Use single Template for multiple Item Sources and render separate combobox in UI

I am new to WPF/XAML so I am stuck in one problem is it possible that if I create one TEMPLATE of combobox in UI and what if is it possible to use one ComboBox to render multi-item sources? For example, I have two item sources A and B and in XAML I have one common template. So is it possible that I can create two different ComboBox in UI for A and B from single template?
I am using below template for creation
<ComboBox x:Name="comboboxtemplate" ItemsSource="{Binding CboItemsource}" SelectedItem="{Binding comboboxSelecteditem, Mode=TwoWay}"
Visibility="{Binding ShowCombobox, UpdateSourceTrigger=PropertyChanged}" Width="{Binding ComboboxWidth, UpdateSourceTrigger=PropertyChanged}"
IsEnabled="{Binding FieldValueIsEditable, UpdateSourceTrigger=PropertyChanged}"
IsTextSearchCaseSensitive="False"
IsTextSearchEnabled="True"
TextSearch.TextPath="Description">
<ComboBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Code}" Width="0"/>
<TextBlock Text= "{Binding Description}" TextWrapping="Wrap" />
</StackPanel>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>

You could create a style that you apply to both ComboBoxes, .e.g.:
<Window x:Class="WpfApplication1.Window1"
...>
<Window.Resources>
<Style x:Key="cmbStyle" TargetType="ComboBox">
<Setter Property="Visibility" Value="{Binding ShowCombobox, UpdateSourceTrigger=PropertyChanged}" />
<Setter Property="IsEnabled" Value="{Binding FieldValueIsEditable, UpdateSourceTrigger=PropertyChanged}" />
<Setter Property="IsTextSearchEnabled" Value="True" />
<!-- ... -->
<Setter Property="ItemTemplate">
<Setter.Value>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Code}" Width="0"/>
<TextBlock Text= "{Binding Description}" TextWrapping="Wrap" />
</StackPanel>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<StackPanel>
<ComboBox x:Name="cmb1" ItemsSource="{Binding CboItemsource}"
SelectedItem="{Binding comboboxSelecteditem, Mode=TwoWay}"
Style="{StaticResource cmbStyle}" />
<ComboBox x:Name="cmb2" ItemsSource="{Binding OtherItemsource}"
SelectedItem="{Binding OtherSelecteditem, Mode=TwoWay}"
Style="{StaticResource cmbStyle}" />
</StackPanel>
</Window>

WPF Add more interaction to listview items

I am binding my listview to a viewmodel using Caliburn. My view's code is the following:
<ListView x:Name="ListView" Grid.Row="1" Grid.ColumnSpan="2" ItemsSource="{Binding ProjectsPMod}" Margin="110,0,110,131" HorizontalContentAlignment="Stretch" BorderThickness="0" Height="111" VerticalAlignment="Bottom">
<interactivity:Interaction.Triggers>
<interactivity:EventTrigger EventName="SelectionChanged">
<cal:ActionMessage MethodName="OpenProjectShell">
<cal:Parameter Value="{Binding ElementName=ListView, Path=SelectedItem}" />
</cal:ActionMessage>
</interactivity:EventTrigger>
</interactivity:Interaction.Triggers>
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel>
<StackPanel Orientation="Horizontal">
<ContentControl Content="{StaticResource Appbar_Suitcase}" />
<Label Content="{Binding Name}"/>
</StackPanel>
<Separator HorizontalAlignment="Stretch" Margin="0, 10, 0, 0"/>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Right now each item in every row just displays its name and a briefcase icon. If I wanted to add an "Edit"further down that row, where if you clicked on it something happened (perhaps a popup appears), how would I do it?

