感谢您帮助我......但我仍然有一个问题，我怎么能得到所选行的数量在gridview .....我tr使用Gridview.editIndex属性，但它给我负面索引..........
实际上我要做的是在gridview中单击编辑按钮后我必须添加下拉列表的记录和我在< asp：template field>中使用的文本框在数据库......单击更新按钮后，两个字段的记录应该根据他们的id添加到数据库中，这已经在gridveiw中.....
To说清楚......我已经填好了。
ID DROPDOWN TEXTBOX编辑
。
，
Id是使用gridview的select comman生成的，但使用templatefield添加了下拉列表.........因此我必须在点击编辑按钮后更新下拉列表和txtbox ..
