Infragistics WebCombo Get the Value of Cell by Column Name

Get the Value in a Cell by the Column Name

To get the value in a Infragistics WebCombo cell by the column name (in this case, column DrugName):

string chosenName = e.Row.Cells.FromKey("DrugName").ToString;

where e is the EventArgs from

protected void igWebCombo1_SelectedRowChanged(object sender,
Infragistics.WebUI.WebCombo.SelectedRowChangedEventArgs e)

I had previously gotten the value using an index value:
string chosen = e.Row.Cells[2].Value.ToString().Trim();

but in continuing development, the number of columns may vary, and therefore the index may change.
