c# - WPF ignores d:IsHidden="True" in run mode (OK in design mode) -


why left image hidden in design mode , not hidden in runtime? looks wpf ignores attribute "ishidden". new empty solution, no single line of code - blend.

left design mode - right in run mode

here code

<window     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:ignorable="d" x:class="wpfapplication222.mainwindow"     title="mainwindow" height="350" width="525"> <grid>     <image horizontalalignment="left" height="157.093" margin="98.316,88.148,0,0" verticalalignment="top" width="95" source="pack://siteoforigin:,,,/img0.jpg" rendertransformorigin="0.5,0.5" d:ishidden="true">         <image.rendertransform>             <transformgroup>                 <scaletransform/>                 <skewtransform/>                 <rotatetransform angle="-37.445"/>                 <translatetransform/>             </transformgroup>         </image.rendertransform>     </image>     <image horizontalalignment="left" height="122" margin="350,92,0,0" verticalalignment="top" width="106" rendertransformorigin="0.5,0.5" source="pack://siteoforigin:,,,/img14.jpg">         <image.rendertransform>             <transformgroup>                 <scaletransform/>                 <skewtransform/>                 <rotatetransform angle="13.144"/>                 <translatetransform/>             </transformgroup>         </image.rendertransform>     </image> </grid>

at top of xaml, you'll see following:

mc:ignorable="d"

this says "ignore prefixed d: @ runtime."

you can either remove line (not recommended), or use visibility property instead. not ignored.
