Then the method suggested by Apex will work for you. Create the method in a class file and call it where ever it is required.

As I understand need to populate two dropdownlists use the same datasource and bind both ddl. private void CategoryListBind() { ItemCategoryBE objCat = new ItemCategoryBE(); objCat.ID = 0; DataSet ds = new DataSet(); ds = ItemCategoryBL.SelectCategoryBL(objCat); ddlCate .DataSource = ds; ddlCate .DataTextField = "CName"; ddlCate .DataValueField = "ID"; ddlCate .DataBind(); ddlsecond .DataSource = ds; ddlsecond .DataTextField = "CName"; ddlsecond .DataValueField = "ID"; ddlsecond .DataBind(); }

Pretty easy i think: since it's an object you want to address, just hand down the name of your ddl to the function. I'm not 100% sure, you might need to put it in by reference instead of by value. But try! private void CategoryListBind( DropDownList ddl ) { ItemCategoryBE objCat = new ItemCategoryBE(); objCat.ID = 0; DataSet ds = new DataSet(); ds = ItemCategoryBL.SelectCategoryBL(objCat); ddl .DataSource = ds; ddl .DataTextField = "CName"; ddl .DataValueField = "ID"; ddl .DataBind(); }

Thanks for your reply Apex/Madhu. but this is not the way to create a factory class. i want to use this function in whole project. where i have 9 dropdownlist on different pages. if i go with madhu ur option i have to set 9 ddl name thts a bad idea. i have to create a public function(FACTORY CLASS) which can be accessible on any ddl tht code is just an idea only Amit waiting for ur reply Thanks
