1 protected void Button1_Click(object sender, EventArgs e)
2 {
3 string selectedKeys = ""; //保存所有选中的记录的主键
4 for (int i = 0; i < GVDealNow.Rows.Count; i++)
5 {
6 GridViewRow row = GVDealNow.Rows[i];
7 if (row.RowType == DataControlRowType.DataRow)
8 {
9 //检查是否选中,假设CheckBox的ID为Checkbox1,且在GVDealNow的第一列中
10 CheckBox cb = (CheckBox)row.Cells[9].FindControl("CBsig");
11 //如果选中,则记录选中记录的主键
12 if (cb.Checked)
13 {
14 selectedKeys = selectedKeys + GVDealNow.DataKeys[row.RowIndex].Value.ToString() + ",";
15 }
16 }
17 }
18 if (selectedKeys != "")
19 {
20 selectedKeys = selectedKeys.TrimEnd(new char[] { ',' });
21 //生成sql语句,并执行删除
22 string sql = "delete from tb_Card where CardID in (" + selectedKeys + ")";
23 SqlConnection conn = new SqlConnection("连接字符串");

第一列 和第十列 是模板列!2 {
3 string selectedKeys = ""; //保存所有选中的记录的主键
4 for (int i = 0; i < GVDealNow.Rows.Count; i++)
5 {
6 GridViewRow row = GVDealNow.Rows[i];
7 if (row.RowType == DataControlRowType.DataRow)
8 {
9 //检查是否选中,假设CheckBox的ID为Checkbox1,且在GVDealNow的第一列中
10 CheckBox cb = (CheckBox)row.Cells[9].FindControl("CBsig");
11 //如果选中,则记录选中记录的主键
12 if (cb.Checked)
13 {
14 selectedKeys = selectedKeys + GVDealNow.DataKeys[row.RowIndex].Value.ToString() + ",";
15 }
16 }
17 }
18 if (selectedKeys != "")
19 {
20 selectedKeys = selectedKeys.TrimEnd(new char[] { ',' });
21 //生成sql语句,并执行删除
22 string sql = "delete from tb_Card where CardID in (" + selectedKeys + ")";
23 SqlConnection conn = new SqlConnection("连接字符串");
24 SqlCommand cmd = new SqlCommand(sql);
25 cmd.Connection = conn;
26 cmd.CommandType = CommandType.Text;
27 conn.Open();
28 cmd.ExecuteNonQuery();
29 conn.Close();

绑定代码如下
string sqlstr = "select * from tb_Card C where C.CardStatus=0";
this.GVDealNow.DataKeyNames = new string[] { "CardID" };
sqlBind.gvBind(GVDealNow, sqlstr);
现在我要一次选择多尔衮删除多个 可是怎么都删不掉 一直都是未选中要删除的记录!this.GVDealNow.DataKeyNames = new string[] { "CardID" };
sqlBind.gvBind(GVDealNow, sqlstr);
请大家帮忙解决下!!
这是数据库字段!~!
