vb.net - 在输入键事件的变量中获取 vb.net 中 datagridview 的所有列值

Question

Private Sub dgcustomerlist_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles dgcustomerlist.KeyPress
    Dim custcode As String
    Dim custname As String
    Dim custmobile As String
    'Dim rows As DataGridViewRow = dgcustomerlist.SelectedRows(0)


    If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Enter) Then
        custcode = dgcustomerlist.SelectedCells(0).Value
        custname = dgcustomerlist.SelectedCells(1).Value
        custmobile = dgcustomerlist.SelectedCells(2).Value
        MsgBox("the selected value is", custcode)
    End If

继承人上面的代码，情况是我想要特定变量中gridview中所选行的列值。但是我在custname中遇到错误，因为它抛出了超出范围的索引。请告诉我我做错了什么。

出现此错误是因为代码运行时未选择 CustName 单元格（可能是因为按 ENTER 取消选择它）。

您可以设置DataGridView.SelectionMode = DataGridViewSelectionMode.FullColumnSelect，也可以使用.CurrentRow.Cells代替.SelectedCells; 例如：

custcode = dgcustomerlist.CurrentRow.Cells(0).Value
custname = dgcustomerlist.CurrentRow.Cells(1).Value
custmobile = dgcustomerlist.CurrentRow.Cells(2).Value
