Posted on by BluFin.S

Hello,

Can anybody tell me what is the alternative for Input Mask custom control to use in forms of model-driven apps? As the control is retired so need to know the alternative.
I need to specifically edit the module Lead on Microsoft Dynamics 365 Sales adding a field with this formatting number "00.00.00"

I've spent 2 evening without find the solution, can u please help me step by step?

Thank you in advance

PS:
Asked also to copilot but i did not understood how use "concatenate" :)

Hi

I am a dorko maybe, but I do not understand how the first 2 sentences are related.

Are you saying you want to create a Calculated (Formula Column) that takes the value from one of your columns and makes it look like 00.00.00

If so thats what it meant by concatenate. However I would need to see the actual DATA (at least a few rows, even if fake) of what the field has in it

so I can tell you the formula to type in.

Use Regular Expression for Input Formatting: Since the Input Mask custom control has been retired, you can use Regular Expressions (RegEx) to enforce input formatting, like "00.00.00," using JavaScript on the form.

Create a Custom Field for the Lead Entity: Go to Power Apps > Solutions > Select your Dynamics 365 Sales Solution. Add a new text field to the Lead entity to hold the formatted number.

Add JavaScript to Enforce the Format:

function formatInputNumber(executionContext) {
var formContext = executionContext.getFormContext();
var numberField = formContext.getAttribute("new_numberfield").getValue();

if (numberField && !/^\d{2}\.\d{2}\.\d{2}$/.test(numberField)) {
// Format the number (you can customize this to your needs)
formContext.getAttribute("new_numberfield").setValue(
numberField.replace(/(\d{2})(\d{2})(\d{2})/, "$1.$2.$3")
);
}
}

Attach JavaScript to the Lead Form: Set the JavaScript function (formatInputNumber) to trigger on the "OnChange" event of the new field.

@SaiRT14 thank you very much for your help btu something doesn't work, i have also tweaked the script with the correct field name for "Codice ATECO/NAC" that is "sic"

Can you help me troubleshooting it?

Here's the code:

function formatInputNumber(executionContext) {
var formContext = executionContext.getFormContext();
var numberField = formContext.getAttribute("sic").getValue();

if (numberField && !/^\d{2}\.\d{2}\.\d{2}$/.test(numberField)) {
// Format the number (you can customize this to your needs)
formContext.getAttribute("sic").setValue(
numberField.replace(/(\d{2})(\d{2})(\d{2})/, "$1.$2.$3")
);
}
}

Thanks SaiRT14 you have pointed me, the right direction, and finally i have fixed the script this way:

function formatSICField(executionContext) {
var formContext = executionContext.getFormContext();
var sicField = formContext.getAttribute("sic").getValue();

if (sicField && sicField.length === 6) {
var formattedSIC = sicField.replace(/(\d{2})(\d{2})(\d{2})/, "$1.$2.$3");
formContext.getAttribute("sic").setValue(formattedSIC);
}
}

function validateSICField(executionContext) {
var formContext = executionContext.getFormContext();
var sicField = formContext.getAttribute("sic").getValue();
var regex = /^\d{2}\.\d{2}\.\d{2}$/;

if (sicField && !regex.test(sicField)) {
formContext.getControl("sic").setNotification("Invalid format. Please use the format 00.00.00.");
} else {
formContext.getControl("sic").clearNotification();
}
}
