1)创建datagrid数据列/模板列/按钮的操作类:
using system;
using system.collections;
using system.componentmodel;
using system.data;
using system.data.sqlclient;
using system.drawing;
using system.web;
using system.web.sessionstate;
using system.web.ui;
using system.web.ui.webcontrols;
using system.web.ui.htmlcontrols;
namespace webtest
{
/// <summary>
/// datagridcolumn 的摘要说明。
/// </summary>
public class datagridcols
{
public void datagridcolumn()
{
//
// todo: 在此处添加构造函数逻辑
//
}
public static void createcols(system.web.ui.webcontrols.datagrid datagrid1,string datafield,string headertext,int i)
{
boundcolumn cm=new boundcolumn();
cm.datafield=datafield;
cm.headertext=headertext;
cm.headerstyle.width=i;
datagrid1.columns.add(cm);
}
public static void createbutton(system.web.ui.webcontrols.datagrid datagrid1,string commandname,string strtext)
{
buttoncolumn bc=new buttoncolumn();
bc.buttontype=buttoncolumntype.pushbutton;
bc.commandname=commandname;
bc.headertext="操作";
bc.text=strtext;
datagrid1.columns.add(bc);
}
public static void createtemplatecol(system.web.ui.webcontrols.datagrid datagrid1,string id,string headertext)
{
templatecolumn tm=new templatecolumn();
tm.itemtemplate=new ddlistcol(id);
tm.headertext=headertext;
datagrid1.columns.add(tm);
}
}
}
2)简单的数据库操作类
using system;
using system.data;
using system.data.sqlclient;
namespace webtest
{
/// <summary>
/// sqlaccess 的摘要说明。
/// </summary>
public class sqlaccess
{
// string strconn="server=;user id=sa;password=;database=clothing";
// dataset ds;
// sqldataadapter da;
public sqlaccess()
{
//
// todo: 在此处添加构造函数逻辑
//
}
public static void filldataset(string strconnection,string strsql,dataset ds,string tablename)
{
if (strconnection==null || strconnection.length==0)
{
throw new argumentnullexception( "strconnection" );
}
if (strsql==null || strsql.length==0)
{
throw new argumentnullexception( "strsql" );
}
if (ds==null)
{
throw new argumentnullexception( "dataset" );
}
if (tablename==null || tablename.length==0)
{
throw new argumentnullexception( "tablename" );
}
using(sqlconnection conn=new sqlconnection(strconnection))
{
conn.open();
sqldataadapter da =new sqldataadapter(strsql,conn);
da.fill(ds,tablename);
conn.close();
}
}
public static void filldataset(sqlconnection conn,string strsql,dataset ds,string tablename)
{
if (conn==null)
{
throw new argumentnullexception( "sqlconnection" );
}
if (strsql==null || strsql.length==0)
{
throw new argumentnullexception( "strsql" );
}
if (ds==null)
{
throw new argumentnullexception( "dataset" );
}
if (tablename==null || tablename.length==0)
{
throw new argumentnullexception( "tablename" );
}
using(sqldataadapter da =new sqldataadapter(strsql,conn))
{
da.fill(ds,tablename);
conn.close();
}
}
public static dataset getdataset(string strconnection,string strsql)
{
if (strconnection==null || strconnection.length==0)
{
throw new argumentnullexception( "strconnection" );
}
if (strsql==null || strsql.length==0)
{
throw new argumentnullexception( "strsql" );
}
using(sqlconnection conn=new sqlconnection(strconnection))
{
dataset ds=new dataset();
conn.open();
sqldataadapter da =new sqldataadapter(strsql,conn);
da.fill(ds);
conn.close();
return ds;
}
}
public static dataset getdataset(sqlconnection conn,string strsql)
{
if (conn==null)
{
throw new argumentnullexception( "sqlconnection" );
}
if (strsql==null || strsql.length==0)
{
throw new argumentnullexception( "strsql" );
}
using(sqldataadapter da =new sqldataadapter(strsql,conn))
{
dataset ds=new dataset();
da.fill(ds);
conn.close();
return ds;
}
}
public static int executenonquery(string strconnection,string strsql)
{
if (strconnection==null || strconnection.length==0)
{
throw new argumentnullexception( "strconnection" );
}
if (strsql==null || strsql.length==0)
{
throw new argumentnullexception( "strsql" );
}
using(sqlconnection conn=new sqlconnection(strconnection))
{
sqlcommand sqlcmd=new sqlcommand(strsql,conn);
int i= sqlcmd.executenonquery();
conn.close();
return i;
}
}
public static int executenonquery(sqlconnection conn,string strsql)
{
if (conn==null)
{
throw new argumentnullexception( "sqlconnection" );
}
if (strsql==null || strsql.length==0)
{
throw new argumentnullexception( "strsql" );
}
using(sqlcommand sqlcmd=new sqlcommand(strsql,conn))
{
int i=sqlcmd.executenonquery();
conn.close();
return i;
}
}
}
}
3)创建模板列的类(可以创建n种模板列)
using system;
using system.collections;
using system.componentmodel;
using system.data;
using system.data.sqlclient;
using system.drawing;
using system.web;
using system.web.sessionstate;
using system.web.ui;
using system.web.ui.webcontrols;
using system.web.ui.htmlcontrols;
namespace webtest
{
//dropdownlist模板列
public class ddlistcol : itemplate
{
string id;
public ddlistcol(string id)
{
this.id=id;
}
public void instantiatein(control container)
{
dropdownlist dpl = new dropdownlist();
dpl.id=this.id ;
container.controls.add(dpl);
}
}
//checkbox模板列
public class checkboxcol : itemplate
{
string id;
public checkboxcol(string id)
{
this.id=id;
}
public void instantiatein(control container)
{
checkbox checkbox = new checkbox();
checkbox.id=this.id ;
container.controls.add(checkbox);
}
}
}
4)实例:创建数据源和创建datagrid数据列
using system;
using system.collections;
using system.componentmodel;
using system.data;
using system.drawing;
using system.web;
using system.web.sessionstate;
using system.web.ui;
using system.web.ui.webcontrols;
using system.web.ui.htmlcontrols;
using system.data.sqlclient;
namespace webtest
{
/// <summary>
/// webform1 的摘要说明。
/// </summary>
public class webform1 : system.web.ui.page
{
protected system.web.ui.webcontrols.datagrid datagrid1;
protected system.web.ui.webcontrols.button button1;
private void page_load(object sender, system.eventargs e)
{
// 在此处放置用户代码以初始化页面
}
#region web 窗体设计器生成的代码
override protected void oninit(eventargs e)