You can make an ordinary Button look like a link using a template. Just add a Button to your StackPanel and bind it to a command:
<ListView x:Name="ListView" Grid.Row="1" Grid.ColumnSpan="2" ItemsSource="{Binding ProjectsPMod}" Margin="110,0,110,131" HorizontalContentAlignment="Stretch" BorderThickness="0" Height="111" VerticalAlignment="Bottom">
<interactivity:Interaction.Triggers>
<interactivity:EventTrigger EventName="SelectionChanged">
<cal:ActionMessage MethodName="OpenProjectShell">
<cal:Parameter Value="{Binding ElementName=ListView, Path=SelectedItem}" />
</cal:ActionMessage>
</interactivity:EventTrigger>
</interactivity:Interaction.Triggers>
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel>
<StackPanel Orientation="Horizontal">
<ContentControl Content="{StaticResource Appbar_Suitcase}" />
<Label Content="{Binding Name}"/>
</StackPanel>
<Separator HorizontalAlignment="Stretch" Margin="0, 10, 0, 0"/>
<Button Margin="0 10 0 0" Content="Link" Cursor="Hand" Command="{Binding YourCommand}">
<Button.Template>
<ControlTemplate TargetType="Button">
<TextBlock TextDecorations="Underline">
<ContentPresenter />
</TextBlock>
</ControlTemplate>
</Button.Template>
<Button.Style>
<Style TargetType="Button">
<Setter Property="Foreground" Value="Blue" />
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Foreground" Value="Red" />
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
You can control the position of the Button within the StackPanel using its Margin property.

If you mean "How to add an edit button for each row?" then you simply need to add a button in the ItemTemplate:
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel>
<StackPanel Orientation="Horizontal">
<ContentControl Content="{StaticResource Appbar_Suitcase}" />
<Label Content="{Binding Name}"/>
<!-- Edit button -->
<Button Command="{Binding EditCommandOnViewModel}" Content="Edit" />
</StackPanel>
<Separator HorizontalAlignment="Stretch" Margin="0, 10, 0, 0"/>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>

WPF: Prevent ComboBox from displaying selected item

I have a ComboBoxthat I have templated to look like this:
Here is the XAML for this ComboBox:
<ComboBox Name="StateInclusionRules_ComboBox"
ItemsSource="{Binding StateInclusionRules}"
Height="25"
Width="155"
Margin="0"
Grid.Column="7">
<ComboBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal"
Margin="0">
<Label Content="{Binding State}"
Margin="0,0,0,0"
Width="30" />
<CheckBox IsChecked="{Binding StateTax}"
Margin="20,0,0,0"/>
<CheckBox IsChecked="{Binding StateChildSupport}"
Margin="30,0,0,0"/>
</StackPanel>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
Is there a way to prevent the selected item from being displayed in the ComboBox ContentPresenter (the red bordered area, i.e, the area you see when the ComboBox is closed)?

First you need 2 DataTemplates, 1 for the selected item and 1 for the drop down item.
The selected we are going to leave empty because this is your requirment.
The drop down item DataTemplate will have the exact DataTemplate you wanted.
When item is selected a DataTrigger will change it's template to the SelectedTemplate, like so:
<Window.Resources>
<DataTemplate x:Key="DropDownItemTemplate" DataType="wpfApplication1:ItemSourceModel">
<StackPanel Orientation="Horizontal"
Margin="0">
<Label Content="{Binding Value}"
Margin="0,0,0,0"
Width="30" />
<CheckBox IsChecked="{Binding Value}"
Margin="20,0,0,0"/>
<CheckBox IsChecked="{Binding Value}"
Margin="30,0,0,0"/>
</StackPanel>
</DataTemplate>
<DataTemplate x:Key="SelectionBoxTemplate">
</DataTemplate>
<DataTemplate x:Key="ComboBoxTemplate">
<ContentPresenter x:Name="Presenter"
Content="{Binding}"
ContentTemplate="{StaticResource DropDownItemTemplate}" />
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor,ComboBoxItem,1}}" Value="{x:Null}">
<Setter TargetName="Presenter" Property="ContentTemplate" Value="{StaticResource SelectionBoxTemplate}" />
</DataTrigger>
</DataTemplate.Triggers>
</DataTemplate>
</Window.Resources>
And set your ComboBox with the ComboBoxTemplate:
<ComboBox Name="StateInclusionRules_ComboBox"
ItemsSource="{Binding YourItemSource}" ItemTemplate="{StaticResource ComboBoxTemplate}"
Height="25"
Width="155"
Margin="0"
/>

