It would be very convenient to scroll to a specific message when a lot of messages are available.

Release R3 2019

Please refer to the attached sample project and follow the steps from the gif file. The scrollbar needs to be in the middle.

Note: the issue can be reproduced without action list as well.

Release R3 2019

 The scroll in the SuggestedActionsElement cannot be made visible, one can scroll only with the mouse. Introduce a property so there is an indication that additional items are available.

In addition, the CreateChatElement in RadChat class should be made virtual.

When trying to import a document containing bookmark and BookmarkRangeEnd is after the last paragraph, a StackOverflowException is thrown in IntervalNode while trying to rebuild the document cache. (RadDocumentChildrenCache.RebuildTree()).

The same could be observed if the bookmark end is last in the header/footer, between table cells in the RadDocument body, or when all paragraphs after the bookmark range end are hidden (with vanish property).

Workaround: Detect the problematic annotations and remove them:
foreach (var rangeStart in document.EnumerateChildrenOfType<AnnotationRangeStart>())
{
    if (rangeStart.End == null || rangeStart.End.Parent == null || rangeStart.End.Parent.Parent == null)
    {
        //MessageBox.Show("This indicates a problem.");
        rangeStart.Parent.Children.Remove(rangeStart);
    }
}

Note: Until 2017 R2 SP1 release StackOverflowException is thrown, after this release an ArgumentException should be thrown.

Hi,

 

I am working with the RadGridView in my c# winform application. I am using the custom font ("Font Awesome 5 Free Solid") for the RadGridView using the "CellFormatting" event to view the icons along with the text. Here i am able to see the proper icons with text but when i open the filter menu to filter out the rows, i am unable to see the icons (icons shown as the box) as in filterbox we don't have any custom font

I tried to working out the properties of the RadTreeNodeCollection but here we dont have any Custom font property for the same. 

i want to show the text as it is in the filterbox along with the text and the icon.

so can you suggest what i can do to view the icons in the filterbox?

Check the attachment for reference.

To reproduce: run the attached project and toggle the checkbox in the header cell of the child template. 

Workaround: use a custom GridCheckBoxHeaderCellElement

02.{
03.    if (!IsFormOpen(typeof(frmSupplierList)))
04.    {
05.        CloseChildForm();
06.        frmSupplierList m_frmListSupplier = new frmSupplierList
07.        {
08.            Width = this.Width,
09.            Height = this.Height,
10.            MdiParent = this,
11.            MaximizeBox = false,
12.            MinimizeBox = false,
13.            ControlBox = false,
14.            WindowState = FormWindowState.Maximized
15.        };
16.        m_frmListSupplier.Show();
17.    }
18.}

 

But Still i can see the ControlBox and Minimize and Maximize Buttons on the Top right Corner. 

Image Attached.

When i Use the Same Coding and Properties using Standard Windows Forms. It behave like as required.

By default, if you need to format the cells in RadCalendar, the ElementRender event is an appropriate solution. However, it doesn't process the row/column header cell elements illustrated in the attached screenshot.

Workaround:

            MonthViewElement mve = (MonthViewElement)this.radCalendar1.CalendarElement.CalendarVisualElement;
            foreach (CalendarCellElement cell in mve.TableElement.Children)
            {
                if (cell.Row == 0)
                {
                    cell.DrawFill = true;
                    cell.BackColor = Color.Red;
                } 
            }

Please refer to the attached sample project and run it. Select a random item and press the button. You will obtain the error. If no selection is available, the item is removed as expected. 

Workaround: use Begin/EndUpdate block while deleting a record from the DataTable:

        Me.RadGanttView1.BeginUpdate()
        _dataset.Tables("Tasks").Rows.RemoveAt(2)
        Me.RadGanttView1.EndUpdate()

The FulentDarkTheme sets a transparent background which results in a slow resizing. 

Workaround:

this.TabbedFormControl.RootElement.BackColor = Color.Black;

Changing the preferred width of columns to percentages from the Table Properties dialog actually sets them in pixels.

Steps to reproduce:
1) Insert a table

2) select table column property and set preferred width to 20%

3) press "next column" button and set preferred width to 20% 

4) Go to previous columns 

Expected: Column width is set in percentage.

Actual: Some (or all) columns have width set in pixels.

Dear Sir/Madam,

 

I have a docx document and want to display it in flow layoutmode. It works normally except it cannot show header at the beginning of the document and footer at the end of the document. Please help.

My code is similar as follows (Rte is the RadRichTextEditor control):

 

DocumentFormatProviderBase provider = new DocxFormatProvider();

Rte.SuspendLayout();

Rte.Document = provider.Import([Docx in byte array]);

Rte.RichTextBoxElement.BackColor = Color.White;

Telerik.WinControls.RichTextEditor.UI.DocumentWebLayoutPresenter presenter = (Telerik.WinControls.RichTextEditor.UI.DocumentWebLayoutPresenter)rte.RichTextBoxElement.ActiveEditorPresenter;

presenter.BackColor = Color.White;

presenter.Margin = new Padding(20);

Rte.ResumeLayout();

Rte.PerformLayout();

1. Add a pin to the map.
radMap1.Layers.Add(new MapLayer("PinLayer"));
MapPin pin = new MapPin(new Telerik.WinControls.UI.Map.PointG(47.60357, -122.32945));
pin.BackColor = Color.Red;
radMap1.Layers[0].Add(pin);
2. Run the project and zoom out.
3. Resize vertically the map(form).

Workaround:
Call Pan method to recalculate RadMapElement.ViewportInPixels on SizeChanged. 
private void RadMap1_SizeChanged(object sender, EventArgs e)
{

If I set .InitialDirectory to a network path, the Tree Navigation Pane shows multiple instances of the network path. I've collapsed several of them so you can see it more easily in the image. Am I missing a setting? Can this be prevented in the Directory Requesting sub?

Maybe I'm doing this wrong but it works with the standard .Net SaveFileDialog. No matter how many filters I add or which FilterIndex I set, the last filter is always activated.

With DF.RadSaveFileDialog1
    .SaveFileDialogForm.StartPosition = FormStartPosition.CenterParent
    .SaveFileDialogForm.Text = "Save File As - " & DF.OriginalTitle
    .SaveFileDialogForm.ThemeName = "Fluent"
    .CustomPlaces.Clear()
    .ShowNetworkLocations = False

    .Filter = "Word Document (*.docx)|*.docx|PDF Document (*.pdf)|*.pdf"
    .RestoreDirectory = True
    .FilterIndex = 1
    .ShowDialog()
