usually if you want to delete a register in list, when you try, a new window appears, asking --> if you want to delete, this X registers ??? ( in case you activated X registers), if you click in the button. the register appears.. Now in other list, I don´t know why... but in a list I have some registers. and if i mark one register to delete, a new window appear asking me.. "select some rows for deletion" with a Agree button.. I click in the button to try to delete.. but the register don´t dissapear, don´t do nothing... If you see.. the question is different.. the usual question is .. if you want to delete x registers.. and now in this list is askinng me for select some rows for deletion, when a registers is activated. after this, the button is not working. why can not delete the register??? maybe there is any trouble in the code of any element ??? because i can not see any mistake, but i can not delete the registers.. Any suggestions? Thanks in advance!
