【问题描述】:
我为我奇怪的代码道歉。我是一个完全的新手,只是在学习东西是如何工作的。
我找到了这段代码并对其进行了一些修改。
我的问题是:
我以某种方式管理所有列的对齐方式正确,但我的第一个列“Data1”需要左对齐。我可以在设置中或单击一个按钮来更改它,但是在打印时它与其他的正好对齐。我已经尝试了所有方法,但我的知识可能只有 2%,所以我非常感谢您的帮助。
我有一个 Button1、DataGridView1、PrintPreviewDialog1、PrintDocument1、PrintDialog1
这是表单的图片和打印预览的示例: 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")

有人可以解释一下需要更改的内容,以便在打印时第一列左对齐,其余列在右侧..
提前致谢!!
