To reproduce: open the Demo application >> VirtualGrid >> First Look example. Follow the steps illustrated in the attached gif file. You will notice that when you expand a row, the "-" sign is show for a second and then it is returned to "+" although the row is still expanded. 

Workaround:
            this.radVirtualGrid1.CellFormatting += radVirtualGrid1_CellFormatting;
            this.radVirtualGrid1.RowExpanded += radVirtualGrid1_RowExpanded;
            this.radVirtualGrid1.RowCollapsed += radVirtualGrid1_RowCollapsed;



        private void radVirtualGrid1_RowCollapsed(object sender, VirtualGridRowExpandedEventArgs e)
        {
            if (expandedState.ContainsKey(e.RowIndex))
            {
                expandedState[e.RowIndex] = !expandedState[e.RowIndex];
            }
           
            this.radVirtualGrid1.TableElement.SynchronizeRow(e.RowIndex, true);
        }

        Dictionary<int, bool> expandedState = new Dictionary<int, bool>();

        private void radVirtualGrid1_RowExpanded(object sender, VirtualGridRowExpandedEventArgs e)
        {
            if (!expandedState.ContainsKey(e.RowIndex))
            {
                expandedState.Add(e.RowIndex, false);
            }
            expandedState[e.RowIndex] = !expandedState[e.RowIndex];
            this.radVirtualGrid1.TableElement.SynchronizeRow(e.RowIndex, true);
        }

        private void radVirtualGrid1_CellFormatting(object sender, Telerik.WinControls.UI.VirtualGridCellElementEventArgs e)
        {
            VirtualGridIndentCellElement indentCell = e.CellElement as VirtualGridIndentCellElement;
            if (indentCell != null)
            {
                if (expandedState.ContainsKey(e.CellElement.RowIndex) && expandedState[e.CellElement.RowIndex] == true)
                {
                    indentCell.ExpanderItem.SignImage = Properties.Resources.chevron_up;
                }
                else
                {
                    indentCell.ExpanderItem.SignImage = Properties.Resources.chevron_down;
                }
            }

RadVirtualGrid shold automatically adjust the height of the visible cells/rows only. When you perform scrolling horizontally or vertically, the respective scrollbar will be adjusted. The scrollbar may shrink or enlarge considering the currently displayed data. Have in mind that when you have a horizontal scrollbar, the row's height will be calculated according to the content of the visible cells on the row. If you scroll horizontally and some of the cells on the row get hidden and others get visible, the row's height should be adjusted according to the content. Initially, this behavior may be confusing for the users, however since data is loaded on demand in RadVirtualGrid, you need to autosize the rows on demand as well.

RadRichTextEditor: MoveToDocumentElementStart works incorrectly when called consecutively with PermissionRangeStart as parameter
When the MoveToDocumentElementStart is called with parameter that is PermissionRangeStart and then is called a second time, the position moves to the previous position instead.

Hello, we have found another small bug of the RadVirtualGrid control.

When paging is enabled on child view, one of the component of the paging panel overlap whit is parent.

I attach source code and screenshot.

 

Thanks in advance.

When you setup a hierarchical RadVirtualGrid and set the UseScrollbarsInHierarchy property to false and use VirtualGridAutoSizeColumnsMode.Fill for the child template, you expect that the column's width is calculated according to the total width of the respective template. Hence, if you shrink or enlarge the grid, the columns will shrink/enlarge respectively. However, if you double click the resize cursor between the column headers you will notice that the best-fit action is performed over the column and its width is adjusted. However, the VirtualGridAutoSizeColumnsMode.Fill setting is not respected and you either can't see all the columns, or you obtain some empty space if the column doesn't need much space.

Sometimes when copying from word is duplicating some parts of the text.