PivotItems do not resize after binding

I am binding a PivotItems but somehow the items are not resized properly, according to my margin declaration. Why is that?
EDIT: here is my new code and it still has gaps..
<Pivot x:Name="TpsSegmentsPivot" Title="Locator" Foreground="#FF888888" Style="{StaticResource PivotStyle1}" SelectionChanged="Pivot_SelectionChanged" Margin="0" Grid.Row="1" ItemTemplate="{StaticResource TpTemplate}" ItemsSource="{Binding DataSource}">
<Pivot.HeaderTemplate>
<DataTemplate>
<Grid>
<TextBlock Text="{Binding id}" Margin="0, 16, 0, 0" Foreground="#FF888888" FontSize="32" FontFamily="Segoe WP" FontWeight="Light"/>
</Grid>
</DataTemplate>
</Pivot.HeaderTemplate>
</Pivot>
This is the template:
<DataTemplate x:Key="TpTemplate">
<ListBox Background="Black"
ItemsSource="{Binding Seg}"
ItemTemplate="{StaticResource SectionUCTemplate}"
HorizontalAlignment="Stretch"
VerticalAlignment="Top">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
</DataTemplate>
Here is a screenshot with the red pivotItem..

I think the issue with the extra space is the Piviot Item you are using inside the DataTemplate tag. remove it and bind the header to a header template. I've used data binding on Pivots before and never seen this issue.
From one of my released apps:
<controls:Pivot Title="CAMPING CHECKLIST" ItemsSource="{Binding FilteredCategories}" Name="MainPivot">
<controls:Pivot.HeaderTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}" />
</DataTemplate>
</controls:Pivot.HeaderTemplate>
<controls:Pivot.ItemTemplate>
<DataTemplate>
<!-- Your pivot item content here -->
</DataTemplate>
</controls:Pivot.ItemTemplate>
</controls:Pivot>
I believe the PivotItem in a PivotItem is the root of your issue.
your code should look similar to:
<controls:Pivot ItemsSource="{Binding tripTypeViewModel.TripTypeViewModelDataSource}" x:Name="TripsSegmentsPivot" Title=" " Foreground="#FF888888" Style="{StaticResource PivotStyle1}" SelectionChanged="Pivot_SelectionChanged" Grid.Row="1">
<controls:Pivot.HeaderTemplate>
<DataTemplate>
<TextBlock Text="{Binding DataContext.tripTypeViewModel.HeaderText, ElementName=TripsSegmentsPivot}" Margin="0, 16, 0, 0" Foreground="#FF888888" FontSize="32" FontFamily="Segoe WP" FontWeight="Light"/>
</DataTemplate>
</controls:Pivot.HeaderTemplate>
<controls:Pivot.ItemTemplate>
<DataTemplate>
<ListBox x:Name="ItemsLB" ItemsSource="{Binding DataContext.tripTypeViewModel.Segment, ElementName=TripsSegmentsPivot}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Background="Transparent">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<local:SectionUC HorizontalAlignment="Stretch" Grid.Row="1" VerticalAlignment="Top"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</DataTemplate>
</controls:Pivot.ItemTemplate>
</controls:Pivot>
The first image is how I describe it, the second is how you currently have it :

This is the standard behaviour for PivotItems since they are always displayed with a margin. You should set a negative margin:
margin="-20,0,-20,0"

