Release R1 2020 SP

Blank spaces where rows should appear are observed in the following situation. You start editing a row or a column, then scroll the row outside of the viewport before the edit was committed. Then sort a column.

This is reproducible only if the GroupRenderMode property of RadGridView is set to Flat. Also, the AutoGenerateColumns property should be set to False and the Columns should be added manually.

Note that the issue is reproducible also in RadTreeListView, which has the GroupRenderMode set to Flat by default.

To work this around, set the GroupRenderMode property of RadGridView to Nested.

The RowValidating event arguments give information about the edit operation that triggered the row validation - None, Edit or Insert. However, when the edit is canceled the EditOperationType is set to Edit. Change this and provide a new value (Cancel) or use None when the validation is canceled.

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;
}

To reproduce this:

  1. Use the .NET Core version of the Telerik dlls.
  2. Set the GroupRenderMode of RadGridView to Flat.
  3. Page RadGridView using RadDataPager.
  4. Scroll to the last row in the view. Or scroll to any row so that few of the rows above are not longer visible.
  5. Expand the row details and scroll down more until only the parent row is visible.
  6. Collapse the row details. At this point, the vertical scrollbar disappears and the upper rows are not brought into the view as expected when the row details gets collapsed.

To work this around call the Rebind() method of RadGridView on RowDetailsVisibilityChanged event.

private void RadGridView_RowDetailsVisibilityChanged(object sender, Telerik.Windows.Controls.GridView.GridViewRowDetailsEventArgs e)
{
	if (e.Visibility == Visibility.Collapsed)
	{
		this.gridView.Rebind();
	}        
}

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;
}

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.

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

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.
