Problem with theme

[Tooraj]

Hi,
When I change entire app's theme using associated class, My grid's header font doesn't appear with the font I set for prevous theme. this happens for Win7 and Desert themes. How to solve this? please tell me.
How can I get rid of Telerik theme's header display glitch (shows header gray color and after mouse hover backs to original color(green))?
Thank you again, Tooraj Azizi.

Hi Tooraj,

Thank you for writing.

The Telerik theme is a theme created with our old theming mechanism and we are no longer providing fixes for it. We are planing on remaking it using our new theming mechanism, but at the moment I cannot give you a specific time frame for this. 

For the moment you can use the ViewCellFormatting event of the RadGridView to resolve both your issues. Consider the following code snippet:

void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    if (e.CellElement is GridHeaderCellElement)
    {
        e.CellElement.Font = new Font(FontFamily.GenericMonospace, 12);

        if (ThemeResolutionService.ApplicationThemeName == "Telerik")
        {
            e.CellElement.BackColor = Color.FromArgb(246, 254, 213);
            e.CellElement.BackColor2 = Color.FromArgb(232, 253, 154);
            e.CellElement.BackColor3 = Color.FromArgb(218, 251, 94);
            e.CellElement.BackColor4 = Color.FromArgb(218, 251, 94);
            e.CellElement.GradientPercentage = 0.49f;
            e.CellElement.GradientPercentage2 = 0.50f;
            e.CellElement.NumberOfColors = 4;
            e.CellElement.DrawFill = true;
        }
        else
        {
            e.CellElement.ResetValue(GridHeaderCellElement.BackColorProperty);
            e.CellElement.ResetValue(GridHeaderCellElement.GradientStyleProperty);
            e.CellElement.ResetValue(GridHeaderCellElement.DrawFillProperty);
        }
    }
}

I hope this will help. If you have further questions, I would be glad to help.

All the best,
