Hello Mark

You are looking for properties off the IGPullDownCell class.  (http://help.infragistics.com/iOS/2016.1/igapi/Classes/IGGridViewPullDownCell.html)  Most specifically the pullDownText, ReleaseText, and updatingText.

In our help documentation is a walkthrough demonstrating how to modify this text (http://help.infragistics.com/iOS/2016.1/?page=IGGridView_Enabling_Configuring_Pull_Down_Reload.html) .  On this page is  a link for "Customize Pull Down Cell"

Hope this helps.

Mark,

Here's a quick Xamarin.iOS sample I made up to demonstrate changing the text messages. If you need something more detailed, you'll want to use the documentation Darrell provided to derive your own pull down cell.
