Question

The desired scenario:
When I click on the button, I want it to be hidden until async call is completed.

I have a button in xaml like this

    <Button Name="btnLoadNextTransactions" Content="Button" Click="btnLoadNextTransactions_Click"  Visibility="{Binding LoadMore, Converter={StaticResource converter}}" />

and a click event to

 private void btnLoadNextTransactions_Click(object sender, RoutedEventArgs e)
    {
        App.ViewModel.LoadMore = false;
        ApplicationBl<Transaction>.GetDataLoadingCompleted += GetDataLoadingCompleted;
        ApplicationBl<Transaction>.GetData(++offset*10, 10);//works only if I comment out this line
        App.ViewModel.LoadMore = true;
    }

This only works if I comment out async call

//ApplicationBl<Transaction>.GetData(++offset*10, 10);

But that’s not a feature I want to comment out 🙂
I know I’m missing some delagete or dispatcher. I just started coding with SL.

You need to put LoadMore = true in the GetDataLoadingCompleted method.
