No, gravity is not affected during a solar eclipse.
I am not quite sure what your question is asking? But let me talk about gravity in a different way.
Einstein showed in 1916 that gravity is an apparent effect produced by a mass distorting space-time in its vicinity. You can think of it as the sun sitting in curved space-time produced by its mass. The effect of this is that the path of light as it passes close to the sun is curved. That is, light no longer moves in a straight line. The APPARENT positions of stars directly behind the sun as seen from earth are changed, because the sun acts like a "gravitational lens." The sun always acts this way, but normally the sun is so bright that we can't see the nearby stars. Measuring the positions of stars close to the sun during an eclipse shows that these positions are no longer the same as when the sun is not in front of these stars. This effect was predicted by Einstein in 1916 and verified during a solar eclipse in 1919 - in fact, it was the first experimental verification of general relativity.
