GridView 中的button LinkButton 事件 CommandName

   一：          <asp:LinkButton ID="LinkButton1" runat="server" CommandName ="updateState"   Text="可用"
                 CommandArgument='<%#Eval("Roleid") %>'/> 

 protected void GVrole_RowCommand(object sender, GridViewCommandEventArgs e)
    {
       if (e.CommandName == "updateState")
       {

           LinkButton Lb = (LinkButton)sender;
           Lb.Text = "禁用"; 
         }     }

LinkButton 可以触发CommandName ，Button ,imgeButon 不能触发

二： <asp:ButtonField CommandName="ShowTeam"  HeaderText="团队信息"
                                Text="团队信息" />
 protected void GVrole_RowCommand(object sender, GridViewCommandEventArgs e)
    {
       if (e.CommandName == "updateState")
       {
           Page.Alert("updateState");
           
        }
       if (e.CommandName == "ShowTeam")
       {
           Page.Alert(e.CommandArgument.ToString());  // e.CommandArgument得到当前行 的索引，可
        int ClientID = Convert.ToInt32(ClientGridview.DataKeys[index].Value.ToString());
得到相应的 数据

 

 ((LinkButton)e.CommandSource).Text = "禁用";     由e.CommandSource得到事件源，也就是LinkButton， 就可以操作这个 linkButton 的属性了    }
       
    }

 

 protected void GVrole_RowCommand(object sender, GridViewCommandEventArgs e)
    {
       if (e.CommandName == "updateState")
       

           if (((LinkButton)e.CommandSource).Text.ToString() == "禁用")
           {
          
           ((LinkButton)e.CommandSource).Text="可用";
           }
           else

 

 三：通过onCommand 命令配置事件

<asp:Button ID="garbage" OnCommand="garbage" OnClientClick="return confirm('确定设为垃圾问题吗？');"  runat="server" Text="垃圾处理"  visible="false " CommandName="garbage"  CommandArgument='<%#Eval("ID") %>'/>

    protected void Refer(object sender, CommandEventArgs e)
    {
        int id = Convert.ToInt32(e.CommandArgument);
       
        using (DataClassesDataContext db = new DataClassesDataContext())
        {
            var QuSupport = db.QuestionSupport.FirstOrDefault(q => q.ID == id);

            if (QuSupport != null)
            {
                content.Text = QuSupport.SupportContent;  //得到Content的内容
                QuSupport.IsRefereed = true; //设置引用为真
                try
                {
                    db.SubmitChanges();
                }
                catch (Exception)
                {

                    throw;
                }
            }
        }
                           

    }
