I want a ZIP form field and when the user start to type it and it length reaches 4 length the code automatically get its city name from database.
Constraints:
only digits,
max 4 digits and the field noesn't allow more.
I tried RadzenNumeric field but it allows more digits than what is set in Max property and after changing the focus from field evaluates its chack.
I tried RadzenTextBox but I cannot disallov letters in it.
I tried RadzenMask but the @oninput eventhandler doesn't work. It doesn't call the eventhandler method.