DataBinding ListView creating components if a certain condition is met

I am working on a C# WPF project and I have a list view which uses data binding and a collection view.
Below is how my ListView is currently populated.
<ListView HorizontalAlignment="Left" Margin="547,12,0,41" Name="lstCallLogInformation" Width="320">
<ListView.Style>
<Style TargetType="ListView">
<Style.Triggers>
<Trigger Property="HasItems" Value="False">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListView">
<TextBlock Text="No items in your devices call log" FontWeight="Bold" HorizontalAlignment="Center" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
</ListView.Style>
<ListView.GroupStyle>
<GroupStyle>
<GroupStyle.ContainerStyle>
<Style TargetType="{x:Type GroupItem}">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Expander IsExpanded="True">
<Expander.Header>
<StackPanel Orientation="Horizontal">
<TextBlock FontWeight="Bold" Foreground="Gray" Text="{Binding Name}" VerticalAlignment="Bottom" />
</StackPanel>
</Expander.Header>
<ItemsPresenter />
</Expander>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</GroupStyle.ContainerStyle>
</GroupStyle>
</ListView.GroupStyle>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="Control.HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate>
<DataTemplate>
<DockPanel Style="{StaticResource onmouseover}">
<StackPanel HorizontalAlignment="Stretch" Orientation="Horizontal" Tag="{Binding logID}">
<Image Height="30" Source="{Binding base64ImageString, Converter={StaticResource ImageConverter}}" Width="30" />
<StackPanel Margin="10" Orientation="Vertical">
<TextBlock FontWeight="Bold" Text="{Binding contactNameOrPhoneNumber}" />
<StackPanel HorizontalAlignment="Stretch" Orientation="Horizontal">
<TextBlock HorizontalAlignment="Left" Text="{Binding dateString}" />
<TextBlock Margin="15, 0, 0, 0" Text="Duration: " />
<TextBlock HorizontalAlignment="Right" Text="{Binding humanReadableCallDuration}" />
</StackPanel>
</StackPanel>
<StackPanel Orientation="Vertical">
<Button Background="Transparent" BorderThickness="0" BorderBrush="Transparent" Tag="{Binding logID}" Name="btnAddAsContact" Click="btnAddAsContact_Click">
<Image Width="15" Height="15" Source="/BoardiesSMSServer;component/images/add.png" Tag="{Binding logID}" />
</Button>
<Button Background="Transparent" BorderThickness="0" BorderBrush="Transparent" Tag="{Binding logID}" Name="btnDeleteContactFromLog" Click="btnDeleteContactFromLog_Click">
<Image Width="15" Height="15" Source="/BoardiesSMSServer;component/images/delete.png" Margin="0,0,0,5" Tag="{Binding logID}" />
</Button>
</StackPanel>
</StackPanel>
</DockPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Within my DockPanel within the DataTemplate I have a StackPanel which contains various TextBlocks from the array that is passed into the binding.
In one of the StackPanels you will see you will see a TextBlock that binds to the element of contactNameOrPhoneNumber.
What I want to be able to do is if another value from the binding is null then I add a TextBlock for the contactNameOrPhoneNumber` element and alongside it have another TextBlock which contains another element of number``, if the other binding value is not null then this extra textblock of number is not added.
So in simple terms, what I want to be able to do is within the DataTemplate have a conditional if statement of if binding value == null add textblock to stackpanel else don't add textblock.

You can do that with Style + Triggers something like this:
<TextBlock>
<TextBlock.Style>
<Style TargetType="TextBlock">
<Style.Triggers>
<DataTrigger Binding="{Binding PropertyName}" Value="{x:Null}">
<Setter Property="Visibility" Value="Collapsed"/>
</DataTrigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
Also you can create IValueConverter say ObjectToVisibilityConverter which will take input your property and if property is null return Visibility.Collapsed else return Visibility.Visible.
You can then bind property with Visibility value of TextBlock via Converter.
<TextBlock Visibility="{Binding PropertyName,
Converter={StaticResource ObjectToVisibilityConverter}}"/>
