如果时普通列：
gridview.rows[i].cells[j].text
如果时模板列，譬如模板列包含TextBoxName,则
TextBox tb = (TextBox)[Convert.ToInt32(e.CommandArgument)].FindControl("TextBoxName")
然后
tb.text 就ok了
[/Quote]gridview.rows[i].cells[j].text 这里的循环还是看不懂，呵呵。是新手，还望大家多多包含~~

[guoziwumingzi]

我用二楼的可以获取，但是在第二行的时候就不知道怎么办了，要循环~~~

你能做什麼的時候，可能我已經死了

这里没有用参数做，抱歉下

gridview.rows[0].cells[0].text 這就是值了。有特別的（如模板列 就用FINDCONTROL（‘NAME’））

支持

[cntenger]

((TextBox)GridView1.Rows[e.RowIndex].FindControl("tbClassId")).Text

這個已經說得很全面了。還不給它的30分

[guoziwumingzi]

我用gridview.rows[0].cells[0].text已经 写好了，给Rows循环了一下，可是没有那么多分送人啊！

[SK_Aqi]

楼主不用愁了,送给我了
看吧我关注你的帖子了啊

[emoheshang]

gridview1.Rows[i].Cells[j].Text.Trim();
