I have created a print preview for the data grid view that I want to print. The code works fine but there is slight problem
In the data grid view row, the ID 1 is missing, it always starts from 2. How can I solve this problem? Please help.
My code:
Private Sub PrintDocument1_PrintPage(sender As System.Object, e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
Dim mRow As Integer = 0
Dim newpage As Boolean = True
PrintDocument1.DefaultPageSettings.Landscape = True
With DataGridView1
Dim fmt As StringFormat = New StringFormat(StringFormatFlags.LineLimit)
fmt.LineAlignment = StringAlignment.Center
fmt.Trimming = StringTrimming.EllipsisCharacter
Dim y As Single = e.MarginBounds.Top
Do While mRow < .RowCount
Dim row As DataGridViewRow = .Rows(mRow)
Dim x As Single = e.MarginBounds.Left
Dim h As Single = 0
For Each cell As DataGridViewCell In row.Cells
Dim rc As RectangleF = New RectangleF(x, y, cell.Size.Width, cell.Size.Height)
e.Graphics.DrawRectangle(Pens.Black, rc.Left, rc.Top, rc.Width, rc.Height)
If (newpage) Then
e.Graphics.DrawString(DataGridView1.Columns(cell.ColumnIndex).HeaderText, .Font, Brushes.Black, rc, fmt)
Else
e.Graphics.DrawString(DataGridView1.Rows(cell.RowIndex).Cells(cell.ColumnIndex).FormattedValue.ToString(), .Font, Brushes.Black, rc, fmt)
End If
x += rc.Width
h = Math.Max(h, rc.Height)
Next
newpage = False
y += h
mRow += 1
If y + h > e.MarginBounds.Bottom Then
e.HasMorePages = True
mRow -= 1
newpage = True
Exit Sub
End If
Loop
mRow = 0
End With
End Sub
rows(0) is the first data row, not header row, while cell.RowIndex is 1, so change rows(cell.RowIndex) as rows(cell.RowIndex-1) :
e.Graphics.DrawString(DataGridView1.Rows(cell.RowIndex - 1).Cells(cell.ColumnIndex).FormattedValue.ToString(), .Font, Brushes.Black, rc, fmt)
