问题描述
如何使枢轴/选项卡标题具有相同的宽度并拉伸枢轴标题的整个宽度而不超出屏幕(特别是对于移动设备)?我还没有找到如何做到这一点的例子.
这是我想要实现的目标:
解决方案
如何使枢轴/选项卡标题使每个单独的选项卡具有相同的宽度并拉伸整个宽度
这可能无法仅通过设置
How can I make the pivot/tabs header have each individual tab be the same width and stretch the full width of the pivot header and not extend off the screen (particularly for mobile)? I have yet to find an example of how to do this.
Here's what I'm trying to achieve:

This might not be able to implemented by just setting the style of pivot. But this can be easily implemented by ViewTreeHelper class. We can try to calculate the width of each header item by actualwidth of the pivot header and the total header items count. And set the width manually, then the header items will stretch the full width.
Code example like follows:
<Pivot x:Name="CustomPivot">
<Pivot.Resources>
<Style TargetType="PivotHeaderItem">
<Setter Property="FontSize" Value="{ThemeResource PivotHeaderItemFontSize}" />
<Setter Property="FontFamily" Value="{ThemeResource PivotHeaderItemFontFamily}" />

{
if (depObj != null)
{
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
{
DependencyObject child = VisualTreeHelper.GetChild(depObj, i);
if (child != null && child is T)
{
yield return (T)child;
}
foreach (T childOfChild in FindVisualChildren<T>(child))
{
yield return childOfChild;
}
}
}
}
private void Page_Loaded(object sender, RoutedEventArgs e)
{
IEnumerable<PivotHeaderPanel> headerpanel = FindVisualChildren<PivotHeaderPanel>(CustomPivot);
double totalwidth = headerpanel.ElementAt<PivotHeaderPanel>(0).ActualWidth;
IEnumerable<PivotHeaderItem> items = FindVisualChildren<PivotHeaderItem>(CustomPivot);
int headitemcount = items.Count();
for (int i = 0; i < headitemcount; i++)
{
items.ElementAt<PivotHeaderItem>(i).Width = totalwidth / headitemcount;
}
}
