We noticed that RadGridView does not get garbagecollected sometimes.
So i fired up  a memory analyzer to see what is going on.

This is the graph that shows that the RadGridView is causing a leak. The only references that keep the GridView from getting collected are those two WeakEventListeners

To further investigate i decompiled GridViewDataControl and could identify the culprit.

private void SubscribeToDispatcherShutdown()
    {
      if (this.dispatcherShutdownListener != null)
        this.dispatcherShutdownListener.Detach();
      this.dispatcherShutdownListener = new WeakEventListener<GridViewDataControl, object, EventArgs>(this);
      this.dispatcherShutdownListener.OnEventAction = (Action<GridViewDataControl, object, EventArgs>) ((grid, source, eventArgs) => grid.OnDispatcherShutdownFinished(source, eventArgs));
      this.dispatcherShutdownListener.OnDetachAction = (Action<WeakEventListener<GridViewDataControl, object, EventArgs>>) (weakEventListener => this.Dispatcher.ShutdownFinished -= new EventHandler(this.dispatcherShutdownListener.OnEvent));
      this.Dispatcher.ShutdownFinished += new EventHandler(this.dispatcherShutdownListener.OnEvent);
    }

In the second line from the botton

... weakEventListener => this.Dispatcher.ShutdownFinished -

Hi Telerik-Team,

When creating a new item in the GridView by either mouse or insert button the row is not selected or highlighted.

I guess this is a bug, since a cell in the new row has focus but not the row.

Best regards,

Mats

When the ItemsSource is not set: ArgumentOutOfRangeException is thrown

When the ItemsSource is set to an empty collection: DivideByZeroException is thrown

The designer throws an error when the default style of a control which has a RadSplitButton/RadDropDownButton in its control template is extracted in a ResourceDictionary and then merged in App.xaml. There must be a custom style which is based on the extracted one to reproduce the error. This behavior is only present in 2019 R3.

The error is "This feature requires service 'Microsoft.Windows.Design.Services.ValueTranslationService' to be present, but it could not be located."

Hi,

I have been working wit the RadGridView for about 6 years now and it works great!

The only thing that still bugs me after all these years is the GridViewComboBoxColumn. The sorting and "Search as you type" features are not working for us. The fact that it uses the DataMemberBinding is something we do not get.

The fact that it is not ordered or searched into the shown value instead of the DataMemberPath is beyond me.

I mean, why would I, as a user, want to search into or sort a value that is not visible to me?

Adding a feature like a string property on the GridViewComboBoxColumn that is used for displaying, searching, filtering and sorting would be awesome!

The filter's distinct values work well, but the field filters show the enum value and that's not good.

I have attached a sample project to demonstrate the problems with sorting, filtering and searching.

There are also print screens attached to clarify each feature mentioned

Thanks!

When adding a new row and we click inside a DropDownContent of a DropDown control, the RadGridView loses focus. This way RowValidating event is called which is not expected.

In Office2016 when we increase the DPI of the Windows a left border in the header of column disappears. As a workaround you can set the Width property of all columns.

 Group rows which are not present in the view are not visualized when the window is maximized.

A possible solution here is to set the GroupRenderMode property to Flat.
