Good morning,

with the following code:

<sfPopupLayout:SfPopupLayout x:Name="sfPopupLayout_NewDatabase" StaysOpen="True">
<sfPopupLayout:SfPopupLayout.PopupView>
<sfPopupLayout:PopupView ShowHeader="False" ShowFooter="False" WidthRequest="300" HeightRequest="200">
<sfPopupLayout:PopupView.ContentTemplate>
<DataTemplate>
<Grid Padding="16">
<Grid.RowDefinitions>
<RowDefinition Height="30"/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>

<Label x:Name="label_SfPopupLayout_NewDatabase_Title" Grid.Row="0" Text="New database" FontSize="16" FontAttributes="Bold"/>

<sfTextInputLayout:SfTextInputLayout x:Name="sfTextInputLayout_SfPopupLayout_NewDatabase_DatabaseName" Grid.Row="1" ContainerType="Outlined" OutlineCornerRadius="5" FocusedColor="#007bff" ErrorColor="#dc3545" Hint="Database name">
<Entry x:Name="entry_SfPopupLayout_NewDatabase_DatabaseName"/>
</sfTextInputLayout:SfTextInputLayout>

<StackLayout Grid.Row="2" Orientation="Horizontal" HorizontalOptions="End">
<sfButtons:SfButton x:Name="sfButton_SfPopupLayout_NewDatabase_Cancel" Margin="0,10,0,0" CornerRadius="5" HeightRequest="40" BackgroundColor="#6c757d" VerticalOptions="Center" Clicked="SfButton_SfPopupLayout_NewDatabase_Cancel_Clicked" Text="Cancel"/>
<sfButtons:SfButton x:Name="sfButton_SfPopupLayout_NewDatabase_Confirm" Margin="5,10,0,0" CornerRadius="5" HeightRequest="40" BackgroundColor="#007bff" VerticalOptions="Center" Clicked="SfButton_SfPopupLayout_NewDatabase_Confirm_Clicked" Text="Confirm"/>
</StackLayout>
</Grid>
</DataTemplate>
</sfPopupLayout:PopupView.ContentTemplate>
</sfPopupLayout:PopupView>
</sfPopupLayout:SfPopupLayout.PopupView>
</sfPopupLayout:SfPopupLayout>

I would like to get and set "entry_SfPopupLayout_NewDatabase_DatabaseName" value, i would like to access to controls like inside the MainPage, how can i do that?

Hi Marco,

Thanks for contacting Syncfusion support.

In SfpopupLayout, we can not explicitly access the controls that are hosted inside of PopupView. In these cases, we suggested that the MVVM be used to set or get the value for that control in the code behind.

Please follow the code example,

 
[XAML]
<
ContentPage.BindingContext> 
        <local:ViewModel x:Name="viewModel"/> 
</ContentPage.BindingContext> 
…. 
 
<Entry x:Name="entry_SfPopupLayout_NewDatabase_DatabaseName" Text="{Binding BookName}"/>
…..
 
       
[.CS] 
public MainPage() 
{ 
    InitializeComponent(); 
    viewModel.BookName = "PopupLayout Book"; 
}                      
 
We hope this helps, please let us know If need further assistance from us.

Regards, 
Karthik Raja
