    [CLOSED] slider in a formpanel

    Hi,

    I had taken the demo of a slider and got it working in a panel.
    Then I wanted to have the slider together with other controls in a formpanel.

    I get an error because there is no value (runtime error javascript: if(value.length<1||(value===me.emptyText&&me.value ContainsPlaceholder)){return errors;})

    When I add a Value I get another error:
    a parser error: Can not create object of type System.Object based on the string representation for the Value property. (translated)

    I am using Ext.net version 2.1, VS2010; IE10

    Hello!

    It seems to be a bug, we are investigating. For now please use overriding from the following example:

    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<!DOCTYPE html>
<html>
<head runat="server">
    <title>Custom GridPanel UI - Ext.NET Examples</title>
    <script>
        var linkClick = function (index) {
            alert("Company: " + App.Store1.getAt(index).get("company"));
        };

        var linkRenderer = function (value, meta, record, index) {
            return Ext.String.format("<a class='company-link' href='#' onclick='linkClick({1});'>{0}</a>", value, index);
        };
    </script>
</head>
<body>
    <ext:ResourceManager runat="server" ScriptMode="Debug" SourceFormatting="True" />
    <h1>
        Custom GridPanel UI</h1>
    <script>
        Ext.form.field.Base.override({
            getRawValue: function () {
                var me = this,
                    v = me.inputEl ? me.inputEl.getValue() : Ext.value(me.rawValue || me.value, '');
                me.rawValue = v;
                v = v == null && me.hiddenField ? me.hiddenField.getValue() : v;
                return v;
            }
        });
    </script>
    <ext:FormPanel ID="formPnlThemeConstruction" runat="server" Header="false">
        <Items>
            <ext:FieldContainer ID="FieldContainerTransparency" runat="server" FieldLabel="Transparantie"

                        MaxValue="100" Width="240">
                        <Listeners>
                            <Change Handler="#{txtSliderTransparency}.setValue(this.getValue());" />
                        </Listeners>
                    </ext:Slider>
                    <ext:TextField ID="txtSliderTransparency" runat="server" Text="0" Width="30">
                        <Listeners>
                            <AfterRender Handler="this.setValue(#{sliderTransparency}.getValue());" />
                            <Change Handler="#{sliderTransparency}.setValue(this.getValue());" />
                        </Listeners>

                </Items>
