Event when user pins/unpins a row

[Thomas]

Hello,

I have a grid with a GridViewPinRowColumn and I need to detect, when the user has pinned or unpinned a row. Is there an event which I can subscribe?

Best regards,
Thomas

Hello Thomas,

Currently there isn't such an event, however you can bind the IsPinned property of the row to a property in your model. Here is what I have in mind:

<Style TargetType="telerik:GridViewRow">
            <Setter Property="IsPinned" Value="{Binding IsPinned, Mode=TwoWay}" />
        </Style>

Please, give this approach a try and let me know if it works for your scenario.

There is a strange behavior using this method. 

When the GridView renders an item, the IsPinned property is reset to false... 

meaning : I'm getting a PropertyChanged event on my items that are bound to IsPinned, when the GridView renders. 

This means that i somehow needs to have a flag that locks change notifications while the GridView is rendering :-/

To make matters even worse - There is no reliable event that tells me when the GridView has finished rendering !!!!

Hello Martin,

I have provided an answer to this forum thread that was opened regarding this matter. Could you give the approach, that was suggested there, a try? If you have any further questions regarding this, please forward them to the proposed forum.

Hello Vladimir,

thanks for your reply. In the meantime I have found a workaround accessing the private property PinnedItemsView:

PropertyInfo pinnedProperty = typeof(DataItemCollection).GetProperty("PinnedItemsView", BindingFlags.NonPublic | BindingFlags.Instance);
QueryableCollectionView pinnedItems = pinnedProperty.GetValue(myGrid.Items) as QueryableCollectionView;
pinnedItems.CollectionChanged += ...

 

But I will try your approach to make this less hacky.

Thomas
