One should not be able to use the ribbon bar buttons when a protected document is opened or the rich text editor is read-only. 

Use attached to reproduce. 

The whole cell is not filled when setting the background.

Using the RadDocumentEditor class, the users can change the margin of the current section. However, there isn't a method allowing them to change the default section margin of the document. 

When the current SpanLayoutBox is split (for example by inserting space), the DocumentPosition created with trackDocumentChangeEvents option (with some of the constructor accepting the boolean 'trackDocumentChangeEvents' parameter) jumps back with two symbols.

LineSeries lineSeries = new LineSeries();
lineSeries.DataPoints.Add(new CategoricalDataPoint(6, DateTime.Now));
lineSeries.DataPoints.Add(new CategoricalDataPoint(4, DateTime.Now.AddDays(1)));
lineSeries.DataPoints.Add(new CategoricalDataPoint(7, DateTime.Now.AddDays(2)));
lineSeries.DataPoints.Add(new CategoricalDataPoint(5, DateTime.Now.AddDays(3)));
lineSeries.DataPoints.Add(new CategoricalDataPoint(3, DateTime.Now.AddDays(4)));
lineSeries.DataPoints.Add(new CategoricalDataPoint(8, DateTime.Now.AddDays(5)));
lineSeries.DataPoints.Add(new CategoricalDataPoint(7, DateTime.Now.AddDays(6)));
lineSeries.DataPoints.Add(new CategoricalDataPoint(10, DateTime.Now.AddDays(7)));
lineSeries.DataPoints.Add(new CategoricalDataPoint(4, DateTime.Now.AddDays(8)));
lineSeries.DataPoints.Add(new CategoricalDataPoint(5, DateTime.Now.AddDays(9)));
lineSeries.DataPoints.Add(new CategoricalDataPoint(2, DateTime.Now.AddDays(10)));

DateTimeContinuousAxis continuousAxis = new DateTimeContinuousAxis();
continuousAxis.PlotMode = AxisPlotMode.OnTicks;
continuousAxis.LabelFormat = "{0:d}";
continuousAxis.ScaleBreakStyle = ScaleBreakStyle.Ragged;
lineSeries.HorizontalAxis = continuousAxis;
this.radChartView1.Series.Add(lineSeries);

DateTimeContinuousAxis horizontalAxis = radChartView1.Axes.Get<DateTimeContinuousAxis>(0);

AxisScaleBreak scaleBreakItem = new AxisScaleBreak();
scaleBreakItem.Name = "Item1";
scaleBreakItem.From = DateTime.Now.AddDays(3);
scaleBreakItem.To = DateTime.Now.AddDays(6);

Use attached to reproduce:

1. Click the button

2. Change the tab and go back to the diagram

Workaround:

Add the layout before showing the form

When one performs a pan operation the axis minimum and maximum should be automatically adjusted. See https://www.okex.com/market?product=btt_usdt

To reproduce:

- Open The popup

- Click on it, and then click on the form

- Repeat until the popup stays opened

Hi,

 

It would be cool if we had a Material Dark Theme,

More and more we see clients requesting this from our apps since Google has popularized the trend now.

 

Thanks

To reproduce: please refer to the attached sample project and gif file.

Workaround: use screentips: https://docs.telerik.com/devtools/winforms/telerik-presentation-framework/tooltips-and-screentips/screen-tips

To reproduce:
- Drag RadDropDownList control on a form, expand its DropDownListElement property, and change the ItemHeight
- Another case is, on a RadForm, expand FormElement>TitleBarElement and set its Visibility to Collapsed

Workaround: set the desired property at runtime
radDropDownList1.DropDownListElement.ItemHeight = 22;

Steps to reproduce:
1. Drag a grid on the form
2. Drag one or more controls over the grid - at this point in the Document Outline you can see the dragged control is a child of the grid
3. Open the Property Builder of the grid and close it - at this point the dragged control disappears

Workaround:
1. Open the Designer.cs file, and locate the line, where the control is added to the grid e.g.
            this.radGridView2.Controls.Add(this.radButton4);
and change it to:
            this.Controls.Add(this.radButton4);

If need be, set the Location property of the control at design time, to position it at the desired place.

