Hi Afshin,
Thanks for the update.
We would like to inform that, in our current implementation the SfDigitalGauge’s Value is rendered from the starting position of the control and its width is depends on CharacterWidth, CharacterSpacing properties, not based on control width. So, we can’t stretch the SfDigitalGauge content based on the control width. We suggest using control height and character height property to position the SfDigitalGauge content at the center.
Regards,
Eswaran
