    [CLOSED] CommandColumn and DirectEvents

    I have a GridColumn with 2 CommandColumn and a Listener:

    	....
	....
	<ColumnModel ID="ColumnModel1" runat="server">
	   <Columns>
		   ....
		   <ext:CommandColumn Width="30">
			   <Commands>
				  <ext:GridCommand CommandName="Command1" />
			   </Commands>
		   </ext:CommandColumn>
		   <ext:CommandColumn Width="30">
			   <Commands>
				  <ext:GridCommand CommandName="Command2" />
			   </Commands>
		   </ext:CommandColumn>
	   </Columns>
	</ColumnModel>

	<Listeners>
	   <Command Fn="commandHandler" />
	</Listeners>
	....
	....
    This is the listener:

        <script type="text/javascript">
        var commandHandler = function (cmd, record) {
            switch (cmd) {
                case "Command1":
                ....
                                                               break;
                                                               
                case "Command2":
                ....
                                                               break;
            }
        }
    </script>
    I need to replace the Listener with a DirectEvent, but how can I associate a specific DirectEvent (with a specific Url) to each CommandButton?
    There isn' an Fn attribute for Command...

    Thanks,
    Stefano

    Hello, jmcantrell!

    I don't know what solution was there.
    But if you just want to handle commands on server side I would suggest you to use direct methods.

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

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

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            Store store = this.GridPanel1.Store.Primary;
            store.DataSource = new object[] { 
                                         new object[] {"test1"},
                                         new object[] {"test2"},
                                         new object[] {"test3"}
                                };
            store.DataBind();
        }
    }

    [DirectMethod]
    public void Command1_Handler()
    {
        X.Msg.Alert("Hello!", "Command1_Handler").Show();
    }

    [DirectMethod]
    public void Command2_Handler()
    {
        X.Msg.Alert("Hello!", "Command2_Handler").Show();
    }
</script>

                    Ext.net.DirectMethods.Command1_Handler();
                    break;
