[Solved] BeginEdit, AddNew, Mode

[Francois Vanderseypen]

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

PersonForm.Mode=RadDataFormMode.Edit;
PersonForm.AddNewItem();
PersonForm.BeginEdit;

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,

hello.

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.

((DetailDataContext)DataContext).CommentsDataContext(e.Result.Info);
commentsDataForm.ItemsSource = ((DetailDataContext)DataContext).Comments;
commentsDataForm.UpdateLayout();

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
        Dispatcher.BeginInvoke(AddNewItem);
        StartAdding = false;
    };
    bw.RunWorkerAsync();
    #endregion
}

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");

    dataformTime.AddNewItem();
    CurrentItem = timeDomainDataSource.DataView.CurrentAddItem as TimeLog;
    dataformTime.CurrentItem = CurrentItem;
    dataformTime.BeginEdit();
}

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");
    else
    {
        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;
    }

    #endregion
