Exception using Pager

[Aaron LeMasters]

Using this code I get an exception "Cannot find column 0"

gridGroupingControl.DataSource = myList;
var pager = new Pager();
pager.PageSize = 100;
pager.Wire(gridGroupingControl);

The "myList" variable is a simple list of custom objects and there are a few hundred records (which display fine if I remove the call to Wire()).

Putting a breakpoint on the call to pager.Wire(...) I see that there are no columns defined in the DataSource.

Exception call stack:

System.IndexOutOfRangeException: Cannot find column 0.

I am not generating the columns. The columns are generated by the control automatically when I assign the DataSource member to the IList. I'm using Syncfusion nuget packages 23.1.38 with .NET 7.0
