Getting started with ajax.net

In. net1.1.
1. add reference to ajaxpro. dll
2. Add the configuration in <system. Web> in Web. config:
<Httphandlers>
<Add verb = "post, get" Path = "ajaxpro/*. ashx" type = "ajaxpro. ajaxhandlerfactory, ajaxpro"/>
</Httphandlers>
2.ProgramMedium:
The following example shows how to retrieve data from the database and display the data of the first cell in the table on the foreground.
Datademo. aspx. CS:

Private   Void Page_load ( Object Sender, system. eventargs E)
{
Ajaxpro. Utility. registertypeforajax (Typeof(Datademo ));
}


[Ajaxpro. ajaxmethod]
Public Dataset getdataset ()
{
String Constr =   " Provider = Microsoft. Jet. oledb.4.0; Data Source = "   +  
System. Web. httpcontext. Current. Request. physicalapplicationpath +   " DB \ ajaxdemo. MDB " ;
Oledbconnection con =   New Oledbconnection (constr );

Dataset DS =   New Dataset ();
Oledbdataadapter da =   New Oledbdataadapter ( " Select * from student " , Constr );
Da. Fill (DS );


Return DS;
}

Datademo. aspx: < Script >
Function Showdata ()
{
VaR Datasrc = Ajaxprodemo. datademo. getdataset ();
VaR Cols = Datasrc. value. Tables [ 0 ]. Columns. length;
VaR Rows = Datasrc. value. Tables [ 0 ]. Rows. length;
Alert (Cols +   " Cols and "   + Rows +   " Rows " );

}
Function Showall ()
{
VaR Datasrc = Ajaxprodemo. datademo. getdataset ();
VaR Cell = Datasrc. value. Tables [ 0 ]. Rows [ 1 ]. Sname;
Alert (cell );
}
</ Script >

//

< Input type = " Button " Value = " Showdata " Onclick = " Showdata () " >
< Input type = " Button " Value = " Showall " Onclick = " Showall () " >

If the data source is an object array, see the followingCode:

VaR Arrstaffssearchresult = Staffselecter. searchstaffs (ssearchkeyword );

Lstunselectedstafflist. Options. Length =   0 ;

If (Arrstaffssearchresult. Value = Null   | Arrstaffssearchresult. value. Length = 0 )
Return ;


For ( VaR I = 0 ; I < Arrstaffssearchresult. value. length; I ++ )
{
VaR Currstaffs = Arrstaffssearchresult. value [I];
VaR Onewitem = Document. createelement ( " Option " );
Onewitem. Value = Currstaffs. ID;
Onewitem. Text =   " [ "   + Currstaffs. staffno +   " ] "   + Currstaffs. Name;
Lstunselectedstafflist. Add (onewitem );
Lstunselectedstafflist. selectedindex =   0 ;

Currconditionallstaffsobj. Add (onewitem. Value, currstaffs );
}
