Sorting problem with RadCartesianChart with live updates

I'm working with the RadCartesianChart and using a BarSeries. In the series I have values that change, items that ger removed, and items that get added. I'd like for them to be sorted. I think I am implementing it correctly but could be mistaken. When the chart updates it displays values that are not sorted

I have attached a demo project to this post. I am using version 2024.2.514. Please let me know if there is anything I need to change or if I'm doing something incorrect.

Thank You,

Giuliano

Updating Table Cell In code Locks the Table

Hi,

When I update a table cell in a richtextbox the table is locked and I am unable to edit the table in the UI. The change to the table cell is not shown in the

UI If I then close the current document and re-open it its fine and I can see the change made to the table cell, or if I make a change to a paragraph above the table from within the UI the change to the cell is shown, and the table is unlocked.

        public void SetTemplateFromElement(string tagValue, string newValue)
        {
            try
            {
//                RadDocument document = doc_text.Document;
                var table = doc_text.Document.EnumerateChildrenOfType<Table>().Where(x => x.Tag == tagValue).FirstOrDefault();
                if (table != null)
                {

                    switch (tagValue)
                    {
                        case "1000":
                            var row = table.EnumerateChildrenOfType<TableRow>().FirstOrDefault();
                            var cell = row.Cells.ToList()[1];
                            cell.Blocks.Clear();
                            Paragraph p = new Paragraph();
                            Span s = new Span();
                            s.FontWeight = FontWeights.Bold;
                            s.FontFamily = new FontFamily(CGlobals.docu_default_font);
                            s.FontSize = Unit.PointToDip(CGlobals.docu_default_font_size);
                            s.Text = newValue; ;
                            p.Inlines.Add(s);
                            cell.Blocks.Add(p);
                            break;
                        case "4000":
                            break;
                    }

                    //                    doc_text.Document = document;
                    doc_text.UpdateLayout();
                    SaveContent(strCurrentDoc);
                }
            }
            catch { }

        }

Can someone please advise.

How to add bullets to TableCell in code

Hi,

I need to add bullets to a TableCell from code. I have tried cell.Blocks.Add(bullets) where bullets is a DocumentList but I am getting 'cannot convert from DocumentList to Block.

Code snippet:

                            DocumentList bullets = new DocumentList(DefaultListStyles.Bulleted, document);
                            p1 = new Paragraph();
                            s1 = new Span();
                            cell1.Background = Color.FromRgb(255, 255, 255);
                            cell1.PreferredWidth = w1;
                            cell1.Padding = new Telerik.Windows.Documents.Layout.Padding(3, 6, 3, 6);
                            s1.FontFamily = new FontFamily(CGlobals.docu_default_font);
                            s1.FontSize = Unit.PointToDip(CGlobals.docu_default_font_size);
                            s1.Text = name;
                            p1.Inlines.Add(s1);
                            bullets.AddParagraph(p1);
                            cell1.Blocks.Add(bullets);

Thank you

RadScheduleView GetVisibleRangeStart/end in MVVM

Hi,

I would like to retrieve the VisibleRangeStart and VisibleRangeEnd properties after a VisibleRangeChanged event occurs.

How can I do that in mvvm?

I can track the changed event with:

<telerik:EventToCommandBehavior.EventBindings>
<telerik:EventBinding Command="{Binding CustomCommand}" EventName="VisibleRangeChanged" />
</telerik:EventToCommandBehavior.EventBindings>

Thanks in advance,
Egbert

DocumentVariableFields Make Read Only and Click Event

A couple of questions regarding DocumentVariableFields:

1. Is it possible to make a field read only, i.e. the field cannot be deleted from the UI.

I'm inserting the field into a table cell:

            RadDocumentEditor editor = new RadDocumentEditor(document);
            var cell = document.EnumerateChildrenOfType<TableCell>().ToList()[0];

            if (cell != null)
            {
                DocumentPosition position = new DocumentPosition(document);
                position.MoveToDocumentElementStart(cell.Blocks.First());
                document.CaretPosition.MoveToPosition(position);
                DocumentVariableField docVariable = new DocumentVariableField() { VariableName = "2000" };
                editor.InsertField(docVariable);
            }
            doc_text.Document = document;

            doc_text.Document.DocumentVariables["2000"] = "Date";
            //doc_text.Document.DocumentVariables["2002"] = " ";
            var field = doc_text.Document.EnumerateChildrenOfType<FieldRangeStart>().Where(x => x.Field.FieldTypeName == "DOCVARIABLE"
            && ((DocumentVariableField)x.Field).VariableName == "2000").FirstOrDefault();

            if (field != null)
            {
                doc_text.UpdateField(field);
            }
