I have a pageframe with 5 pages. Each page have 2 grids. I dropped 2 GridHighLighter control class in each page to handle each grid. The only problem is in the 5th page wherein it gives me an error: "Expression is invalid! Use valid expression for DynamicFontBold property", the first time I click it. But succeeding clicks works and behaves normal. What seems to be problem here?

Also Nick, why is it that the default background of the highlighted header is Pink? Can't you make it Dark Blue. I can change it though but it's uncommon to use pink as background color unless the user is halfhalf :)
