comboBox add-in property

[helenchu]

All,
I'm trying unsuccessfully to make my comboBox to show all items in its dropdown portion.  I used
DropDownHeight, MinDropDownItems ="5"  None worked. 

Thanks for your help

You can find the optional attributes to add to the Config.esriaddinx for your combobox here:
Add-in Combobox schema

The following will set the max dropdown rows to 10:

<ComboBox id="My_TestCombo" 
          class="TestCombo" 
          message="Add-in command generated by Visual Studio project wizard." 
          caption="Test ComboBox" 
          tip="Add-in command tooltip." 
          category="Add-In Controls"
          rows="10"
          image="Images\TestCombo.png" />
