.net中实现aspnetpager分页
第一步首先导入aspnetpager控件，然后再把他从工具箱中拖出，代码如下：
<
webdiyer
:
AspNetPager
ID
="aspnetpager1"
runat
="server"
CustomInfoTextAlign
="Left"
FirstPageText
="
首页
"
LastPageText
="
末页
"
NextPageText
="
下一页
"
NumericButtonCount
="5"
PageIndexBoxType
="TextBox"
PrevPageText
="
上一页
"
ShowPageIndexBox
="Never"
PageSize
="20"
AlwaysShow
="True"
CssClass
="paginator"
CurrentPageButtonClass
="cpb"
Wrap
="True"
BorderStyle
="None"
Width
="100%"
UrlPaging
="True"
CustomInfoClass
="info"
CustomInfoHTML
=""
CustomInfoSectionWidth
="0px"
OnPageChanged
="aspnetpager1_PageChanged">
</
webdiyer
:
AspNetPager
>
并且在页面的上部要引用下面代码：
<%
@
Register
Assembly
="AspNetPager"
Namespace
="Wuqi.Webdiyer"
TagPrefix
="webdiyer"
%>
之后要在引用里添加aspnetpager.dll引用
然后在后台page_load里添加以下分页代码：
Page_gkxx
sp =
new
Page_gkxx
();
aspnetpager1.EnableUrlRewriting =
true
;
aspnetpager1.UrlRewritePattern =
"/zuowen/list-"
+ ParentTypeId +
"-"
+ TypeId +
"-"
+ GradeId +
"-{0}.html"
;
sp.InitBindData(Repeater1, aspnetpager1,
"zuowen"
,
"id"
, Sear(), GetFields());
其中InitBindData
方法
代码为：
public
void
InitBindData(
Control
c, Wuqi.Webdiyer.
AspNetPager
aspnet,
string
tbname,
string
tbcolumn,
string
sqlwhere,
string
sfields)
{
aspnet.RecordCount = GetRows(tbname, sqlwhere);
if
(aspnet.RecordCount > 0)
{
string
contype = c.GetType().ToString();
DataSet
ds = GetList(tbname, tbcolumn,sfields,aspnet.PageSize, aspnet.CurrentPageIndex, sqlwhere);
if
(ds.Tables[0].Rows.Count > 0)
{
if
(contype.IndexOf(
"GridView"
) != -1)
{
GridView
gv = (
GridView
)c;
gv.DataSource = ds;
gv.DataBind();
}
else
if
(contype.IndexOf(
"Repeater"
) != -1)
{
Repeater
rep = (
Repeater
)c;
rep.DataSource = ds;
rep.DataBind();
}
else
if
(contype.IndexOf(
"DataList"
) != -1)
{
DataList
dl = (
DataList
)c;
dl.DataSource = ds;
dl.DataBind();
}
c.Visible =
true
;
}
}
else
{
c.Visible =
false
;
}
}
private
int
GetRows(
string
tablename,
string
strwhere)
{
string
strSql =
"select count(1) from "
+ tablename +
" with(nolock) where "
+ strwhere +
""
;
return
int
.Parse(
DbHelperSQL
.GetSingle(strSql).ToString());
}
///

///

///

///

///
<param name="PageIndex"></param>
///

public
DataSet
GetList(
string
tablename,
string
keyname,
string
sfields,
int
PageSize,
int
PageIndex,
string
strWhere)
{
SqlParameter
[] parameters = {
new
SqlParameter
(
"@tblName"
,
SqlDbType
.VarChar, 255),
new
SqlParameter
(
"@fldName"
,
SqlDbType
.VarChar, 255),
new
SqlParameter
(
"@sFields"
,
SqlDbType
.VarChar,1000),
new
SqlParameter
(
"@PageSize"
,
SqlDbType
.Int),
new
SqlParameter
(
"@PageIndex"
,
SqlDbType
.Int),
new
SqlParameter
(
"@IsReCount"
,
SqlDbType
.Bit),
new
SqlParameter
(
"@OrderType"
,
SqlDbType
.Bit),
new
SqlParameter
(
"@strWhere"
,
SqlDbType
.VarChar,1000),
};
parameters[0].Value = tablename;
parameters[1].Value = keyname;
parameters[2].Value = sfields;
parameters[3].Value = PageSize;
parameters[4].Value = PageIndex;
parameters[5].Value = 0;
parameters[6].Value = 1;
parameters[7].Value = strWhere;
return
DbHelperSQL
.RunProcedure(
"Up_GetRecordByPage"
, parameters,
"ds"
);
}
这是在
DbHelperSQL
中的方法：
///
<summary>
///
执行存储过程返回dataset
///
</summary>
///
<param name="storedProcName">
存储过程名
</param>
///
<param name="parameters">
存储过程参数
</param>
///
<param name="tableName">
DataSet结果中的表名
</param>
///
<returns>
DataSet
</returns>
public
static
DataSet
RunProcedure(
string
storedProcName,
IDataParameter
[] parameters,
string
tableName)
{
using
(
SqlConnection
connection =
new
SqlConnection
(connectionString))
{
DataSet
dataSet =
new
DataSet
();
connection.Open();
SqlDataAdapter
sqlDA =
new
SqlDataAdapter
();
sqlDA.SelectCommand = BuildQueryCommand(connection, storedProcName, parameters);
sqlDA.Fill(dataSet, tableName);
connection.Close();
return
dataSet;
}
}
///
<summary>
///
执行一条计算查询结果语句，返回查询结果（object）。
///
</summary>
///
<param name="SQLString">
计算查询结果语句
</param>
///
<returns>
查询结果（object）
</returns>
public
static
object
GetSingle(
string
SQLString)
{
using
(
SqlConnection
connection =
new
SqlConnection
(connectionString))
{
using
(
SqlCommand
cmd =
new
SqlCommand
(SQLString, connection))
{
try
{
connection.Open();
object
obj = cmd.ExecuteScalar();
if
((
Object
.Equals(obj,
null
)) || (
Object
.Equals(obj, System.
DBNull
.Value)))
{
return
null
;
}
else
{
return
obj;
}
}
catch
(System.Data.SqlClient.
SqlException
e)
{
connection.Close();
connection.Dispose();
throw
new
Exception
(e.Message);
}
}
}
}
这是Sear()方法的代码：
///
<summary>
///
根据传值进行搜索分页
///
</summary>
///
<returns></returns>
private
string
Sear()
{
StringBuilder
sb =
new
StringBuilder
();
sb.Append(
"1=1"
);
if
(ParentTypeId != 0)
sb.AppendFormat(
" and ptypeid={0}"
,ParentTypeId);
if
(TypeId != 0)
sb.AppendFormat(
" and typeid={0}"
,TypeId);
if
(GradeId != 0)
sb.AppendFormat(
" and gid={0}"
, GradeId);
return
sb.ToString();
}
这是获取分页中显示的内容代码：
private
string
GetFields()
{
return
"id,title,addtime,Content,typeid,ptypeid,views"
;
}
接着添加分页的事件：
private
void
ZuowenHotBind()
{
DataSet
ds =
ZuowenDal
.GetList(10,
"addtime>'"
+
DateTime
.Now.AddMonths(-3).ToString() +
"'"
,
"views desc"
);
if
(ds.Tables[0].Rows.Count > 0)
{
RepHot.DataSource = ds;
RepHot.DataBind();
}
}
以上操作基本完成了aspnetpager分页是实现，又不懂的问题可以直接评论回复。
(代码用到了封装的
DbHelperSQL
.cs
)
