display a UserControl when click Button

I have created a ListViewTemplate as a UserControl,that I want to display it when I click on this Hamburger Button,this is my code:
Main.xaml:
<SplitView.Content >
<Grid Background="White" >
<Grid.RowDefinitions>
<RowDefinition Height="35" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid Grid.Row="0" Background="#f0f0f0" >
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
<Button x:Name="TrieButton" Margin="0" Content=""
Width="50" Background="Transparent" VerticalAlignment="Stretch" Click="TrieButton_Click" />
</StackPanel>
</Grid>
<Frame Grid.Row="1" x:Name="ContentFrame" Margin="0" />
</Grid>
</SplitView.Content>
And this is the code Behind:
Main.xaml.cs:
private void TrieButton_Click(object sender, RoutedEventArgs e)
{
ListViewTemplate c = new ListViewTemplate();
if (c.Visibility == Visibility.Visible)
{
c.Visibility = Visibility.Collapsed;
}
else
{
c.Visibility = Visibility.Visible;
}
}
this is my UserControl:
ListViewTemplate.xaml:
<Grid x:Name="FilterGrid" Background="Black">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right" Margin="0" >
<ListView x:Name="Liste" Background="Black" >
<ListViewItem >
<TextBlock Text="Nom" Foreground="#9d9e9e"/>
</ListViewItem>
<ListViewItem >
<TextBlock Text="Catégorie" Foreground="#9d9e9e"/>
</ListViewItem >
</ListView>
</StackPanel>
</Grid>
My problem is that this ListView UserControl is not shown when I click on the TrieButton,even I have increased the height of Grid
so please How can I correct my code,to have Listview showed when I click on TrieButton
thanks for help

Firstly: You didn't add the UserControl to your main XAML anywhere. You should add to XAML first like this:
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:usercontrol="clr-namespace:WpfApplication1"
Then:
<Grid Background="White" x:Name="MGrid">
<Grid.RowDefinitions>
<RowDefinition Height="35" />
<RowDefinition Height="10" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid Grid.Row="0" Background="#f0f0f0" >
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
<Button x:Name="TrieButton" Margin="0" Content=""
Width="50" Background="Transparent" VerticalAlignment="Stretch" Click="TrieButton_Click" />
</StackPanel>
</Grid>
<Frame Grid.Row="1" x:Name="ContentFrame" Margin="0" />
<usercontrol:ListViewTemplate x:Name="c" Grid.Row="2" Visibility="Collapsed"></usercontrol:ListViewTemplate>
</Grid>
Secondly: You just created a new instance of a ListViewTemplate. You should find one that is placed in your XAML by using FindName method and then change the Visibility of it like this:
private void TrieButton_Click(object sender, RoutedEventArgs e)
{
ListViewTemplate c = MGrid.FindName("c") as ListViewTemplate;
c.Visibility = c.Visibility == Visibility.Visible ? Visibility.Collapsed : Visibility.Visible;
}

In response to the button click you are incorrectly creating a new instance of a ListViewTemplate object and then throwing it away.
I think that what you really want to do is something along these lines:
private void TrieButton_Click(object sender, RoutedEventArgs e)
{
ListViewTemplate c = (ListViewTemplate) Controls["Liste"];
if (c.Visibility == Visibility.Visible)
c.Visibility = Visibility.Collapsed;
else
c.Visibility = Visibility.Visible;
}
Here we retrieve the existing Control and change its visible/collapsed state.

how to get listboxitem's value on listbox hold event?

