How to get Regular Expression in IgGrid cell (Infragistics)?

Question

how can i have a regular expression on a igTextEditor in igGrid Updating?

i tried to use validate option but it didn\'t worked.

   $(\"#schedulerTable\")         


        

Answer 1

The lack of validation is because the validatorOptions belong to the editorOptions (as those get passed down to whatever editor you choose as provider). The validation: true only gets some defaults, which really won't do much for a text field besides the required.

And then the RegExp option (which is for an email in the snippet above as far as I can tell) has been pattern since 15.2 :) So in the end for that time column you can try:

//...
    editorOptions: {
     validatorOptions: {
       pattern: /^\d{1,2}\:\d{2}$/,
       onblur: true,
       onchange: true
     },
    },
//..

Here's an updated codepen: https://codepen.io/anon/pen/YrgYxj

Edit: Or if you want to set the error message:

//...
    editorOptions: {
     validatorOptions: {
       pattern: {
        expression: /^\d{1,2}\:\d{2}$/,
        errorMessage: "Time should match a pattern like 00:00"
       },
       onblur: true,
       onchange: true
     },
    },
//..

Depending on your goals you could also use a Mask Editor or a Date Editor as provider. Also the obligatory docs link: https://www.igniteui.com/help/iggrid-updating

P.S. Bind to an empty array to avoid the error for that first row that has no values and more importantly primary key.
