在C#中的xps文档中设置PageHight自动
在C#中的xps文档中设置PageHight自动
提问于 2013-05-24 18:20:01
我们可以在C#的xps文件中设置高度自动吗？如果我设置了高度，并且包含的内容超过了这个值，那么它会给我一个空白页面。
我的模板代码如下

萨钦，这是我的代码。我用文件中的内容动态加载堆栈面板，刷新它们的绑定值，并计算它们的大小。之后，我决定是在该页面上添加元素，还是转到其他页面。我的代码示例如下：
public bool ApplyVisualBlock(FrameworkElement visulaBlock)
{
//update binding values
UpdateAllBindingTargets(visulaBlock);
_contentContainer.Children.Add(visulaBlock);
//calculate size
visulaBlock.Measure(new Size(ContentWidth, ContentHeight));
double visualBlockHeight = Math.Ceiling(visulaBlock.DesiredSize.Height);
if ((visualBlockHeight + _currentContentHeight) > ContentHeight)
{
//if current cocntent height more than page height go to other page
_contentContainer.Children.Remove(visulaBlock);
return false;
}
_currentContentHeight = _currentContentHeight + visualBlockHeight;
return true;
}
public void UpdateAllBindingTargets( DependencyObject obj)
{
FrameworkElement visualBlock = obj as FrameworkElement;
if (visualBlock==null)
return;
if (visualBlock.DataContext==null)
return;
Object objDataContext = visualBlock.DataContext;
IEnumerable<KeyValuePair<DependencyProperty, BindingExpression>> allElementBinding = GetAllBindings(obj);
foreach (KeyValuePair<DependencyProperty, BindingExpression> bindingInfo in allElementBinding)
{
BindingOperations.ClearBinding(obj, bindingInfo.Key);
Binding myBinding = new Binding(bindingInfo.Value.ParentBinding.Path.Path);
myBinding.Source = objDataContext;
visualBlock.SetBinding(bindingInfo.Key, myBinding);
BindingOperations.GetBindingExpression(visualBlock, bindingInfo.Key).UpdateTarget();
}
}
public IEnumerable<KeyValuePair<DependencyProperty, BindingExpression>> GetAllBindings( DependencyObject obj)
{
var stack = new Stack<DependencyObject>();
stack.Push(obj);
while (stack.Count > 0)
{
var cur = stack.Pop();
var lve = cur.GetLocalValueEnumerator();
while (lve.MoveNext())
if (BindingOperations.IsDataBound(cur, lve.Current.Property))
{
KeyValuePair<DependencyProperty,BindingExpression> result=new KeyValuePair<DependencyProperty, BindingExpression>(lve.Current.Property,lve.Current.Value as BindingExpression);
yield return result;
}
int count = VisualTreeHelper.GetChildrenCount(cur);
for (int i = 0; i < count; ++i)
{
var child = VisualTreeHelper.GetChild(cur, i);
if (child is FrameworkElement)
stack.Push(child);
}
}
