    The dataform sits in a Page and when OnNavigatedTo is called the following calls do not have any effect:


    I'm probably overlooking the totally obvious.

    Thx, Fr.

    PS: using the RadDomainDataSource to set the CurrentItem on the form.

    Hello Francois Vanderseypen,

    Depending on what is the source object/collection , you may or may not be able to enter edit mode.
    Please give me more details about the data bound to RadDataForm so I can isolate what may be gone wrong.

    All the best,

    I have the same problem, i have a view that i will open on read or new itemmode.

    But in bought cases i will assign the CurrentItem  property to one viewmodel property.

    How can i enter on read or edit mode?

    i also need to have the buttons, Change mode from read to edit,

    begin edit, cancel edit, endedit. 

    I want to wrap a new instance of the object on viewmodel to be able to cancel the edition.

    I don't want to use IEditable object because my Entities simple poco objects... and they need to continue like this.

    Hello Marco Teodoro,

    RadDataForm may work with a single object( given trough the current item property) and with a collection of objects ( given trough  the ItemsSource property) .

    The add functionality will work only when you use the ItemsSource property ( working with  a collection) .
    This is by design and I believe you will observe the same behavior with any DataForm e.g. the one form Microsoft.

    In other works , when using the current item only and not the ItemsSource property , it is not possible to have "Add new " functionality .

    Sincerely ,

    I am having a similar problem.  I am programmatically setting a Collection as the itemsource, but the "add" button is disabled.

    commentsDataForm.ItemsSource = ((DetailDataContext)DataContext).Comments;

    I've been stuck on this for weeks and finally, with the help of this post, got it working.

    I'm using a GridView with a DomainDataSource and DataForm as in the CRM demo.

    OnNavigatedTo I set a "StartAdding" variable to tell the page to try add a new item when it's done.
    Simply hooking on to various Loaded events didn't work.

    What I did was properly wait for everything to be loaded and then began my editing.

    private void DataLoaded(object sender, EventArgs e)
        #region ADD ON DATA LOADED
        // Check for "add mode"
        if (!StartAdding) return;
        // Start background worker
        var bw = new BackgroundWorker();
        bw.DoWork += (o, args) =>
            // Wait for gridview to have items
            while (timeRadGridView.Items.CurrentPosition == -1 || timeRadGridView.Items.ItemCount != timeRadGridView.Items.TotalItemCount)
            { }
            // Dispatch BeginAdd method by AddNewItem
            StartAdding = false;
    private void buttonAdd_Click(object sender, RoutedEventArgs e)
        // Fallback redirect to self
        if(dataformTime.CanAddItems == false && Parent is Grid)
            App.Navigate((Parent as Grid).Parent as Page, "Time/TimeList?mode=add");
        CurrentItem = timeDomainDataSource.DataView.CurrentAddItem as TimeLog;
        dataformTime.CurrentItem = CurrentItem;
    private void BeginAdd()
        #region BEGIN ADD
        // Disable gridview
        timeRadGridView.IsEnabled = false;
        var item = dataformTime.CurrentItem as TimeLog;
        if (item == null)
            App.ShowError("Error adding timelog (BeginAdd)", "Form current item is undefined");
        if (App.CurrentUser.AccountCompany.CompanyId == -1)
            App.ShowError("Error adding timelog (BeginAdd)", "Couldn't find your company");
            item.Created = DateTime.Now;
            item.PersonId = App.CurrentUser.PersonId;
            item.StartDate = DateTime.Now;
            item.TimeLogTypeId = 0;
            item.Disabled = false;
            item.CompanyId = App.CurrentUser.AccountCompany.CompanyId;
            CurrentItem = dataformTime.CurrentItem as TimeLog;
