Question

我是vb.net中的新手。我有一个datagridview，显示交货编号，日期和供应商。现在，我希望管理员查看每个交付到另一个表单的详细信息。我只想知道如何获取所选行的id，然后将能够显示所选ID的等效数据。感谢。

这是我的交货表格代码。

Private Sub dgvDeliveryReport_CellContentDoubleClick(sender As Object, e As DataGridViewCellEventArgs) Handles dgvDeliveryReport.CellContentDoubleClick
        If e.RowIndex < 0 Then Exit Sub

        Dim id As Int32 = dgvDeliveryReport.CurrentRow.Cells(0).Value
        Dim viewDelivery As New frmDeliveryFormReport
        frmDeliveryFormReport.Show()
    End Sub

Answer 1

尝试。

Dim newFrmName as new yourForm

For each row as DataGridViewRow in SampleGrid
    if row.selected = true then
        Dim whatValueYouWant as string = row.cells("ID").value.toString()
        if newFrmName.NameOfTextBoxInForm.Text <> vbEmpty Then
            'NameOfTextBoxInForm is textbox that existing in yourform
            newFrmName.NameOfTextBoxInForm.text = ", " & whatValueYouWant
        Else
            newFrmName.NameOfTextBoxInForm.text = whatValueYouWant
        End If
    End IF
Next

newFrmName.Show()

Answer 2

在frmDeliveryFormReport课程中添加新字段以存储当前行：

private _currentDeliveryReportRow as DataGridViewRow
寻找构造函数：
```
Public Sub New frmDeliveryFormReport()
  ...
End Sub
```
（如果你找不到它，只需继续下一步）。

更改/添加构造函数，使其获取DataGridViewRow参数并存储给定的行：

Public Sub New frmDeliveryFormReport(deliveryReportRow as DataGridViewRow)
   _currentDeliveryReportRow = deliveryReportRow 
End Sub

调整现有dgvDeliveryReport_CellContentDoubleClick以调用新构造函数：

Private Sub dgvDeliveryReport_CellContentDoubleClick(sender As Object, e As DataGridViewCellEventArgs) Handles dgvDeliveryReport.CellContentDoubleClick
    If e.RowIndex < 0 Then Exit Sub

    Dim viewDelivery As New frmDeliveryFormReport(dgvDeliveryReport.CurrentRow)
    frmDeliveryFormReport.Show()
End Sub

然后，您可以通过

访问frmDeliveryFormReport中DeliveryReportRow的所有列

_currentDeliveryReportRow.Cells(<CellIndex>)
