Silverlight DependencyProperty.SetCurrentValue Equivalent

由 谁都会走 提交于 2019-12-24 03:19:30
问题 I'm looking for a SL4 equivalent to .NET 4's SetCurrentValue API, which would appear to be exactly what I need for my scenario. In short, I'm writing an attached behavior that updates the value of a given property at appropriate times. However, I don't want it to overwrite any bindings that are set on that dependency property. I merely want to push that value to the property (and therefore have any bindings refresh based on that value). From what I can tell, there's no easy way to do this yet

Android - ViewPager Adapter, set primary item before adapter is instantiated

问题 I know i can do viewPager.setCurrentItem(position) to set my view pager at the desired position. My question is if and how i can do this before the adapter is instantiated. Meaning that if I do pagerAdapter = new ViewPagerAdapter(arg1,arg2....); viewPager.setAdapter(pagerAdapter); viewPager.setCurrentItem(position); item 0 is first build and after that the item at the desired position is also build. Which takes double the time...In my adapter each item needs quite a lot of work to be build,

The reason why I am asking this is because I was recommended by @Greg D (from this question ) to use SetCurrentValue() instead, but a look at the docs and didn't see whats the difference. Or whats does "without changing its value source" mean? SetValue() Sets the local value of a dependency property, specified by its dependency property identifier. SetCurrentValue() Sets the value of a dependency property without changing its value source. Kent Boogaart The MSDN link you provided says it quite well: This method is used by a component that programmatically sets the value of one of its own
