Hi i am very new to iphone programming..i have used DialogViewController in my application. In the following code , addButton.Clicked event will generate an new root element with sections(Table cell) and we can navigating to another page using these sections.
i need NavigationItem(RightBarButtonItem) and its event in every navigating pages to save the datas in current page
its very urgent! Thanks.
Part of My Code:
public partial class AppDelegate : UIApplicationDelegate
{
UIWindow _window;
UINavigationController _nav;
DialogViewController _RootVC;
RootElement _rootElement;
UIBarButtonItem _addButton;
UIBarButtonItem _EditButton;
DataBaseAccess da =new DataBaseAccess();
public string _name;
EntryElement StrainName;
//Load all the datas
private bool LoadMain()
{
_window = new UIWindow (UIScreen.MainScreen.Bounds);
_rootElement = new RootElement("Strain")
{
new Section()
{
(StrainName = new EntryElement ("Strain Name","Enter Name",""))
},
new Section()
{
}
};
List ();
_RootVC = new DialogViewController (UITableViewStyle.Grouped,_rootElement,true);
_nav = new UINavigationController(_RootVC);
//_EditButton= new UIBarButtonItem(UIBarButtonSystemItem.Edit);
_EditButton = new UIBarButtonItem("Delete", UIBarButtonItemStyle.Plain,null);
_addButton = new UIBarButtonItem(UIBarButtonSystemItem.Add);
_RootVC.NavigationItem.LeftBarButtonItem = _EditButton;
_RootVC.NavigationItem.RightBarButtonItem = _addButton;
_addButton.Clicked += (sender, e) =>
{
if (StrainName.Value=="")
{
return ;
}
da.Addnew (StrainName.Value);
var strain = new Strains{Name = StrainName.Value};
var strainElement = new RootElement(StrainName.Value)
{
new Section()
{
new StringElement("Name",strain.Name)
},
new Section()
{
new EntryElement("Strain Type"," Enter Type","")
},
new Section()
{
