Creating a Predefined Shape

This topic demonstrates how to create a predefined shape through the Infragistics Excel Engine.

The topic is organized as follows:

Requirements

  • Infragistics4.Documents.Excel.v24.1 assembly added to your Visual Studio Windows Forms project

  • A button with a Click event

Code Example: Creating a Predefined Shape

Introduction

The code snippet below creates a predefinedshape with the following parameters:

  • Shape: Diamond

  • Flipped Horizontally: True

  • Flipped Vertically: True

  • Fill: DeepSkyBlue

  • Outline: Black

You need to paste the code into the Click event of the button.

Explanatory comments for each manipulation of the shape are being provided in the code.

Preview

Following is a preview of the final result.

Code Snippet

In C#:

// Use a workbook and worksheet to hold the predefined shape
Infragistics.Documents.Excel.Workbook workbook = new Infragistics.Documents.Excel.Workbook();
Infragistics.Documents.Excel.Worksheet worksheet = workbook.Worksheets.Add("Shapes");
// Creating a predefined shape
WorksheetShape shape = WorksheetShape.CreatePredefinedShape(PredefinedShapeType.Diamond);
// How to set a shape's text value
WorksheetShapeWithText shapeWithText = shape as WorksheetShapeWithText;
if (shapeWithText != null)
{
    shapeWithText.Text = new FormattedText("Your Text");
}
// How to flip a shape horizonatally
shape.FlippedHorizontally = true;
// How to flip a shape vertically
shape.FlippedVertically = true;
// How to fill a shape with color
shape.Fill = ShapeFill.FromColor(Color.DeepSkyBlue);
// How to create an outline around a shape with color
shape.Outline = ShapeOutline.FromColor(Color.Black);
// How to set the position of the shape
//  - Set the top left corner of the shape to cell A0
shape.TopLeftCornerCell = worksheet.Rows[0].Cells[0];
//  - Set the bottom right corner of the shape to cell D12
shape.BottomRightCornerCell = worksheet.Rows[11].Cells[4];
// Add the shape to the worksheet
worksheet.Shapes.Add(shape);
// Save the workbook
workbook.Save("your_workbook.xls");

In Visual Basic:

' Use a workbook and worksheet to hold the predefined shape
Dim workbook As New Infragistics.Documents.Excel.Workbook()
Dim worksheet As Infragistics.Documents.Excel.Worksheet = workbook.Worksheets.Add("Shapes")
' Creating a predefined shape
Dim shape As WorksheetShape = WorksheetShape.CreatePredefinedShape(PredefinedShapeType.Diamond)
' How to set a shape's text value
Dim shapeWithText As WorksheetShapeWithText = TryCast(shape, WorksheetShapeWithText)
If shapeWithText IsNot Nothing Then
    shapeWithText.Text = New FormattedText("Your Text")
End If
' How to flip a shape horizonatally
shape.FlippedHorizontally = True ' How to flip a shape vertically
shape.FlippedVertically = True ' How to fill a shape with color
shape.Fill = ShapeFill.FromColor(Color.DeepSkyBlue)
' How to create an outline around a shape with color
shape.Outline = ShapeOutline.FromColor(Color.Black)
' How to set the position of the shape'  - Set the top left corner of the shape to cell A0
shape.TopLeftCornerCell = worksheet.Rows(0).Cells(0)
' Set the bottom right corner of the shape to cell D12
shape.BottomRightCornerCell = worksheet.Rows(11).Cells(4)
' Add the shape to the worksheet
worksheet.Shapes.Add(shape)
' Save the workbook
workbook.Save("your_workbook.xls")
