To reproduce:

Add a RadBindingNavigator to a form and change its name.

Bind it to something.

Workaround:

Leave the default name.

To reproduce:

See the attached video.

To reproduce:

Add page view with some pages.

Add a scrollable panel with some labels on the page.

The labels have different BackColor 

Workaround:

 radScrollablePanel1.PanelElement.Fill.BackColor = Color.FromArgb(245, 246, 247);
 //or
 radScrollablePanel1.BackColor = Color.FromArgb(239, 239, 239);

To reproduce:

- Open the Print Preview dialog and select "Print Entire Workbook"

- Nothing happens and only the current sheet is printed

To reproduce:

- add a drop-down list to a form and set the AutoCompleteMode to suggest

- set the theme to Fluent

- the drop-down list is higher than the other editor

Hello,

I have a very simple form that has this code:

 

 

At the start it call the SetStartForm() method that with a lot of other things hide the groupbox.

Well after a search when a user click again the button "Nuova Ricerca" I call again SetStartForm() but the components rendering remain with the border. Please see the video:

//video has been deleted due to sensitive data.

How can I solve that? Thanks

Until released the text can be cleared this way:

GridSearchCellElement searchCell = this.radGridView1.TableElement.FindDescendant<GridSearchCellElement>();
if (searchCell != null)
{
    searchCell.SearchTextBox.Text = "";
}

To reproduce:

- Open the Excel-like filtering example in the demo application and sort the second column. 

- The sort icon is over the text. 

Workaround:

private void RadGridView1_SortChanged(object sender, Telerik.WinControls.UI.GridViewCollectionChangedEventArgs e)
{
    this.radGridView1.TableElement.Update(GridUINotifyAction.StateChanged);
}

Environment: Telerik WinForms 2018.3.1016.40, VS 2013 Pro U5, Win 10 Ent 64 1809 17763.195

Steps:

Create a new WinForm project with default settings

Add a RadForm with default settings

Add a RadScrollablePanel to the RadForm with default settings

Add a RadPanel inside the RadScrollablePanel with default settings

Add a 3 RadRadioButtons to the RadScrollablePanel  with default settings

Select all 3

Press Ctrl+X to cut the radio buttons.

Actual Result: Visual Studio will immediately hang and any unsaved project work will be lost.

Actual Desire: To be able cut and paste the 3 radio buttons into the RadPanel, just like normal MS WinForm controls in design-time.

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;
        }
    }

}

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;
}

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:

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;

 

The form fields are not visible in a document created with Foxit pdf-editor.

The application may freeze for a small period of time if the page view control is created in the DoWork event of BackgroundWorker and later added to the form in its RunWorkerCompleted event.

To reproduce:

- Set the MaxDropDownItems and the DefaultItemsCountInDropDown and open the popup on HDPI.

How to reproduce: test the attached project with the latest version on a Windows 7 machine, notice that the font sizes are scaled, test the project with assemblies before  R2 2017 the fonts are not scaled

The issue is observed even with the RadControl.EnableDpiScaling property set to false. It would be expected that if the property was set to false, that the fonts would not be increased.

Workaround: change the fonts for each of the controls individually, the scaling can be calculated this way:
  Protected Overrides Sub OnShown(e As EventArgs)
        MyBase.OnShown(e)

        Dim dpi = NativeMethods.GetSystemDpi()
        Dim scale = dpi.X / 96.0
    End Sub

How to reproduce: create the following custom cell and notice that the collapsed elements would still occupy space inside the cell. Check the attached screenshot

public class PNUDFCellElement : GridDataCellElement
{
    public PNUDFCellElement(GridViewColumn column, GridRowElement row) : base(column, row)
    {
    }

    private CustomStackLayoutElement stack;
    private RadDropDownListElement radDropDownListElement;
    private RadDateTimeEditorElement radDateTimeEditorElement;
    private RadTextBoxControlElement radTextBoxElement;

