Hello,

I have a RadDataForm synchronised with a RadGridView. The navigation buttons work perfectly when I have not grouped the grid by any of the columns. As soon as I do, the navigation buttons seem to get a bit confused, whereby sometimes one or more of the buttons might be disabed e.g. the move-current-to-next button is disabled when there are still heaps of subsquent records).

Remove the grouping on the GridView and everything works fine once again.

Not sure if this has anything to do with the IComparable implementation I've done for the CollectionViewSource ??
I've basically bound my GridView to a CollectionViewSource which is defined in XAML as follows:
<CollectionViewSource x:Name="cvs" Source="{Binding PackagedCosts}">
    <CollectionViewSource.SortDescriptions>
        <scm:SortDescription Direction="Ascending" />
    </CollectionViewSource.SortDescriptions>
</CollectionViewSource>

PackagedCosts is an ObservableCollection of type FlattenedPackageCost, which has a IComparable.CompareTo defined as follows:
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
public string ParentName { get; set; }
 
internal string Compare
{
    get { return string.Join(" ", new[] {ParentName, StartDate.ToString("yyyyMMdd"), EndDate.ToString("yyyyMMdd")}); }
}
 
public int CompareTo(object obj)
{
    var advertPackagedCost = obj as FlattenedPackagedCost;
    return advertPackagedCost != null ? String.CompareOrdinal(Compare, advertPackagedCost.Compare) : 0;
}

The gridview is grouped by ParentName.

Kind regards,
Steve

Hi Steven,

I think I managed to reproduce the issue even on our demos and it is not related to the implementation of IComparable. Could you try this demo to confirm whether it is the same one? (I have reproduced it by editing a Salary for a particular person so that there are two item with same value and group by Person).
Thank you for your cooperation.

Thanks for the response Maya.

The demo is one that I had looked at and it does exactly mimic my scenario, however, I can't reproduce the problem in the specified demo (possibly due to there being no grouping that will have more than 1 record in a group, which you did mention you modified and managed to reproduce the issue). Please let me know if this is not the confirmation you were after??

Kind regards,
Steve.

Hi Steven,

Indeed, this is most probably the exact same issue. Thank you a lot for the cooperation. I will investigate it and write you back as soon as I have more information on it.
