Get one element from an ItemsControl and binding to a Button - wpf

Question

I have an ItemsControl:
<ItemsControl x:Name="myList" ItemTemplateSelector="{DynamicResource mySelectorTemplate}" ItemsPanel="{StaticResource myPanelTemplate}"/>
I want to take one of the items and make a button with his logic:
<Button Style="{StaticResource myButtonStyle}"/>
One of the items of myList has a boolean with true value. This is the item with which the button will be made:
Private myCollection As ObservableCollection(Of Items.Subitems)
myList.ItemsSource = myCollection
When myCollection.myBooolean = true, is the field that gives to the item this special treatment.
What would be an efficient way to do this?

There are many possibilitys for this - but this looks like the best way.
You want to use a DataTemplateSelector. You can choose n DataTemplates with this by your own overwritten logic.
C#
Sample Class:
public class MySampleClass
{
public string Name;
public bool MyFlag;
}
Sample Template Selector
public class MyTemplateSelector : DataTemplateSelector
{
public DataTemplate IsTrueTemplate
{
get;
set;
}
public DataTemplate IsFalseTemplate
{
get;
set;
}
public override DataTemplate SelectTemplate(object item, DependencyObject container)
{
MySampleClass temp = item as MySampleClass;
if(temp != null)
{
if (temp.MyFlag)
{
return IsTrueTemplate;
}
else
{
return IsFalseTemplate;
}
// And so on
}
else
{
return base.SelectTemplate(item, container);
}
}
}
Usage in XAML
<ListBox>
<ListBox.ItemTemplateSelector>
<example:MyTemplateSelector>
<example:MyTemplateSelector.IsTrueTemplate>
<DataTemplate>
<StackPanel>
<Button Style="{StaticResource myButtonStyle}" />
<TextBlock Text="{Binding Name}" />
</StackPanel>
</DataTemplate>
</example:MyTemplateSelector.IsTrueTemplate>
<example:MyTemplateSelector.IsFalseTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}" />
</DataTemplate>
</example:MyTemplateSelector.IsFalseTemplate>
</example:MyTemplateSelector>
</ListBox.ItemTemplateSelector>
</ListBox>
example is your DataTemplateSelector-Namespace.
I would recommend you - to store the DataTemplates in the Resources and set it via StaticResource.
