Here is the situation :
On a MVC application I have a partial that is rendering a script bundle. this partial is rendered several times.
Is there a built-in way to determine an specific Bundle is rendered before in some place on page ?
Thanks professionals
Update : here is the code for clearing the condition
main layout :
<html>
<body>
@if(someCondition){
@Html.RenderPartial("SamePartial")
@Html.RenderPartial("SamePartial")
@Html.RenderPartial("SamePartial")
}
</body>
</html>
and this is inside partial :
<div>Blah Blah Blah</div>
@Scripts.Render("~/bundles/JusNeededInsidePartial")
@Styles.Render("~/Themes/styles/JusNeededInsidePartial")
partial is rendered several times. I need a way to render bundles 1 time only

Define a Razor section:
@section MySpecialScripts {
@Scripts.Render("~/bundles/MySpecialScriptsBundle")
}
in views where you need such scripts and add the following to the main layout:
@if (IsSectionDefined("MySpecialScripts")) {
RenderSection("MySpecialScripts")
}

I'd be a bit leery about putting bundles inside your partial views like you are doing.
For best performance, I'd suggest putting scripts at the bottom of your page (ref: http://developer.yahoo.com/blogs/ydn/high-performance-sites-rule-6-move-scripts-bottom-7200.html)
If your bundles contain stylesheets, you're going to be putting them in the body, which is still valid, but I like to organize them so that they're all together.
Typically what I would do is add this to my _Layout.cshtml right before the closing </head> tag:
@RenderSection("Head", required: false)
Then, in my View, I could have:
@Html.RenderPartial("SamePartial")
@Html.RenderPartial("SamePartial")
@Html.RenderPartial("SamePartial")
@section head{
@Scripts.Render("~/bundles/myBundle")
}
And if I wanted to do something similar on another View:
@Html.RenderPartial("OtherPartial")
@Html.RenderPartial("OtherPartial")
@section head{
@Scripts.Render("~/bundles/myOtherBundle")
}
I know this is a bit different than what you were asking for, but I think there's value in the flexibility of this solution.
And if you're loading things dynamically, you could always put a simple condition in your section:
@section head{
@if(SomeCondition){
@Scripts.Render("~/bundles/modernizr")
}
}
