In C#.Net WPF Durante UserControl.Carico ->
Qual è il modo migliore di mostrare un vorticoso circolo / 'Carico' Indicatore di UserControl fino a quando non ha finito la raccolta di dati e di eseguire il rendering del contenuto?
Soluzione
Di solito io vorrei creare un layout simile a questo:
<Grid>
<Grid x:Name="MainContent" IsEnabled="False">
...
</Grid>
<Grid x:Name="LoadingIndicatorPanel">
...
</Grid>
</Grid>
Poi di caricare i dati su un thread di lavoro, e quando è finito mi aggiorna l'interfaccia utente, sotto la "MainContent" griglia e attivare la griglia, quindi impostare il LoadingIndicatorPanel la Visibilità è Crollato.
Non so se è questo che vi state chiedendo o, se si voleva sapere come visualizzare un'animazione in etichetta di caricamento.Se è l'animazione che si sta dopo, si prega di aggiornare la tua domanda più specifica.
Altri suggerimenti
Questo è qualcosa che ho lavorato solo di recente, al fine di creare un animazione di caricamento.Questo xaml produrrà animato da un anello di cerchi.
La mia idea iniziale era di creare un adorner e utilizzare questa animazione è contenuto, quindi per visualizzare l'animazione di caricamento in adorner strato grigio e il contenuto sottostante.
Non hanno avuto la possibilità di finire di sicurezza, così ho pensato di postare l'animazione per il vostro riferimento.

Se si è in esecuzione su windows Vista, si possono anche utilizzare l'impostazione predefinita cursore di attesa.
questo.Cursor = Cursors.Attendere;
Utilizzare BusyIndicator.Si tratta di un silverlight cosa.
È possibile visualizzare immagini gif come elemento di caricamento
XAML
<WindowsFormsHost>
<winForms:PictureBox x:Name="pictureBoxLoading" />
</WindowsFormsHost>
CODICE DIETRO
pictureBoxLoading.Image = System.Drawing.Image.FromFile("images/ajax-loader.gif");
