There is a bug overriding the method ProvideCommandsForKey(Key key) in DefaultKeyboardCommandProvider.
When pressing F10, the received key is Key.System.

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 -
... you are using 'this.Dispatcher...' which causes the leak since the Action will implicitly capture the 'this' reference.
Which kind of defeats the prupose of having a WeakReference inside your WeakEventListener.

Sadly i cannot figure out how it happens, but i think its only when Detach (FrameworkElement.Unloaded ultimately) is not called.
While this is the actual issue, i thought I'd share this with you so you.

There is not a dedicated UI that allows hiding showing columns. You can achieve this using Control Panel functionality.

A property like FilterMemberPath could be created. This way, we can control which property will be used by the Search As Type functionality.

The search box TextBox element used with the search-as-you-type feature is not focused when you press the Tab key. This happens because the search box is excluded from the tab order (IsTabStop=False).

Use the ChildrenOfType extension method to get the TextBox element and set its IsTabStop to True.

private void gridView_Loaded(object sender, RoutedEventArgs e)
{
	var searchBox = this.gridView.ChildrenOfType<TextBox>().FirstOrDefault(x => x.Name == "PART_SearchAsYouTypeTextBox");
	searchBox.IsTabStop = true;
}

The ItemsControl that holds the control panel of RadGridView should not be included in the tab order. Its IsTabStop property should be False. Only the items inside of it should be included in the tab order.

To work this around, use the ChildrenOfType extension method to get the ItemsControl and set its IsTabStop property. Optionally, you can exclude also the ControlPanelItemControl elements from the tab order.

private void gridView_Loaded(object sender, RoutedEventArgs e)
{
	var controlPanel = this.gridView.ChildrenOfType<ItemsControl>().FirstOrDefault(x => x.Name == "PART_ControlPanelItemsControl");
	controlPanel.IsTabStop = false;
}

Bind a grid to a DataView

Start editing and change the values of a few cells.

Press Escape twice to cancel the edit of the entire row.

Expected: the values return to the old values

Actual: the values remain the last entered ones

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!

Currently, a CollectionChanged notification of the bound collection needs to be raised for the Filtering/Sorting/Grouping to be updated.

Our requirement is to navigate through RadGridView table header using keyboard tab navigation.

The header may or may not include checkbox/filter button.

However on mouse focus on table headers , it get highlighted. This feature is currently not possible with tab navigation.

When two columns in two separate column groups have the same name and they belong two separate column groups, the column group names of the parent column groups can be appended to the display content of the GridViewGroupPanelCells.

For example, the duplicate Code columns in the attached image should have content "PG Code" and "VENUE Code" respectively.
