方法一，用 js 实现

 

  <script type="text/javascript">

  //<![CDATA[
  function CheckAll(oCheckbox)

  {

   var GridView1 = document.getElementById("<%=GridView1.ClientID %>");

   for(i = 1;i < GridView1.rows.length-1; i++)

   {

    

    GridView1.rows[i].cells[0].getElementsByTagName("INPUT")[0].checked = oCheckbox.checked;

   }

  }

  

  //]]>
  </script>
 <asp:GridView ID="GridView1" runat="server" Font-Size="12px" BackColor="#FFFFFF"

            GridLines="Both" CellPadding="4" DataKeyNames="id" AutoGenerateColumns="false"  OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowDataBound="GridView1_RowDataBound" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging1">

            <HeaderStyle BackColor="#EDEDED" Height="26px" />

            <Columns>

              <asp:TemplateField>

                <HeaderTemplate>

                  <input id="Checkbox2" type="checkbox" onclick="CheckAll(this)" runat="server" /><label>全选</label>

                </HeaderTemplate>

                <ItemTemplate>

                  <asp:CheckBox ID="ItemCheckBox" runat="server" />

                </ItemTemplate>

              </asp:TemplateField>

              <asp:TemplateField HeaderText="序号">

</asp:TemplateField>

                <asp:BoundField DataField="id" HeaderText="编号" ReadOnly="True" />

                <asp:BoundField DataField="name" HeaderText="姓名" ReadOnly="True" />

                <asp:TemplateField HeaderText="身份证号">

                        </ItemTemplate>

                        

                        <EditItemTemplate>

                            <asp:TextBox ID="TBCard" Text='<%#Eval("card") %>' runat="server"></asp:TextBox>

                            <asp:RequiredFieldValidator ID="RequiredFieldValidator1" Display="Dynamic" ControlToValidate="TBCard" runat="server" ErrorMessage="请填写身份证号"></asp:RequiredFieldValidator>

                      

                        </EditItemTemplate>

                        

                    </asp:TemplateField>

                    

                    <asp:TemplateField HeaderText="学历">

         

                        <ItemTemplate>

                            <%#Eval("xueliText")%>

                        </ItemTemplate>

                        

                        <EditItemTemplate>

                        <asp:HiddenField ID="HDFXueli" runat="server" Value='<%#Eval("xueli") %>' />

                            <asp:DropDownList ID="DDLXueli" runat="server">

                            </asp:DropDownList>         

                        </EditItemTemplate>

                        

                    </asp:TemplateField>

                

                    <asp:TemplateField HeaderText="价格">

                    

                        <ItemTemplate>

                            <%#Eval("price")%>

                        </ItemTemplate>

                        

                        <EditItemTemplate>      

                             <asp:TextBox ID="TBPrice" Text='<%#Eval("price") %>' runat="server"></asp:TextBox>     

                        </EditItemTemplate>

                    

                    </asp:TemplateField>

          <asp:BoundField HeaderText="建立时间" DataField="createdate" ReadOnly="True" />

               <asp:CommandField   ShowEditButton="True" HeaderText="修改" />

               <asp:TemplateField HeaderText="删除">

                <ItemTemplate>

                    <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Delete"

                        Text="删除" OnClientClick="return confirm('您确认删除该记录吗?');"></asp:LinkButton>

                </ItemTemplate>

              </asp:TemplateField>

            </Columns>

 </asp:GridView>  

 

 

       

 在 .CS 中取值：

 

 pp

 protected void Button1_Click(object sender, EventArgs e)

 {
        this.Label1.Text = "";
       
        foreach (GridViewRow gvr in GridView1.Rows)
        {
            CheckBox ch = (CheckBox)gvr.FindControl("ItemCheckBox");
            if (ch.Checked)
            {
                this.Label1.Text += "<li>GridView1 您选择的是（键值）：" + GridView1.DataKeys[gvr.RowIndex].Value.ToString();
              
            }
        }
       
    }

 

 方法二：

 

 <asp:GridView ID="GridView1" runat="server" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging" OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowDataBound="GridView1_RowDataBound" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating" AutoGenerateColumns="False" DataKeyNames="id,name" DataMember="card,price">
            <Columns>
            <asp:TemplateField>
                <HeaderTemplate>
                  <asp:CheckBox ID="CheckBox1" runat="server" Text="全选" AutoPostBack="true" OnCheckedChanged="CheckAll" />
                </HeaderTemplate>
                <ItemTemplate>
                  <asp:CheckBox ID="ItemCheckBox" runat="server" />
                </ItemTemplate>
              </asp:TemplateField>
              <asp:TemplateField HeaderText="序号">
