    [CLOSED] Form: check if it's dirty

    Hello,

    I want to check if a form was modified so I use the IsDirty method like this

     
tab.getBody().formPanel.isDirty()
    Unfortunatelly it always return true even if no modification was made to the form. Is it a bug? Or how can I check is the form was modified or not?

    Romuald.

    Hello,
    Here is an example. It's not complete but it gives you the structure

    First of all I have a TabPanel with the following code

    <ext:TabPanel ID="MainTab" runat="server">
    <Listeners>
       <BeforeTabClose Fn="confirmTabClose" />
    </Listeners>
</ext:TabPanel>
    Tabs are added to this TabPanel in javascript with the following code

    Ext.getCmp(?MainTab?).addTab({
                        id: id,
                        title: 'titre',
                        closable: true,
                        autoLoad: {
                            showMask: true,
                            url: url,
                            mode: 'iframe',
                            noCache: true,
                            scripts: true
                        }
                    });
    The beforetabClose calls the following function. In this function I want to check the isDirty of the form

     
function confirmTabClose(tab){
      tab.getBody().formPanel.isDirty()
}
    Each Tab is defined as follow

    <ext:FormPanel ID="formPanel" runat="server" Url="url">
 <Items>
?
</Items>
</ext :FormPanel>
    Thanks,
    Romuald.

    Hi,

    We need iframe page source code. As you can see in my example 'isDirty' method works corretly. Please provide iframe page which is loaded inside tab

    Hello,

    I already provide the iframe code. It was the code I gave at the end of my previous thread and meant each frame is defined as follow.
    Here is it again

    <ext:Viewport ID="viewPort" runat="server" Layout="Fit">
        <Items>
            <ext:FormPanel ID="formPanel" runat="server" Url=?url">
                  <Items>
?
</Items>
</ext :FormPanel>
   </Items>
</ext:Viewport

    Hi,

    I don't see any fields inside FormPanel. Do you check empty FormPanel?

    Hi,

    Here is a new version

     
<ext:Viewport ID="viewPort" runat="server" Layout="Fit">
        <Items>
            <ext:FormPanel ID="formPanel" runat="server" Url=?url">
                  <Items>
<ext:TabPanel ID="tabPanel" runat="server" DeferredRender="false">
                            <ext:Panel ID="tabNote" Title="Titre" runat="server"
                                BodyStyle="padding: 6px;" Layout="Fit">
                                <Items>
                                    <ext:TextArea ID="fieldNote" DataIndex="Note" FieldLabel="label"
                                        runat="server" AnchorHorizontal="100%">
                                    </ext:TextArea>
                                </Items>
                            </ext:Panel>
</ext:TabPanel>
</Items>
</ext :FormPanel>
   </Items>
</ext:Viewport

    Hi,

    I cannot reproduce the issue.

    Can you modify my sample to demonstrate the problem?
