Hi,

On continue to this tread: https://www.telerik.com/forums/telerikmauicontrols-radentry-in-list-view-value-not-seen

when it look for data its right no data , busy indicator working and later comes the data.

No data should not appear.


  <telerikPrimitives:RadBusyIndicator Grid.Row="0" Margin="0,5,0,0"  x:Name="busyIndicator" IsVisible="{Binding IsVisibleBusyIndicator, Mode=TwoWay}"
                                  AnimationContentHeightRequest="100"
                                  AnimationContentWidthRequest="100"
                                  AnimationContentColor="{DynamicResource PrimaryColor}"
                                                    IsBusy="{Binding IsBusyBusyIndicator, Mode=TwoWay}">
                <telerikPrimitives:RadBusyIndicator.Content>
                    <Label Text="Loading..." TextColor="Black" />
                </telerikPrimitives:RadBusyIndicator.Content>
            </telerikPrimitives:RadBusyIndicator>

Hi Daniel,

The Content property of the RadBusyIndicator is visible when the IsBusy=False. So, based on what your code has, the screenshot is correct.

If you want certain content to be seen while IsBusy=True, then you need to set the BusyContent property and follow these instructions .NET MAUI BusyIndicator Documentation | Custom Busy Content.

Side Notes:

Why are you using TwoWay data binding? It doesn't make sense here. Why do you want the BusyIndicator to change the view model's value? It should only be the view model property changing the BusyIndicator.

Finally, you can bind the same bool property to both IsBusy and IsVisible. There's no need for separate properties in this scenario because it can easily get out of sync.

Updated code snippet

Here is the code I expect you are looking for.:

<Grid>
    <ListView Grid.Row="0" ..../>

    <RadBusyIndicator IsVisible="{Binding IsBusyBusyIndicator}"
                                   IsBusy="{Binding IsBusyBusyIndicator}"
                                   AnimationContentHeightRequest="100"
                                   AnimationContentWidthRequest="100"
                                   AnimationContentColor="{DynamicResource PrimaryColor}"
                                   BackgroundColor="#AAFFFFFF"
                                   BusyContent="Loading..."
                                   Grid.Row="0"/>
</Grid>

Yeah, I noticed that yesterday. This problem is due to a bug in MAUI right now (there's an issue with the [Content] property attribute). This means you cannot set the BusyContent property at all until that that is resolved.

For now, just use your own Label with RadBusyIndicator. For example:

<StackLayout IsVisible="{Binding MyAppIsBusy}">
    <RadBusyIndicator IsBusy="{Binding MyAppIsBusy}" .../>
    <Label Text="Loading..." />
</StackLayout>

I have reported this to the admins.

In the meantime, can you check your Yahoo spam/junk folder and let me know if any replies have been caught there?
