GroupBar header gradient colours

[Vijaya Kumar Reddy]

Hi,

I am using a gradient panel control in one of my usercontrols. Along with my user control I have the group bar control with StackedMode=true and VisualStyle to Office2003. I tried to simulate the same gradient colours as in the GroupBar control''s header in my gradient panel. But as we change the Windows XP theme the colours will not match as I am not using Standard System colours.

Please let me know what are the System Colours you used to paint the Header portion of the GroupBar Control, so that I will apply the same for my Gradient Panel Control. Or suggest me a similer control that can be used as a header with the same colour pattern.

Thanks for the help in advance.

Regards
Vijay

Hi Vijay,

You can apply same color for both gradient panel and groupbar header, what colors you used in gradient panel , you just given that colors to the Groupbar header.

Here is the code snippet:
Office2003Colors.GroupBarHeaderColorDark = Color.LightSteelBlue;
Office2003Colors.GroupBarHeaderColorLight = Color.Black;

Please refer the attachments and let me know if I have missed anything.

Thank you,
S.Gopal.

Hi Vijay,

The following are the colors used in GroupBar header for different XPThemes. You can use the same code in your application after InitializeComponent.

[C#]

if (XPThemes.IsDefaultBlueThemeOn)
this.gradientPanel1.BackgroundColor = new BrushInfo(GradientStyle.Vertical, Color.FromArgb(89, 135, 214), Color.FromArgb(3, 56, 147));

else if(XPThemes.IsSilverThemeOn)
this.gradientPanel1.BackgroundColor = new BrushInfo(GradientStyle.Vertical, Color.FromArgb(179, 178, 200), Color.FromArgb(124, 124, 148));

else if(XPThemes.IsOliveGreenThemeOn)
this.gradientPanel1.BackgroundColor = new BrushInfo(GradientStyle.Vertical, Color.FromArgb(176, 194, 140), Color.FromArgb(96, 128, 88));

Please let me know if this helps.

Thanks,

Hi Vijay,

Please add the previous code in the Form_Paint event instead of Form_Load event.

Hi Mano,

It is still the same even after adding that code in the form_paint event.

Please send me your code if it is different from me which is working good in your machine.

Hi Vijay,

Sorry for the delay in getting back to you. I did not make any major changes to the sample. I just moved the code from form_load to form_paint event and it works fine in my machine.

I checked this issue in VS 2003 using v.3.2.1.0. However I have attached the sample. Please check it and let me know.

Hi Mano,

While running the app I am getting the following exception..

An unhandled exception of type ''System.InvalidCastException'' occurred in WindowsApplication3.exe

Additional information: Specified cast is not valid.

It stops at the line 19 in Form1.cs. ....

((System.ComponentModel.ISupportInitialize)(this.gradientPanel1)).BeginInit();



Please look into this and let me know.

Thanks and regards
Vijay

Hi Mano,

The line mo 19 in my previous post is incorrect. The correct Line no is 67.
