那你的图片控件不要绑定列,直接赋值吧。
Dim r As Row = Tables("表A").Current
If r IsNot Nothing
Dim idx As Integer = iif(r.Index>0, r.Index-1, 0)
r = Tables("表A").Rows(idx)
Dim p As String = ProjectPath & "Attachments/" & r("第一列")
If FileSys.FileExists(p)
e.Form.Controls("PictureBox1").Image = getimage(p)
Else
e.Form.Controls("PictureBox1").Image = Nothing
End If
End If
