Media picker 7.6.3

Using Umbraco And Getting Started

Umbraco 7
Hello,

I am using media picker in umbraco 7.6.3.

And I am using the code
```
    if(CurrentPage.HasValue("pickBannerFolderFromMedia"))
        {       
             var sliders = Umbraco.Media(CurrentPage.pickBannerFolderFromMedia);
foreach(var slider in sliders.Children)
```
But the above is not working.

Thanks for helping.

Hi Kusum,

You need to use something like this
```
Var sliders = Model.Content.GetPropertyValue<IEnumerable<IPublishedContent>>("sliders");
```
where "sliders" is the property name assigned to the media picker. Then your foreach loop should work by saying
```
       foreach(var slide in sliders)
         {
            <img src="@slide.Url"/>
          }
```
Does that help?

Hello Emma,

No its not working.

Actually when I do :
```
 var sliders = CurrentPage.pickBannerFolderFromMedia;
```
I get the id of the media folder. But then I cannot do a foreach to get the images in the folder.

Hi Kusum and Emma

It looks like you don't have property value converter on your project. Try this code:
```
var mediaFolder = Umbraco.TypedMedia(Umbraco.AssignedContentItem.GetPropertyValue<int>("pickBannerFolderFromMedia"));

foreach (var slider in mediaFolder.Children)
{

}
```
Thanks,

Alex

Hello Alex,

Thanks for your reply . It is working.
```
 
<EnablePropertyValueConverters>true</EnablePropertyValueConverters>
```
The property vlue converter is set to true. Do I need to do something else to activate the property value converter please ?

```
<EnablePropertyValueConverters>true</EnablePropertyValueConverters>
```
This property is enough for enabling it.

Thanks,

Ok thanks,

And if I want to get the value of a field in Media

Previouslyt I used to do @slider.textboxOne and it worked. But now it's not working.

Is there any documentation to which I can refer ?

Regards,

kusum

It should work:
```
var value = slider.GetPropertyValue("textboxOne");
```

Sorry to bother you again Alex :

I have tried the below on image cropping
```
@Umbraco.TypedMedia(@slider.id).GetCropUrl("uploadBanner", "large")
```
But not working. I am sorry I am completely lost with this 7.6 :(

It works for me:

var mediaFolder = Umbraco.TypedMedia(Umbraco.AssignedContentItem.GetPropertyValue<int>("pickBannerFolderFromMedia"));

foreach (var slider in mediaFolder.Children)
{
    @Umbraco.TypedMedia(slider.Id).GetCropUrl("uploadBanner", "large")
}

Hello Kusum

"mediaFolder" var is null in your case, can you debug and fix it?

Thanks,

Alex
