how can delete row gridview after clicking button "delete" in form? thank all

here's sample code you'd idea. it's wpf + c#, not web, should drift. idea same.

your main program:

public delegate void deleterow(bool dodelete);  /// <summary> /// interaction logic mainwindow.xaml /// </summary> public partial class mainwindow : window {     int selectedrow = 0;     public deleterow deleterowdelegate;      public void reportdelete(bool delete)     {         // delete row here.     }      public mainwindow()     {         initializecomponent();         deleterowdelegate += new deleterow(reportdelete);     }      private void btnok_click(object sender, routedeventargs e)     {                     // here, row number selectedrow.          secondarywin win = new secondarywin(deleterowdelegate);         win.showdialog();          // @ point, if delete clicked in secondary window, code have executed reportdelete() method.     } } 

and secondary window:

public partial class secondarywin : window {     deleterow callbackdel;      public secondarywin(deleterow callback)     {         initializecomponent();         callbackdel = callback;     }      private void btndel_click(object sender, routedeventargs e)     {         callbackdel.invoke(true);         // close window     } } 

so in main register reportdelete() method deleterow delegate, , pass secondary window. i've passed in constructor, use different method if wishes.

then in secondary window call delegate when click delete button, , exit window.

back in main(), whenever delete clicked in secondary window execute code inside reportdelete() method delete particular row. use selectedrow purpose.
