Change the border color in individual cells in Spire.PDF grid C#

I am using Spire.PDF library to create a PDF in server side and return it to mobile side. Everything is working great. But I wanna access to each cell's border in the grid. I wanna change the color of the border.

What I get from this...
What I want...
I tried to do this, but it didn't work.
row0.Cells[0].Style.Borders.Right.Color = Color.DarkRed;
row1.Cells[0].Style.Borders.Right.Color = Color.DarkRed;
row2.Cells[0].Style.Borders.Right.Color = Color.DarkRed;
row3.Cells[0].Style.Borders.Right.Color = Color.DarkRed;

Try the below code:
float gridHeight = 20.0f;
for (int i = 0; i < grid.Rows.Count; i++)
{
grid.Rows[i].Height = gridHeight;
grid.Rows[i].Cells[0].Style.Borders.Right = new PdfPen(PdfBrushes.DarkRed);
grid.Rows[i].Cells[1].Style.Borders.Left = new PdfPen(PdfBrushes.DarkRed);

Moving a group of elements on Canvas

I want to draw a signal image as shown below at runtime on canvas.
sample code which I used to draw this signal is as below.
Ellipse Ellipse1 = new Ellipse();
Ellipse Ellipse2 = new Ellipse();
Ellipse Ellipse3 = new Ellipse();
Line lineV = new Line();
Line lineH = new Line();
lineV.Stroke = SystemColors.WindowFrameBrush;
lineV.X1 = EndPosition.X;
lineV.Y1 = EndPosition.Y;
lineV.X2 = StartPosition.X;
lineV.Y2 = EndPosition.Y;
SolidColorBrush redBrush = new SolidColorBrush();
redBrush.Color = Colors.Black;
lineV.StrokeThickness = 2;
lineV.Stroke = redBrush;
canvas1.Children.Add(lineV);
lineH.Stroke = SystemColors.WindowFrameBrush;
lineH.X1 = StartPosition.X;
lineH.Y1 = EndPosition.Y;
lineH.X2 = StartPosition.X;
lineH.Y2 = StartPosition.Y;
redBrush.Color = Colors.Black;
lineH.StrokeThickness = 2;
lineH.Stroke = redBrush;
canvas1.Children.Add(lineH);
SolidColorBrush mySolidColorBrush1 = new SolidColorBrush();
mySolidColorBrush1.Color = Colors.Red; //FromArgb(255, 255, 255, 0);
Ellipse1.Fill = mySolidColorBrush1;
Ellipse1.StrokeThickness = 2;
Ellipse1.Stroke = Brushes.Black;
Ellipse1.Width = 30;
Ellipse1.Height = 30;
Ellipse1.Margin = new Thickness(EndPosition.X, EndPosition.Y - 15, EndPosition.X + 50, EndPosition.Y + 50);
canvas1.Children.Add(Ellipse1);
SolidColorBrush mySolidColorBrush2 = new SolidColorBrush();
mySolidColorBrush2.Color = Colors.Green; //FromArgb(255, 255, 255, 0);
Ellipse2.Fill = mySolidColorBrush2;
Ellipse2.StrokeThickness = 2;
Ellipse2.Stroke = Brushes.Black;
Ellipse2.Width = 30;
Ellipse2.Height = 30;
Ellipse2.Margin = new Thickness(EndPosition.X + 30, EndPosition.Y - 15, EndPosition.X + 60, EndPosition.Y + 50);
canvas1.Children.Add(Ellipse2);
SolidColorBrush mySolidColorBrush3 = new SolidColorBrush();
mySolidColorBrush3.Color = Colors.Yellow; // FromArgb(255, 255, 255, 0);
Ellipse3.Fill = mySolidColorBrush3;
Ellipse3.StrokeThickness = 2;
Ellipse3.Stroke = Brushes.Black;
Ellipse3.Width = 30;
Ellipse3.Height = 30;
Ellipse3.Margin = new Thickness(EndPosition.X + 60, EndPosition.Y - 15, EndPosition.X + 150, EndPosition.Y + 50);
canvas1.Children.Add(Ellipse3);
**Now I want the user to be able to interactively move this signal on the canvas on mouse move events.
How can I able to do this ?**
Iam using C# WPF.

If want to implement a canvas to drag elements, a DragCanvas is your choice.
Dragging Elements in a Canvas from Josh Smith and after Dragging Elements in a Canvas from igkutikov that adapt Josh Smith code. There are articles with #mustread category.
With the dragCanvas you can implement a full functionality Dragging Element Canvas, and better adapt to your code. Happy coding!

