We are currently using version 2017.3.1017.40 and noticed an issue with the display of the RadSplitButtonElement in combination with the theme Office2010Blue.
When we disable the RadSplitButtonElement, or more precisely the ActionButtonElement in the DropDownEditorLayoutPanel, it does not display as disabled in the Office2010Blue theme.
In other themes (e.g. Office2010Silver) it does show as disabled.

When trying the latest version (2020.2.616.40) we still get this behaviour, see example below:

It appears similar to the issue mentioned in https://feedback.telerik.com/winforms/1370576-fix-radcommandbar-some-of-the-elements-in-the-control-are-not-rendered-as-disabled-with-office2010blue-and-office2010black-themes

Hi Support team,

UI for WinForms - Latest version.

RadRibbonBarBackstageView - Edit UI Elements

RootRadElement.BackstageViewElement.BackstageItemsPanelElement.BackgroundImage

Click the … button and select your image.

To REMOVE this image you SHOULD be able to do the following:

click on the property BackgroundImage which should highlight the image-string completely.

click delete.

done.

What you HAVE to do is this: 

click on the property BackgroundImage.

click delete.

BEFORE YOU LEAVE THIS PROPERTY you have to click the … box

Once the box opens you have to click "Cancel"

Right below this property is BackgroundImageLayout - set to "Center"

There's a dropdown arrow presumably to allow you to change the layout but nothing happens when you click it.

*Missing Property?*

Whatever image you place in this control it gets stretched and there doesn't appear to be any way to avoid this:

place an image.

run the winforms ap.

set the main form in normal mode (not maximized) and resize the height.

Your image will stretch, shrink...this is not a UI property that should be presumed.  We should be able to set None, Tile, Center, Stretch or Zoom.

Still *LOVE* your products :)

Kindest regards,

Curtis Smith 

Dear,

I wonder if it is possible to consult the release history by product & control & version, next to the (already existing) release history by product & version & control?

This feature has benifits:

• see how a given control evolves in time
• quickly find if a bug/feature has been implemented by control

This request can be applied for all your products.

Kind regards,

Peter

If you have two RadGridView controls and you want to export both of the grids to a common file on two different sheets, it is suitable to use FileExportMode.NewSheetInExistingFile. However, when using the export overload to a stream doesn't respect the ExportMode.

Workaround: use exporting to a file:

            string exportFile = @"..\..\exportedData.xlsx";
            GridViewSpreadStreamExport spreadStreamExport = new GridViewSpreadStreamExport(this.radGridView1);
            spreadStreamExport.FileExportMode = FileExportMode.NewSheetInExistingFile;
            spreadStreamExport.ExportVisualSettings = false;
            spreadStreamExport.RunExport(exportFile, new SpreadStreamExportRenderer());

Hi there,

We have recently found a bug on both the RadDocument and Rad Rich Text Editor. Created a RTF document via the RadRichText Editor. The RTF document contains a table. When the document is saved and loaded from the same form, it is displaying correctly, however when loaded from a different form, it seems to have shrunk and lost the column width, thus having long and skinny columns.

We have set the fixed column width on the table, however this did not seem to solve the issue.

I have attached two screenshots for reference. One with the correct looking table, and one with the long and skinny columns.

Is there a workaround, or is this a known bug?

Correct table:

Long and skinny columns:

Currently on Telerik Winforms version 2018.3.1016.40

Kind regards,

Hi Telerik Team,

I tried to copy and past the sourcecode from one of your demo applications (not using the copy source button!). 

Unfortunaly every time I want to copy the "<" character it skips the rest of the line.

The problem occurs on different code examples.

I know there is a "Copy source" button but sometimes you just want to copy a small part.

A screenshot of an example is attached.

