    Layout issues with input fields

    Hi there,

    We're using the Ext.NET framework and doing quite good so far, but there's an layout issue (Ext.NET 1.3) which bugs me, because I don't understand when and why this is happening. Scrennshot (FireFox 12.0):

    You can see that the combo box has an ugly layout offset. But this doesn't happen everytime. Sometimes it looks normal (but fails in this simple example). The date field bahaves the same way (right icon has the same ugly offset). I just noticed, that this seams to be a browser issue, it doesn't happen in IE9.

    The code is pretty simple (no custom CSS or Javascript int there):

    <%@ Register assembly="Ext.Net" namespace="Ext.Net" tagprefix="ext" %>
    
    <!DOCTYPE html>
    
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head id="Head1" runat="server">
        <title>Theme Test</title>
    </head>
    <body>
        <form id="form1" runat="server">
            <ext:ResourceManager runat="server" />
    
            <ext:Viewport ID="Viewport1" runat="server" Layout="BorderLayout">
                <Items>
                    <ext:Panel ID="Panel1" runat="server" Region="North" Height="50" Title="Ein Header"></ext:Panel>
                    <ext:Panel ID="Panel2" runat="server" Region="South" Height="50" Title="Ein Footer"></ext:Panel>
                    <ext:Panel ID="Panel3" runat="server" Region="West" Width="100" Title="Links"></ext:Panel>
                    <ext:Panel ID="Panel4" runat="server" Region="East" Width="150" Title="Rechts"></ext:Panel>
                    <ext:Panel ID="Panel5" runat="server" Region="Center" Title="Mitte">
                        <Items>
                            <ext:ComboBox runat="server" ID="theme" EmptyText="" Mode="Local">
                            </ext:ComboBox>
                        </Items>
                    </ext:Panel>
                </Items>
             </ext:Viewport>
        </form>
    </body>
    </html>
    I hope someone give me a hint. Maybe this is a known issue and can be fixed with a line of CSS.

    Thanks in advance
    Regards

    (Temporary) dirty Fix

    I'm failing to find something which is related to this, so I wrote a dirty fix. When I watch at the DOM I see that the clientTop attribute is 1 instead 0, so I fix that by setting a margin of -1. Not nice and not well tested yet, but the wrong layout offset is much uglier...

    (function () {
        var func = function (el) {
            if (this.el.dom.offsetTop == 1)
                this.el.dom.style.marginTop = "-1px";
            else if (this.el.dom.offsetTop == -1)
                this.el.dom.style.marginTop = "0px";
        };
    
        Ext.form.ComboBox.prototype.onResize = Ext.form.ComboBox.prototype.onResize.createSequence(func);
        Ext.form.ComboBox.prototype.onRender = Ext.form.ComboBox.prototype.onRender.createSequence(func);
        Ext.form.DateField.prototype.onResize = Ext.form.DateField.prototype.onResize.createSequence(func);
        Ext.form.DateField.prototype.onRender = Ext.form.DateField.prototype.onRender.createSequence(func);
    })();
