I would like to invisible the expansion indicator, is any built-in properties there?
??? you mean the left right arrows? and are you saying you don't want to allow them to collapse it?
Yes , I should not allow them the panel to expand when ever it is double clicked...
Setting the CollapsedDirection property off the SplitterPane to None should cause the expand/collapse indicator not to show.
Thank you for reply i will check it out and let you know...
