How can I binding the checked SfRadio button in a SfRadioButtonGroup to an enum?

[Thanh Hai Dang]

Hi,

I'm using SfRadioButton and SfRadioButtonGroup.

How can I create a group and binding value of an button in group to an enum?

For example, I have a group radio button contains 7 radio buttons describe 7 days of weeks. How can I bind the value of the checked radio button to a variable instead of using 7 variables?

Thanks and best regards,

TH

Hi Thanh Hai Dang,

Greetings from Syncfusion support!

Query: How can I bind the value of the checked radio button to a variable instead of using 7 variables?

In response to your query, we recommend using the SelectedValue property from the SfRadioGroup, as shown in the code snippet below. This approach will help you avoid binding multiple variables to individual RadioButton components. 

Code snippet:

<StackLayout>

    <HorizontalStackLayout Spacing="5" HorizontalOptions="Center">

        <Label Text="Selected Item: " FontAttributes="Bold"/>

        <Label Text="{Binding SelectedItem}" />

    </HorizontalStackLayout>

    <buttons:SfRadioGroup x:Name="radioButton" SelectedValue="{Binding SelectedItem}" CheckedChanged="OnCheckedChanged">

        <buttons:SfRadioButton Text="Sunday" Value="Sunday"/>

        …

        <buttons:SfRadioButton Text="Saturday" Value="Saturday"/>

    </buttons:SfRadioGroup>

</StackLayout>

By using this method, you can easily retrieve the selected value from the radio button group and bind it to a single variable.

For more detail, please refer to below help documentation:

For your convenience, we have attached a sample project demonstrating this approach. We encourage you to review the sample and integrate this method into your application.

Hi  Brundha V,

Thank you for your effort. I'm using Syncfusion version 26.2.4 and seem the SelectedValue property in SfRadioGroup and Value property in SfRadioButton haven't defined yet.

What the minimum version can I use with the properties?

Thanks and best regards,
