Backcolor of Disabled RadPanel

[Pavel Trnka]

Hi there,

very simple question, but i can't figure this out - where can I change the backcolor of RadPanel which is disabled? We are using the latest version of RadWinforms.

Thx so much

Hello Pavel Trnka,

In order to set the color of RadPanel when it is disabled, you need to set two properties:
1. The BackColor property to an appropriate value according to the Enabled state.
2. The UseDefaultDisabledPaint property should be set to false.

Please consider the following sample code snippet:

public Form1()
{
    InitializeComponent();

    this.radPanel1.RootElement.UseDefaultDisabledPaint = false;
    this.radPanel1.EnabledChanged += new EventHandler(radPanel1_EnabledChanged);
}

void radPanel1_EnabledChanged(object sender, EventArgs e)
{
    if (this.radPanel1.Enabled)
    {
        this.radPanel1.BackColor = Color.Transparent;
    }
    else
    {
        this.radPanel1.BackColor = Color.Red;
    }
}

Generally, it is not necessary to set the UseDefaultDisabledPaint to false in this case the colors of the FillPrimitive contained in the RadPanel are Transparent. However, if the FillPrimitive of the RadPanel has a color, this property should be set, otherwise, you will get gray colors for the this primitive.
