I have this RadzenNumeric component:
<RadzenNumeric TValue="decimal?" Format="p" @bind-Value="@myValue"/>
When I input a value, say 23, it gets "formatted" to 2300,00 %.
Every time the value is changed, the result somehow gets multiplied by 100.
I would expect the formatted result to be 23,00% ( or at least 23%).
This should be easily reproducable on a fresh project.
Thanks for any help

In my opinion 0.23 is 23.00%:
Thanks for the quick reply!
Although I think it might be a bit confusing for the user, especially when trying to edit the value (when editing 56,00% to say 57,00%, the result gets multiplied - you need to write 0.57 again to get the correct result). But in my case it is alright as it is.
So, problem solved! 
You might need to check Mask components instead Numeric, might be more suitable for your expectations.
Hmm, I think maybe there is a misunderstanding of what's happening here?
If you make a RadzenNumeric input and it displays "30%", and you delete the 3 and replace it with a 4 so it instead says "40%", then it will suddenly change the "40%" to "4,000%" when you focus another element.
We face the same issue, we want our users to be able to type e.g. 30% instead of 0.30 since we display the percentages as xx% and not 0.xx.
You can check my last reply in this thread. Numeric component is for numbers that are formatted later using string format options provided by the .NET.
