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)