xmal code:
<ListBox x:Name="listbox2" Margin="0,0" SelectionChanged="listbox2_SelectionChanged" Hold="listbox2_Hold" >
<ListBox.ItemContainerStyle >
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<Border BorderThickness="0,0,0,1" BorderBrush="Gray">
<Grid Width="auto" HorizontalAlignment="Stretch" >
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock VerticalAlignment="Center" FontSize="40" Grid.Column="1" Grid.Row="0" Foreground="White" Text="{Binding NAME}"></TextBlock>
<TextBlock VerticalAlignment="Center" FontSize="25" Grid.Column="1" Grid.Row="1" Foreground="Blue" Text="{Binding PHONE}"></TextBlock>
<Image Name="c1" HorizontalAlignment="Left" VerticalAlignment="Top" Width="100" Height="100" Stretch="Fill" Margin="0" Source="{Binding IMGS}" Grid.RowSpan="2" Grid.Column="0" />
</Grid>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
class list which is bind to list box is
List < contactsclass > contacts = new List < contactsclass >();
PHONE and NAME are getter setter of the contactclass's variables
how can i get this variable's value on hold event of listbox .. i am trying following code
private void listbox2_Hold(object sender, System.Windows.Input.GestureEventArgs e)
{
//contextmenucontact = (contactsclass)(sender as ListBox).DataContext;
contextmenucontact = (contactsclass)listbox2.SelectedItem;
MessageBox.Show(contextmenucontact.name);
}

if is just the selected item is just use the ToString Function, see this:
if (listBox1.SelectedItem != null)
{
string itemText = listBox1.SelectedItem.ToString();
contextmenucontact = new contactsclass();
contextmenucontact.name = itemText;
MessageBox.Show(contextmenucontact.name);
}

Out of memory exception while using <ScrollViewer> with multiple ListViews in it

I have a usercontrol with 2 ListViews in it. One for holding a list of predefined categories and one for the list with all the categories in it.
When i place the ListViews inside a <Grid> than everything works perfect.
The working xaml code (with Grid):
<Grid Style="{StaticResource ResourceKey=ContentStyle}">

</Grid>
The only problem with this is that I dont get the UI behaviour that I want. If I use a grid then only the red border is scrollable (because of the ListView). But what I need is that the entire green border is scrollable.
So I want to put everything in a <ScrollViewer><StackPanel></StackPanel></ScrollViewer>.
But when I do so, I occasionally get an out-of-memory exception (sometimes the apps just freezes and close without an exception).
Here is my not working xaml with the <ScrollViewer>:
<ScrollViewer>
<StackPanel>
<ListView x:Name="lstPredefinedCategories" ItemsSource="{Binding PredefinedCategories}" SelectionMode="Multiple" Margin="20">

Any thoughts on why my app is freezing or get an OOM-exception?
Update
It comes because in the 2nd ListView they are too much objects loaded. So I'm gonna try to fix it with ISupportIncrementalLoading.
Or is there an other way?

The solution was to use virtualization (ISupportIncrementalLoading) like suggested in the comments.
Here you can find my implementation class of ISupportIncrementalLoading:
public class StringKeyValueIncrementalCollection : ObservableCollection<StringKeyValue>, ISupportIncrementalLoading
{
private List<StringKeyValue> allCategories;
private int lastItem = 1;
public StringKeyValueIncrementalCollection(List<StringKeyValue> categories)
{
this.allCategories = categories;
}
public bool HasMoreItems
{
get
{
if (lastItem == allCategories.Count)
{
return false;
}
else
{
return true;
}
}
}
public IAsyncOperation<LoadMoreItemsResult> LoadMoreItemsAsync(uint count)
{
CoreDispatcher coreDispatcher = Window.Current.Dispatcher;
return Task.Run<LoadMoreItemsResult>(async () =>
{
List<StringKeyValue> items = new List<StringKeyValue>();
for (int i = 0; i < count; i++)
{
items.Add(allCategories[i]);
lastItem++;
Debug.WriteLine(lastItem);
if (lastItem == allCategories.Count)
{
break;
}
}
await coreDispatcher.RunAsync(CoreDispatcherPriority.Normal,
() =>
{
foreach (StringKeyValue item in items)
{
this.Add(item);
}
});
return new LoadMoreItemsResult() { Count = count };
}).AsAsyncOperation<LoadMoreItemsResult>();
}
}
And then my code in the ViewModel. As you can see, I use the StringKeyValueIncrementalCollection instead of a regular List<object>:
private StringKeyValueIncrementalCollection categories;
private StringKeyValueIncrementalCollection allCategories;
public StringKeyValueIncrementalCollection Categories
{
get { return categories; }
set
{
filteredCategories = value;
RaisePropertyChanged("Categories");
}
}
public async void LoadCategories()
{
List<StringKeyValue> temp = await this.openVlaanderenService.GetCategoriesData();
allCategories = new StringKeyValueIncrementalCollection(temp);
Categories = allCategories;
}
The only problem that you than have is that the ScollViewer will allow it's content to fill as much space as it wants, so the data just will keep loading. To fix that I did what was suggested in ISupportIncrementalLoading inside ScrollViewer not supported?
So I added a SizeChanged="ScrollViewer_SizeChanged" event to my ScrollViewer and in code behind set the size of the ListView based on the viewport size properties of the ScrollViewer:
private void ScrollViewer_SizeChanged(object sender, SizeChangedEventArgs e)
{
lstCategories.Height = scrollViewer.ViewportHeight;
}

