【问题描述】:
我有两种形式。一个是datagridview所在的Main.vb,另一个是EditPage.vb一组文本框。如果我单击 datagridview 中的一行并单击 datagridview编辑按钮 /em> 在 Main.vb 中,它将进入 EditPage.vb。然后,点击的行的数据会显示在EditPage.vb中的文本框...我会尝试public我的变量 并将其设置在另一个 form(EditPage.vb) 但仍然没有显示所选行的数据。我的代码有什么问题即使没有错误?
这是我在 Main.vb
中的 datagridview 单元格内容点击的代码Private Sub tblAttendance_CellContentClick(sender As Object, e As DataGridViewCellEventArgs) Handles tblAttendance.CellContentClick
Dim row As DataGridViewRow = tblAttendance.CurrentRow
Try
id = row.Cells(0).Value.ToString()
firstname = row.Cells(1).Value.ToString
lastname = row.Cells(2).Value.ToString
birthdate = row.Cells(3).Value.ToString
position = row.Cells(4).Value.ToString
sex = row.Cells(5).Value.ToString
address = row.Cells(6).Value.ToString
contact_num = row.Cells(7).Value.ToString
email = row.Cells(8).Value.ToString
Catch ex As Exception
MessageBox.Show("Input Data Properly!", "Error Message")
End Try
End Sub
这是 Edit Button 在 Main.vb
中的代码Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
Dim result As Integer = MessageBox.Show("Are you sure you want to Edit the Info?", "Validation", MessageBoxButtons.YesNoCancel)
If DialogResult.Yes Then
Edit_Page.Show()
ElseIf DialogResult.No Then
MessageBox.Show("Edit Cancelled", "Message")
End If
End Sub
这是我在 Main.vb
中的公共变量Public id As Integer
Public firstname As String
Public lastname As String
Public birthdate As String
Public position As String
Public sex As String
Public address As String
Public contact_num As String
Public email As String
我的公共变量在EditPage.vb中获取公共变量在 Main.vb
Public id_edit As Integer
Public firstname_edit As String
Public lastname_edit As String
Public birthdate_edit As String
Public position_edit As String
Public sex_edit As String
Public address_edit As String
Public contact_num_edit As String
Public email_edit As String
Edit.Page.vb形式的代码或称为Edit_Page_Load
的代码 id_edit = Main.id
firstname_edit = Main.firstname
lastname_edit = Main.lastname
birthdate_edit = Main.birthdate
position_edit = Main.position
sex_edit = Main.sex
address_edit = Main.address
contact_num_edit = Main.contact_num
email_edit = Main.email
firstname_txtbox.Text = firstname_edit
lastname_txtbox.Text = lastname_edit
DateTimePicker1.Text = birthdate_edit
position_txtbox.Text = position_edit
sex_combo.Text = sex_edit
address_txtbox.Text = address_edit
contact_mask.Text = contact_num_edit
email_txtbox.Text = email_edit
再次,我的问题是我无法在 MAIN.VB 和 中获取我的 DATAGRIDVIEW 的选定行的数据>在 EDITPAGE.VB 的文本框中显示它。
【问题讨论】:
-
不要在你的问题上附加不相关的标签。
-
@TJWolschon 很抱歉,同时编辑。
-
@JacobH 很好,只是希望标签正确。
-
我可能会为此被钉死在十字架上,但如果您打算以这种方式在这些表单之间共享数据,也许在这里为共享变量设置一个单独的模块比较好?
-
对不起,但我想找到我罕见问题的答案,因为我在 vb.net 中从未遇到过此类问题。我找不到确切的答案。
