while progress bar is running how to disable other controls of the page in WPF

Question

How can i have a loading/progress bar on the page while it is taking time to call a service,also until the call and response is not complete the controls should not be accessible

Answer 1

Try this way, Create a empty grid behind the Progress Bar that cover the whole screen and set its opacity of say 0.5 so that background is paritially visible.

<Grid Grid.Row="0" x:Name="GrdProgressBar"  Background="Transparent"  >
        <Grid Background="White" Opacity="0.5"></Grid>
        <StackPanel VerticalAlignment="Center">
            <ProgressBar IsIndeterminate="True" Foreground="Green" Margin="0,5,0,0" ></ProgressBar>
            <TextBlock Text="loading.." FontSize="20"  FontStyle="Italic" Foreground="Black"  HorizontalAlignment="Center" ></TextBlock>
        </StackPanel>
 </Grid>

What you have to done set the visibility of `GrdProgressBara as you do with ProgessBar.

Hope it help you :)
