I need to create a ComboBox with a multi selection function and I saw in the documentation that the UltraComboBox and the UltraComboBoxEditor have a property called CheckedListSettings.
Unfortunately when I try to set up this property in my application the Compiler simply says that I don't have it this property ...
My version of Win Infragistics is the 8.1 and the assembly in the class are:
using Infragistics.Win;
using Infragistics.Win.Misc;
using Infragistics.Win.UltraWinEditors;
This property was added in a much later version than you are using. If you want to use this feature, you will need to update to the latest version.
Or, you could create your own multi-select combo using a technique similar to this:
HOWTO:Creating a Multi-Select Dropdown Combo for the WinGrid
In order to upgrade to the latest version of your control set do we need to purchase a new license or do you automatically upgrade the toolset when a future is missing?
Great. Thanks Mike for the clarification, I appreciated.
I'm pretty sure you would need to purchase an upgrade from v8.1 to get this new feature - unless you own a license with a subscription.
But you might want to contact Infragistics Sales and double-check on that. :)
