上面是前台的aspx的代码!
1.用GridView ButtonField列 
<asp:ButtonField Text="审核"  CommandName="pass"/>
后台处理事件  这个利用 这个自定义 事件的!
 protected void gvCardInfo_RowCommand(object sender, GridViewCommandEventArgs e)
    
{
        
if (e.CommandName == "pass")
        
{
            
int intRow = int.Parse(e.CommandArgument.ToString()); //获取当前所在行
            int ID = Convert.ToInt32(gvCardInfo.DataKeys[intRow].Value.ToString());
            
string sql = "update Reserve set ReserveStatus=1 where ReserverID="+ID;
            
if (sh.execCommand(sql))
            
{
                bing();
            }

        }


    }

2 全选的效果!!
aspx代码中的这个注意下 checkbox给他启用autopostback
  <asp:TemplateField>
                                
<HeaderTemplate>
                                    
&nbsp;<asp:CheckBox ID="Cball" runat="server" OnCheckedChanged="Cball_CheckedChanged"  AutoPostBack="true"/>
                                
</HeaderTemplate>
                                
<ItemTemplate>
                                    
<asp:CheckBox ID="Cbsig" runat="server" />
                                
</ItemTemplate>
                                
<ItemStyle HorizontalAlign="Center" />
                            
</asp:TemplateField>

后台
 foreach (GridViewRow gr in gvCardInfo.Rows)
        
{
            CheckBox cb 
= (CheckBox)gr.Cells[9].FindControl("Cbsig");
            
if (!cb.Checked)
            
{
                  cb.Checked
=true;
            }

            
else 
            
{
                cb.Checked 
= false;
            }

        }

代码全部贴处理吧!!

            if (lbl == "未审核")
