what are grandparents rights in TEXAS i am an grand paretns that can't see my grandson?

See a lawyer, but most places have no grand parents rights.

Texas does allow for grandparent rights in "some" circumstances. Not all. Expect to have to hire a lawyer to fight for your rights. You can't do it on your own.

They normally would be that if the parents are together and choosing not to let you see the child, that is their choice. Grandparent rights generally only come into play when the parents separate, one parent dies or goes to jail, or a previously established relationship with the child (like they lived with you before or some such).

Texas requires that grandparents meet the harm standard in order to win visitation.

Each US State has their own laws on this. In Texas, the rights are very limited.

The parent has the superior right, including the right to decide who does and does not have access to their child.

Grandparents may file suit requesting custody if they believe it is in the child's best interest.

I Texas, if grandparents don't already have possession of the child or if the parent is not incarcerated or deceased, they don’t have too much to go on.

The parents divorced;

The parent abused or neglected the child;

The parent has been incarcerated, found incompetent, or died;

A court-order terminated the parent-child relationship; or

The child has lived with the grandparent for at least six months.

The parent has the superior right, including the right to decide who does and does not have access to their child.

Per comment, I know its visitation, but laws are aimed at custody.

I 'll move the last line to the top.

MOST states don't formally recognize "grandparent's rights". In the few that do, they require a preexisting actual relationship. Being a biological relative is not sufficient.

You should have been a better parent.

You have no visitation rights.
