Hi everybody,

Im looking for a solution for my problem:

I want a simple text field in de contact entity, with a minimum AND Maximum characters lenght of 5.

now it is possible to specify a maximum. but not to indicate a minimum. The format of the form must be (days / months). So from 01-01 to 31-12. Preferably with the first two values that can go up to 31 and the last two values to 12. But just a minimum would solve a large part of the problem.

I understood that this might be possible through javascript in the onchange event?

If this is not recommended because it is too much work, then I would also like to hear that.

Regards,
Daimy Tamis

Hi,

I think you can create Javascript and put onchange event on that attribute. Then you can use Regex or just use traditional way (split by '/', parseToInt to check if the value is int or not and check the length <= 5 or not).

Is not to difficult and you can handle it using Javascript.

Hi Daimy Tamis,

It can be done with On Change JavaScript. The rough process for creating the JavaScript is as follows.

Create a JavaScript file that runs On Change of your simple text field.

With the JavaScript code, retrieve the value of your simple text field, check its length, and prevent save of the field if it does not contain five or more characters.

This is a basic example of a JavaScript function that can accomplish this.

function FieldValidation(context) { var field = Xrm.Page.getAttribute("field").getValue(); if(field.length < 5) { Xrm.Utility.alertDialog("Please enter five or more characters in field"); context.getEventArgs().preventDefault(); } }

However, it sounds like you are working with date values. Consider creating a Date and Time field before trying to solve this problem with JavaScript.

Hi Daimy ,

I understand your problem , but unfortunately there is no way to define your specific business logic without code. You need to write JS code for that ,there is no other options .
