How to get children of a WPF container by type?

Question

How can I get the child controls of type ComboBox in MyContainer Grid in WPF?

<Grid x:Name="MyContainer">                         <Label Content="Name"  Name="label1"  />     <Label Content="State" Name="label2"  />     <ComboBox Height="23" HorizontalAlignment="Left" Name="comboBox1"/>     <ComboBox Height="23" HorizontalAlignment="Left" Name="comboBox3" />     <ComboBox Height="23" HorizontalAlignment="Left" Name="comboBox4" /> </Grid> 

This line gives me an error:

var myCombobox = this.MyContainer.Children.GetType(ComboBox); 

Answer 1

This extension method will search recursively for child elements of the desired type:

public static T GetChildOfType<T>(this DependencyObject depObj)      where T : DependencyObject {     if (depObj == null) return null;      for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)     {         var child = VisualTreeHelper.GetChild(depObj, i);          var result = (child as T) ?? GetChildOfType<T>(child);         if (result != null) return result;     }     return null; } 

So using that you can ask for MyContainer.GetChildOfType<ComboBox>().
