那是网格，这是函数......

Sub resetSelect(ByVal s As Object, ByVal e As DataGridCommandEventArgs)
    lblResponse.Text = [want to access text of username here]
    lblResponse.Visible = True
    lblID.Text = dgResetPassword.DataKeys.Item(e.Item.ItemIndex)
End Sub

如何为用户名引用所选项目DataField文本？

Answer 1

用户名在第3列。所以你可以这样做（C＃）：

lblResponse.Text = e.Item.Cells[3].Text;

Answer 2

这将是VB.net的做法。

lblResponse.Text = e.Item.Cells(3).Text

设置表示列及其索引的枚举可能对您有益。因此，您的代码将成为

lblResponse.Text = e.Item.Cells(DataColumns.Username).Text
