Washington (CNN) -- President Obama toasted a growing U.S. friendship with India at the first state dinner of his administration Tuesday, an evening of regal pageantry and symbolic politics in a tent on the White House South Lawn.



"To the future that beckons all of us," Obama said with glass raised toward his guest of honor, visiting Indian Prime Minister Manmohan Singh. "Let us answer its call. And let our two great nations realize all the triumphs and achievements that await us."



A tradition dating back to 1874, state dinners are the most treasured and formal honor a U.S. president can offer a foreign dignitary, and the most coveted invitation in Washington.



The Tuesday night dinner showed Obama's intention to signal strong ties with the world's largest democracy and go his own way in navigating the pomp and tradition of White House customs.



Traditionally, a new administration's first invitation goes to the leader of neighboring Canada or Mexico, though recent presidents also haven't followed that precedent.



The event planned by first lady Michelle Obama emphasized eco-friendly themes such as White House-grown herbs and lettuce served to guests and sustainably harvested magnolia branches -- from species native to both India and the United States -- in arrangements adorning the tent where more than 300 guests wearing tuxedos and gowns were wined, dined and entertained.



A White House document said common themes of state and official visits are "forging friendships, exchanging knowledge and building bridges that last for years."



In a toast that followed Obama's, Singh praised his host's leadership and prompted applause by citing the charm of the U.S. first lady.



Obama's election was "an inspiration to all those who cherish the values of diversity, democracy and equal opportunity," Singh said, adding that India "warmly applauded" the Nobel Peace Prize awarded Obama this year for "the healing touch you have provided and the power of your idealism and your vision."



"We need to find new pathways of international cooperation that respond more effectively to the grave challenges caused by the growing interdependence of nations," Singh said. "As two leading democracies, India and the United States must play a leading role in building a shared destiny for all humankind."



Obama, in a black tuxedo, and the first lady, in a dazzling cream gown with silver accents, greeted Singh and his wife, Gursharan Kaur, as they arrived, shaking hands on the White House steps and posing for pictures before leading their guests inside.



Guests in tuxedos and evening gowns streamed into the White House for the historic social event, passing a line of journalists. In one humorous mishap, the cummerbund of Sen. Bob Casey, a Pennsylvania Democrat, fell off as he and his wife walked in.



The guest list included political allies, a few opponents, celebrities and members of the Indian diplomatic community.



Secretary of State Hillary Clinton made the list, but not her husband, former President Bill Clinton. Democratic colleagues of the president including other Cabinet ministers, several senators and top aides made the list, including Sen. John Kerry of Massachusetts (but not his wife, Teresa Heinz Kerry), House Speaker Nancy Pelosi, Sen. Claire McCaskill of Missouri, White House Press Secretary Robert Gibbs and White House Budget Director Peter Orszag.

A couple of Republicans also made it, notably Indiana Sen. Richard Lugar and Louisiana Gov. Bobby Jindal.



Celebrities included Hollywood director Steven Spielberg, actors Alfre Woodard and Blair Underwood, CBS News anchor Katie Couric and New York Times columnist Tom Friedman.



However, one name rumored to be included, but not appearing on the list, was Oprah Winfrey.



The dinner, in a tent set up on the White House South Lawn with a view of the Washington Monument, featured round tables for 10 set in resplendent colors -- apple green, ruby, gold -- with floral arrangements of roses, hydrangeas and sweet peas in plum, purple and fuchsia.



Place settings in fine china from three previous administrations -- Eisenhower, Clinton and George W. Bush -- were flanked by five pieces of silverware and crystal
