NHibernate's data paging technology (continued)
I have introduced how to implement data add, modify, and delete in NHibernate. If you have interested friends, please refer to http://www.cnblogs.com/surprise/archive/2004/10/13/51701.aspx. It is here to talk about the previous content.
1. Interface Add
Type object name text attribute value Button Button1 Show DataGrid DataGrid1
2. Code implementation
Double-click the "display" button
Private void Button1_Click (Object Sender, System.Eventargs E)
{
NHDATABIND ();
}
Private void nhDatabase () // data binding code
{
McFG = New Configuration ();
McFg.addxmlfile (System.Web.httpContext.current.server.mappath ("UserHbm.xml");
ISESSION vSession = mcfg.buildsessionFactory (). OpenSession ();
ITransaction vTransaction = vsession.begintransaction ();
Try
{
IList Vlist = vsession.find ("from WebnHibernate.EntityClass); // HQL statement implements data query
DataGrid1.datasource = VLIST;
DataGrid1.databind ();
vTransaction.commit ();
LabMessage.Text = "OK";
}
Catch (Exception EX)
{
vTransaction.rollback ();
LabMessage.Text = "Error";
}
Finally
{
vSession.close ();
}
}
Create a DataGIRD event handling
Private void DataGrid1_pageIndexchanged (Object Source, System.Web.ui.WebControls.DataGridPageChangeDeventargs E)
{
DataGrid1.currentPageIndex = E.NewpageIndex;
NHDATABIND ();
} Finally completed the entire small stuff, I would like to share with everyone.
