    [CLOSED] CheckBoxGroup - RadioGroup validate()

    Hi all,

    what is asked here:

    http://extjs.com/forum/showthread.ph...ckbox+validate

    is what I'm searching for. Is there a way now to check if at least one Checkbox or Radio is checked in its group container?

    If not, can you suggest a way to solve this, by client side.

    Thanx a lot

    Matteo

    P.S. a validateGroup() function would really be great! :)

    Hi Matteo,

    You can set AllowBlank="false" for Group.
    Please see the following example:
    <%@ Page Language="C#" %>
<%@ Register Assembly="Coolite.Ext.Web" Namespace="Coolite.Ext.Web" TagPrefix="ext" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
    
    protected void Page_Load(object sender, EventArgs e)
    {
    }

</script>

<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
    <title>Example</title>
</head>
<body>
    <form id="Form1" runat="server">
        <ext:ScriptManager ID="ScriptManager1" runat="server" />
        
        <ext:CheckboxGroup 
            ID="CheckboxGroup1" 
            runat="server" 
            AllowBlank="false"
            Vertical="true"
            ColumnsNumber="1"
            Width="200"
            MsgTarget="Title"
            FieldLabel="Auto Layout">
            <Items>
                <ext:Checkbox ID="Checkbox4" runat="server" BoxLabel="Item 1" />
                <ext:Checkbox ID="Checkbox5" runat="server" BoxLabel="Item 2" />
                <ext:Checkbox ID="Checkbox6" runat="server" BoxLabel="Item 3" />
                <ext:Checkbox ID="Checkbox7" runat="server" BoxLabel="Item 4" />
                <ext:Checkbox ID="Checkbox8" runat="server" BoxLabel="Item 5" />
            </Items>
        </ext:CheckboxGroup> 
        
        <ext:Button runat="server" Text="Validate">
            <Listeners>
                <Click Handler="#{CheckboxGroup1}.validate();" />
            </Listeners>
        </ext:Button>
    </form>
</body>
</html>

    Hi Vlad,

    ok, sorry for some reason I forgot the AllowBlank property, I built it at runtime.
    Now works fine, confirm it is solved.

    Thank you

    Matteo
