个人喜欢用Repeater，因其简洁，此AjaxPager定向为Repeater！
一步一步看来：
代码
复制代码 代码如下:
[DefaultProperty("TotalRecord"),
ToolboxData("<{0}:AjaxPager runat=server></{0}:AjaxPager>")]
public class AjaxPager : WebControl,ICallbackEventHandler
{
public AjaxPager()
: base(HtmlTextWriterTag.Div)
{
this.Load += new EventHandler(AjaxPager_Load);
}
void AjaxPager_Load(object sender, EventArgs e)
{
string script = "function AjaxPagerCallBack(returnData){var parts =returnData.split('[_]'); document.getElementById('" + this.UniqueID.Replace ('$','_') + "').innerHTML = parts[0];document.getElementById('" + Info.ContainID + "').innerHTML=parts[1]}";
this.Page.ClientScript.RegisterClientScriptBlock(this.Page.GetType(), "AjaxPagerCallBack", script, true);
}
}
这里在Load事件里向页面注册了一段JS，AjaxPagerCallBack方法做两个操作，把自己表现的数据放入自己在客户端生成的DIV容器里，即id为this.UniqueID.Replace('$','_')的div,ClientID好像也可以！哈，一时糊涂！第二步就是把分页数据放到id为Info.ContainID的div中，Info对象下面会说到。
变量属性
复制代码 代码如下:
#region 变量
private string _BarBackGroundColor = "#FFFFFF";
private string _BarLinkColor = "Navy";
private string _BarCurrentColor = "#EEEEEE";
private int _TotalRecord = 50;
private int _TotalPage = 0;
private int _CurrentIndex = 1;
private int _ItemSize = 10;
private PageInfo _Info=new PageInfo ();
#endregion
#region 属性
#region 外观
[Description("分页背景色"),
Bindable(true),
Category("外观"),
DefaultValue("#FFFFFF")]
public string BarBackGroundColor
{
get { return _BarBackGroundColor; }
set { _BarBackGroundColor = value; }
}
[Description("分页条链接数字颜色"),
Bindable(true),
Category("外观"),
DefaultValue("Navy")]
public string BarLinkColor
{
get { return _BarLinkColor; }
set { _BarLinkColor = value; }
}
[Description("分页条当前页数字颜色"),
Bindable(true),
Category("外观"),
DefaultValue("#EEEEEE")]
public string BarCurrentColor
{
get { return _BarCurrentColor; }
set { _BarCurrentColor = value; }
}
#endregion
#region 行为
[Description("总记录数"),
Category("行为"),
DefaultValue(50)]
public int TotalRecord
{
get { return _TotalRecord; }
set
{
_TotalRecord = value;
}
}
[Description("总页数"),
Category("行为"),
DefaultValue(0)]
public int TotalPage
{
get { return _TotalPage; }
}
[Description("Bar的大小"),
Category("行为"),
DefaultValue(10)]
public int BarSize
{
get { return _ItemSize; }
set
{
foreach (char c in System.Convert.ToString(value))
{
if (!Char.IsNumber(c))
{
_ItemSize = 10;
break;
}
}
_ItemSize = value;
}
}
[Description("当前页值"),
Category("行为"),
DefaultValue(1)]
public int PageIndex
{
get { return _CurrentIndex; }
set { _CurrentIndex = value; }
}
#endregion
public PageInfo Info
{
get { return _Info; }
set { _Info = value; }
}
#endregion
这里自不必细说。其中的PageInfo如下：
PageInfo
复制代码 代码如下:
[Serializable]
public class PageInfo
{
private string _RepeaterUniqueID;
private string _ContainID="AjaxData";
private string _TableName = string.Empty;
private string _IdentityField = "ID";
private int _PageSize = 10;
private string _Fields = "*";
private bool _IsDesc = true;
private string _Content = string.Empty;
private string _ConnectStringName = string.Empty;
public string RepeaterUniqueID
{
get { return _RepeaterUniqueID; }
set { _RepeaterUniqueID = value; }
}
public string ContainID
{
get { return _ContainID; }
set { _ContainID = value; }
}
public int PageSize
{
get { return _PageSize; }
set
{
_PageSize = int.Parse(value.ToString());
}
}
public string TableName
{
get { return _TableName; }
set { _TableName = value; }
}
public string IdentityField
{
get { return _IdentityField; }
set { _IdentityField = value; }
}
public string Fields
{
get { return _Fields; }
set { _Fields = value; }
}
public bool IsDesc
{
get { return _IsDesc; }
set { _IsDesc = value; }
}
public string Content
{
get { return _Content; }
set { _Content = value; }
}
public string ConnectStringName
{
get { return _ConnectStringName; }
set { _ConnectStringName = value; }
}
}
这是标记为Serializable，是因为下面要保存到ViewState里。
