    I have a numeric textbox inside a Grid. I would like to allow showing a "," as a separator (thousands) and also allow decimals.

    In the OnEdit of the Grid, I have the following setup:

    1.edit: function(e) {
    2.                e.container.find("input[name^=costOperand]").kendoNumericTextBox({
    3.                    min: 1,
    4.                    max: 888888887,
    5.                    step: 100
    6.                });


    With the above the numeric textbox doesn't allow me to type in a ",". Only decimals are allowed.

    Any idea?

    In general the NumericTextBox operates in two modes - display and edit. While in edit mode it allows to type in only numbers, "-" and decimals operator(which is defined by the current culture). Once the widget is in display mode(on blur) it will format the entry based on the culture and format configuration.  

    Please refer to this example. If 10000 is entered and the current culture is "en-US" the number will be displayed as 10,000.00

    I've got a requirement to implement this as well - they would like to see "12,345,678" during edit mode as well as display.

    Hi, Simon,

    I can see that you have also submitted a private support thread asking the same question.

    I will paste the response here for future reference, in case you have further questions, please let us resolve them privately and then we can update this public forum.


    When in edit mode the numeric displays the actual number value (js number) - not a string. Thus, it is not possible to format it.

    However, you could achieve the described behavior by handling the input event handler of an input element.


    function formatValue(e){
        var value = $(;
        var number = parseFloat(value.replace(/,/g, ''));
        var newValue = isNaN(number) ? 0 : number;                  

    Below you will find a small sample which demonstrates the above approach:
