为AspxGridView绑定数据

我们可以通过给AspxGridView的DataSource属性或DataSourceID赋值来实现数据绑定。

所支持的数据源类型包括：SqlDataSource、ObjectDataSource、XmlDataSource、AccessDataSource、SiteMapDatasource、LinqDataSource。下面我们为每一种类型举一个示例：

1.使用DataSource属性绑定DataTable

staticstring_connectionstring="数据库连接字符"
DataSetcurrentDs=newDataSet();
using(SqlConnectioncurrentConn=newSqlConnection(_connectionstring))
{
//获取数据
currentConn.Open();
SqlDataAdaptercurrentSda=newSqlDataAdapter("selectrow_number()over(orderbyLogID)asRowNumber,*fromSys_Log",currentConn);
currentSda.Fill(currentDs,"Sys_Log");

this.ASPxGridView1.DataSource=currentDs.Tables["Sys_Log"];
this.ASPxGridView1.DataBind();

currentConn.Close();
}

2.使用DataSourceID属性绑定SqlDataSource

<dxwgv:ASPxGridViewID="ASPxGridView1"runat="server"DataSourceID="SqlDataSource1">
<Columns>
<dxwgv:GridViewDataColumnCaption="LogID"FieldName="LogID"/>
<dxwgv:GridViewDataColumnCaption="发生时间"FieldName="OCCDatetime"/>
<dxwgv:GridViewDataColumnCaption="事件"FieldName="Event"/>
<dxwgv:GridViewDataColumnCaption="类型"FieldName="Type"/>
<dxwgv:GridViewDataColumnCaption="创建人"FieldName="Creator"/>
<dxwgv:GridViewDataColumnCaption="创建日期"FieldName="CreateDate"/>
<dxwgv:GridViewDataColumnCaption="备注"FieldName="Remark"/>
</Columns>
</dxwgv:ASPxGridView>
<asp:SqlDataSource
id="SqlDataSource1"
runat="server"
DataSourceMode="DataReader"
ConnectionString="数据库连接字符"
SelectCommand="selectrow_number()over(orderbyLogID)asRowNumber,*fromSys_Log">
</asp:SqlDataSource>

3.使用DataSourceID属性绑定ObjectDataSource

<dxwgv:ASPxGridViewID="ASPxGridView1"runat="server"DataSourceID="ObjectDataSource1">
<Columns>
<dxwgv:GridViewDataColumnCaption="LogID"FieldName="LogID"/>
<dxwgv:GridViewDataColumnCaption="发生时间"FieldName="OCCDatetime"/>
<dxwgv:GridViewDataColumnCaption="事件"FieldName="Event"/>
<dxwgv:GridViewDataColumnCaption="类型"FieldName="Type"/>
<dxwgv:GridViewDataColumnCaption="创建人"FieldName="Creator"/>
<dxwgv:GridViewDataColumnCaption="创建日期"FieldName="CreateDate"/>
<dxwgv:GridViewDataColumnCaption="备注"FieldName="Remark"/>
</Columns>
</dxwgv:ASPxGridView>
<asp:objectdatasource
id="ObjectDataSource1"
runat="server"
selectmethod="GetAllLog"
typename="AspxGridView.SysLogDAL"/>

其中SysLogDAL.cs代码如下：

usingSystem;
usingSystem.Collections.Generic;
usingSystem.Linq;
usingSystem.Web;
usingSystem.Data;
usingSystem.Data.SqlClient;
usingSystem.Collections;

namespaceAspxGridView
{
publicclassSysLogDAL
{
staticstring_connectionstring="数据库连接字符";
publicstaticICollectionGetAllLog()
{
ArrayListal=newArrayList();
DataSetcurrentDs=newDataSet();
using(SqlConnectioncurrentConn=newSqlConnection(_connectionstring))
{
//获取数据
currentConn.Open();
SqlDataAdaptercurrentSda=newSqlDataAdapter("select*fromSys_Log","Sys_Log");

