The RadzenNumeric control uses a string parameter as the step size. If I try the samples in my machine, they don't work properly as the Step parameter has a dot but in my machine it expects a comma as decimal separator (es-ES culture). Why the Step parameter is not of type "TItem" ?
Also, it seems that the control size depends on the Step, Max an Min parameters. However, it does not work for my culture. If I specify a Step="0,001", Min=0 and Max=40 the control does not display all the digits. I need to specify a Step="0.001" for it to make the control wide enough. However, as my culture is es-ES, it increments the value in steps of one instead of 0.001 because of the problem described in the first paragraph.
And last but not least, that automatic sizing can be useful in a lot of scenarios, but it would be great if there is a parameter to turn it off in order to have consistency in width sizes between different RadzenNumeric components.
