RadzenNumeric<TValue> Class

RadzenNumeric<TValue>link

A numeric input component that allows users to enter numbers with optional increment/decrement buttons and value constraints. RadzenNumeric supports various numeric types, formatting, min/max validation, step increments, and culture-specific number display. Provides up/down arrow buttons for incrementing/decrementing the value by a specified step amount. Supports min/max constraints that are enforced during input and stepping, formatted value display using standard .NET format strings, and can be configured with or without the up/down buttons. Handles overflow protection and respects the numeric type's natural limits.
