Gday, As for your first eror on function init, be sure to type it with a return type of void -- function init():Void --
Regarding the mx:columns error, I'm assuming you are including the mx namespace where you are using your PagedDataGrid as well. For a reference of an extended datagrid, take a look at Jim Liang's WG DataGrid http://www.mail-archive.com/[email protected]/msg06733.html Cheers, Andrew Spaulding www.flexdaddy.info --- In [email protected], "sanjayd" <[EMAIL PROTECTED]> wrote: > Can somebody please post some sample code (or a link to sample code) > that extends DataGrid..or, maybe, somebody can look at this code (see > below), and tell me how to fix these compile errors: > > > ------------------------ the error ------------------------------ > 1 Error, 1 Warning found. > > Warning /PagedDataGrid.as:21 > The function, init, hides a function in ancestor class, > 'mx.controls.DataGrid'.