Bind ItemsSource to Column of ComboBoxes

As per title. The column is in a DataTemplate.
This is what I have currently:
var test = FindChildControl<ComboBox>(this, "PrintCode") as ComboBox;
test.ItemsSource = listPrintCode;
MessageBox.Show(test.Items.Count.ToString());
FindChildControl method:
private DependencyObject FindChildControl<T>(DependencyObject control, string ctrlName)
{
int childNumber = VisualTreeHelper.GetChildrenCount(control);
for (int i = 0; i < childNumber; i++)
{
DependencyObject child = VisualTreeHelper.GetChild(control, i);
var fe = child as FrameworkElement;
// Not a framework element or is null
if (fe == null) return null;
if (child is T && fe.Name == ctrlName)
{
// Found the control so return
return child;
}
DependencyObject nextLevel = FindChildControl<T>(child, ctrlName);
if (nextLevel != null)
return nextLevel;
}
return null;
}
XAML - Template

<ComboBox x:Name="PrintCode" Grid.Row="0" Grid.Column="2" ItemsSource="{Binding}"
SelectedValuePath="PrintCode" DisplayMemberPath="PrintCode"/>
<CheckBox Grid.Row="0" Grid.Column="3" IsChecked="{Binding PrintShortSerial}"/>
</Grid>
</DataTemplate>
XAML - ListBox that implements the Template
<telerik:RadListBox Grid.Row="0" Grid.Column="2" Margin="0, 5, 5, 5"
x:Name="listBoxIssue" HorizontalAlignment="Left" VerticalAlignment="Top"
Height="690" Width="793"
ItemTemplate="{StaticResource lbIssueTemplate}" ItemsSource="{Binding}"
SelectionMode="Multiple" Drop="ListBoxIssue_OnDrop"/>
The message box is just simply to confirm that 'listPrintCode' and 'FindChildControl' is working as intended. But the ComboBox didn't display anything, even if it's just 1 ComboBox. If I apply the codes to a normal ComboBox not part of the template, it's all fine. I think there's an obvious flaw in my code, which is that there's nothing that seems to apply to all ComboBoxes in the column. So my question is, how do I bind my ItemsSource as the column of the comboboxes?
Note: The number of rows (ComboBoxes) are not fixed.