 

1 - Open the Telerik WinForms Demo Application;

2 - Go to RichTextEditor;

3 - Click on First Look;

4 - Delete All the text (Ctrl + A then Delete);

5 - Open the word document Attached;

6 - Select Everything (Ctrl + A) and copy;

7 - Paste on the RichTextEditor;

8 - The end of the second paragraph is duplicated;

How to reproduce: 
float ratio = .5f;
private void radButton1_Click(object sender, EventArgs e)
{
    float ratio = .5f;
    this.radPdfViewer1.ExportPage(1, @"..\..\img.jpeg", ratio, true, ImageFormat.Png);
}

Workaround: change the resolution of the document after exporting it with a ratio = 1
private void radButton1_Click(object sender, EventArgs e)
{
    float ratio = .5f;
    Bitmap bmp = this.radPdfViewer1.ExportPage(1, 1, true, ImageFormat.Png);
    Bitmap resizedImage = this.ResizeImage(bmp, (int)(bmp.Width * ratio), (int)(bmp.Height * ratio));
    resizedImage.Save(@"..\..\img2.jpeg");
}

public Bitmap ResizeImage(Image image, int width, int height)
{
    Rectangle destRect = new Rectangle(0, 0, width, height);
    Bitmap destImage = new Bitmap(width, height);
    destImage.SetResolution(image.HorizontalResolution, image.VerticalResolution);

    using (var graphics = Graphics.FromImage(destImage))
    {
        graphics.CompositingMode = CompositingMode.SourceCopy;
        graphics.CompositingQuality = CompositingQuality.HighQuality;
        graphics.InterpolationMode = InterpolationMode.HighQualityBicubic;
        graphics.SmoothingMode = SmoothingMode.HighQuality;
        graphics.PixelOffsetMode = PixelOffsetMode.HighQuality;

        using (var wrapMode = new ImageAttributes())
        {
            wrapMode.SetWrapMode(WrapMode.TileFlipXY);
            graphics.DrawImage(image, destRect, 0, 0, image.Width, image.Height, GraphicsUnit.Pixel, wrapMode);
        }
    }

    return destImage;
}

Hello,

We have developed an ASP.NET application and a WinForms application that both uses Telerik RadScheduler. The applications share the same data.

We have set EnableExactTimeRendering = true to prevent appointments to falsely be displayed as collisions.

Our problem is that appointments with short durations (0-4 minutes) are totally invisible in the WinForms Scheduler. In the ASP.NET scheduler all appointments are visible. An appointment with no duration (0 minutes) is shown as 30min appointment in ASP.NET while 1-minute appointments are shown as a thin line which is ok as we use tooltips for all appointments.

How can we make all appointments visible in WinForms and still use EnableExactTimeRendering? Of course, the rendering will not be exact for small durations but that is better than not showing the appointments at all. We would like to set a minimum size for appointments.

Best regards,
Daniel Gidlöf

To reproduce: 
- When the filter is set to contains the item is different than the item is selected from the drop-down and the text is taken from the append functionality.

I have a custom Fluent theme as a package, it would be nice if there was a way to load packages (Embedded Resource or files) with the RadThemeManager.

Rather than typing this: Telerik.WinControls.ThemeResolutionService.LoadPackageResource("GUI.Themes.Fluent_Custom.tssp");

Right now the RadThemeManager only supports XML files. Feeding it a tssp file doesn't work.

 

For it to show up in design-time I have to assign it all of the unpackaged XML files and then delete the RadThemeManager for the theme to show up, otherwise the load time is like 7 seconds, where as embedded packages load super fast.

The fluent theme has a lot of XML files and this is a huge pain, supporting 1 Embedded Resource tssp package would be nice.

 

Would also be nice if the RadThemeManager could apply/change a theme globally somewhere in the SmartTag menu or RadThemeManager properties.

Instead of having to type this: ThemeResolutionService.ApplicationThemeName = "Fluent_Custom";

Use attached to reproduce:

- click on the second tab

- collapse the first group

- click the first tab

- click the second tab, both grids are visible

Workaround:

public RadForm1()
{
    InitializeComponent();
    new Telerik.WinControls.RadControlSpy.RadControlSpyForm().Show();

    layoutControlGroupItem3.PropertyChanged += LayoutControlGroupItem3_PropertyChanged;

}

private void LayoutControlGroupItem3_PropertyChanged(object sender, PropertyChangedEventArgs e)
{
    if (e.PropertyName == "IsHidden" || e.PropertyName == "IsExpanded")
    {
        if (layoutControlGroupItem3.IsExpanded)
        {
            layoutControlGroupItem3.ContainerElement.Items[0].Visibility = Telerik.WinControls.ElementVisibility.Visible;
        }
        else
        {
            layoutControlGroupItem3.ContainerElement.Items[0].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
        }
    }

}
