JavaScript Grid column - patternMask Config

Optional. Sets an input mask for entering number and string values according to a special pattern

patternMask?:
    | {
        pattern: ((value: string | number) => string) | string,
        charFormat?: {
            [char: string]: RegExp
        }
      }
    | string,

The patternMask property can be set in two ways:

• as an object with the following properties:
  • pattern - (function | string) allows specifying the necessary mask and change it dynamically, depending on the entered values. Can be set as:
    • a function that takes as a parameter an entered value specified as a string or as a number and returns a string with a pattern mask
    • a string with a pattern mask
  • charFormat - (object) allows specifying a regular expression for an optional symbol. It is set as an object with key:value pairs, where the key is a symbol and the value is a regular expression
• as a string allows setting a mask as a string using a predefined set of symbols

const grid = new dhx.Grid("grid_container", {
    columns: [
        {  
            id: "employee_id", 
            header: [{ text: "Employee ID" }], 
            patternMask: "ID.000" 
        },
        // more columns configuration objects
    ],
    // more options
});
