UWP: DataGrid + ProgressRing

Question

Error CS0103 The name 'Status' does not exist in the current context

What is the correct syntax in order to make the controller be available in the .cs file?

<controls:DataGridTemplateColumn Header="OrderId">
    <controls:DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <Grid>
                <Grid.ContextFlyout>
                    <MenuFlyout>
                        <MenuFlyoutItem Text="Copy" Icon="Copy" Click="MenuFlyoutItem_Copy" />
                        <MenuFlyoutSeparator />
                        <MenuFlyoutItem Text="Delete" Icon="Delete" Click="MenuFlyoutItem_Delete" />
                    </MenuFlyout>
                </Grid.ContextFlyout>
                <TextBlock Text="{Binding OrderId}" />
                <ProgressRing x:Name="Status" Foreground="Green" IsActive="True" />
            </Grid>
        </DataTemplate>
    </controls:DataGridTemplateColumn.CellTemplate>
</controls:DataGridTemplateColumn>

I suggested that you'd better use Binding to control the IsActive property value of ProgressRing. Then you do not need to get the control instance in code-behind.

<ProgressRing x:Name="Status" Foreground="Green" IsActive="{Binding xxx}" />

https://stackoverflow.com/questions/16375375/how-do-i-access-a-control-inside-a-xaml-datatemplate what's the proper way of getting the parentContainer for the row? var pRing = FindControl(dataGrid, "Status"); pRing.IsActive = false; – James Ellis Feb 21 '19 at 14:26
@JamesEllis Have you checked my reply? I suggested you to use Binding. Why did you still want to get the control in DataTemplate? It's not a best practice. – Xie Steven Feb 25 '19 at 02:25
So if you bind the progress ring what would the best approach be to mimic time delay so that the progress status is shown? – James Ellis Feb 25 '19 at 19:01
@JamesEllis Did you mean that your data is loaded so fast that your progress only shows a short time? The users hardly see ProgressRing, right? – Xie Steven Feb 26 '19 at 02:47
See [Code Sample](https://github.com/Scnck/POC_Basket) trying to determine best appoarch. I want to copy/delete rows within DataGrid while showing a progressRing and mimic time delay. I want the logic to follow best practice. Thank you – James Ellis Feb 26 '19 at 20:15
You used `await Task.Delay(randomNumber);` to mimic time delay to make the ProgressRing show a little time. Then, the user can see it and know someone item has been copied/deleted. Not bad. You could use it. But I don't think you need to deliberately simulate a time-consuming operation to display the ProgressRing control. I think what users want is to save as much time as possible. You don't have to sacrifice the user experience in order to display the ProgressRing control. – Xie Steven Feb 27 '19 at 09:46
If you just want to let the users know someone item has been copied/deleted successfully. You could show a [InAppNotification](https://learn.microsoft.com/en-us/windows/communitytoolkit/controls/inappnotification) when the operation is finished. – Xie Steven Feb 27 '19 at 09:48
This project is just a proof of concept, I'm more looking at the proper way of handling blinding/DataGrid what is the correct way of handling the progressRing start/finish so that I can have multiple copy/deletes running and the progress indicator would be handled correctly? – James Ellis Feb 27 '19 at 13:48
Currently "seleted.isLoading = true;" doesn't automatically refresh the DataGrid. – James Ellis Feb 28 '19 at 01:08
@JamesEllis There's no relationship between 'seleted.isLoading = true' and 'automatically refresh the DataGrid'. If you want to refresh the DataGrid, you need to refresh the ItemsSource. – Xie Steven Feb 28 '19 at 02:16