    protected override void CreateChildElements()
    {
        base.CreateChildElements();
        stack = new CustomStackLayoutElement();
        stack.StretchHorizontally = true;
        stack.Orientation = Orientation.Horizontal;
        radDropDownListElement = new RadDropDownListElement();
        radDropDownListElement.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;
        radDropDownListElement.StretchHorizontally = true;
        radDateTimeEditorElement = new RadDateTimeEditorElement();
        radDateTimeEditorElement.StretchHorizontally = true;
        radTextBoxElement = new RadTextBoxControlElement();
        radTextBoxElement.StretchHorizontally = true;
        stack.Children.Add(radDropDownListElement);
        stack.Children.Add(radDateTimeEditorElement);
        stack.Children.Add(radTextBoxElement);
        this.Children.Add(stack);
    }

    protected override void SetContentCore(object value)
    {
        this.radDropDownListElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
        this.radTextBoxElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
        this.radDateTimeEditorElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

        this.DrawText = false;
        if (this.RowIndex % 3 == 0)
        {
            this.radDropDownListElement.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            this.radDropDownListElement.Text = this.Value + "";
        }
        else if (this.RowIndex % 3 == 1)
        {
            this.radTextBoxElement.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            this.radTextBoxElement.Text = this.Value + "";
        }
        else
        {
            this.radDateTimeEditorElement.Visibility = Telerik.WinControls.ElementVisibility.Visible;
        }

        base.SetContentCore(value);
    }
}

public class CustomDataColumn : GridViewDataColumn
{
    public CustomDataColumn(string fieldName) : base(fieldName)
    {
    }

    public override Type GetCellType(GridViewRowInfo row)
    {
        if (row is GridViewDataRowInfo)
        {
            return typeof(PNUDFCellElement);
        }
        return base.GetCellType(row);
    }
}

Workaround: use a custom StackLayoutElemetn
public class CustomStackLayoutElement : StackLayoutElement

    protected override void ArrangeHorizontally(SizeF finalSize)
    {
        RectangleF clientRect = this.GetClientRectangle(finalSize);

        foreach (RadElement element in this.Children)
        {
            if (element.Visibility == ElementVisibility.Collapsed)
            {
                continue;
            }

            if (element.StretchHorizontally)
            {
                stretchableCount++;
            }
            else
            {
                stretchableWidth += element.DesiredSize.Width;
                nonStretchableItems++;
            }
        }

        if (nonStretchableItems > 0)
        {
            stretchableWidth += ElementSpacing * (nonStretchableItems - 1);
        }

        int spacing = this.ElementSpacing;

        if (stretchableCount > 0)
        {
            stretchableWidth = (clientRect.Width - stretchableWidth) / stretchableCount;
            stretchableWidth -= spacing * stretchableCount;
        }

        ArrangeItemsHorizontaly(clientRect, finalSize, stretchableWidth, spacing);
    }

    protected override void ArrangeItemsHorizontaly(RectangleF clientRect, SizeF finalSize, float stretchableWidth, float spacing)
    {
        float x = clientRect.X;
        float y = clientRect.Y;

        List<RadElement> children = new List<RadElement>(this.Children);

        if (this.Comparer != null)
        {
            children.Sort(this.Comparer);
        }

        for (int i = 0; i < children.Count; i++)
        {
            RadElement element = null;

            if (this.RightToLeft && this.RightToLeftMode == RightToLeftModes.ReverseItems)
            {
                element = children[children.Count - i - 1];
            }
            else
            {
                element = children[i];
            }

            if (element.Visibility == ElementVisibility.Collapsed)
            {
                continue;
            }

            RectangleF proposedRect = new RectangleF(x, y, stretchableWidth, clientRect.Height);
            RectangleF finalRect = AlignRect(element, proposedRect);

            if (this.RightToLeft && this.RightToLeftMode == RightToLeftModes.ReverseOffset)
            {
                finalRect.X = finalSize.Width - x - finalRect.Width;
            }

            this.ArrangeElement(element, clientRect, finalRect, finalSize);

            x += finalRect.Width + spacing;
        }
    }
}
