    [CLOSED] Label properties ForeColor and BackColor on codebehind

    Hello while migrating I have just noticed that ForeColor and BackColor does not seem to work on codebehind.
    Here is an example which shows it. In the breaking changes there is no mention about it. Is a bug or I need to set the colors in a different way?

    Here is an example code, nor the background color nor the foreground color are displayed

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

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {

        // Build Window to hold everything
        Window win = new Window();
        win.ID = "Window1";
        win.Layout = LayoutType.Form.ToString();
        win.Title = "Test Controls";
        win.Icon = Icon.Application;
        win.Width = Unit.Pixel(600);
        win.Height = Unit.Pixel(350);
        win.Border = false;
        win.Collapsible = true;
        win.Plain = true;

        Ext.Net.Label webLabel=new Ext.Net.Label();
        webLabel.Text="This label should be red with green background";
        
        //foreground color should be red and backgroud green
        
        webLabel.ForeColor=System.Drawing.Color.Red;
        webLabel.BackColor=System.Drawing.Color.Green;
        
        win.Items.Add(webLabel);
        

        // Add Window to Form
        this.PlaceHolder1.Controls.Add(win);
    }
</script>

    <h1>Test</h1>
    
    <ext:Button 
        ID="Button1" 
        runat="server" 
        Text="Show Window" 
        Icon="Application">
        <Listeners>
            <Click Handler="#{Window1}.show();" />
        </Listeners>    
    </ext:Button>
    
    <asp:PlaceHolder ID="PlaceHolder1" runat="server" />

    SOLVED.

    These properties have no effect I can change the colors using the StyleSpec property.

    This other example works.

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

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {

        // Build Window to hold everything
        Window win = new Window();
        win.ID = "Window1";
        win.Layout = LayoutType.Form.ToString();
        win.Title = "Test Controls";
        win.Icon = Icon.Application;
        win.Width = Unit.Pixel(600);
        win.Height = Unit.Pixel(350);
        win.Border = false;
        win.Collapsible = true;
        win.Plain = true;

        Ext.Net.Label webLabel=new Ext.Net.Label();
         webLabel.Text="This label should be red with green background";
        
        //foreground color should be red and backgroud green
        string textstyle=string.Format(System.Globalization.CultureInfo.InvariantCulture,
                                          "color:rgb({0},{1},{2});",
                                          System.Drawing.Color.Red.R,
                                          System.Drawing.Color.Red.G,
                                          System.Drawing.Color.Red.B);
          
        textstyle+=string.Format(System.Globalization.CultureInfo.InvariantCulture,
                                          "background-color:rgb({0},{1},{2});",
                                          System.Drawing.Color.Green.R,
                                          System.Drawing.Color.Green.G,
                                          System.Drawing.Color.Green.B);
                                          
        webLabel.StyleSpec=textstyle;
        
        win.Items.Add(webLabel);
        

        // Add Window to Form
        this.PlaceHolder1.Controls.Add(win);
    }
</script>

    Hi @jcanton,

    Yes, those properties are not supported.

    I'll add a little additional information, those properties are inherited from the ASP.NET WebControl base class, and there is no way to hide/remove them from Intellisense. We just ignore them.
