Wow this was more complicated than i imagined, but I did get it to work great! thanks. This was my final version. The TextKey contains the data you want to turn into columns, and the TextValue is the value that ends up inside each cell.

DECLARE @cols AS NVARCHAR(MAX),
        @query AS NVARCHAR(MAX)


select @cols = STUFF((SELECT distinct ', ' + QUOTENAME(TextKey) 
                    from #SourceTbl
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

set @query = 'SELECT FromEntityID, DisplayName, ' + @cols + ' 
              FROM 
              (
                  select FromEntityID, DisplayName, TextKey, TextValue
                  from #SourceTbl
              ) x
              pivot 
              (
                  min(TextValue)
                  for TextKey in (' + @cols + ')
              ) p 
              ORDER BY FromEntityID
              '

execute(@query)
