[CLOSED] DirectEvents call method codebehind

[rnfigueira]

hi, how to call a server method from client side? (DirectEvents)

[arkilus]

rnfigueira, as far as I know you are not supposed to call DirectEvents from javascript. For this purpose DirectMethods were created.

Recently I had to implement a callback to be called after a drag from a MultiSelect to a GridPanel. In order to achieve that I had to use a "notifyDrop" javascript function, which called a DirectMethod like this:

<script type="text/javascript">
    var notifyDrop_GruposUsuario = function (ddSource, e, data) {
        // etc...

        Ext.net.DirectMethods.InserirUsuarioEmGrupos(codGrupos, {
            success: function(result) {
                Ext.each(data.records, function(record) {
                    addRow(Store_GruposUsuario, record, ddSource);
                });
            },
            failure: function(errorMessage) {
                Ext.Msg.alert('Falha', errorMessage);
            },
            eventMask: {
                showMask: true,
                msg: 'Aguarde...',
                minDelay: 500,
                customTarget: 'GridGruposUsuario'
            }
        });
</script>

and in my .aspx.cs file I have the 'InserirUsuarioEmGrupos' function defined:

    [DirectMethod]
    public string InserirUsuarioEmGrupos(string grupos_json)
    {
        // ...
    }

Consider taking a look at DirectMethods in the Ext.NET Examples Browser.

Hi rnfigueira,
Is arkilus suggestion enough for you? Do you need additional assistance?

[rnfigueira]

ok, thank you

[rnfigueira]

sorry, I have one more question. How do I call this code (notifyDrop_GruposUsuario) from button that is outside of my GridPanel?

[Vladimir]

Sorry, i don't understand last post, please provide more details
Any javascript method can be called by its name

[rnfigueira]

sorry I have not explained the matter well. The situation is as follows. I need to call a method that is the Parent. example:
page1.aspx call page2.asp

page1.aspx

..
<script runat="server">
    [DirectMethod]
    public void LogCompanyInfo(string name, int count)
    {
        string template = string.Concat("{0} has approximately {1} employees.");
        string[] employees = new string[4] { "1-5", "6-25", "26-100", "100+" };
        
        this.Label3.Text = string.Format(template, name, employees[count]);
    }
</script>
..

page2.aspx - here I want to call the method of LogCompanyInfo page1

..
<ext:Button runat="server" Text="Submit">
    <Listeners>
        <Click Handler="?????? Ext.net.DirectMethods.LogCompanyInfo('Ext.NET, Inc.', 0);" />
    </Listeners>
</ext:Button>
..

Try this

<Click Handler="parent.Ext.net.DirectMethods.LogCompanyInfo('Ext.NET, Inc.', 0);" />
