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. 

Use attached to reproduce. 

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. 

Caret jumps several symbols to the right when arabic or persian is used and user deletes the dot symbol. As a result the wrong symbol is deleted.

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

To reproduce:

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

The performance of the DayView when the control is bound to a large number of recurring appointments and it is grouped by resources needs to be improved.

Use attached to reproduce.

AutoCompleteSuggestHelper, Assembly: Telerik.WinControls.UI, Version=2019.1.117.40

 

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);
      }
    }

 

See the attached screenshot

To reproduce:

Copy an image and paste is several times inside the document.

To reproduce:

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

- Nothing happens and only the current sheet is printed

Workaround:

private void RadDropDownButton1_DropDownOpening(object sender, EventArgs e)
{
    var args = e as RadPopupOpeningEventArgs;
    var popupSize = radDropDownButton1.DropDownButtonElement.DropDownMenu.Size;
    var x = args.CustomLocation.X - (popupSize.Width - radDropDownButton1.Width);
    args.CustomLocation = new Point(x, args.CustomLocation.Y);
}

The new series will be similar to the RadarColumnSeries which is already available. https://docs.telerik.com/devtools/aspnet-ajax/controls/htmlchart/chart-types/polar-chart

Steps to reproduce:

1) Add a RadForm with 3 buttons. Apply Fluent Theme to all.

2) In the click handler of the first two buttons, set enable to false for the button that was clicked. Third button, do nothing.

3) Run app. Click all 3 buttons.

 

Desired Result:

Focus indicator should be hidden for previous-focused but now-disabled controls.

 

Actual Result:

Blue Fluent focus-indicator border is still showing (my user's are confused and complaining), see attachment.

[May happen on other themes too, didn't check.]

 

Had to implement a work-around...

 

Work around: 

Set border element to off for every programmatically disabled control: this.radButton1.ButtonElement.BorderElement.Visibility = ElementVisibility.Hidden;

The functionality should be similar to the one in RadRibbonBar: https://docs.telerik.com/devtools/winforms/controls/ribbonbar/designing-radribbonbar/adding-key-tips

 Hi. I try to resolve the problem as u describe but Still having the same error msg Any other solution

Check the attached video 

or:

1. Insert some text

2. Change its span properties (e.g. set the font weight to Bold)

3. Position the caret right after the last letter of this text and type several letters

Observed: The span properties are applied to the new text as well

Expected: The new text shouldn't have those properties

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

Add Office 2016 theme to the WinForms suite.
