6 thoughts on “Setting the roll over color and selection color in a Flex DataGrid control

  1. tnx for the good work…
    i have a question..
    how do i cancel the selection color but keep the event..?
    i’m using custom styles for the rollover but i cant seem to get rid of the selection color..

    thanks in advanced :)

  2. What if I want to disable the header rollover? Is that possible while still maintaining sort functionality?

  3. I set “color” of each cell in datagrid based on condition. ie based on a condition the text in the cell is either red or blue.
    But for a highlighted row (either on selection or rollover) , the color of text is lost.
    I have noticed that this is the case when selectionMode=”singleRow”. When selectionMode=”singleCell”, and the cell is highlighted, the color of text is not lost. Please let me know if someone has solution to this problem.

    Thanks in advance
