I need to create an adorner that covers multiple cells of a xamDataGrid record.
Where is the best place to decorate records with adorners? I would like to set up the adorners once for each record. Currently, I'm adding the adorners in the RecordsInViewChanged event handler. It sort of works - the adorners do appear - but this event fires at the wrong time for me so my code has logic to avoid adding duplicate adorners to the same record.
I think if I add the adorners at the right time in the lifecycle of the xamDataGrid, then this problem might go away: The adorners are transparent and it is clear that they are being drawn multiple times in the first 3 or last 3 records on the grid when the grid is scrolled up or down.
I attached my current solution. It is Visual Studio 2010 with NetAdvantage 10.3.
Hello,
I wanted to follow up, please let me now if you have any further question.
Thank you,
Sam
Have you considered using the default style locally so you could style it anyway you wanted? the default generic style file is located here:
C:\Program Files\Infragistics\NetAdvantage 2010.3\WPF\DefaultStyles\DataPresenter
Fixed the problem where extra adorners were being rendered. They weren't duplicates; they were adorners for rows that were scrolled out of view (I think the xamDataGrid is mis-behaving). Adding a check to see if the AdornedElement is visible in Adorner.OnRender fixed the problem:
if (!this.AdornedElement.IsVisible) return;
I'm still seeking advice on the best way to create DataRecord adorners.