2. Alternatively, you can place the control outside the grid bounds and after selecting it, use the arrow keys to position is over the grid. This will not make it its child, hence the issue will not appear.

We want to have full access to the 1920x1080 cameras at max FPS in the preview stream. But when we record, we'd like to record the video at smaller resolution (720p) and a lower FPS, ~30 or so we could use something like FFMPEG to resize post recording, but we'd rather not have to do that extra processing.

Currently the sgen tool raises an exception when executing it on RadControls and RadControls.UI. There is also an XmlSerialization exception when  loading the application.

When a developer set the RadForm.ThemeName property and then drag any controls onto the form, they will get automatically this theme applied to the control's ThemeName property. However, if you already have some controls on the form with ThemeName = "X" and you change RadForm.ThemeName to "Y", all controls' ThemeName should be changed to the new RadForm.ThemeName as well.

How to reproduce: 
1. Use the following code to change the default style of the document:
StyleDefinition h2 = this.radRichTextBox.Document.Style;
h2.SpanProperties.FontFamily = new System.Windows.Media.FontFamily("Microsoft Sans Serif");
h2.SpanProperties.FontSize = Unit.PointToDip(8.25f);
h2.ParagraphProperties.SpacingAfter = 0;

h2 = radRichTextBox.Document.Style;
h2.SpanProperties.FontFamily = new System.Windows.Media.FontFamily("Microsoft Sans Serif");
h2.SpanProperties.FontSize = Unit.PointToDip(8.25f);
h2.ParagraphProperties.SpacingAfter = 0;

StyleDefinition hyperlinkStyle = this.radRichTextBox.Document.StyleRepository["Hyperlink"];
hyperlinkStyle.SpanProperties.FontFamily = new System.Windows.Media.FontFamily("Microsoft Sans Serif");
hyperlinkStyle.SpanProperties.FontSize = Unit.PointToDip(8.25f);

2. Add some text to the document

3. Add a hyperlink somewhere in the middle of the text

4. Start moving the caret so it moves over the hyperlink start

Observed: When on hyperlink start/end, the caret is with bigger size than the content

Expected: The caret should be with the size of the content

Currently, RadGridView offers GridViewImageColumn. However, it would be good to offer support for SVG images out of the box.  

One possible approach is to introduce a new property for the GridViewImageColumn - ImageDrawType = ImageDrawType.Svg that controls what kind of images this column will store.

Second approach is to introduce a new GridViewSvgImageColumn.

I would like to have a generic validation-mechanism, implemented in all controls. Hear me out:

A class ValidationInformation for containing all sort of validation information for a certain field, property, cell, etc. which has properties likes:

• Type DataType
• object MinValue
• object MaxValue
• int? MinLength
• int? MaxLength
• bool IsRequired
• RegEx Mask
• etc.

It also has a virtual method like bool Validate(object entity, object value, out string validationError).

A base class ValidationInformationProvider for retrieving validation information from various sources. It has some abstract methods for retrieval, storing/caching information per cell/field/property.

This base class has the following subclasses:

• ValidationInformationProviderFromDataTable
• ValidationInformationProviderFromAnnotations
• ValidationInformationProviderFromXXX

Each provider is responsible for reading validation information from the source (DataTable, annotations on a property, etc.) and fill a ValidationInformation object.

Now the fun begins...

Each Telerik class, like RadGridView and/or subcomponents should get a method or event to retrieve ValidationInformation. When the event is not handled or the method returns null, the default behavior kicks in.

When ValidationInformation is provided, default behavior is overridden. Properties of editors van be set with values from ValidationInformation (like Minimum and Maximum of a GridViewDecimalColumnPlus or RadSpinEditorElement). At the end if editing the method ValidationInformation.Validate is called to validate the new value. The validation error can be used for popups, or tooltips, or an exception. 

This way a user does not have to think where to set which property of any Telerik control for any validation. This way a RadPropertyGrid and RadGridView can work the same way when it comes to data validation, regardless of all editors which work in the background.