Hi everybody

I m try use the class CustomDragandDrop on radtreeview but i have a issue, 

if i use the next example, i dont have any problem:

   protected void BindRadTreeView()
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("Id", typeof(string));
            dt.Columns.Add("Title", typeof(string));
            dt.Columns.Add("ParentId", typeof(string));

            string parentId = string.Empty;
            string childId = string.Empty;
            for (int i = 0; i < 2; i++)
            {
                parentId = Guid.NewGuid().ToString();
                dt.Rows.Add(parentId, "Node" + i, null);
                for (int j = 0; j < 5; j++)
                {
                    childId = Guid.NewGuid().ToString();
                    dt.Rows.Add(childId, "SubNode" + i + "." + j, parentId);
                }
            }

            this.radTreeView1.ChildMember = "Id";
            this.radTreeView1.ParentMember = "ParentId";
            this.radTreeView1.DisplayMember = "Title";
            this.radTreeView1.DataSource = dt;


        }

i can drag and drop correctly

but the problem is when i binding the Radtreeview

    protected void llenatreeview1() {

            dtTablas = dat.consultaBD();

            DataTable dt = new DataTable();
            dtCopi.Columns.Add("Id", typeof(string));
            dtCopi.Columns.Add("Title", typeof(string));
            dtCopi.Columns.Add("ParentId", typeof(string));

            string parentId = string.Empty;
            string Id = string.Empty;
            string title = string.Empty;
            foreach (DataRow row in dtTablas.Rows)
            {
                parentId = row["ParentId"].ToString();     

                Id = row["Id"].ToString();
                title = row["Title"].ToString();

                if (parentId == "")
                    dt.Rows.Add(Id, title, null);
                else
                    dt.Rows.Add(Id, title, parentId);
            }

            radTreeView2.ChildMember = "Id";
            radTreeView2.ParentMember = "ParentId";
            radTreeView2.DisplayMember = "Title";
            radTreeView2.DataSource = dt;
        }

The problem, as described in the video, is that the thumb does not 'snap' to the point touched and then follow the touch as it is dragged. It is therefore difficult at times to actually 'grab' hold of the thumb unless you touch the screen in exactly the right point.

Changing the 'SnapToTicks' property purely makes the movement smoother once it is grabbed.

Dear Support,

I want to use the new feature - Support for SVG.

Then I have to load the file with RadSvgImage.FromFile().

I get the following exception:

System.Xml.XmlException: 'External DTD subset cannot be resolved - public ID =' - // W3C // DTD SVG 1.1 // EN ', system ID =' http://www.w3.org/Graphics/ SVG / 1.1 / DTD / svg11.dtd '.'

(Translated from German)

Problem is line 2, where the DTD is given.

Is there a way to tell XmlSerializer to ignore the validation?

An error occur when i used .Import method on large .pdf files (> 1000 ko) with an Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider object.

Message is:

"Impossible d'effectuer un cast d'un objet de type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfDictionary' en type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt'." 

There is no bug for smaller pdf files. 

Thank you

Hi,

I have menu problem:

When the Backstage Button Item is clicked and you don't release a left mouse button click but instead mouse is dragged to the right of the form, Backstage Button Item stay selected and can only be returned to default state if you click on it again else its stays blue and locked.

Picture 1.

Left click, hold and drag to the right. This state can be done to all buttons see Picture 2. Focus on "MouseDown" Event is not working.

Picture 2.

My question is can this behavior be prevented ?

Thanks in advance !

When the RadMap.ShowSearchBar property is set to true and the BingRestMapProvider is used, it would be nice to have autocomplete suggestion while the user is typing:

https://docs.microsoft.com/en-us/bingmaps/rest-services/autosuggest

1. Set the DPI of your main monitor to 150% and the DPI of your secondary monitor to 100%.

2. Start your main form containing RadDataEntry on your secondary monitor.

You will see that that hosted controls inside RadDataEntry are not scaled correctly.

Workaround:

Start your main form on your secondary monitor inside OnShown event.

protected override void OnShown(EventArgs e)
{
    base.OnShown(e);

    this.Location = new Point(-800, 100);
}
