How To Dynamically Set Font On GridViewHeaderCell?

[Albert]

I have a RadGridView populated with data. I have some input controls that allow the user to change the font of the text in the header rows. I tried the following in the code-behind, but it did not work. What is the correct way to do this?

System.Windows.Style headerStyle = new Style();
headerStyle.BasedOn = reportGrid.Columns[0].HeaderCellStyle;
headerStyle.TargetType = typeof(GridViewHeaderCell);
headerStyle.Setters.Add(new Setter(GridViewHeaderCell.FontSizeProperty, 25));
reportGrid.Columns[0].HeaderCellStyle = headerStyle;

Kind Regards,
Albert

Hello 
I need to do the same. I have done it with an attached property which adds a contextmenu to this grid. 
With this it is possible to change the font of the header over this context menu. 
A font picker I do not have at the moment but the changing works if I do it in code: 

_localRadGridTableStyle = new Style(typeof(GridViewHeaderCell));       
_localRadGridHeaderStyle.Setters.Add(new Setter        
   {             
       Property = GridViewHeaderCell.FontFamilyProperty,      
       Value = _headerFontInfo.Family        
   });
.... some other setters...
this.grid.Resources.Add(typeof(GridViewHeaderCell), _localRadGridTableStyle);    

It works, but I don't know if this is a good solution. I'm searching for a solution to save this new 
style at closing of this grid and load saved style again next time...
Which FontPicker do you take?

Hello,

You can set the Style like so:

headerStyle.TargetType = typeof(GridViewHeaderCell);
double value = 25;
headerStyle.Setters.Add(new Setter(GridViewHeaderCell.FontSizeProperty, value));
clubsGrid.Columns["Name"].HeaderCellStyle = headerStyle;

I hope this helps.
