晕了,下面是原代码:
<script language="C#" runat="server">
OleDbConnection MyConn;
public void Page_Load(Object src,EventArgs e)
{
//连接词句
string MyConnString = " Provider=Micorsoft.Jet.LOEDB.4.0; Data Source="+Server.MapPath("//")+"DataBase\\db1.mdb";
MyConn=New OleDbConnection(MyConnString);
MyConn.open();
if (!Page.IsPostBack)
{
BingdGrid();
}
}
ICollection CreateTable()
{
string strsel="select * form score";
Dateset ds=new Dateset();
OleDbDataAdapter MyAdapter=new OleDbDataAdapter(strsel,Myconn);
MyAdapter.Fill(ds."score");
return ds.Tables("score").DefaultView;
}
public void BindGrid()
{
score.Datasource=CreateTable();
score.DataBind();
}
//处理EDIT命令
public void DataGrid_EditCommand(Object sender,DataGridCommandEventArgs e)
{
score.EditItemIndex=(int)e.Item.Itemindex;
BindGrid();
}
//处理Cancel命令
public void DataGrid_CancelCommand(Object sender,DataGridCommandEventArgs e)
{
score.EditItemindex=-1;
BindGrid();
}
//处理update命令
public void DataGrid_UpdateCommand(Object sender,DataGridCommandEventArgs e)
{
//更新数据库中的信息
string strname=e.Item.Cells[1].Text;
int intChinese=
Int32.parse(((Textbox)e.Item.Cells[2].Controls[0]).Text);
int intMath=
Int32.Parse(((Textbox)e.Item.Cells[3].Controls[0]).Text);
int intEnglish=
Int32.Parse(((Textbox)e.Item.Cells[4].Controls[0]).Text);
//更新数据库的数据
string strupdate="update score set chinese="+intchinese+",math="+intmath+",endlish="+intenglish+" where name=''"+strname+"";
OleDbCommand mycomm=new OledbCommmand(strupdate,myconn);
mycomm.executenonquery();
