[Reza]

I have an accordion that i am populating data from a viewmodel. How would i expand one accordion from the viewmodel? 

As an example, i am populating an accordion with weekly data sunday - saturday, I want to expand the accordion to whatever day today is, say Tuesday.

Hi Reza, 

 

Thank you for using Syncfusion products. 

 

We have checked the reported query from our end. We would like to let you know that you can expand one AccordionItem based on IsExpanded property by using ExpandMode as Single when loaded. Please find the following code snippet for more reference, 

 

Xaml: 

 

<accordion:SfAccordion x:Name="accordion" 

                               BindableLayout.ItemsSource="{Binding Info}"  

                               ExpandMode="Single"> 

            <BindableLayout.ItemTemplate> 

                <DataTemplate> 

                    <accordion:AccordionItem IsExpanded="{Binding IsExpanded}"> 

                        <accordion:AccordionItem.Header> 

                            <Grid> 

                                <Label Grid.Row="0" 

                                        Text="{Binding Name}" 

                                        TextColor="Black" 

                                        FontAttributes="Bold" 

                                        FontSize="20" /> 

                            </Grid> 

                        </accordion:AccordionItem.Header> 

                        <accordion:AccordionItem.Content> 

                            <Grid HeightRequest="50"> 

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

                            </Grid> 

                        </accordion:AccordionItem.Content> 

                    </accordion:AccordionItem> 

                </DataTemplate> 

            </BindableLayout.ItemTemplate> 

        </accordion:SfAccordion>
