Clientscriptmanager manages client scripts

ClientscriptmanagerClass is used to manage client scripts and add them to Web ApplicationsProgram. You can obtain a reference to the clientscriptmanager class from the clientscript attribute of the page object.

ProgramSource code: Clientscriptmanager.rar

Add a script to the client:

/**/ ///   <Summary>
/// Add a script to the client
///   </Summary>
///   <Param name = "page"> Page for adding a script </Param>
///   <Param name = "csname"> Script key </Param>
///   <Param name = "cstext"> Script content </Param>
Public   Void Registerclientscriptblock (page, String Csname, String Cstext)
{
Clientscriptmanager CS = Page. clientscript;
Type cstype = Page. GetType ();

If ( ! CS. isclientscriptblockregistered (cstype, csname ))
{
CS. registerclientscriptblock (cstype, csname, cstext,True);
}

}

For example:

Protected   Void Page_load ( Object Sender, eventargs E)
{
Scriptmanager= NewScriptmanager ();
Scriptmanager. registerclientscriptblock (This,"Testalert","Alert ('test alert! ');");
}

Add an array to the client:

/**/ ///   <Summary>
/// Register the Javascript array declaration with the Page Object using the array name and array value.
///   </Summary>
///   <Param name = "page"> Page for adding scripts </Param>
///   <Param name = "arrayname"> Array name </Param>
///   <Param name = "array"> Array value </Param>
Public   Void Registerarraydeclaration (page, String Arrayname, array)
{
Stringbuilder sbarrayvalue = New Stringbuilder ();
For ( Int I =   0 ; I < Array. length; I ++ )
{
If (I ! =   0 )
{
Sbarrayvalue. append (",\""+ Array. getvalue (I). tostring () +"\"");
}
Else
{
Sbarrayvalue. append ("\""+ Array. getvalue (I). tostring () +"\"");
}
}

Clientscriptmanager CS = Page. clientscript;
CS. registerarraydeclaration (arrayname, sbarrayvalue. tostring ());
}

For example:

Protected   Void Page_load ( Object Sender, eventargs E)
{
String Arrayname =   " Testarray " ;
Int [] Array = {1,2,3} ;
Scriptmanager =   New Scriptmanager ();
Scriptmanager. registerarraydeclaration ( This , Arrayname, array );

Stringbuilder cstext =   New Stringbuilder ();
Cstext. append ( " Function dosum (){ " );
Cstext. append ( " VaR arrsum = " );
Cstext. append ( " Parseint ( "   + Arrayname +   " [0]) + " );
Cstext. append ( " Parseint ( "   + Arrayname +   " [1]) + " );
Cstext. append ( " Parseint ( "   + Arrayname +   " [2]); " );
Cstext. append ( " Alert (arrsum ); " );
Cstext. append ( " } " );

Scriptmanager. registerclientscriptblock ( This , " Sum " , Cstext. tostring ());
Btndosum. onclientclick =   " Dosum (); Return false " ;

}

The client script includes:

/**/ ///   <Summary>
/// Use the key and URL to register the client script inclusion with the page object.
///   </Summary>
///   <Param name = "page"> Page for adding scripts </Param>
///   <Param name = "includename"> The key of the client script to be registered. </Param>
///   <Param name = "url"> The URL of the client script to be registered. </Param>
Public   Void Registerclientscriptinclude (page, String Includename, String URL)
{
Clientscriptmanager CS=Page. clientscript;
CS. registerclientscriptinclude (includename, URL );
}

For example:

Protected   Void Page_load ( Object Sender, eventargs E)
{< br> scriptmanager = New scriptmanager ();
scriptmanager. registerclientscriptinclude ( This , " testinclude " , " JScript. JS " );
}
