ASPNETPager常用屬性

建議去封裝好，然后調(diào)用這樣比較容易

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

alwaysshow="True"

PageSize="5"

custominfosectionwidth="20%"

custominfotextalign="Right"

firstpagetext="第一頁(yè)"

showcustominfosection="Right"

showpageindexbox="Always"

textafterpageindexbox="頁(yè)"

UrlPaging="true"

textbeforepageindexbox="跳到第"

width="97%"

onpagechanged="AspNetPager1_PageChanged">

</webdiyer:aspnetpager>

alwaysshow：總是顯示分頁(yè)控件；

PageSize：指定每頁(yè)顯示的記錄數(shù)；

custominfosectionwidth：用戶(hù)自定義信息區(qū)的寬度；

custominfotextalign：用戶(hù)自定義信息區(qū)的對(duì)齊方式；

firstpagetext：第一頁(yè)按鈕上顯示的文本；

horizontalalign：內(nèi)容水平對(duì)齊方式；

lastpagetext：最后頁(yè)按鈕上顯示的文本；

navigationbuttontype：第一頁(yè)、下一頁(yè)、最后一頁(yè)按鈕的類(lèi)型；

nextpagetext：下一頁(yè)按鈕上顯示的文本；

pageindexboxtype：指示頁(yè)索引框的顯示類(lèi)型：有TextBOX和dropdownlist兩種；

pagingbuttonspacing：導(dǎo)航頁(yè)按鈕的間距；

prevpagetext：上一頁(yè)按鈕的顯示的文本；

showcustominfosection：顯示當(dāng)前頁(yè)和總頁(yè)信息，默認(rèn)為不顯示，值為L(zhǎng)EFT時(shí)將顯示在頁(yè)索引前，為right時(shí)顯示在頁(yè)索引后；

showpageindexbox：指定頁(yè)索引文本框或下拉框的顯示方式；

textafterpageindexbox：指定頁(yè)索引文本框或下拉框后的文本；

UrlPaging：是夠使用URL傳遞分頁(yè)的方式來(lái)分頁(yè)；

textbeforepageindexbox：指定頁(yè)索引文本框或下拉框前面顯示的文本；

width：該控件的寬度；

CustomInfoHTML:指定要顯示在用戶(hù)自定義信息區(qū)的用戶(hù)自定義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

獲取或設(shè)置一個(gè)值，該值指定是否總是顯示AspNetPager分頁(yè)按件，即使要分頁(yè)的數(shù)據(jù)只有一頁(yè)。

CurrentPageButtonPosition

當(dāng)前頁(yè)數(shù)字按鈕在所有數(shù)字分頁(yè)按鈕中的位置，可選值為：Beginning（最前）、End（最后）、Center（居中）和Fi
