Formatting Scheduler Resource Header Cell Element

[Allen]

Using the Visual Style Builder to set theme colors I can see how to modify the Scheduler Header Cell Element, but where is the Resource Header Cell Element modified?  I would to set this in the theme because my application allows loading of predefined themes; therefore I prefer not to use the SchedulerCell_Format event.  Thank you for any guidance you can provide.

Hello Allen,

Thank you for writing. 

SchedulerResourceHeaderCellElement's color depends on the resource's color that is applied. It is not possible to customize the SchedulerResourceHeaderCellElement in Visual Style Builder. Feel free to use the CellFormatting event and apply the desired style to the header cells. Here is a sample code snippet:

Font f = new Font("Arial", 14f, FontStyle.Italic);

private void radScheduler1_CellFormatting(object sender, SchedulerCellEventArgs e)
{
    SchedulerResourceHeaderCellElement headerCell = e.CellElement as SchedulerResourceHeaderCellElement;
    if (headerCell != null)
    {
        headerCell.Font = f;
    }
    else
    {
        e.CellElement.ResetValue(VisualElement.FontProperty, ValueResetFlags.Local);
    }
}

I hope this information helps. Should you have further questions I would be glad to help.

Thanks.  That helped get me going down the right road.  Is there a way to turn off the resource color from being applied to the Scheduler Cell elements?  I understand how to change the header cell format, but by default it looks like a percentage of the resource color is being "overlayed" on the scheduler cell colors.

Hello Allen, 

Thank you for writing back. 

In order to customize the cell's back color, you can set the CellElement.BackColor property. In addition, it is necessary to set the Opacity property to 1 to obtain the desired color.

private void radScheduler1_CellFormatting(object sender, SchedulerCellEventArgs e)
{
    e.CellElement.Opacity = 1;
    SchedulerResourceHeaderCellElement headerCell = e.CellElement as SchedulerResourceHeaderCellElement;
    if (headerCell != null)
    {
        headerCell.BackColor = Color.Pink;
        headerCell.GradientStyle = GradientStyles.Solid;
    }
    else if (e.CellElement is SchedulerCellElement && e.CellElement.Date.Year > 1999 && e.CellElement.Text == string.Empty)
    {
        e.CellElement.BackColor = Color.Yellow;
        e.CellElement.GradientStyle = GradientStyles.Solid;
    }
    else
    {
        e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.OpacityProperty, ValueResetFlags.Local);
    }
}

I hope this information helps. If you have any additional questions, please let me know.
