【问题描述】:
如何在 vb.net 的 datagridview 中打印选定的列? 因为我想在 vb.net 中打印选定的行,这些行具有真正的可见性。 这是我在“PrintDocument1_PrintPage”中的代码,
With DataGridView1
Dim fmt As StringFormat = New StringFormat(StringFormatFlags.LineLimit)
fmt.LineAlignment = StringAlignment.Center
fmt.Trimming = StringTrimming.EllipsisCharacter
Dim y As Single = 190
Do While mRow < .RowCount
Dim row As DataGridViewRow = .Rows(mRow)
Dim x As Single = 50
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)
e.Graphics.DrawString(DataGridView1.Rows(cell.RowIndex).Cells(cell.ColumnIndex).FormattedValue.ToString(), .Font, Brushes.Black, rc, fmt)
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
-我的问题是,即使它具有错误的可见性,它也会打印我的 datagridview 中的所有行。
