Badge conditional visibility

[David Brenchley]

How do I make the visibility of the badge itself conditional?  When I bind to the IsVisible property on the badgeview, the whole badge content becomes hidden.  I just want to hide the badge itself, such as for a selected item in a list.

Hi David, 

 

Thanks for contacting Syncfusion support. 

 

You can achieve this requirement in two ways. 

 

To hide the Badge, you can set empty string to BadgeText property as shown in the below code.  

 

        <badge:SfBadgeView BadgeText="" HorizontalOptions="Center" VerticalOptions="Center" Grid.Column="0"> 

            <badge:SfBadgeView.Content> 

                <Button Text="Primary" WidthRequest="120" HeightRequest="60"/> 

            </badge:SfBadgeView.Content> 

        </badge:SfBadgeView> 

 

Another way to hide the Badge, by setting the BadgeIcon property as None without specifying the BadgeText as shown in the below code.  

 

Note: By default, BadgeIcon value is None.  

 

            <badge:SfBadgeView.BadgeSettings> 

                <badge:BadgeSetting BadgeIcon="None"  BadgePosition="TopRight"/> 

            </badge:SfBadgeView.BadgeSettings> 

 

We have created a simple sample to change the visibility of Badge. Please find the sample from below location.

Demo doesn't appear to work correctly on Android Emulator with SfBadgeView v17.4.0.44 as supplied in project, with the Android app re-targeted for Android 10. I find that the badge never shows, even when selection is "Visible".

Upgrading SfBadgeView to latest 18.4.0.49 and Xamarin.Forms to v4.8 had no effect, still doesn't show the badge.

Hi David Brenchley,

We have checked the reported query with the previously shared sample. In that sample, SfBadgeView BadgeText property not set properly, so that text is not displayed.

Now we have set the BadgeText based on index as per the below code snippet.

[C#]: 

            private void Picker_SelectedIndexChanged(object sender, EventArgs e) 

        { 

            var picker = (Picker)sender; 

            int selectedIndex = picker.SelectedIndex; 

            if (selectedIndex == 0) 

            { 

                badgeView.BadgeText = "new"; 

            } 

            else 

            { 

                badgeView.BadgeText = ""; 

            } 

        } 

Please have a sample from below link
