A simple thing I want to do, just compare two values.
I got a value I pass in to my partial view macro:
var numberToDisplay = Model.MacroParameters["numberToDisplay"];
Then later, I am looping through a collection inside of foreach block.
@foreach (var item in myCollection) { }
I can print both of these values individually in my foreach block:
<p>@numberToDisplay</p>
and
<p>@item.Index()</p>
Where @item.Index() does increment. But when I try to compare them, like this (still inside a foreach block):
if(item.Index() < numberToDisplay) { <p>do some stuff</p> }
It breaks.
I have tried casting the values to an Int before comparing, like this:
int max = int.Parse(item.Index()); int pos = int.Parse(numberToDisplay);
But I can't even do that w/o it breaking.
Can't I just do a simple numeric comparison in Razor?
Hi Jacob,
This seems to work ok:
@inherits Umbraco.Web.Macros.PartialViewMacroPage @{ var myCollection = CurrentPage.AncestorOrSelf(1).Children; var numberToDisplay ="2"; foreach (var item in myCollection) { if(item.Index() < int.Parse(numberToDisplay)) { <p>do some stuff</p> } } }

Hmmm,
The only way I can get it to work is like this:
foreach (var item in myCollection) { var testit = "2"; @if(item.Index() < int.Parse(testit)) { <p>some stuff</p> } }
Obviously, that says there is something strange about the var numberToDisplay.
numberToDisplay is set like this:
The scope seems global to the partial view since it is defined at the top. And I can confirm it is populated by just echoing it: @numberToDisplay
Maybe try var numberToDisplay = Model.MacroParameters["numberToDisplay"].ToString();
var numberToDisplay = Model.MacroParameters["numberToDisplay"].ToString();
That's it. Thank you so much.
You're welcome, it is required because Model.MacroParameters["numberToDisplay"] returns a object type.
