Programatic Styling For Specific Cells?

[Steve]

I have a Silverlight RadGridView that represents six months of the year.  Each row of data in the grid is stored as a record in an SQL table.

I want to allow users to attach a Note to a cell in the grid by right-clicking a cell and using a context menu to New | Edit | Delete a Note.  Each cell in the grid could have a Note associated with it…but most likely only a few Notes will get attached to the grid.

I need to be able to visually identify cells that have a Note associated with them.  I was thinking of applying  a background to cells that have notes (similar to Microsoft Excel’s use of a red tag in the upper right corner of the cell).  The Notes are stored in a separate SQL table and are tagged with the date that corresponds to the cell.

I have been able to set the background for specific columns:

 

                        //Sets the whole column

                        participantExerciseDetailsRadGridView.Columns[col].Background = new SolidColorBrush(Colors.Orange);

 

How do I go about setting the background color of specific cells (programmatically)?  I am already using a Conditional Style Selector to identify cells in Columns 29, 30, & 31 that are not valid dates and setting the ‘IsEnabled’ property to true | false.  I thought about creating another conditional style selector, but it appears that I cannot have multiple conditional style selectors on the same column.

Hi Steve Dentel,

Yes, you are right. A column can have only one StyleSelector set, but the StyleSelector itself may operate with multiple styles and apply them regarding multiple conditions. So it is possible to have a StyleSelector that applies a style that modifies cells' background when a condition is fulfilled and another style, when another condition is fulfilled. For more extensive information, please refer to this article.

Thanks for the article on style selectors.  Do you have a VS2010 solution that you can provide that will help me understand this?

From my first post, I asked if there was a way to select a cell and style it.  Is it possible to do this without using style selectors as I was able to do for the entire row?

Thanks,

Steve

Hi Steve Dentel,

I have prepared a sample project for you that utilizes a StyleSelector with multiple conditions. Please, refer to it and inform us if this approach meets your requirements.
