When UseSystemPasswordChar  is set to true, the copy/cut from the text field must be disabled. This includes both keyboard commands (Ctrl+C and Ctrl+X) and context menu on right click.

.NET version:  .NET 7 rc-2 

Telerik UI for WinForms version: 2022.3.921

Run the attached project, right-click the button to show the context menu and then click outside the menu. You will notice that the menu remains opened.

When the HorizontalAxisStroke is not specified, an error occurs during the document's loading.

To reproduce:

1. Add a form with a RadRibbonBar and add some tabs

2. Create a second form that inherits the first one

3. Open the second form at design time and add a few items to the application menu.

Expected: either the applied changes in the derived form should be serialized properly or the ribbon in the derived form should be locked for such changed.

Actual: even though the menu items are added in the designer and you can see them, after restarting the designer, they are not shown in the application menu anymore. You can see that they are still available in the Designer.cs but they are not added to the application menu. The same behavior is observed if you add tabs and groups with different elements.

Use the sample project and follow the illustrated steps in the gif file.

Expected: when you hover a page and it has sub pages, the popup is shown automatically. When you hove another page while the popup is still opened, it shouldn't remain opened.

Actual: when you hover a page and it has sub pages, the popup is shown automatically. When you hove another page while the popup is still opened, it should be closed.

The ChartLegendElement displays the legend items in a StackLayoutElement which can be either vertical or horizontal.

        public RadForm1()
        {
            InitializeComponent();

            Random rand = new Random();
            List<LineSeries> list = new List<LineSeries>();
            for (var index = 1; index <= 15; index++)
            {
                LineSeries ls = new LineSeries();
                ls.LegendTitle = "Series " + index;
                list.Add(ls);
            }

            for (int index = 1; index <= 100; index++)
            {
                foreach (LineSeries s in list)
                    s.DataPoints.Add(new CategoricalDataPoint(index, rand.Next(0, rand.Next(5, 20))));
            }
            this.radChartView1.Series.AddRange(list.ToArray());
            this.radChartView1.ShowLegend = true;
            this.radChartView1.ChartElement.LegendPosition = LegendPosition.Bottom;
            this.radChartView1.ChartElement.LegendElement.StackElement.Orientation = Orientation.Vertical;
        }

Horizontal:

Vertical:

It would be good to provide an option for wrapping the legend items:

Workaround: use an appropriate container for the legend items to wrap the legend item and use the space more efficiently

The method GridViewTemplate.SetError creates in most situations an GridViewDataErrorEventArgs object twice.

Current code:

GridViewDataErrorEventArgs args = new GridViewDataErrorEventArgs(exception, 0, 0, GridViewDataErrorContexts.Commit);
if (e != null)
{
    args = new GridViewDataErrorEventArgs(exception, e.ColumnIndex, e.RowIndex, GridViewDataErrorContexts.Commit);
}

In assume in most cases e will not be null, so in must cases the first args will be removed. This has a small negative impact on memory and performace.

Suggestion:

GridViewDataErrorEventArgs args = e == null 
    ? new GridViewDataErrorEventArgs(exception, 0, 0, GridViewDataErrorContexts.Commit)
    : new GridViewDataErrorEventArgs(exception, e.ColumnIndex, e.RowIndex, GridViewDataErrorContexts.Commit);

This is about the following method:

        public void SetError(GridViewCellCancelEventArgs e, Exception exception)
        {
            GridViewDataErrorEventArgs args = new GridViewDataErrorEventArgs(exception, 0, 0, GridViewDataErrorContexts.Commit);
            if (e != null)
            {
                args = new GridViewDataErrorEventArgs(exception, e.ColumnIndex, e.RowIndex, GridViewDataErrorContexts.Commit);
            }
            this.EventDispatcher.RaiseEvent<GridViewDataErrorEventArgs>(EventDispatcher.DataError, this, args);

            if (args.ThrowException)
            {
                throw args.Exception;
            }

            if (args.Cancel)
            {
                //TODO: cancel row edit 
            }
        }

Right now, the method GridViewTemplate.SetError accepts a parameter of type GridViewCellCancelEventArgs, which in itself is weird, because event args should only be used inside events and OnXXX-methods. But since SetError fires an event, one could argue that this method is like a OnXXX-method.

