如何改变在Datagridview对特定列打印?

Question

我为我奇怪的代码道歉。我是一个完全的新手，只是在学习如何工作。

我找到了这段代码，并对其进行了一些修改。

我的问题是:

我设法为所有列对齐是正确的，但我需要我的第一列&;data1 &;左对齐。我可以通过设置或点击按钮来改变它，但打印时它正好与其他对齐。我什么都试过了，但我的知识可能只有2%，所以我真的很感激你的帮助。

我有一个Button1, DataGridView1, PrintPreviewDialog1, PrintDocument1, PrintDialog1

这是一个表单的图片和打印预览的例子:https://drive.google.com/file/d/1VnUzrM9fgiEcJExrXalo7Uo6XKQwT3Sd/view?usp=sharing

这是我的代码

Private mRow As Integer = 0
Private newpage As Boolean = True
Private m_PagesPrinted As Integer = 1
Private Sub Form2_Load(sender As Object, e As EventArgs) Handles MyBase.Load
With DataGridView1
.Rows.Add("Plan 1", "50", "2,99", "28,40", "170,90")
.Rows.Add("Plan 27 a", "80", "14,99", "227,85", "1427,05")
.Rows.Add("Plan 27 b", "808", "47,45", "84,85", "14,05")
.Rows.Add("Plan 27 c", "80", "12,21", "77,10", "27,05")
.Rows.Add("Plan 27 d", "470", "14,50", "15,40", "227,99")
.Rows.Add("Plan 27 e", "2", "99,00", "2,84", "4427,67")
.Rows.Add("Plan 27 f", "4", "10,00", "9,48", "7,74")
.Rows.Add("Plan 27 g", "54", "150,50", "46,64", "127,50")
End With

x2 += rc.Width
h = Math.Max(h, rc.Height)
End If
Next
y2 += h
' next row to print
mRow = thisNDX + 1
If y2 + h > 500 Then
e.HasMorePages = True
mRow -= 1   'causes last row To rePrint On Next page
m_PagesPrinted += 1
newpage = True
Return
End If
Next

End Sub
Private Sub Button1_Click_1(sender As Object, e As EventArgs) Handles Button1.Click
PrintDialog1.Document = PrintDocument1
PrintDialog1.PrinterSettings = PrintDocument1.PrinterSettings
PrintDialog1.AllowSomePages = True
If PrintDialog1.ShowDialog = DialogResult.OK Then
PrintDocument1.PrinterSettings = PrintDialog1.PrinterSettings
PrintDocument1.Print()
End If
End Sub
End Class

谁能告诉我需要改变什么，以便在打印时，第一列左对齐，其余的在右边…

提前感谢!!

你的Select Case没有意义。您的第一个Case匹配DataGridViewContentAlignment.BottomRight两次，然后您的第二个case匹配相同的值两次以上。在所有情况下，都将StringFormat的Alignment设置为StringAlignment.Far。我认为它应该更像这样:

Select Case DataGridView1.Columns(cell.ColumnIndex).DefaultCellStyle.Alignment
Case DataGridViewContentAlignment.TopLeft,
DataGridViewContentAlignment.MiddleLeft,
DataGridViewContentAlignment.BottomLeft
fmt.Alignment = StringAlignment.Near
Case DataGridViewContentAlignment.TopCenter,
DataGridViewContentAlignment.MiddleCenter,
DataGridViewContentAlignment.BottomCenter
fmt.Alignment = StringAlignment.Center
Case DataGridViewContentAlignment.TopRight,
DataGridViewContentAlignment.MiddleRight,
DataGridViewContentAlignment.BottomRight
fmt.Alignment = StringAlignment.Far
