Asp.net dynamically generates content on the page

1. Add the placeholder in the specified area on the page.

2. Add a control to placeholder.

Note:CodeIt must be placed in page_load and cannot be judged by ispostback. Otherwise, no control is found.

Sample Code:

String Ssql =   "" ;
Ssql =   @" Select sfcid, sfcdeptid, sfctablename, sfctabletitle
From hp_satisfactioncreate SSC " ;
Ssql =   String . Format (ssql, resources. Resource. syssatisfactiondept );
Dataview dvdata = Tdaiclient. businessdb. getdataview (ssql );
If (Dvdata ! =   Null )
{
// Add carriage return
// Literalcontrol lcval = new literalcontrol ("<br/> ");
// Add Space
// Literalcontrol lcspace = new literalcontrol (@ "& nbsp ;");

If (Dvdata. Count >   0 )
{
/*
* A two-column table is generated here.
*/

// Define table
Htmltable httab =   New Htmltable ();
Httab. style. Add (htmltextwriterstyle. Width, " 100% " );
// Define rows in a table
Htmltablerow htrtr =   New Htmltablerow ();

For ( Int Irow =   0 ; Irow < Dvdata. Count; irow ++ )
{
// Define an example in a row
Htmltablecell htctd =   New Htmltablecell ();
Htctd. style. Add (htmltextwriterstyle. textalign, " Center " );
Htctd. style. Add (htmltextwriterstyle. color, " Blue " );

// Define the linkbutton Control
Linkbutton LBN =   New Linkbutton ();
LBN. Text = Dvdata [irow] [ " Sfctabletitle " ]. Tostring ();
LBN. tooltip = Dvdata [irow] [ " Sfcid " ]. Tostring ();
String Surl =   " Syssatisfactiondept. aspx? Strid = {0} " ;
Surl =   String . Format (Surl, dvdata [irow] [ " Sfcid " ]. Tostring ());
LBN. postbackurl = Surl;

//Add controls
Htctd. Controls. Add (LBN );
Htrtr. cells. Add (htctd );
Httab. Rows. Add (htrtr );

If (Irow %   2   =   0 )
{
Htrtr =   New Htmltablerow ();
}

}
Phcontrol. Controls. Add (httab );
}
}
