No Pan No Zoom

[bento]

Hi,

I follow and copy example to simple project but error on double tap, cannot pan, cannot zoom. Do you know why ? But when I set Pan="300,300" it can pan, I set Zoom=2, it can zoom. But when image fit screen, error happened.

<Grid x:Name="LayoutRoot"
      Background="Transparent">
    <Image Source="/Assets/AlignmentGrid.png"
           Width="300"
           Height="400"
           Tap="Image_Tap" />
    <telerikPrimitives:RadWindow IsFullScreen="True"
                                 x:Name="imageZoom">
        <telerikPrimitives:RadWindow.OpenAnimation>
            <telerikCore:RadScaleAnimation StartScaleX="0"
                                           StartScaleY="0"
                                           EndScaleX="1"
                                           EndScaleY="1" />
        </telerikPrimitives:RadWindow.OpenAnimation>
        <telerikPrimitives:RadWindow.CloseAnimation>
            <telerikCore:RadScaleAnimation StartScaleX="1"
                                           StartScaleY="1"
                                           EndScaleX="0"
                                           EndScaleY="0" />
        </telerikPrimitives:RadWindow.CloseAnimation>
        <Grid>
            <slideView:PanAndZoomImage ZoomMode="Free"
                                       x:Name="panZoom"
                                       Source="/Assets/AlignmentGrid.png"
                                       MaximumZoom="4" />
        </Grid>
    </telerikPrimitives:RadWindow>
</Grid>

using System;
using Microsoft.Phone.Controls;
namespace PanAndZoom
{
    public partial class RadSlideView : PhoneApplicationPage
    {
        public RadSlideView()
        {
            InitializeComponent();
        }

        private void Image_Tap(object sender, System.Windows.Input.GestureEventArgs e)
        {
            imageZoom.IsOpen = true;
        }
    }
}

Hi Bento,

I got your code running and couldn't replicate your issue. Are you running your example in a simulator or on a device? I am running mine on a device and the PanAndZoomImage is panning and zooming correctly. What exactly was the error you were receiving?

Hello Master,

Yes it is running well first. On Debug mode, double tap make an error and stop here

            if (Debugger.IsAttached)
            {
                // A navigation has failed; break into the debugger
                Debugger.Break();
            }

If running well first, no double tap i made, it cannot zoom or pan, unless i set zoom and pan with a value, for example Pan="300,300" and zoom=2. Debug on Lumia 920 OS Amber version. I tried again without debug, still same situation.

Hello Benyamin,

Thanks for writing.

Can you please send us the project you are reproducing this issue with in a ZIP archive so that we can investigate?

You will need to open a new support ticket to be able to do that.

Hi,

Just updated latest release version of Telerik WP 7 and
noticed that the Pan and Zoom bug is still there.

Maybe the fix was accidently left out from final release version ?

Forced to replace latest dlls with older ones and Pan and Zoom was working ok.

Hello,
Could you, please check the version of the dlls, you've downloaded?
The latest internal build for Windows Phone 7 contains assemblies with version 2013.3.1121.2040 and there the issue should be fixed.

Latest version is 2013.3.1127.2040.
This is what I got using Telerik Control Panel, no internal builds.
Dll file: date modified: 27.11.2013 4:04

Older version: 2013.3.1016.2040, dated 16.10.2013 11:28. This works ok.

Hello Tero,

Your observations are correct.

The issue was fixed in our codebase for WP7, but it hasn't been released yet. This month we release Service Pack 2 where the fix is included.

Apologies for any inconvenience cased and for the misunderstanding.
