Controle Executando eventos de outros controle.

Question

Caros colegas, alguém sabe me informar como configurar o controle para que ele execute somente o evento pertencente a ele?

Por exemplo: Eu seleciono um item no DropDownList e um evento é disparado

Quando eu seleciono outro item em outra DropDownList na mesma página, primeiro é disparado o evento da primeira DropDownList para em seguida executar o evento da segunda DropDownList quando deveria ser executado somente o evento da segunda DropDownList.

 Private Sub cod_nivel1_ni1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles cod_nivel1_ni1.SelectedIndexChanged
        Session("cod_nivel1_ni1") = cod_nivel1_ni1.SelectedValue
       
    End Sub

    Private Sub Ano_TextChanged(sender As Object, e As EventArgs) Handles Ano.TextChanged
        Session("AnoRes") = Ano.Text

        objGeracaoResiduo.IndicadoresSSMAGerarDados(cod_nivel1_ni1.SelectedValue, Ano.Text)
    End Sub

Grato

Answer 1

Oliciel Cortes,

Você deve ter mantido selecionado mais de um controle quando adicionou o event handler. O comportamento normal é disparar para apenas o controle que estava selecionado quando adicionou o tratamento para o evento.

Faça uma varredura em seu código pois outros controles devem estar fazendo referência explícita ao mesmo método.

Answer 2

Juliano obrigado pela pronta resposta, creio que seja algo de configuração e não sei onde alterar, pois esse problema apareceu recentemente e está acontecendo em todas as páginas.

Aqui está o código da página onde identifiquei o problema.

Se estiver ao seu alcance em ajudar ficarei grato.

Answer 3

Pelo aspx não está sendo associado o evento (via atributos de tags)? Verifique se há algum JavaScript tratando o evento do dropdown e disparando uma mudança na seleção incorretamente.

Na verdade o JavaScript está tratando o TextBox.
