Question: how can I get the selected text on the SelectionChanged event of the comboBox
here is my code

```
<ComboBox x:Name="cboRecordType" Margin="2,0" Height="23" Grid.Column="1" VerticalAlignment="Center" SelectionChanged="ComboBox_SelectionChanged">
            <ComboBoxItem Content="Weight"/>
            <ComboBoxItem Content="Height"/>
            <ComboBoxItem Content="Blood Pressure"/>
            <ComboBoxItem Content="Blood Gulocose"/>
        </ComboBox>

```

cboRecordType.Text is empty, didn't cantain the selected Text, how to get that

Answer: 
In the `SelectionChanged` event handler, you can either look at the `cboRecordType.SelectedItem` property on the combobox itself, or you can look at the `AddedItems` property of the `SelectionChangedEventArgs` passed into the event handler. 

When an item is selected, the item is added to the `AddedItems` array property of the event args. (multiple items in a multi select case). When an item is deselected, it is added to the `RemovedItems` array property of the event args.
In your code behind, you need to handle that event like this code: [ComboBox SelectionChanged](http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/1a0bdd27-7faa-4b56-9900-8740c017781a)
 Code Block

```
/// <summary>

/// Handles the comboBox SelectionChanged event

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

private void ComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)

{

}

```