Grid height not adjusting properly when a row height with SharedSizeGroup changes

I have two grids with three rows each. The first and last row of each grid has a fixed height while the middle rows have auto height and share their height using SharedSizeGroup.
First, the content of the right grid determines the height of the size group. When the content of the right grid shrinks so that the content of the left grid determines the height of the size group, the overall size of the left grid is not adjusted correctly.
See the following sample app. Click the increase button to increase the size of the textblock in the right grid. The size of the left grid changes accordingly. Now decrease the size. When the textblock becomes smaller than the textblock in the left grid, the total size of the left grid doesn't shrink. Is this a bug or am i missing something?
<StackPanel Orientation="Horizontal" Grid.IsSharedSizeScope="True">
<StackPanel Orientation="Vertical" Width="100">
<Grid Background="Green">
<Grid.RowDefinitions>
<RowDefinition Height="15" />
<RowDefinition SharedSizeGroup="Group1" />
<RowDefinition Height="15" />
</Grid.RowDefinitions>
<TextBlock Background="Blue" Grid.Row="0" />
<TextBlock Background="Red" Grid.Row="1" Name="textBlock1" Height="100" />
<TextBlock Background="Blue" Grid.Row="2" />
</Grid>
<TextBlock Text="{Binding Path=ActualHeight, ElementName=grid1}" />
</StackPanel>
<StackPanel Orientation="Vertical" Width="100">
<Grid Background="Green">
<Grid.RowDefinitions>
<RowDefinition Height="15" />
<RowDefinition SharedSizeGroup="Group1" />
<RowDefinition Height="15" />
</Grid.RowDefinitions>
<TextBlock Background="Blue" Grid.Row="0" />
<TextBlock Background="Red" Grid.Row="1" Name="textBlock2" Height="150" />
<TextBlock Background="Blue" Grid.Row="2" />
</Grid>
<TextBlock Text="{Binding Path=ActualHeight, ElementName=grid2}" />
</StackPanel>
<Button Height="24" Click="Button_Click_1" VerticalAlignment="Top">Increase</Button>
<Button Height="24" Click="Button_Click_2" VerticalAlignment="Top">Decrease</Button>
</StackPanel>
private void Button_Click_1(object sender, RoutedEventArgs e)
{
textBlock2.Height += 30;
}
private void Button_Click_2(object sender, RoutedEventArgs e)
{
textBlock2.Height -= 30;
}

The rows are staying the same height - the size of the second TextBlock is changing, while the size of the first TextBlock remains 100.
To demonstrate this, make the following changes:
Add ShowGridLines="True" to each of your Grids
Change your named TextBlocks to show their ActualHeight as their text:
<TextBlock Background="Red" Grid.Row="1" Name="textBlock2" Height="150"
Text="{Binding RelativeSource={RelativeSource Self}, Path=ActualHeight}"/>
You will see that the SharedSizeGroup row will be the maximum ActualHeight of the two TextBlocks.
Update: A Short Project To Show What's Happening
I've created a quick-n-dirty project to show what's happening. It turns out that when the right grid gets smaller than the original size, the left grid does an Arrange but not a Measure. I am not sure I understand this completely - I have posted a follow-up question with this same solution.
Here is the solution that I created, based on your original. It simply wraps the basic grid in a custom class that spews out info (via event) when Measure and Arrange are called. In the main window, I just put that info into a list box.
InfoGrid and InfoGridEventArgs classes
using System.Windows;
using System.Windows.Controls;
namespace GridMeasureExample
{
class InfoGrid : Grid
{
protected override Size ArrangeOverride(Size arrangeSize)
{
CallReportInfoEvent("Arrange");
return base.ArrangeOverride(arrangeSize);
}
protected override Size MeasureOverride(Size constraint)
{
CallReportInfoEvent("Measure");
return base.MeasureOverride(constraint);
}
public event EventHandler<InfoGridEventArgs> ReportInfo;
private void CallReportInfoEvent(string message)
{
if (ReportInfo != null)
ReportInfo(this, new InfoGridEventArgs(message));
}
}
public class InfoGridEventArgs : EventArgs
{
private InfoGridEventArgs()
{
}
public InfoGridEventArgs(string message)
{
this.TimeStamp = DateTime.Now;
this.Message = message;
}
public DateTime TimeStamp
{
get;
private set;
}
public String Message
{
get;
private set;
}
}
}
