I'm really struggling with the whole viewmodel and binding to a listview row.

I want to pull data from my sqlite table, and use one of the fields for my text label bound in my listview.

Can someone give me a working example of a binding in a listview pulling just one column from a sqlite table and putting each field on a single row label in the listview?

<listView:ListViewTemplateCell>

<StackLayout BackgroundColor="Bisque" Padding="5" Spacing="5">

<Label Text="{Binding Category}" TextColor="Black" />

</StackLayout>

</listView:ListViewTemplateCell>

How to make a query put each item into that label for rows in my listview?

 

thank you :)

 

I can't even uninstall the "trial" version of telerik for xamarin so I can install the full version.  It only gives me a "restore" option and nothing else.  When I go to manage nuget and try to uninstall it still gives me no options.

So, I can't build this example...

Hello Dan,

The demo uses the Telerik NuGet server for UI for Xamarin. The reason you're having trouble is because you likely have not added the Telerik NuGet server to your NuGet Package Sources. Telerik.UI.For.Xamarin.Trial package is not published to nuget.org, it's published to nuget.telerik.com/nuget.

Fix 

To quickly fix this, go to this documentation and follow the steps in the Visual Studio section.  In short, you're adding the Telerik package source to the Package Sources so that the Package Manager will be able to find (and install) a NuGet package  named "Telerik.UI.For.Xamarin.Trial".


Restore and Build 

Once the package source is there, open the the Package Manager you will be able to find the "Telerik.UI.for.Xamarin.Trial" package,  Here's a screenshot of the Package Manager, notice that I call out the Package source dropdown, This is important because if you have "nuget.org" selected, the UI for Xamairn Package won't listed).



Wrapping Up

Using our NuGet server has the major benefitr that it's much easier to update your project to newer versions of UI for Xamarin when updates are released. It also means that you do not need to install UI for Xamarin to every machine that you use for development.

Let me know if you have any trouble. Worst case scenario, say for example you're behind a firewall that doesn't allow the connection, I can update Yana's demo to use local DLLs instead.

Sorry, I didn't give you enough information.  What I was referring to is that I am working in the NuGet package manager in my Telerik NuGet source and I am trying the following:

I can't uninstall the "trial" version of telerik for xamarin. It only gives me a "restore" option and
nothing else.

When I go to manage nuget and try to uninstall it still gives me no options other than "restore".

I can't install my licensed version because I can't remove the trial version.

 

I managed to get it removed by editing the packages.config files and removing the trial version, and then restarting VS, then install the telerik ui for xamarin.

Thank you again.

Hello all,

I'm just updating this thread with a new version of the demo.

The original demo uses the deprecated PCL project type as well as deprecated project structures for the target platform projects.

The new attached project uses .NETStandard 2.0, Xamarin.Forms 3.4 and the NETStandard-compliant SQLite packages. Visit the official Microsoft Documentation for a full tutorial on how to set up SQLite in a Xamarin.Forms application.

This solution uses UI for Xamarin v 2019.1.220 via Telerik NuGet server and the RadListView is used to display database items. The project has all three target platforms.

Here's a screenshot of the Android project running on a Android 8.1 emulator.
