    [CLOSED] Triggers created in code behind - help

    Hi,

    I am able to create trigger from code behind. Is it possible to fire server side events with triggers? Please check the code, and add code behind event.

    Hi,

    I would suggest you to use DirectMethod.

    Please look at the example.

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        ComboBox c = new ComboBox()
        {
            Items =
            {
                new Ext.Net.ListItem("item1", "1"),
                new Ext.Net.ListItem("item2", "2")
            }
        };

        FieldTrigger ft = new FieldTrigger()
        {
            Icon = TriggerIcon.Clear,
            Tag = "clear"
        };
        c.Triggers.Add(ft);

        c.Listeners.TriggerClick.Handler = "Ext.net.DirectMethods.TriggerClick(tag, index);";

        this.Form.Controls.Add(c);
    }

    [DirectMethod]
    public void TriggerClick(string tag, int index)
    {
        X.Msg.Alert("TriggerClick", index + " " + tag).Show();
    }
</script>

    Thanks... works perfect for me. To add clear button, like this example (Item Actions):

    https://examples2.ext.net/Form/ComboBox/Items_Actions/

                    cboCombo = new ComboBox ( );
                cboCombo.Store.Add (store);
                cboCombo.ID = "cboLista" + i.ToString();
                cboCombo.AllowBlank = false;
                    FieldTrigger ftCombo = new FieldTrigger()
                    {
                        Icon = TriggerIcon.Clear,
                        Tag = "Remove selected"
                    };
                    cboCombo.Triggers.Add(ftCombo);

                    cboCombo.Listeners.TriggerClick.Handler = "this.clearValue();";
                    
                cboCombo.AutoWidth = true;
                cboCombo.Editable = false;

                frmEditorPaso.Items.Add(cboCombo);
    Thanks!!!
