TimerControl应用

 

最近看了一些关于Atlas的文件，有些好东东，摘出来供大家分享。

原来的文章网址：http://atlas.asp.net/docs/atlas/doc/controls/default.aspx#aspnet

最后一个例子的源代码。

                </ContentTemplate>

            </atlas:UpdatePanel>

注：Interval为TimerControl的间隔时间属性，通过修改此值可改变刷新时间

            }

            catch

            {

                nameBBB.Text = "";

                valueBBB.Text = "";

            }

            try

            {

                dr = dv[2 + Convert.ToInt32(ViewState["int"])];

                nameCCC.Text = dr["mc"].ToString();

                valueCCC.Text = dr["SQL"].ToString();

            }

            catch

            {

                nameCCC.Text = "";

                valueCCC.Text = "";           

            }

 

            ViewState["int"]= Convert.ToInt32(ViewState["int"])+ 3;

        }

        else

        {

            ViewState["int"] = 0;

        }

    }

}

注：tickerTimer_Tick为TimerControl的一个事件，为每间隔一段时间后向服务端触发的事件。

上面的例子开发人员可根据自己的要求优化，仅作一下参考！
