radlistview filling available space and scrolling correctly isn't possible?

with a xamarin forms listview, all you had to do was add a footer and it would fill space and scroll just fine.

 

Is there no option in radlistview to provide that functionality?

Whether you can support reading excel and read the data to DataSet or DataTable, you can set up 100 or 100 entries at a time to improve efficiency

Busy animation won't display when setting IsBusy = false

I am having trouble displaying the BusyIndicator in my project. Here's my XAML:

<?xml version="1.0" encoding="UTF-8"?>
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:telerikListView="clr-namespace:Telerik.XamarinForms.DataControls.ListView;assembly=Telerik.XamarinForms.DataControls"
             xmlns:telerikDataControls="clr-namespace:Telerik.XamarinForms.DataControls;assembly=Telerik.XamarinForms.DataControls"
             xmlns:iconize="clr-namespace:FormsPlugin.Iconize;assembly=FormsPlugin.Iconize"
             xmlns:upTimeMobile="clr-namespace:UpTimeMobile;assembly=UpTimeMobile.Android"
             xmlns:lc="clr-namespace:XLabs.Forms.Controls;assembly=XLabs.Forms"
             xmlns:lb="clr-namespace:XLabs.Forms.Behaviors;assembly=XLabs.Forms"
             xmlns:lcon="clr-namespace:XLabs.Forms.Converter;assembly=XLabs.Forms"
             xmlns:lp="clr-namespace:XLabs.Forms.Pages;assembly=XLabs.Forms"
             xmlns:telerikBusyIndicator="clr-namespace:Telerik.XamarinForms.Primitives;assembly=Telerik.XamarinForms.Primitives"
             xmlns:sys="clr-namespace:System;assembly=mscorlib"
             x:Class="MyApp.Views.Details">
    <telerikBusyIndicator:RadBusyIndicator x:Name="BusyIndicator"
                                           AnimationType="Animation6"
                                           AnimationContentColor="DodgerBlue"
                                           AnimationContentHeightRequest="100"
                                           AnimationContentWidthRequest="100"
                                           IsBusy="True">
        <telerikBusyIndicator:RadBusyIndicator.Content>
         
            <!-- Radlist goes here... -->
             
        </telerikBusyIndicator:RadBusyIndicator.Content>
    </telerikBusyIndicator:RadBusyIndicator>
</ContentPage>

 

This works, and the busy animation appears on the screen. However, if I try to set the indicator to false, the busy indicator doesn't appear at all when the content page is loading. Here's my code:

[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class Details : ContentPage
{
    public Details(Guid Id, string name)
    {
        InitializeComponent();
         
        BusyIndicator.IsBusy = true;
        DoLoad();
        BusyIndicator.IsBusy = false;
    }
     
    private void DoLoad()
    {
        // do data load here...
        ListViewDetails.ItemsSource = results;
    }
}

 

I also tried using async like this (but still doesn't work):

private async void DoLoad()
{
    await Task.Run(() =>
    {
        // do data load here...
        ListViewDetails.ItemsSource = results;
    });
}

 

My Android project min version is 6.0 (23), target is 6.0 (23), compiled using 8.0. I'm using Telerik UI for Xamarin R3 2017 and I also have SkiaSharp.Views.Forms 1.59.2 installed.

object sender and ItemSwipeCompletedEventArgs e are NULL or just returning an Object instead of data

I'm having an issue with my RadListView ItemSwipeCompleted method.  I've followed the instructions in the documentation but the example data retrieval code does not work in my project.

Here's my code:

                <telerikDataControls:RadListView x:Name="categoriesListview" ItemsSource="{Binding Source}" HeightRequest="200" WidthRequest="500"
                                                 ItemTapped="CategoryRadListView_OnItemTapped"
                                                 IsItemSwipeEnabled="True"
                                                 ItemSwipeCompleted="OnItemSwipeCompleted"
                                                 SwipeOffset="10"
                                                 SwipeThreshold="20"
                                                 BackgroundColor="GhostWhite"
                                                 >
                    <telerikDataControls:RadListView.ItemTemplate>
                        <DataTemplate>
                            <listView:ListViewTemplateCell>
                                <listView:ListViewTemplateCell.View>
                                    <Grid>
                                        <Label Margin="10" Text="{Binding Category}" Font="{DynamicResource text_size}" />
                                    </Grid>                                    
                                </listView:ListViewTemplateCell.View>
                            </listView:ListViewTemplateCell>
                        </DataTemplate>
                    </telerikDataControls:RadListView.ItemTemplate>
                    <telerikDataControls:RadListView.ItemSwipeContentTemplate>
                        <DataTemplate>
                            <Grid Margin="0"
                              Padding="0"
                              ColumnSpacing="0"
                              RowSpacing="0">
                            <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="100" />
                            </Grid.ColumnDefinitions>
                            
                            <Label
                               BackgroundColor="Red"
                               HorizontalTextAlignment="Center"
                               Text="delete"
                               TextColor="White"
                               VerticalTextAlignment="Center"
                               WidthRequest="100" />
                            </Grid>
                        </DataTemplate>
                    </telerikDataControls:RadListView.ItemSwipeContentTemplate>
                </telerikDataControls:RadListView>

 

The RadListView is working fine, it's ONLY the itemswipe that I can't see any data...

