Check in the backend if its actually updating the user. If not, then there are bigger issues here. How are you also binding the grid, every page load, or just on the initial page load and during any updates?

Does the text get changed the first time it posts back, but reverts on future postbacks? It may also be the text switch from block to unblock is not be something that automatically saves to viewstate. Therefore, you may need to reassign whether its blocked or unblocked to the linkbutton text on every postback, in RowCreated...

Could you provide some more information about what isn't working?

HTH.
