RadControls are slow when using at design time in a form containing a lot of controls, split containers and table layout panels

Workaround: manually resize the editor or drag it upwards 

To reproduce:
- Add RadLayoutControl to a form.
- Change the Language property at design time.
- You will receive the following message: There is already a command handler for the menu command '1496a755-94de-11d0-8c3f-00c04fc2aae2 : 103'. 

Workaround:
- Reopen the designer.

Project Update Utility throws unhandled exception when you try to upgrade project which files are not checked-out from source control.

To reproduce: run the sample project, open the test.rtf file and start scrolling with the mouse. As a result, you will encounter the following error:

Workaround:

            this.radChat1.ChatElement.InputTextBox.ButtonsStack.Children.Remove(this.radChat1.ChatElement.ShowToolbarButtonElement);
            this.radChat1.ChatElement.InputTextBox.ButtonsStack.Children.Remove(this.radChat1.ChatElement.SendButtonElement);
            StackLayoutElement stack = new StackLayoutElement();
            stack.MinSize = new Size(0, 60);
            this.radChat1.ChatElement.InputTextBox.Parent.Children.Add(stack);
            this.radChat1.ChatElement.InputTextBox.Parent.Children.Remove(this.radChat1.ChatElement.InputTextBox);
            stack.StretchHorizontally = true;
            stack.Orientation = Orientation.Horizontal;
            stack.Children.Add(this.radChat1.ChatElement.InputTextBox);
            stack.Children.Add(this.radChat1.ChatElement.ShowToolbarButtonElement);
            stack.Children.Add(this.radChat1.ChatElement.SendButtonElement);
            this.radChat1.ChatElement.ShowToolbarButtonElement.StretchHorizontally = false;
            this.radChat1.ChatElement.SendButtonElement.StretchHorizontally = false;

To reproduce: 

-Open the FileExplorer example. 

- Resize the panel (see attached).

As workaround please, rename the controls with Find & Replace from VS Editor.

Use attached to reproduce.

Workaround:

public RadForm1()
{
    InitializeComponent();
    radPdfViewer1.ContainerElement.BookmarksTree.SelectedNodeChanged += BookmarksTree_SelectedNodeChanged;
}

private void BookmarksTree_SelectedNodeChanged(object sender, Telerik.WinControls.UI.RadTreeViewEventArgs e)
{
    Telerik.Windows.Documents.Fixed.Model.Navigation.BookmarkItem bookmark = e.Node.Tag as Telerik.Windows.Documents.Fixed.Model.Navigation.BookmarkItem;

    if (bookmark != null && bookmark.Destination == null)
    {
        GoToAction goToAction = bookmark.Action as GoToAction;
        if (goToAction != null && goToAction.Destination != null)
        {
            radPdfViewer1.PdfViewerElement.GoToDestination(goToAction.Destination);
        }
    }
}

Use attached to reproduce!

How to reproduce: set the ShowIcon property to false.

this.ShowIcon = false;

Use attached to reproduce!

- remove the space from the text in the formatting event so the text is empty

Run the app then drag the left side of the window to the right as far as possible, then rapidly drag the left side of the window back and forth. At some point, the application should crash with the exception (the project is available for download internally only)

Use attached to reproduce.

- In the excel-like filter popup unselect 0.1, 0.2, and 0.3 and then click "Fork"

- When the layout is loaded the values are changed to 1, 2, and 3. 

Workaround:

Change the culture before saving/loading the layout. 

ChildRowHeight can be set on the main table element of the control like this:

this.radGridView1.TableElement.ChildRowHeight = 750;

When the grid is in a hierarchy and a parent row is expanded, the inner child template will create a new table element and its ChildRowHeight is 205 which is the default value. It would be expected that the height of the inner table element is initially set as the height of the main table element of the control.

A possible workaround is to handle the ChildViewExpanded event of the grid this way:

private void RadGridView1_ChildViewExpanded(object sender, Telerik.WinControls.UI.ChildViewExpandedEventArgs e)
{
    GridTableElement tableElement = this.radGridView1.CurrentView as GridTableElement;
    if (tableElement != null && e.ParentRow.HierarchyLevel == 1)
    {
        tableElement.ChildRowHeight = 750;
        tableElement.InvalidateMeasure(true);
    }
}

 

 

Bind the grid to an enumeration, save/load the layout. 

Please refer to the attached sample project and follow the steps illustrated in the gif file.

https://docs.telerik.com/devtools/winforms/controls/gridview/filtering/setting-filters-programmatically-(composite-descriptors)

When creating a composite filter descriptor with a value that contains an array of enums, it generates an expression with IN, and an exception is thrown when adding it to the FilterDescriptors on a RadGridView control.

 

Exception Message:

{"The expression contains undefined function call In()."}

 

The expression value is: ([RandomPropertyName] IN (1,3,9) OR [RandomPropertyName] = 10)

 

We have recently upgraded from 2015.2.728.40 (where this worked) to the Feb. 2019 version, then today upgraded to the May 2019 version. The issue remains.

 

The project includes the following Telerik references:

Telerik.WinControls.PdfViewer

Telerik.WinControls.RadDock

Telerik.WinControls.RadMarkupEditor

How to reproduce: add a MapCallout to a layer and then try to hit test it in the MouseDown event of the control. The element is not always returned even though it contains the mouse location:

private void RadMap1_MouseDown(object sender, MouseEventArgs e)
{
    PointL point = new PointL(e.X - this.radMap1.MapElement.PanOffset.Width, e.Y - this.radMap1.MapElement.PanOffset.Height);
    MapCallout callout2 = this.radMap1.Layers.HitTest(point) as MapCallout;
    if (callout2 != null)
    {
        RadMessageBox.Show("MapCallout!");
    }
}

How to reproduce: 

1. Add a new RadTabbedForm to a VS2017 VB.NET project. 

2. Select the new form in the design view window

3. In the properties box, got to "Tabs" and click the ellipsis (…)

4. The collection editor opens.

5. Click the first tab in the list and change the "Text" property to something new

6. Click "OK"  to save changes
