Spread Windows Forms and Page Breaks

Some applications allow you to view page breaks for printing. You can use code to add visual indicators for page breaks in Spread for Windows Forms. There are several ways to add visible page breaks in Spread Windows Forms. You can add a border to the row or column, a backcolor to the header, or an image to the header. This example adds visual indicators for the row page breaks. SpreadWinPageBreaks Row Page Breaks Use the following steps to create this example:

  1. Create a form.
  2. Add Spread and three buttons to the form.
  3. Add a list box to the form.
  4. Add the following code.

C#

private void Printing1_Load(object sender, EventArgs e)  
        {  
            fpSpread1.Open("C:\\\Program Files (x86)\\\GrapeCity\\\Spread Studio 9\\\Common\\\CostOfGoodSold.xml");  
        }  

        private void button1_Click(object sender, EventArgs e)  
        {  
            int[] i;  
            i = fpSpread1.GetRowPageBreaks(0);  
            foreach (object o in i)  
            {  
                listBox1.Items.Add(o);  
                // Set a border for the row  
                fpSpread1.Sheets[0].Cells[(int)o, 0, (int)o, fpSpread1.Sheets[0].Columns.Count - 1].Border = new FarPoint.Win.LineBorder(Color.Red, 2, false, true, false, false);  
            }  
        }  

        private void button2_Click(object sender, EventArgs e)  
        {  
            int[] i;  
            i = fpSpread1.GetRowPageBreaks(0);  
            foreach (object o in i)  
            {  
                listBox1.Items.Add(o);  
                // Set the color for a header cell  
                fpSpread1.Sheets[0].RowHeader.Cells[(int)o, 0].BackColor = Color.Red;  
            }  
        }  

        private void button3_Click(object sender, EventArgs e)  
        {  
            FarPoint.Win.Spread.CellType.ImageCellType imagecell = new FarPoint.Win.Spread.CellType.ImageCellType();  
            System.Drawing.Image image = System.Drawing.Image.FromFile("C:\\\Program Files (x86)\\\GrapeCity\\\Spread Studio 9\\\Common\\\SD.ico");  

            int[] i;  
            i = fpSpread1.GetRowPageBreaks(0);  
            foreach (object o in i)  
            {  
                listBox1.Items.Add(o);  
                // Add an image to the header cell  
                fpSpread1.Sheets[0].RowHeader.Cells[(int)o, 0].CellType = imagecell;  
                fpSpread1.Sheets[0].RowHeader.Cells[(int)o, 0].Value = image;  
            }  
        }  

VB

Private Sub Printing1_Load(sender As Object, e As EventArgs) Handles MyBase.Load  
        FpSpread1.Open("C:\\Program Files (x86)\\GrapeCity\\Spread Studio 9\\Common\\CostOfGoodSold.xml")  
    End Sub  

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click  
        Dim i() As Integer          
        Dim o As Object  
        i = FpSpread1.GetRowPageBreaks(0)  
        For Each o In i  
            ListBox1.Items.Add(o)           
            ‘ Set a border for the row     
            FpSpread1.Sheets(0).Cells(CInt(o), 0, CInt(o), FpSpread1.Sheets(0).Columns.Count - 1).Border = New FarPoint.Win.LineBorder(Color.Red, 2, False, True, False, False)  
        Next  
    End Sub  

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click

            ‘ Set a color for the header cell  
            FpSpread1.Sheets(0).RowHeader.Cells(CInt(o), 0).BackColor = Color.Red  
        Next  
    End Sub  

    Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click  
        Dim imagecell As New FarPoint.Win.Spread.CellType.ImageCellType()

            FpSpread1.Sheets(0).RowHeader.Cells(CInt(o), 0).Value = image  
        Next  
    End Sub  

You can use the GetColumnPageBreaks method to get column page breaks. Use the following steps to create an example that gets the column page breaks and sets a border, header color, or adds an image to the header:

  1. Create a form.
  2. Add Spread and three buttons to the form.
  3. Add a list box to the form.
  4. Add the following code.

C#

private void Printing1_Load(object sender, EventArgs e)  
        {  
            fpSpread1.Open("C:\\\Program Files (x86)\\\GrapeCity\\\Spread Studio 9\\\Common\\\CostOfGoodSold.xml");     
        }         

        private void button1_Click(object sender, EventArgs e)

            int[] i;  
            i = fpSpread1.GetColumnPageBreaks(0);  
            foreach (object o in i)  
            {  
                listBox1.Items.Add(o);  
                fpSpread1.Sheets[0].Cells[0, (int)o, fpSpread1.Sheets[0].Rows.Count - 1, (int)o].Border = new FarPoint.Win.LineBorder(Color.Red, 2, true, false, false, false);                 
            }  
        }

            {  
                listBox1.Items.Add(o);  
                fpSpread1.Sheets[0].ColumnHeader.Cells[0, (int)o].BackColor = Color.Red;  
            }  
        }

            {  
                listBox1.Items.Add(o);  
                fpSpread1.Sheets[0].ColumnHeader.Cells[0,(int)o].CellType = imagecell;  
                fpSpread1.Sheets[0].ColumnHeader.Cells[0,(int)o].Value = image;
