SfRotator loading images from the internet

[Salem Korayem]

I was surprised to discover that SfRotator doesn't accept SfRotatorItem Image source from the internet. I thought its implementation is similar to XF Image which accepts both local or online images.

Any idea how can I achieve that?

Hi Salem,

Thank you for contacting Syncfusion Support.

Currently, SfRotatorItem's Image API can accept only string values in which you can assign the image names as shown below.

Code example:

SfRotatorItem item =new SfRotatorItem ();
item.ImageName="image.png";

Due to some stability issues, we had postponed the Custom View support for the Rotator control and it will be available in our upcoming 2016 Volume 2 release which is expected to be roll out by the mid of June, 2016. By using this custom View support, you can achieve your requirement of assigning the Images via URL. Please visit our website periodically for updates regarding releases.

Regards,
Paul Anderson

hi , Can u explain how can i use sfRotator in Xamarin forms?? i am unable to bind the data to the rotator?  i am unable to see the dots too?

[uday kumar]

thank you!! I got the Idea!! Its working Fine. :) Plz Anybody suggest me how can i display the rating that i am giving on to a label?? i am unable to bind the rating value to a label!!.....

Hi Uday kumar,

Thanks for your update.

Query: unable to bind the rating value to a label

You can achieve this by representing the mode of binding label with “TwoWay”. It necessary to inherit INotifyPropertyChanged in your view model as in the following code example,

Code Example:  

 

//Xaml code   

  <Label x:Name="text2"  Text="{Binding Rating, Mode=TwoWay}"/>   

  //view model class with INotifyPropertyChanged   

public event PropertyChangedEventHandler PropertyChanged;   

protected void RaiseProeprtyChanged([CallerMemberName]string propertyName = "")   

{   

   if (this.PropertyChanged != null)   

   this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));   

}   

We have created a sample for achieving your requirement to bind rating value to label. Please download that sample from the following link

Hi ,

when i use sfrating bar in my xamarin forms.. i found that the size of the stars are varying and in android its looking ugly (blurred stars with background color of stars changing when we tap the stars) and also when i want to give a 5 out of 5 rating , it is not taking 5 rating even if i click on the right half of the star (5th star). if i click outside(right to the 5th star) of the 5th star it is giving 5 rating In IOS. Please suggest me how to overcome this?

I use the sfRotator with URL but the most images show a blank image, maybe the images don't load fully before the control loads, I guess.

I tried to add FFImageLoading (CachedImage) but I receive a null reference exception after asign the ItemsSource.

There are not URL examples in the examples section :/

Hi Christian, 

 

We have prepared the SfRotator sample based on your requirement in which we have added the image inside the rotator item using URL and we were unable to reproduce the reported issue "Image doesn't load inside rotator". Please have the sample with the screenshot below.
