eventos click dos botoes e imagebutton não funcionam

Question

bom dia pessoal tenho uma pagina onde tenho um repeater que populo com dados da empresa atraves de um datatable ,ate ai tudo bem esta funcionando o problema é que qualquer botão da pagina não funciona o evento click se eu deixar o panel na pagina eu uso o panel no modalextender.

um exemplo no meu codigo eu programei somente este button:abaixo e o evento click não é acionado caso o panel fique na pagina.

                    <asp:ImageButton ID="btnexcel" BorderColor="#000" Width="3%" runat="server" ImageUrl="~/images/Menubotoes/excel1.png"
                        OnClick="excel_click" />

segue meu codigo aspx:

Answer 1

para seu button fucionar ele tem que estar dentro de um updatePanel

---

Não esqueça de usar o componente </> na barra para posta seu código. Microsoft MCPD,MCTS,MCC

Answer 2

bleza entendi mas porque usar o updatePanel qual a moral se meus botões estão fora do meu panel1

Answer 3

Boa Tarde,

Neste caso, utilize o Método ItemCommand do Repeater, cada ação que houver nesses botões, irá disparar esse método. No ItemDataBound do seu repeater vc pode configurar o .CommandName="" e .CommandArgument de cada botão e assim fazer ações necessárias. Segue exemplo:

 protected void SeuRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.DataItem == null) return;

            var x = ((SeuObjeto)e.Item.DataItem);

            ImageButton btn = e.Item.FindControl("ImageButton7") as ImageButton;


            btn.CommandName = "Export";
            btn.CommandArgument = "Valro necssário(ex. Id do Item)";
}

        protected void SeuRepeater_ItemCommand(object source, RepeaterCommandEventArgs e)
        {
            var Id = Convert.ToInt32(e.CommandArgument);


            if (e.CommandName == "Export")
            {
              //Ação necessária 
}
        }

Espero ter ajudado

Abcs

Answer 4

bom dia,os meus imagebuttons não estão dentro do repetidor estão fora ,eu identifiquei o problema mas não entendi o porque,o problema são os <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ErrorMessage="Campo Nome Obrigatorio"
                                    Text="*" ControlToValidate="txtnome"></asp:RequiredFieldValidator> se eu ativar o showmessage do controle funciona os eventos clicks mas da mensagem programada aqui se não não funciona então retirei estas validações e testei ai funcionou .
