currently we switched to the "Extended WPF Toolkit" from Codeplex if we need a NumericUpDown.
It is free and supports the requested behaviour.

Thanks for your reply J.S

Yeah we have switched over to the DoubleUpDown which we are now using which has the desired affect. They also have a DecimalUpDown and IntegerUpDown.

I would also like to see this feature implemented. Our software are dealing with generic environments where the required precision is not known beforehand. Currently we have to set the digits to a high value just in case customer needs it, but it look really bad if the actual value doesn't require so many digits.

I would like to see an option to trim the trailing zeros on display, or an option to turn off decimal place enforcement on data binding (i.e. user can still manually enter 1.23456 when NumberOfDecimalDigits=2, and it will not be changed to 1.23 quietly)
.

Hi,

As we see this is an feature request that you would like to see implemented in the control we have logged it in our Public Issue Tracker system. You can find it here where you can vote and track its status.

If it gets enough votes we will consider implementing it as a built-in feature in the control.

Hi Russell,

The HideTrailingZeros property of RadNumericUpDown has been introduced with the Q3 2013 SP1 Release version. More information on it you can find here:

http://docs.telerik.com/devtools/wpf/controls/radnumericupdown/features/formatting.html#hide-trailing-zeros

Hope this helps.
