Question

I have a ComboBoxwith 3 ComboBoxItems each containing an image and text in a stack panel.
I want to bind the SelectedValue to the TextBlock text but can’t just bind to content as this returns the stack panel. How do I bind the SelectedValue to the child TextBlock control? I don’t need to notify anything else I just need the SelectedValue to return the string.

<ComboBox>
  <ComboBoxItem>
    <StackPanel Orientation="Horizontal">
        <Image Source="ImagePath/Image.bmp"/>
        <TextBlock Text="MyTextString"/>
    </StackPanel>
  </ComboBoxItem>
</ComboBox>

SelectedValue is actually property related to binding. in your case you are creating combobox items statically.

check this

in your case you can add Tag property on ComboBoxItem

<ComboBox Height="40" x:Name="cmb" SelectedValuePath="">
            <ComboBoxItem Tag="MyTextString">
                <StackPanel Orientation="Horizontal" >
                    <Image Source="ImagePath/Image.bmp"/>
                    <TextBlock Text="MyTextString"/>
                </StackPanel>
            </ComboBoxItem>
        </ComboBox>

and access it in code

 MessageBox.Show((cmb.SelectedItem as ComboBoxItem).Tag.ToString());
