Combobox with static and dynamic data
binding, combobox, wpf
Solution
CompositeCollection is pretty cool for this. Something like so:
<ComboBox>
<ComboBox.ItemsSource>
<CompositeCollection>
<CollectionContainer Collection="{Binding Source={...whatever...}" />
<ComboBoxItem Name="cbi1">Item1</ComboBoxItem>
<ComboBoxItem Name="cbi2">Item2</ComboBoxItem>
<ComboBoxItem Name="cbi3">Item3</ComboBoxItem>
</CompositeCollection>
</ComboBox.ItemsSource>
</ComboBox>
Problem
I would like to create a combobox that binds to a dynamic resource and has a custom xaml pre-specified list that stays at the top. I know how to bind a combobox to a dynamic resource, ``` <ComboBox Name="comboBox1" Width="Auto" ItemsSource="{Binding}" /> ``` and I know how to insert static items (see WPF - add static items to a combo box ). ``` <ComboBox Text="Is not open"> <ComboBoxItem Name="cbi1">Item1</ComboBoxItem> <ComboBoxItem Name="cbi2">Item2</ComboBoxItem> <ComboBoxItem Name="cbi3">Item3</ComboBoxItem> </ComboBox> ``` but I don't know how to do both at the same time? Note: obviously, there are plenty of different ways to do this with custom widgets and the like, I just feel this should be quite easy somehow.
