Xam Data Grid Focus Header Color Change
posted

Hi Team,

I have got the requirement to display header color by default grey text (on page load).When any part of the Xam Data Grid is clicked the header of the grid needs to be turned to blue colour.Same case applies when the user clicks on some other region other than the grid the header colour changes to grey again.

Can you please provide your valuable time in making me achieve this.Thanks in advance for all your support.

Below mentioned is the style for Xam Data Grid .

    Hello Sridhar,

    I'm not sure you need to mess with the whole LabelPresenter style just to achieve this functionality.  It could be as simple as checking the XamDataGrid's IsKeyboardFocusWithin property and then applying a basic style to the XamDataGrid.FieldSettings.LabelPresenterStyle that sets the background color to the desired result.

    Or you could have a DataTrigger in the Style.Trigger on LabelPresenter that uses a RelativeSource binding up to the XamDataGrid and binds to it's IsKeyboardFocusWithin property and uses that to determine what the color should be.

    If you need to keep your above style, just add another DataTrigger to it that binds up to the IsKeyboardFocusWithin property and then changes the colors accordingly.  90% of the time when you click away from the control onto another one that steals focus, it will also steal keyboard focus and that property will update.  The times where it wouldn't update is if the control itself went out of its way to keep keyboard focus and the XamDataGrid doesn't do this.
