    Is their currently a way to specify either inputmode="decimal" or pattern="\d*" so that an iPhone will present a user with a number only keyboard with a decimal in the case of inputmode="decimal" or a number only keyboard without the decimal key in the case of pattern="\d*"?


    Currently if I try to add it directly in to the HTML I get an InvalidOperationExecption specifying that the TelerikNumericTextBox does not have a property matching the name 'inputmode'.

    Hello Larry,

    At the moment, you can use a "regular" input where you can add such attributes, and style it like ours:

    In the meantime you can also try our numeric textbox that limits the input too (even if the user writes letters, there is an indication they are not allowed):

    Components (such as ours or any component you make in your app) will throw such exceptions when a parameter is used that is not implemented. There are two solutions to this:

    • implementing the parameter in question
    • implementing attribute splatting

    You can Follow the implementation of additional attributes or attribute splatting for the Telerik textbox in these pages (at this point I don't know if attribute splatting will be implemented, or explicit parameters):

    I also logged here an enhancement idea that the NumericTextBox we have should render type=number to guide mobile devices for the proper keyboard type, so you can Follow it too:

    I must also note that a keyboard for a mobile device must be accompanied by proper validation on the server, because a user can always tamper with the input, and desktop users with physical keyboards do not benefit from customized virtual layouts. So, you may want to add a data annotation validation anyway, or use our numeric textbox that does not accept anything but numbers.

    Thank you for the suggestions.  It is not the end of the world if the functionality is not there but it just makes for a nicer end user experience on a mobile device.
