------解决方案--------------------
错误 1
<asp:ImageField DataField= "Photo " HeaderText= "Photo: " />
＝＝＝＝＝＝＝＝＝＝＝
ImageField 不具有 DataField 属性
》》》
<asp:ImageField DataImageUrlField= "Photo " HeaderText= "Photo: " />
错误 2
FilterExpression= "EmployeeID=@EmployeeID "
＝＝＝＝＝＝＝
FilterExpression 属性中，参数只能使用占位符
》》》
FilterExpression= "EmployeeID={0} "
