Bind command on tap

[Aster]

Hi,

I'm using your component to display images but i want to add an icommand action when i tap on the image. Obviosly a different behaviour for each image. I've tryied with gestureRecognizer on the image in dataTemplate but the selectedIndex property not updates even with two way binding. Can you help me please?

Hi, 

as an addition, i've managed click in this way:

<rotator:SfRotator.ItemTemplate>

                <DataTemplate>

                    <ffimageloading:CachedImage 

                        Aspect="AspectFill" 

                        DownsampleToViewSize="true" 

                        Source="{Binding Image}" 

                        FadeAnimationEnabled="True" 

                        LoadingPlaceholder="Loading.gif">

                        <ffimageloading:CachedImage.GestureRecognizers>

                            <TapGestureRecognizer

                                Command="{Binding Path=BindingContext.TapCommand, Source={x:Reference MainPage}}" 

                                CommandParameter="{Binding .}" />

                        </ffimageloading:CachedImage.GestureRecognizers>

                    </ffimageloading:CachedImage>

                </DataTemplate>

            </rotator:SfRotator.ItemTemplate>

        </rotator:SfRotator>

So, i've used the TapGestureRecognizer with Command Binding on the image inside data template. The only problem is that now, when i try to swipe the image, it executes the tap command so i cannot swipe the rotator anymore.. help me please!

Hi, 

Any news on this issue? I'm facing the same problem that I can't swipe the rotator because the Tap Command is executed.

I'm using version 15.1.0.37

Thanks,

Hi Ronny,

Thanks for your update.

We were unable to reproduce the reported issue "Unable to swipe Rotator item with adding tapped event on the same in Android" from our side and we have attached the sample with which we checked the reported issue. Please find the sample from the below link.

Sample: http://www.syncfusion.com/downloads/support/forum/127012/ze/RotatorItemTemplate-918501188 

So, could you please provide modified sample which replicates the reported issue as it will help us to provide appropriate solution on this.

Hi,

Thanks for your reply.

The issue happens with your sample as well. However, the VS solution you provided was incorrectly configured. In the "Configuration Properties", the Debug configuration was configured to build and deploy the Release Configuration. This is why the Debug.Writeline statement was never called (or any breakpoints were hit).

Ronny

Hi Ronny,

Thanks for your update.

We would like to let you know that the Rotator items are scrollable but on scrolling, the Tap gesture also gets called. Due to this, the image viewer will be showed in scrolling in your scenario. Unlike Touch events, the Tap gesture added to the image controls works separately for android and gets called on tapping even if we have restricted in our source if the scrolling took place. So, we have created a work around to achieve your requirement of tapping and scrolling and please have the sample from the below link.
