GridView中如何通过Checkbox(模板列)取值?

Answer 1

for (int i = 0; i < GridView1.Rows.Count; i++) 
        { 
            CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1"); 
            if (cbox.Checked == true) 
            { 
                string sqlstr = "delete from " + table_name + " where study_=" + "'" + GridView1.Rows[i].Cells[2].Text.ToString() + "'";//删除选定的信息第三列 
                //OleDbDataAdapter da = new OleDbDataAdapter(sqlstr, conn);//这些作参考 
                //OleDbCommandBuilder cmd = new OleDbCommandBuilder(da); 
                //DataSet ds = new DataSet(); 
                //da.Fill(ds, table_name); 
            } 
        }

gridview中的 Checkbox 让其绑定值。然后可以通过 request.form[""]来获得，需要的是checkbox的value值，，这样可以获得。如果需要具体的值可以用string 的spilt来进行分离逗号,这样感觉挺简单的。

Answer 3

                    string IDS = "";
                    foreach (GridViewRow gv in GridView1.Rows)
                    {
                        CheckBox cb = (CheckBox)gv.FindControl("CheckBox1");
                        if (cb.Checked)
                        {
                            int index = gv.RowIndex;
                            DataKey key = this.GridView1.DataKeys[index];//获取主键
                                Int ID = Convert.ToInt32(key.Values["ID"]);
                            IDS += ID.ToString() + ",";
                        }
                    }

Answer 4

在GridView的摸版列中用HTML控件  CheckBoxLIST  属性 NAME=“CheckBox1” VALUE=“绑定ID”
   然后在后台获取  
    CheckBoxLIST CK；
   string aa="";
   foreach (GridViewRow gv in GridView1.Rows)
      {
        CK=gv.gv.FindControl("CheckBox1")asCheckBoxLIST ;
           if（ck.Rows[0].selected==true）
              {
               string asd=ck.datavalueFiled;
                aa+=asd+",";
             }
        }
 获取到你所有选中的ID
