主题：[求助]如何设置图片列只能录入一张图片？

这种情况，建议直接改成文件列

如果要用图片列，那就在beforeAddFile事件写代码

If e.DataCol.Name = "产品" Then
    Dim dlg As new OpenFileDialog
    If dlg.ShowDialog = DialogResult.OK Then
        Dim path = e.DataCol.DefaultFolder
        If path = Nothing Then
            path = ProjectPath & "attachments/"
        End If
        If FileSys.FileExists(path & e.DataRow(e.DataCol.Name)) Then
            FileSys.DeleteFile(path & e.DataRow(e.DataCol.Name), 2, 2)
        End If
        e.DataRow(e.DataCol.Name) = FileSys.GetName(dlg.FileName)
    End If
    e.cancel = True
End If
