create direct event in runtime to MenuItem

[elbanna23]

Dear All,
I Need your Help
how can i add direct event to MenuItem in Runtime , this is my code :

asp.net Designer

<ext:MenuItem  ID="MenuItem1" runat="server" Width="300" Text="Select Period" Icon="BookOpen">
                    <Menu>
                        <ext:Menu  ID="Menu2" runat="server" BoxMinWidth="300">
                            <Items/>
                            <DirectEvents>
                            <ItemClick OnEvent="SetPeriodSession" />
                            </DirectEvents>
                        </ext:Menu>
                    </Menu>
                </ext:MenuItem>

Code:

public void FillPeriods()
    {
        SqlConnection con = Connections.GetSQLConnection();
        
        string command="SELECT dbo.Schedules.EffectiveDate, dbo.Schedules.ScheduleCode, dbo.Schedules.GroupID,"
        +"dbo.Schedules.PeriodID FROM dbo.Schedules INNER JOIN dbo.Teachers ON dbo.Schedules.TeacherID ="
        +"dbo.Teachers.TID WHERE (dbo.Schedules.TeacherID = @TID)ORDER BY dbo.Schedules.PeriodID";


        SqlCommand com=new SqlCommand(command,con);
        com.Parameters.AddWithValue("@TID", Session["TeacherID"].ToString());
        con.Open();
        SqlDataReader reader = com.ExecuteReader();
        while (reader.Read())
        {
            Ext.Net.MenuItem.Config config = new Ext.Net.MenuItem.Config();
            config.Icon = Icon.BookEdit;
            config.Text = reader[3].ToString();
            config.DirectEvents.Click.ExtraParams.Add(new Ext.Net.Parameter("selected", reader[3].ToString()));
            config.DirectEvents.Click.Event += SetPeriodSession;
            
            
            Menu2.Items.Add(new Ext.Net.MenuItem(config));
        }
        Menu2.DataBind();
        reader.Close();
        con.Close();
    }


    
    public void SetPeriodSession(object o , DirectEventArgs e)
    {
        if (e.Success)
        {
            Session["PeriodNO"] = e.ExtraParams[0].Value;
            SqlConnection con = Connections.GetSQLConnection();
            SqlCommand com = new SqlCommand("select GroupID from Schedules where PeriodID=@PID and TeacherID=@TID and status='Active'", con);
            com.Parameters.AddWithValue("@PID", Session["PeriodNO"].ToString());
            com.Parameters.AddWithValue("@TID", Session["TeacherID"].ToString());
            con.Open();
            SqlDataReader dr = com.ExecuteReader();
            while (dr.Read())
            {
                Session["GroupNO"] = GroupsOperations.GetGroupNo(int.Parse(dr[0].ToString()));
                lblGroupNo.Text = Session["GroupNO"].ToString();
            }
            dr.Close();
            con.Close();
        }
    }

Hi,

I'm not 100% sure where you call the FillPeriods method, but guess during another DirectEvent.

If yes, please see:

I tried More events but it's still not working :(

[Daniil]

Please clarify what do you mean under "More events"?

[elbanna23]

i used (Click & ItemClick) , and tried to work with handler with script :

<script type="text/javascript">
         var getSelectedItem = function (mp) {
             var index = parseInt(mp.getSelIndexField().getValue()),
                item;
             if (!isNaN(index)) {
                 item =menu2.items.get(index);
             }
             alert(item ? item.text : "No selected item");
         };
    </script>

but it's still not working.

Please demonstrate how you use Click and ItemClick events.

Thanks My GOD , I found the Solution :

In Designer no need to create Directevent

 <ext:Menu  ID="Menu2" runat="server" BoxMinWidth="300">
                            <Items/>
                            <%--<DirectEvents>
                            <ItemClick OnEvent="SetPeriodSession" />
                            </DirectEvents>--%>
                        </ext:Menu>

in C# Code i Canceled the Config and Create Ext.Net.MenuItem Directly with a Click Event having a parameter .

    public void FillPeriods()
    {
        SqlConnection con = Connections.GetSQLConnection();
        
        string command="SELECT dbo.Schedules.EffectiveDate, dbo.Schedules.ScheduleCode, dbo.Schedules.GroupID,"
        +"dbo.Schedules.PeriodID FROM dbo.Schedules INNER JOIN dbo.Teachers ON dbo.Schedules.TeacherID ="
        +"dbo.Teachers.TID WHERE (dbo.Schedules.TeacherID = @TID)ORDER BY dbo.Schedules.PeriodID";


        SqlCommand com=new SqlCommand(command,con);
        com.Parameters.AddWithValue("@TID", Session["TeacherID"].ToString());
        con.Open();
        SqlDataReader reader = com.ExecuteReader();
        while (reader.Read())
        {
            Ext.Net.MenuItem mi = new Ext.Net.MenuItem();
            mi.Icon = Icon.BookAdd;
            mi.Text = reader[3].ToString();
            mi.DirectEvents.Click.ExtraParams["PID"]= reader[3].ToString();
            mi.DirectEvents.Click.Event += new ComponentDirectEvent.DirectEventHandler(SetPeriodSession);


            Menu2.Items.Add(mi);
        }
        Menu2.DataBind();
        reader.Close();
        con.Close();
    }


  
    public void SetPeriodSession(object o, DirectEventArgs e)
    {
        Session["PeriodNO"] = e.ExtraParams[0].Value;
            SqlConnection con = Connections.GetSQLConnection();
            SqlCommand com = new SqlCommand("select GroupID from Schedules where PeriodID=@PID and TeacherID=@TID and status='Active'", con);
            com.Parameters.AddWithValue("@PID", Session["PeriodNO"].ToString());
            com.Parameters.AddWithValue("@TID", Session["TeacherID"].ToString());
            con.Open();
            SqlDataReader dr = com.ExecuteReader();
            while (dr.Read())
            {
                Session["GroupNO"] = GroupsOperations.GetGroupNo(int.Parse(dr[0].ToString()));
                lblGroupNo.Text = Session["GroupNO"].ToString();
            }
            dr.Close();
            con.Close();


            ShowAttendance();
    }

Now It's Work
