GridView checkbox 合计?
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4"
  ForeColor="#333333" GridLines="None" DataKeyNames="ljm"
  OnRowDataBound="GridView1_RowDataBound" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" ShowFooter="True">
  <FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
  <Columns>
  <asp:TemplateField>
  <ItemTemplate>
  <asp:CheckBox ID="CheckBox1" runat="server" />
  </ItemTemplate>
  </asp:TemplateField>
  <asp:BoundField DataField="ljm" HeaderText="ljm" ReadOnly="True" Visible=False />
  <asp:BoundField DataField="zz" HeaderText="zz" />
  <asp:BoundField DataField="jkrq" HeaderText="jkrq" />
  <asp:BoundField DataField="ywzy" HeaderText="ywzy" />
  <asp:BoundField DataField="jf" HeaderText="jf" />
  <asp:BoundField DataField="df" HeaderText="df" />
  </Columns>
  <RowStyle BackColor="#FFFBD6" ForeColor="#333333" />
  <SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" ForeColor="Navy" />
  <PagerStyle BackColor="#FFCC66" ForeColor="#333333" HorizontalAlign="Center" />
  <HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="White" Font-Size="10pt" />
  <AlternatingRowStyle BackColor="White" />
  </asp:GridView>  


  protected void CheckBox2_CheckedChanged(object sender, EventArgs e)
  {
  for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
  {
  CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
  if (CheckBox2.Checked == true)
  {
  cbox.Checked = true;
   
  }
  else
  {
  cbox.Checked = false;
   
  }
  }
   
  }

可以实现选择,但是如何能做到在选择行后,在页脚处显示选择行的合计呢?谢谢!

------解决方案--------------------------------------------------------
同样用查找控件的方法,把当前所选择行的数据合计起来放在页脚处
------解决方案--------------------------------------------------------
if (CheckBox2.Checked == true)
{
cbox.Checked = true;
count+=int.Parse(e.Row.Cells[1].Text);
 
}
