It would be so good if its size changes according to which design properties are set.
The RadzenNumeric's inside the RadzenDatePicker could also have the same height of other RadzenNumeric's.
I don't know why this component has been used to both Dates and Times, but it could get messy in the future according to the amount of configurations. Telerik has separate components for each type, and some sort of Date/Time range components. If these are planned to be added in the future in Radzen, then again, better make individual components.
Everything in the Radzen component suite can be customized via CSS.
Not sure what's the issue here. What could get messy? You can always use two Radzen numeric components side by side if you don't like the appearance or the default RadzenDatePicker or tweak the CSS to your preference.
You are free to use components from any vendor! Radzen however provides design time support only for Radzen components.
I need some extra help on this one. After tweaking lots of things in the .css class, there's one thing that I can't change, which is the component's width. Here's how it's set:
I need to change that 320px width, but I don't know how.
