Workaround:

If possible set the Dock property to Fill.

How to reproduce:

LineSeries lineSeries = new LineSeries();
lineSeries.DataPoints.Add(new CategoricalDataPoint(6, "Harley"));
lineSeries.DataPoints.Add(new CategoricalDataPoint(4, "White"));
lineSeries.DataPoints.Add(new CategoricalDataPoint(7, "Smith"));
lineSeries.DataPoints.Add(new CategoricalDataPoint(5, "Jones"));
lineSeries.DataPoints.Add(new CategoricalDataPoint(3, "Marshall"));
lineSeries.DataPoints.Add(new CategoricalDataPoint(8, "Stevens"));
lineSeries.DataPoints.Add(new CategoricalDataPoint(7, "Brown"));
lineSeries.DataPoints.Add(new CategoricalDataPoint(10, "Carter"));
lineSeries.DataPoints.Add(new CategoricalDataPoint(4, "Bryant"));
lineSeries.DataPoints.Add(new CategoricalDataPoint(5, "Mora"));
lineSeries.DataPoints.Add(new CategoricalDataPoint(2, "Roy"));

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

//setup plot band
CartesianPlotBandAnnotation annotation1 = new CartesianPlotBandAnnotation();
annotation1.Axis = this.radChartView1.Axes[0] as CartesianAxis;
annotation1.From = "Bryant";
annotation1.To = "Mora";
annotation1.BackColor = Color.FromArgb(100, Color.LightBlue);
annotation1.BorderColor = Color.Black;
annotation1.BorderWidth = 1;
this.radChartView1.Annotations.Add(annotation1);

AxisScaleBreak scaleBreakItem = new AxisScaleBreak();
scaleBreakItem.Name = "Item1";
scaleBreakItem.From = "Smith";
scaleBreakItem.To = "Brown";

horizontalAxis.ScaleBreakSize = 50;
horizontalAxis.ScaleBreaks.Add(scaleBreakItem);

An exception is thrown inside TableSearchRow_SearchProgressChanged event. GridSearchResultCellCollection Cells value is null.

Please note that issue firstly occurs in version 2018.3.116.

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!");
    }
}

Currently, the event arguments do not expose the data item.

The issue can be reproduced on a touch device after performing zoom in and zoom out

ChartPanZoomController panZoomController = new ChartPanZoomController();
panZoomController.PanZoomMode = ChartPanZoomMode.Both;
this.radChartView1.Controllers.Add(panZoomController);

 

When there are no data rows in the grid the new row is current and the message is not displayed. In some themes, the grid looks like there is a single row which is confusing to the end users. 

Workaround: 

ArgumentNullExceptionn in the RadPropertyValuesCollection class.

Currently, the DashStyle cannot be changed.

The issue can be reproduced by setting the AssociatedControl property in the designer and later at run-time.

Use attached to reproduce (the orientation must be set at design time)

Workaround:

Set it in code:

commandBarToggleButton2.Orientation = Orientation.Vertical

Workaround: additionally call the Select method of the text box element

Private Sub RadPageView1_SelectedPageChanged(sender As Object, e As EventArgs)
    If Me.RadPageView1.SelectedPage Is Me.RadPageViewPage1 Then
        Me.RadTextBoxControl1.Select()
        Me.RadTextBoxControl1.TextBoxElement.Select(0, 0)
    End If
End Sub

Other themes are also missing the IsSelected state, the fix should also handle them.

The issue can be observed in themes having shadows:

- Material 

- Fluent

To reproduce:

-double click an option in the MultiColumnCombobox editor and close the editor in the selected index changed event.

I need to tab though the form fields in RadPdfViewer instead of having to click in each one

To reproduce: 

-Open the FileExplorer example. 

- Resize the panel (see attached).

This will handle the scenario of having different image sets for different DPI.

Isnt the hilighted line (contains branch) very unoptimized.

https://rhale78.wordpress.com/2011/05/16/string-equality-and-performance-in-c/

Multiple ToLower string operation. Why not let the framework do the operation since you are always using ordinal?

optimized version: return item.Text.Contains(this.Filter, StringComparison.OrdinalIgnoreCase);

 

protected virtual bool DefaultFilter(RadListDataItem item)
    {
      switch (this.suggestMode)
      {
        case SuggestMode.StartWiths:
          return item.Text.StartsWith(this.Filter, this.StringComparison);
        case SuggestMode.Contains:
          if ((this.StringComparison & StringComparison.InvariantCultureIgnoreCase) == StringComparison.InvariantCultureIgnoreCase || (this.StringComparison & StringComparison.InvariantCultureIgnoreCase) == StringComparison.CurrentCultureIgnoreCase)
            return item.Text.ToLower().Contains(this.Filter.ToLower());
          return item.Text.Contains(this.Filter);
        default:
          return item.Text.StartsWith(this.Filter, this.StringComparison);
      }
    }
