通过外部按钮，如何将gridview选中的内容批量插入数据库 ，不含不符合未选择的

正解 CheckBox cb; for (int i = 0; i < GridView1.Rows.Count; i++) { cb = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("CheckBox1"); if (cb.Checked == true) { //FindControl value string pbh = ((Label)GridView1.Rows[i].FindControl("labbm")).Text.ToString(); …… //Exec Sql } else { cb.Checked = false; //Do nothing }

上述这段代码单独对当前行的插入操作没有任何问题，因为linkbutton在模板里面。 现在button1在gridview之外，所以就不好弄。因为这个不好控制所选行的索引了。具体这部分代码如下：

[/quote] cb = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("CheckBox1"); cb.Checked = true; 你这块为什么直接复制为True,这样的话你的条件一直是成立的，把cb.Checked=true取消掉
