L'événement datagrid_itemcommand ne se déclenche pas

Question

J'utilise une grille de données dans mon format qui a 2 boutons, éditer et supprimer mais l'événement pour ceux-ci ne se déclenche pas. Où vais-je mal dans le code. J'ai couru le même code dans vb.net mais après la conversion en C#, ça ne marche pas. Plz aide.

Y a-t-il d'autres changements que je dois faire lors de la conversion du code de vb.net en C# ?? Merci d'avance!

private void dgjob_ItemCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e) 
{ 
    try 
    { 
     switch (e.CommandName) 
     { 
      case "edit": 

       try 
       { 

        qry = "select ROLE from AV_USER_DETAILS where USER_ID='" + Session["user_name"] + "'"; 
        cmd.Connection = con; 
        cmd.CommandText = qry; 
        con.Open(); 
        if (Information.IsDBNull(cmd.ExecuteScalar())) 
        { 
         av_class.alert("User Not Permitted ", this); 
         con.Close(); 
         return; 

        } 
        string st = cmd.ExecuteScalar().ToString(); 
        if (!(st == "hod") & !(st == "Media_Planner")) 
        { 
         av_class.alert("User Not Permitted ", this); 
         con.Close(); 
         return; 


        } 
        con.Close(); 
        if (st == "hod")

       { 
        av_class.alert("Ro's are Created for this !So can't be Edited", this); 
        return; 
       } 


       if (chk_job(ViewState["job_code"].ToString()) == false) 
       {

        //Exit Sub 
        tb_campaign.Enabled = false; 
       }

Dans votre fichier ASPX, vous appelez nulle part méthode « dgjob_ItemCommand » où vous événement attendez à faire virer.

vous devez appeler "dgjob_ItemCommand" sur l'événement OnSelectedIndexChanged de la grille.

<asp:datagrid id="dgjob" runat="server" CssClass="davpdgdatagrid" 
        PageSize="100" AutoGenerateColumns="False" ShowFooter="True" 
        BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" 
        BorderWidth="1px" CellPadding="4" ForeColor="Black" GridLines="Horizontal" 
        HorizontalAlign="Center" OnSelectedIndexChanged="dgjob_ItemCommand"> 
         <AlternatingItemStyle CssClass="davpdgalt"></AlternatingItemStyle> 

J'espère que cela aide.