Chart without Axis Lines

I'm trying to create chart programmatically. Here is code
static void Main(string[] args)
{
var xvals = new[]
{
new DateTime(2012, 4, 4),
new DateTime(2012, 4, 5),
new DateTime(2012, 4, 6),
new DateTime(2012, 4, 7)
};
var yvals = new[] { 1, 3, 7, 12 };
// create the chart
var chart = new Chart();
chart.Width = 600;
chart.Height = 350;
var chartArea = new ChartArea();
chartArea.AxisX.IsMarginVisible = false;
chartArea.AxisY.IsMarginVisible = false;
chartArea.AxisX.LabelStyle.Format = "dd";
chartArea.AxisX.MajorGrid.LineWidth = 0;
chartArea.AxisY.MajorGrid.LineWidth = 0;
chartArea.AxisY.LabelStyle.Font = new Font("Consolas", 8);
chartArea.AxisX.LabelStyle.Font = new Font("Consolas", 8);
chart.ChartAreas.Add(chartArea);
var series = new Series();
series.Name = "Series1";
series.ChartType = SeriesChartType.Line;
chart.Series.Add(series);
chart.Series["Series1"].Points.DataBindXY(xvals, yvals);
chart.SaveImage("chart.png", ChartImageFormat.Png);
}
I'm getting following output,
How can I remove Axis Lines both X and Y? So that my output will only the blue line.

chartArea.AxisY.LineWidth = 0;
chartArea.AxisX.LineWidth = 0;
chartArea.AxisX.LabelStyle.Enabled = false;
chartArea.AxisY.LabelStyle.Enabled = false;
chartArea.AxisX.MajorTickMark.Enabled = false;
chartArea.AxisY.MajorTickMark.Enabled = false;
Fixed my problem

Connect two UIElement with Arc

I have two UIElements(i.e. rectangles) in Canvas and their coordinates. How can I connect them with arc in code behind?

No need to get an exact hit on the rectangles (or other objects): make sure the Z ordering is correct. arc.SetValue(Canvas.ZIndex, -1) will push it to the background. If you want a perpendicular hit, you'll need to break out the algebra :/
For the arc: (see http://msdn.microsoft.com/en-us/library/ms751808.aspx), it needs to be contained in a PathFigure.
Edit: this shows two connected rectangles. The line simple runs between the two centers. The arc starts on one center (the pathFigure startpoint), first argument is the center of the second object.
r1 = new Rectangle();
r1.Margin = new Thickness(50, 50, 0, 0);
r1.VerticalAlignment = System.Windows.VerticalAlignment.Top;
r1.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
r1.Height = 50;
r1.Width= 50;
r1.Fill = new SolidColorBrush(Colors.Red);
r2 = new Rectangle();
r2.Width = 50;
r2.Height = 50;
r2.Fill = new SolidColorBrush(Colors.Blue);
r2.Margin = new Thickness(350, 450, 0, 0);
r2.VerticalAlignment = System.Windows.VerticalAlignment.Top;
r2.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
l = new Line();
l.X1 = 75;
l.Y1 = 75;
l.X2 = 375;
l.Y2 = 475;
l.Fill = new SolidColorBrush(Colors.Purple);
l.Stroke = new SolidColorBrush(Colors.Purple);
l.StrokeThickness = 2;
l.SetValue(Canvas.ZIndexProperty, -1);
PathGeometry myPathGeometry = new PathGeometry();
// Create a figure.
PathFigure pathFigure1 = new PathFigure();
pathFigure1.StartPoint = new Point(75, 75);
pathFigure1.Segments.Add(
new ArcSegment(
new Point(375, 475),
new Size(50, 50),
45,
true, /* IsLargeArc */
SweepDirection.Clockwise,
true /* IsStroked */ ));
myPathGeometry.Figures.Add(pathFigure1);
// Display the PathGeometry.
Path myPath = new Path();
myPath.Stroke = Brushes.Black;
myPath.StrokeThickness = 1;
myPath.Data = myPathGeometry;
myPath.SetValue(Canvas.ZIndexProperty, -1);
LayoutRoot.Children.Add(r1);
LayoutRoot.Children.Add(r2);
LayoutRoot.Children.Add(l);
LayoutRoot.Children.Add(myPath);
