我在WP7中有一个webscrollview,它最初没有焦点(内容是hittestVisible,因此取消了scrollviewers的hittestvisibility).当我将内容的可见性设置为false时,我可以滚动滚动浏览器,但是仅在解除手指之后再次将其重新放回.我真的很喜欢重点转移,之后重新应用焦点,以便我可以在滚动视图获得焦点后滑动,不要等待下一个操作开始事件触发.
这是我的代码：

</Grid>
在C#中：
protected override void TouchFrameDelta( object sender,TouchFrameEventArgs e )
{
if ( UserManipulating == ManipulationState.ManipulationStopped )
{
UserManipulating = ManipulationState.ManipulationStarted;
ManipulationStartingPoint = e.GetPrimaryTouchPoint( null ).Position;
}
//if we are already manipulating the scrollviewer,we do nothing
if ( UserManipulating != ManipulationState.ManipulationStarted )
{
return;
}
TouchPoint touchPoint = e.GetPrimaryTouchPoint( null );
float differenceStart = ( float )( touchPoint.Position.X - ManipulationStartingPoint.X );
if ( Math.Abs( differenceStart ) >= 25 )
{
if ( BrowserListIsHitTestVisible )
{
BrowserListIsHitTestVisible = false;
MiddleContentControl.Focus( );
MiddleContentControl.UpdateLayout( );
return;
}
float differenceDelta = ( float ) ( touchPoint.Position.X - ManipulationDeltaPoint.X );
if ( touchPoint.Action == TouchAction.Up )
{
UserManipulating = ManipulationState.ManipilatingScrollViewCompleted;
OnManipulationCompleted( differenceDelta );
}
}
ManipulationDeltaPoint = touchPoint.Position;
}
TouchFrameDelta是Touch.FrameReported事件.
有没有人有一个想法为什么这不工作,如何解决？
提前致谢
