Creating Borders Around Rows and Columns in Your Table

This topic demonstrates how to create distinct borders around a row and a column by using the LineDef class. This topic assumes you already have a table with three columns and three rows.

1. The following code should already exist in your source file:

• Visual Basic

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

' Make a table.

    Dim table As C1.C1Preview.RenderTable = New C1.C1Preview.RenderTable(Me.C1PrintDocument1)

    table.Style.GridLines.All = New C1.C1Preview.LineDef(Color.DarkGray)

    Dim r As Integer = 3

    Dim c As Integer = 3

Dim row As Integer

Dim col As Integer

    For row = 0 To r - 1 Step +1

For col = 0 To c - 1 Step +1

            Dim celltext As C1.C1Preview.RenderText = New C1.C1Preview.RenderText(Me.C1PrintDocument1)

' Add empty cells.

            celltext.Text = String.Format("", row, col)

            table.Cells(row, col).RenderObject = celltext

' Generate the document.

    Me.C1PrintDocument1.Body.Children.Add(table)

    Me.C1PrintDocument1.Generate()

End Sub

• C#

private void Form1_Load(object sender, System.EventArgs e)

// Make a table.

    C1.C1Preview.RenderTable table = new C1.C1Preview.RenderTable(this.c1PrintDocument1);

    table.Style.GridLines.All = new C1.C1Preview.LineDef(Color.DarkGray);

    const int r = 3;

    const int c = 3;

    for (int row = 0; row < r; ++row)

        for (int col = 0; col < c; ++col)

        C1.C1Preview.RenderText celltext = new C1.C1Preview.RenderText(this.c1PrintDocument1);

            celltext.Text = string.Format("", row, col);

// Add empty cells.

            table.Cells[row, col].RenderObject = celltext;

// Generate the document.

    this.c1PrintDocument1.Body.Children.Add(table);

    this.c1PrintDocument1.Generate();

2. Add the following code to your project to make the table's width and height fifteen centimeters long:

• Visual Basic

table.Height = New C1.C1Preview.Unit(15, C1.C1Preview.UnitTypeEnum.Cm)

table.Width = New C1.C1Preview.Unit(15, C1.C1Preview.UnitTypeEnum.Cm)

• C#

table.Height = new C1.C1Preview.Unit(15, C1.C1Preview.UnitTypeEnum.Cm);

table.Width = new C1.C1Preview.Unit(15, C1.C1Preview.UnitTypeEnum.Cm);

3. Add the following code to your project to assign a new instance of the LineDef class to the borders of the third row as follows (note that the constructor we use specifies that the new border will be red and 2 points wide):

• Visual Basic

table.Rows(2).Style.Borders.All = New C1.C1Preview.LineDef("2pt", Color.Red)

• C#

table.Rows[2].Style.Borders.All = new C1.C1Preview.LineDef("2pt", Color.Red);

4. Assign a new instance of the LineDef class to the borders of the first column as follows (note that the constructor we use specifies that the new border will be blue and 6 points wide):

• Visual Basic

table.Cols(0).Style.Borders.All = New C1.C1Preview.LineDef("6pt", Color.Blue)

• C#

table.Cols[0].Style.Borders.All = new C1.C1Preview.LineDef("6pt", Color.Blue);

Run the program and observe the following:

Your borders will appear similar to the table below at run time:
