    radio button always returns false

    This may sounds stupid but if I check if the radio button is checked it always returns false. How do I check which radio button in a group has been selected?


    Front-end Code:
    
<ext:Radio runat="server" ID="Always2" GroupName="CLOccurance2" FieldLabel="Always" InputValue="Always" AnchorHorizontal="85%" Width="60" />
<ext:Radio runat="server" ID="Sometimes2" GroupName="CLOccurance2" FieldLabel="Sometimes" InputValue="Sometimes"  AnchorHorizontal="85%" Width="60" />
    Codebehind:
    /** Both of the following returns false **/
        String radioChecked1 = Always2.Checked.ToString();
        String radioChecked2 = Sometimes2.Checked.ToString();
    Thank you.:confused:

    Example

    <%@ Page Language="C#" %>
 
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
 
<script runat="server">
    protected void Button1_Click(object sender, DirectEventArgs e)
    {
        string val1 = this.Radio1.Checked.ToString();
        string val2 = this.Radio2.Checked.ToString();
        
        X.Msg.Notify("Text", string.Format("{0} : {1}", val1, val2)).Show();
    }
</script>

    Thank you for the reply. Looking at your code I realized that it wasn't working because of the way I was calling the method:

     <ext:Button ID="Button1" runat="server" Text="Save" Icon="Accept">
                    <Listeners>
                        <Click Handler="if (#{FormPanel1}.getForm().isValid()) {Ext.net.DirectMethods.SubmitNewCourse();}else{Ext.Msg.show({icon: Ext.MessageBox.ERROR, msg: 'Please check the fields and try again!', buttons:Ext.Msg.OK});}" />
                    </Listeners>
                </ext:Button>

     public void SubmitNewCourse()
    {
        String radioChecked1 = Always2.Checked.ToString();
        String radioChecked2 = Sometimes2.Checked.ToString();
}
    If I use onDirectClick on the button then change the method to have "object sender, DirectEventArgs e" it works fine.

    Can I still have validation like I have it above and make it work?

    The following code doesn't work. Not sure what the correct way of doing it is:

     <ext:Button ID="Button1" runat="server" Text="Save" Icon="Accept">
                    <Listeners>
                        <Click Handler="if (#{FormPanel1}.getForm().isValid()) {Ext.net.DirectMethods.SubmitNewCourse;}else{Ext.Msg.show({icon: Ext.MessageBox.ERROR, msg: 'Please check the fields and try again!', buttons:Ext.Msg.OK});}" />
                    </Listeners>
                </ext:Button>

     public void SubmitNewCourse(object sender, DirectEventArgs e)
    {
        String radioChecked1 = Always2.Checked.ToString();
        String radioChecked2 = Sometimes2.Checked.ToString();
}

    DirectEvent with Form Validation

    Now that it works, it looks quite simple... and I feel stupid.

    Thank you for the help. You can mark this as solved.

    Thanks for the update. Glad to hear it's working for you now.

    In future forum posts, providing a full .aspx code sample, similar to the sample I posted above, will give us a better idea of your scenario and let us see all the moving parts. Posting snippets of code picked from the page will not get the whole message across.
