问题 I have two separate ItemsControl s that appear side by side. The ItemsControl s bind to the same ItemsSource , but they display the data differently. Each item displayed on the left will most likely be smaller than the same item on the right. This causes a problem because the rows will not line up, so I need the item on the left to bind to the item on the right. ItemsControl ItemsControl |Item 1 |Item 1 |Item 2 |Item 2 |Item 3 | |Item 4 |Item 3 As you can see, Item 2 on the right is larger,

What to do to mantain the rectangle and textbox of same size? 回答1: The correct binding

问题 I have a TextBlock with a Border around it that's inside of a Canvas that I'm using to animate it as part of a custom control. The block slides in from the bottom of the screen over the top of the image. I'm trying to use the ActualHeight of the TextBlock to determine how far to move it onto the page, but when there is so much text that it wraps to two lines, the ActualHeight returns the same size as though there was a single line. TextBlock: <DataTemplate DataType="{x:Type contentTypes

问题 This question already has answers here : WPF DataGrid : CanContentScroll property causing odd behavior (2 answers) Closed 6 years ago . Both are quite general terms but I'm curious to know when these height will be different apart from the case we're using Virtualization? One more question: I read on MSDN: If CanContentScroll is true, the values of the ExtentHeight, ScrollableHeight, ViewportHeight, and VerticalOffset properties are number of items. If CanContentScroll is false, the values of
