ASPNETPager常用属性

建议去封装好，然后调用这样比较容易

<webdiyer:aspnetpager id="AspNetPager1" runat="server"

alwaysshow="True"

PageSize="5"

custominfosectionwidth="20%"

custominfotextalign="Right"

firstpagetext="第一页"

horizontalalign="Left"

lastpagetext="末一页"

navigationbuttontype="Image"

nextpagetext="后一页"

pageindexboxtype="TextBox"

pagingbuttonspacing="8px"

PRevpagetext="前一页"

showcustominfosection="Right"

showpageindexbox="Always"

textafterpageindexbox="页"

UrlPaging="true"

textbeforepageindexbox="跳到第"

width="97%"

onpagechanged="AspNetPager1_PageChanged">

</webdiyer:aspnetpager>

alwaysshow：总是显示分页控件；

PageSize：指定每页显示的记录数；

custominfosectionwidth：用户自定义信息区的宽度；

custominfotextalign：用户自定义信息区的对齐方式；

firstpagetext：第一页按钮上显示的文本；

horizontalalign：内容水平对齐方式；

lastpagetext：最后页按钮上显示的文本；

navigationbuttontype：第一页、下一页、最后一页按钮的类型；

nextpagetext：下一页按钮上显示的文本；

pageindexboxtype：指示页索引框的显示类型：有TextBOX和dropdownlist两种；

pagingbuttonspacing：导航页按钮的间距；

prevpagetext：上一页按钮的显示的文本；

showcustominfosection：显示当前页和总页信息，默认为不显示，值为LEFT时将显示在页索引前，为right时显示在页索引后；

showpageindexbox：指定页索引文本框或下拉框的显示方式；

textafterpageindexbox：指定页索引文本框或下拉框后的文本；

UrlPaging：是够使用URL传递分页的方式来分页；

textbeforepageindexbox：指定页索引文本框或下拉框前面显示的文本；

width：该控件的宽度；

CustomInfoHTML:指定要显示在用户自定义信息区的用户自定义HTML信息文本

深入分析CurrentPageIndex、RecordCount、PageCount、PageSize：

pagecount:

public int PageCount

{

get

{

if (this.RecordCount == 0)

{

return 1;

}

return (int) Math.Ceiling((double) (((double) this.RecordCount) / ((double) this.PageSize)));

}

}

recordcount:

public int RecordCount

{

get

{

if (this.cloneFrom != null)

{

return this.cloneFrom.RecordCount;

}

object obj2 = this.ViewState["Recordcount"];

if (obj2 != null)

{

return (int) obj2;

}

return 0;

}

set

{

this.ViewState["Recordcount"] = value;

}

}

CurrentPageIndex:

public int CurrentPageIndex

{

get

{

if (this.cloneFrom != null)

{

return this.cloneFrom.CurrentPageIndex;

}

object obj2 = this.ViewState["CurrentPageIndex"];

int num = (obj2 == null) ? 1 : ((int) obj2);

if ((num > this.PageCount) && (this.PageCount > 0))

{

return this.PageCount;

}

if (num < 1)

{

return 1;

}

return num;

}

set

{

int pageCount = value;

if (pageCount < 1)

{

pageCount = 1;

}

else if (pageCount > this.PageCount)

{

pageCount = this.PageCount;

}

this.ViewState["CurrentPageIndex"] = pageCount;

}

}

PageSize:

public int PageSize

{

get

{

int num;

if ((!string.IsNullOrEmpty(this.UrlPageSizeName) && !base.DesignMode) && (int.TryParse(this.Page.Request.QueryString[this.UrlPageSizeName], out num) && (num > 0)))

{

return num;

}

if (this.cloneFrom != null)

{

return this.cloneFrom.PageSize;

}

object obj2 = this.ViewState["PageSize"];

if (obj2 != null)

{

return (int) obj2;

}

return 10;

}

set

{

this.ViewState["PageSize"] = value;

}

}

AlwaysShow

获取或设置一个值，该值指定是否总是显示AspNetPager分页按件，即使要分页的数据只有一页。

CurrentPageButtonPosition

当前页数字按钮在所有数字分页按钮中的位置，可选值为：Beginning（最前）、End（最后）、Center（居中）和Fi
