    Default How to enable/disable a DateField

    How to enable/disable a DateField


    Hi,

    I need to enable/disable a DateField everytime a dropdownlist changes its value.
    I'm trying to call myDateField.disable() method, but it isn't working.
    I'm using version 3.2.1 and this method is listed in documentation (http://www.sencha.com/deploy/dev/doc...form.DateField).

    According to the error message in Firebug, the Method doesn't exists (myDateField.disable is not a function).

    As I'm new to ExtJS, can anyone help me with this?

    Thanks a lot.

    I'd guess that your var myDateField is not referencing what you hope it is referencing.

    But since we see no code, it's impossible to help further.

    Animal,

    Sorry, you are right. I'm using ExtJS with ASP.NET.
    Every TextBox with attribute rel="calendar" will be transformed in a DateField control.
    For now, it's just a simple test page.

    Here is some code:
    ASPX file:
    Code:
    <asp:TextBox ID="txtCalendar" runat="server" rel="calendar"></asp:TextBox>
    JS file:
    Code:
    Ext.onReady(function(){  
        var textBoxes = Ext.DomQuery.select("input[rel=calendar]");  
        
        Ext.each(textBoxes, function(item, id, all){  
            var cl = new Ext.form.DateField({  
                format:      "d/m/Y",
                width:       95,
                applyTo:     item  
            });  
        });
    });
    Code:
    var myDateField = Ext.get("txtCalendar");
    myDateField.disable();
    CrazyEnigma
    I've tried also use myDateField = Ext.get("txtCalendar").dom and myDateField.setDisabled(true);.

    As i said, I'm new to ExtJS, so, I'm not sure if I've done everything the right way.

    Thank you again.

    It's absolutely fundamental that you learn the difference between Ext.get and Ext.getCmp
