Random Integer Value in PartialView Macro
Hi,

I have a macro, that renders a contact formular. If the user insert the macro several times on the page, I want to give each macro a unique id for their input-fields, so that my javascript code know which input-field to check.

I thought this would be very easy:
```
@{   
Random rnd = new Random();
   string rndInt = rnd.Next(5000, 10000).ToString();

}
<div class="agent-form">
    <form role="form" id="form-contact-agent_@rndInt" method="post" class="clearfix">

    ...

    <input type="text" class="form-control" id="name_@rndInt" name="name_@rndInt" required="">
    ...

    </form>
</div>
```
I put two macros per Grid-Insert Macro Selector on the page. Both macros render with the same random Integer. Cache for the macro is not activated of course.

So did I do something wrong or is it an umbraco-performance issue, that same macro-source is only rendered once?

OK, Why don't you create a helper class to handle this. Something like this:
```
Random rnd = new Random((int)DateTime.Now.Ticks);
int RandomNumber;
RandomNumber = rnd.Next(100000, 999999);
```
and call it from your view

Hi Streety,

thanks for the hint.

This one does the trick:

@functions
{
    public int getRandomNumber()
    {
        Random rnd = new Random((int)DateTime.Now.Ticks);
        int RandomNumber;
        RandomNumber = rnd.Next(100000, 999999);
        return RandomNumber;
    }
}
