Confirmation of gridview Deletion

<Asp: commandfield
Edittext = "modify"
Canceltext = "cancel"
// Key
Deletetext = '<SPAN class = "handle" onclick = "javascript: Return confirm (confirm_this)"> Delete </span>'

Headertext = "operation"
Buttontype = "Link"
Showeditbutton = "true"
Showdeletebutton = "true"/>

 

However, to register a Javascript script with the client in the background, in the page_load event:

 

String sscript = "Var confirm_this = 'Are you sure you want to delete it? ';";
Clientscriptmanager CSM = page. clientscript;
If (! CSM. isstartupscriptregistered ("_ confirm "))
{
CSM. registerstartupscript (this. GetType (), "_ confirm", sscript, true );
}

 

The principle is very simple, and the effect is very practical.
