Codrina Merigo

Asked On July 8, 2019 01:18 PM UTC

Hello,

I have an Xamarin Forms 4 solution and I tried to use the Switchrenderer by following the guide on the website, but I didn't managed to use it, due to a missing reference( I guee code.iOS)

Is there any sample for using the switch?

Thank you, but it's there any way to use the version 17.1.0.53 and have this component?

Hi Codrina,

No. Because we have implemented SfSwitch component in 17.2.0.28 only. So, if you want to use this component, you have to update our version.

Ok, thank you.

One more question, I have created a listview containing a switch with x:Name set to a bindable property of type String "switch" + index(SwitchName).

x:Name="{Binding SwitchName}"

AutomationId="{Binding SwitchName}"

Grid.Row="0"

Grid.Column="1"

AllowIndeterminateState="False"

IsOn="{Binding IsActive}"

StateChanged="SfSwitch_StateChanged">

Is there any way to find which Switch has been triggered, based on SwitchName, from

private void SfSwitch_StateChanged(object sender, EventArgs e)

{

}

Thank you very much for your help

Hi Codrina,

Thanks for your update.

We have analysed your requirement of "Finding which SfSwitch has been triggered, based on Switch name". Accessing control name in the code behind is not possible at all when control is placed inside DataTemplate. Please find the below link for more information.

Based on that we have prepared a custom sample using AutomationID property also we can find the current state of SfSwitch using IsOn property.

Code snippet

private void SfSwitch_StateChanged(object sender, EventArgs e)
        {
            string automationId = (sender as SfSwitch).AutomationId;
            DisplayAlert(automationId, "Current State : " + (sender as SfSwitch).IsOn, "Ok");
        }

Please find the sample from the below link and let us know if you have any other concerns.