DataTabledt=currentDs.Tables["Sys_Log"];
foreach(DataRowdrindt.Rows)
{
SysLogEntrye=newSysLogEntry();
e.LogID=Int32.Parse(dr["LogID"].ToString());
e.OCCDatetime=DateTime.Parse(dr["OCCDatetime"].ToString());
e.Event=dr["Event"].ToString();
e.Type=dr["Type"].ToString();
e.Creator=dr["Creator"].ToString();
e.CreateDate=DateTime.Parse(dr["CreateDate"].ToString());
e.Remark=dr["Remark"].ToString();
al.Add(e);
}

currentConn.Close();
}
returnal;
}
}
}

其中SysLogEntry.cs代码如下：

usingSystem;
usingSystem.Collections.Generic;
usingSystem.Linq;
usingSystem.Web;

namespaceAspxGridView
{
publicclassSysLogEntry
{
publicintLogID
{
get;
set;
}
publicDateTimeOCCDatetime
{
get;
set;
}
publicstringEvent
{
get;
set;
}
publicstringType
{
get;
set;
}
publicstringCreator
{
get;
set;
}
publicDateTimeCreateDate
{
get;
set;
}
publicstringRemark
{
get;
set;
}
}
}

4.使用DataSourceID属性绑定LinqDataSource

<dxwgv:ASPxGridViewID="ASPxGridView1"runat="server"DataSourceID="LinqDataSource1">
<Columns>
<dxwgv:GridViewDataColumnCaption="LogID"FieldName="LogID"/>
<dxwgv:GridViewDataColumnCaption="发生时间"FieldName="OCCDatetime"/>
<dxwgv:GridViewDataColumnCaption="事件"FieldName="Event"/>
<dxwgv:GridViewDataColumnCaption="类型"FieldName="Type"/>
<dxwgv:GridViewDataColumnCaption="创建人"FieldName="Creator"/>
<dxwgv:GridViewDataColumnCaption="创建日期"FieldName="CreateDate"/>
<dxwgv:GridViewDataColumnCaption="备注"FieldName="Remark"/>
</Columns>
</dxwgv:ASPxGridView>
<asp:LinqDataSourceID="LinqDataSource1"runat="server"
ContextTypeName="AspxGridView.SysLogDAL"TableName="SysLogEntrys">
</asp:LinqDataSource>

其中AspxGridView.SysLogDAL有一个SysLogEntrys的属性，代码如下（其它代码同例3）

publicICollectionSysLogEntrys
{
get
{
returnthis.GetAllLog();;
}
}

5.使用DataSourceID属性绑定XmlDataSource

<dxwgv:ASPxGridViewID="ASPxGridView1"runat="server"DataSourceID="XmlDataSource1">
<Columns>
<dxwgv:GridViewDataColumnCaption="LogID"FieldName="LogID"/>
<dxwgv:GridViewDataColumnCaption="发生时间"FieldName="OCCDatetime"/>
<dxwgv:GridViewDataColumnCaption="事件"FieldName="Event"/>
<dxwgv:GridViewDataColumnCaption="类型"FieldName="Type"/>
<dxwgv:GridViewDataColumnCaption="创建人"FieldName="Creator"/>
<dxwgv:GridViewDataColumnCaption="创建日期"FieldName="CreateDate"/>
<dxwgv:GridViewDataColumnCaption="备注"FieldName="Remark"/>
</Columns>
</dxwgv:ASPxGridView>
<asp:XmlDataSourceID="XmlDataSource1"runat="server"DataFile="~/Sys_Log.xml"></asp:XmlDataSource>

其中Sys_Log.xml文件内容如下

<?xmlversion='1.0'encoding='gb2312'?> <data> <rowLogID="1"OCCDatetime="2010-06-0910:10:11.083"Event="用户【Wyf】登陆系统"Type="登陆信息"Creator="sa"CreateDate="2010-10-2111:23:08.090"Remark=""/> </data>