But inside it becomes more weird, it translates GridViewCellCancelEventArgs into GridViewDataErrorEventArgs. And I must admit, the last DataError-args feel a lot more logical that CellCancel-args when firing setting an error. Furthermore, if I create an override of class GridViewCellCancelEventArgs to contain more data about an error, this information never reaches the event handlers.

So why this translation? Or better: Why this parameter?

My suggestion would be to make a new overload:

public void SetError(GridViewDataErrorEventArgs e)
{
    if (e == null)
        throw new ArgumentNullException(nameof(e));

        this.EventDispatcher.RaiseEvent<GridViewDataErrorEventArgs>(EventDispatcher.DataError, this, args);

        if (args.ThrowException)
                throw args.Exception;

        if (args.Cancel)
        {
                // TODO: I really do not know what telerik wanted to do here, so I live this up to Telerik.
        }
}

Add a RadSpellChecker, a MS TextBox and a MS RichTextBox to the form. Try to set the AutoSpellCheckControl to RichTextBox, but the control is missing in the drop down:

"http://" prefix is automatically added by the Insert Hyperlink Dialog when the provided URI is to local path or mapped drive, e.g. "Z:\temp".

Workaround 1: Set HyperlinkPattern to something that matches file paths, e.g.:
(this.radRichTextEditor1.RichTextBoxElement.InsertHyperlinkDialog as InsertHyperlinkDialog).HyperlinkPattern = ".*";

Workaround 2: Insert such paths with the "file://" prefix.

Follow the steps:

1- Add RadRibbonBar1 to the form. The program compiles successfully.
2- Add RibbonTab1 to the RibbonBar. The program compiles successfully.
3. Add RadRibbonBarGroup1. The program does not compile and the mentioned error appears.

Repro-steps

1. Create a Form
2. Add a RadGridView control
3. Add two Text columns
4. Run the form
5. Add a new row to the RadGridView with values "a" and "b"
6. Add a another row to the RadGridView with values "c" and "d"
7. Select the first row and copy the row values
8. Select the first cell of the second row and paste the values

Expected behavior

• The values "a" and "b" are in the second row

Observed behavior

• The values "ab" and "d" are in the second row

Repro-steps

1. Create a Form
2. Add a RadGridView control
3. Add two Text columns
4. Run the form
5. Add a new row to the RadGridView with values "a" and "b"
6. In Excel fill a row with two cells with values "c" and "d"
7. Select those cells and copy them to the clipboard
8. In the RadGridView select the first cell of the row
9. Paste the data

Expected behavior

• The values "c" and "d" are in the row

Observed behavior

• The values "System.IO.MemoryStream" and "b" are in the row

Extra info

If the first column is of another type (like GridViewDecimalColumn) a DataError occurs (because "System.IO.MemoryStream" cannot be parces to a decimal).

Please refer to the attached sample project. Try to select a point.

Expected result: the clicked point should be colored in red.

Actual result: a random point is colored in red even though the label is colored correctly. The attached gif file illustrates the observed result.

Searching for a workaround for a previously reported bug, in walked into a little thing:

private void SelectAllCells()
    {
      GridViewRowInfoEnumerator rowInfoEnumerator = new GridViewRowInfoEnumerator((IHierarchicalRow) this.GridViewElement.Template);
      List<GridViewCellInfo> gridViewCellInfoList = new List<GridViewCellInfo>();
      this.MasterTemplate.SelectedCells.BeginUpdate();
      this.MasterTemplate.SelectedCells.Clear();
      while (rowInfoEnumerator.MoveNext())
      {
        GridViewRowInfo current = rowInfoEnumerator.Current;
        if (current.CanBeSelected)
        {
          foreach (GridViewCellInfo cell in current.Cells)
            this.MasterTemplate.SelectedCells.Add(cell);
        }
      }
      this.MasterTemplate.SelectedCells.EndUpdate(true);
    }
