datagrid 模版列操作问题

 

Thanks  for  posting  in   this  group.
I think maybe you bind the database data into your datagrid every time  in
WebForm load  event .
Because when you click the button, the page postback to the server,
Page_Load  event  fires, the datagrid will be rebind again. So the
ItemCommand will not fire(the datagrid was reinitialized). (You can
demonstrate  this  through add a breakpoint  in  ItemCommand eventhandler)
So you should bind the datagrid only when the page  is  not postback.
Code snippet like  this :

// I use default sqlserver database to fill the datagrid
private   void  Page_Load( object  sender, System.EventArgs e)
{
    // Put user code to initialize the page here
    //Response.Write(Session[0]);
    Response.Write(this.GetPostBackEventReference(hoho));
    if(!IsPostBack)
    {
        SqlDataAdapter adapter=new SqlDataAdapter("select * from
jobs","server=localhost;database=pubs;uid=sa;pwd=");
        DataSet ds=new DataSet();
        adapter.Fill(ds);
        DataGrid1.DataSource=ds;
        DataGrid1.DataBind();
    }
}

this .DataGrid1.ItemCommand  +=   new
System.Web.UI.WebControls.DataGridCommandEventHandler( this .DataGrid1_ItemCom
mand);

private   void  DataGrid1_ItemCommand( object  source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
    if(e.CommandName=="buttonclick")
    {
        Response.Write(e.Item.Cells[3].Text);
    }
}
