SegmenetedControl Selection Changed fired on app load

Benjamin

Asked On September 19, 2019 06:05 AM UTC

it seems that Segmented Control's SelectionChanged Event is being fired twice when the app load.

when the event was fired first time the selectedIndex is -1, 2nd time it is 0.

how do i stop this such that the event will not fire at all during the first load

i only want the event to fired when user actually go and change the control by clicking on it.

i am currently binding the event like this

<buttons:SfSegmentedControl x:Name="monthDate" DisplayMode="Text" SelectionChanged="MonthDate_SelectionChanged" />

Hi Benjamin,

Greetings from Syncfusion.

We have analyzed your query and we would like to inform you that we have fixed this problem with the feature “SfSegmentedControl without setting the SelectedItem when loading initially”. We have implemented this feature in our Vol 3 2019 release. By using this feature, you can achieve your requirement. This release will be available on Sep 20^th, 2019. We will let you know once it gets rolled out.

Regards,

Hi Benjamin,

We have tried to reproduce the reported issue at our end with latest beta release. But the event not fired multiple times. We have attached the tested sample.

Sample – https://www.syncfusion.com/downloads/support/directtrac/general/ze/SimpleSample2078582983.zip

We suspect that, you may have cache problem. So clear the NuGet cache as mentioned in KB- https://www.syncfusion.com/kb/6987/how-to-clear-nuget-cache

And we also suspect the event fired multiple times is due to your implementation architecture. So, we suggested to use flag field to ignore code execution at event fire by workaround. If the workaround does not suit you please revert us by modifying the above sample, that will help us to validate further.

bool isLoad;

public MainPage()

{

isLoad = true;

InitializeComponent();

}

private void Image_Text_SelectionChanged(object sender, SelectionChangedEventArgs e)

{

if(!isLoad)

{

/// your Configuration.

}

isLoad = false;

}

Regards,

Saravanan.
