Hi,

 

I hope anyone can help me on this as my situation is very urgent. If you can see on the attached file, that is the shape that I want to make. So I decided to use the polygon shape which is available in telerik. Below is my sample code :

Telerik.Reporting.Shape polygonShape = new Telerik.Reporting.Shape();

PolygonShape seriesofPolygonShapePoints = new PolygonShape(8,0,0);

PointF[] seriesofPoints = new PointF[8];

seriesofPoints[0] = new PointF(-10,10);

seriesofPoints[1] = new PointF(-10, 4);

seriesofPoints[2] = new PointF(-12, 4);

seriesofPoints[3] = new PointF(-12, 0);

seriesofPoints[4] = new PointF(12, 0);

seriesofPoints[5] = new PointF(12, 4);

seriesofPoints[6] = new PointF(10, 4);

seriesofPoints[7] = new PointF(10, 10);

seriesofPolygonShapePoints.AddLines(points, true);

#region create custom polygon shape
polygonShape = new Telerik.Reporting.Shape
{
ShapeType = seriesofPolygonShapePoints,
Size = new SizeU(
Unit.Inch(.10),
Unit.Inch(.10)),
Stretch = true,
Location = new PointU(
Unit.Inch(coordinateViewModel.LocationOfX),
Unit.Inch(coordinateViewModel.LocationOfY)),
Style = {
BackgroundColor = backgroundColor,
Color = color,
LineWidth = lineWidth
}
};
#endregion
#region add to section
detailSection.Items.AddRange(new Telerik.Reporting.ReportItemBase[] {
polygonShape,
});
#endregion

 

With the above code, the report runs but it doesn't draw properly. It draws the default octagon shape since it has eight side. BUT what I want is the image I attached should display since I provided the points where the line should draw.

I don't know if im missing something in the code or am I missing the points that I need to add to draw the shape properly..

Hope someone can help me immediately..

 

Thanks!!!

Also while im checking in the design view, when added the Shape Control from the telerik object, there is a shapetype property where it only list the available shape that can be used. Since my shape is customized, is it even possible to create a custom shape based on my attached image above?

Need everyone's help especially the experts of telerik devs..

Hi Dondon,

This question has been answered in the support ticket you posted, but I will paste the information here so anyone interested could find it:

When creating a custom shape, the ShapeType property must be set to a new implementation of the ShapeBase class, as shown below:
class MyCustomShape : Drawing.Shapes.ShapeBase
    {
        public override object Clone()
        {
            return new MyCustomShape()
            {
                Bounds = this.Bounds
            };
        }
  
        protected override void CreateShape()
        {          
            PointF[] seriesofPoints = new PointF[8];
            seriesofPoints[0] = new PointF(-10, 10);
            seriesofPoints[1] = new PointF(-10, 4);
            seriesofPoints[2] = new PointF(-12, 4);
            seriesofPoints[3] = new PointF(-12, 0);
            seriesofPoints[4] = new PointF(12, 0);
            seriesofPoints[5] = new PointF(12, 4);
            seriesofPoints[6] = new PointF(10, 4);
            seriesofPoints[7] = new PointF(10, 10);
  
            base.AddLines(seriesofPoints, true);
        }
    }

The shape item can be instantiated and added to the report the following way:
IReportDocument CreateReport()
        {
            var report = new MyReport();
            var detailsSection = report.Items.OfType<DetailSection>().FirstOrDefault();
            detailsSection.Items.Add(this.CreateShape());
  
            return report;
        }
  
        Shape CreateShape()
        {
            var shape = new Shape()
            {
                ShapeType = new MyCustomShape(),
                Size = new Drawing.SizeU(Drawing.Unit.Cm(2), Drawing.Unit.Cm(2)),
                Location = new Drawing.PointU(Drawing.Unit.Cm(1), Drawing.Unit.Cm(1))
            };
            return shape;
        }

The code above will produce a report that has the desired shape in its details section. Currently there is no way to add a design-time support for custom ShapeType implementations, but using code, as demonstrated above, allows to add virtually any kind of shape to a report.
