Hi Elena,

I produced a video to illustrate the issue, but have wasted too much time trying to get it below the 200k limit for attached files on your forum. Could you please give me an email address that I send it to.

Hello Matt,

Thank you for the video. Now I succeed in reproducing the issue and I am going to forward this to our developers.  I will get back to you as soon as I have any additional information for you about this.

Hello Matt,

We have logged the scroll issue that you reported in our internal tracking system with a Development ID of 108460. I will provide you with more details about it through support case  CAS-88447-H07Q40.

Hello,

Our developers are still working on this issue still as workaround you can try to handle the IsVisibleChanged event of the thumb of the horizontal scrollbar as follows: 

   Thumb horizontalThumb =Utilities.GetDescendantFromType(temp, typeof(Thumb), false) as Thumb;

            horizontalThumb.IsVisibleChanged += new DependencyPropertyChangedEventHandler(horizontalThumb_IsVisibleChanged);

        void horizontalThumb_IsVisibleChanged(object sender, DependencyPropertyChangedEventArgs e)

        {

            if (!(bool)e.NewValue)

            {

                xg.InvalidateData();

            }          

        }

Hello Elena,

Has this issue been resolved? It happens in our product as well.

Hello Daniil,

Thank you for posting the workaround to this issue. I believe it may help others who are having a similar issue.

I have tested this scenario against the latest versions of Infragistics WPF 17.1 and 17.2, and it appears that this issue has been fixed as I am no longer able to reproduce this behavior. Unfortunately, it does not appear that this fix made it into the latest 16.2 build, which was the last, and so you may need to either continue using the workaround, or upgrade to the latest versions of 17.1 / 17.2.

Please let me know if you have any other questions or concerns on this matter.

I have verified that this issue is still present in 16.2.20162.2109, and therefore suggest you to test later releases as well.

For those who have stumbled across this as well, the workaround suggested in this thread doesn't work, so you will need to modify the template and wrap your ScrollBar into some containing element, i.e. Border, and when you have references to both ScrollBar and that element, you would subscribe to ScrollBar's IsEnabledChanged and set the parent's Visibility based on NewValue:

var border = scrollBar.Parent as Border;
scrollBar.IsEnabledChanged += (s, e) =>
{
    border.Visibility = (bool)e.NewValue ?
    Visibility.Visible : Visibility.Collapsed;
};

Hello Narendra Singh,

Thank you for posting in the Infragistics Community.

I have verified that this issue is being fixed in the version 12.1.20121.2169 and up. The latest one available is currenly 12.1.20121.2225. In order to download and test it, you could go to your account, click on the corresponding 12.1 product key, and choose the "Service Releases" below the keys, and there you could download the latest available one for you.

Please feel free to let us know if you have any other questions with this matter.

Hi Elena,

I am experiencing the issue too in wpf xamGrid and the build version I am currently working is 12.1.20121.1010. The mentioned URL has certain releases however after August 2012 there are only 2 which are for ASP.NET and Winform.

Can you please confirm if the issue has been addressed for WPF too? If so, from where we can download the fix.

Thanks,
