#region 维护视图状态
protected override void LoadViewState(object savedState)
{
Triplet tp = savedState as Triplet;
this.TotalRecord = Convert.ToInt32(tp.Third);
this.Info = tp.Second as PageInfo;
base.LoadViewState(tp.First);
}
protected override object SaveViewState()
{
Triplet tp = new Triplet();
tp.First = base.SaveViewState();
tp.Second = Info;
tp.Third = this.TotalRecord;
return tp;
}
#endregion
这里也不必说，只是PageInfo一定要能Serializable。
重写方法
复制代码 代码如下:
#region 重写方法
protected override void RenderContents(HtmlTextWriter writer)
{
writer.Write(GetContents());
base.RenderContents(writer);
}
protected override void AddAttributesToRender(HtmlTextWriter writer)
{
writer.AddStyleAttribute("White-space", "nowrap");
writer.AddStyleAttribute("padding-top", "2px");
writer.AddStyleAttribute("padding-bottom", "2px");
writer.AddStyleAttribute("color", "#949494");
writer.AddStyleAttribute("font-weight", "bold");
writer.AddStyleAttribute("background-color", this.BarBackGroundColor);
base.AddAttributesToRender(writer);
}
#endregion
也不用说，大家一看都明白。
实现ICallbackEventHandler
复制代码 代码如下:
#region ICallbackEventHandler 成员
public string GetCallbackResult()
{
StringBuilder sb=new StringBuilder ();
StringWriter sw=new StringWriter (sb);
getRpt().RenderControl(new HtmlTextWriter(sw));
return this.GetContents() + "[_]" + sb.ToString();
}
public void RaiseCallbackEvent(string eventArgument)
{
int pageindex = int.Parse(eventArgument);
this._CurrentIndex = pageindex;
BindData();
}
#endregion
回调时先执行RaiseCallbackEvent，所以CurrentIndex改变了， BindData()执行了！！！！
返回时时执行GetCallbackResult，string用"[_]"分开，对应上面注册的AjaxPagerCallBack js方法中的var parts =returnData.split('[_]');
OK！简单的Ajax分页就这样简单的完成了！！！
Northwind Orders表调用如下：
页面中Repeater包含在<div></div>中
代码
复制代码 代码如下:
private void BindPage(string content)
{
SinoHelper.PageInfo info = new SinoHelper.PageInfo();
info.PageSize = 5;
info.RepeaterUniqueID = rpt.UniqueID;
info.TableName = "Orders";
info.Fields = "OrderID,CustomerID,ShipCity";
info.IdentityField = "OrderID";
info.Content = content;
AjaxPager1.Info = info;
AjaxPager1.BindData();
}