 

Here's my code behind for the ItemSwipeCompleted event:

        public void OnItemSwipeCompleted(object sender, ItemSwipeCompletedEventArgs e)
        {
            try
            {
                var row = sender as RadListView;
                var item = (sender as BindableObject).BindingContext as groceryList;
                row.EndItemSwipe();

                statusLabel.Text = "item: " + item + " sender: " + row;
            }
            catch (Exception ex)
            {
                statusLabel.Text = "Sender: " + sender + " Error: " + ex.ToString();
            }            
        }

 

sender is just the RadListView control object and item is NULL.

Appointment appears in wrong cell

I have an appointment that has a start and end time of 23:00 and 23:59 respectively.

If the start and end date are 28th Oct. 2017, the appointment appears in the cell for the 29th.

If the start and end date are 29th Oct. 2017, the appointment doesn't appear at all.

If the start and end date are 30th Oct. 2017, the appointment appears in the correct cell.

29th October 2017 was when the clocks went forward in the UK. Perhaps this is effecting something?

Also, if the time is set before 23:00, the appointment appears in two cells in month view.

And when the appointment is in the wrong cell, day view shows the appointment as spanning the whole day.

This seems like a bug.

RadListview Item Selection and Deselction

Hi,

I have implemented a RadListview with Selection mode Multiple.

when user select an Item the Item is selecting as per the selection mode and selection Gesture which is fine.

But now I have a scenario to some items to not select when user try to select it even selection mode is enabled, instead it should be in deselection mode. It should check the flag from Itemsource  of the listview Item and disable that Item programatically it should show a toast message like which is not selectable.

Help me out to implement this scenario and suggest me the approaches if any.

 

Thanks,

AutoCompleteEditor & Custom class

Hy,

is any way, for DataForm and EditorType.AutoCompleteEditor, that AutoCompleteEditor has list of custom class and not list of string?


Example:

I have classes for Book and Worker, I would like to use for author AutoComplete whick have list of WorkerRecord.

public class BookRecord{

    [DataSourceKey("BookName")]
    string Name;

    [DataSourceKey("Author")]
    WorkerRecord author;
}

public class WorkerRecord{
    string Name;
    string Surname;
}

 

this.dataForm.RegisterEditor("BookName", EditorType.TextEditor);
this.dataForm.RegisterEditor("Author", EditorType.AutoCompleteEditor);

 

Tnx for all information.

Regards,
Jernej

Errors when building Xamarin Android (with Forms)
I have exactly the same issue - 38 errors similar to this one:

```
1: Error obj/Debug/android/src/mono/com/telerik/android/primitives/widget/sidedrawer/DrawerChangeListenerImplementor.java (8,51):  error: package com.telerik.android.primitives.widget.sidedrawer does not exist
com.telerik.android.primitives.widget.sidedrawer.DrawerChangeListener
```

I have Xamarin.Forms version 2.5.0.91635 which was released ~2-3 weeks ago. 

Here is is my packages.config with Android Support and Forms packages:

```
<package id="Xamarin.Android.Support.Animated.Vector.Drawable" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.Annotations" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.Compat" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.Core.UI" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.Core.Utils" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.Design" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.Fragment" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.Media.Compat" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.Transition" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.v4" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.v7.AppCompat" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.v7.CardView" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.v7.MediaRouter" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.v7.Palette" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.v7.RecyclerView" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Android.Support.Vector.Drawable" version="25.4.0.2" targetFramework="monoandroid71" />
<package id="Xamarin.Forms" version="2.5.0.91635" targetFramework="monoandroid71" />
```

I all the required DLLs (for ListView) manually:

```xml
<Reference Include="Telerik.Xamarin.Android.Common, Version=2017.3.1123.0, Culture=neutral, PublicKeyToken=null">
  <HintPath>..\Libs\Telerik.UiForXamarin\Android\Telerik.Xamarin.Android.Common.dll</HintPath>

</Reference>
```

What am I missing?
