问题 Is there a reason why the text content of a WPF button is appearing with unwanted space above the text? I have a button in a StackPanel. This button is a simple close button so I want it to appear as a square button with an "x" centred in it. I have set my padding to zero and set both the HorizontalContentAlign and VerticalContentAlign to Center but the "x" still appears at the bottom of the button (or even truncated should I have my FontSize too big relative to my Height). It's as if there

问题 I am searching for Volume Slider that looks and behave just like VLC's slider. I found the following post about how to style the slider: Volume Slider CustomControl but I also want the same behavior... What is the difference between the behaviors: When you click on the slider [at the WPF] and move the mouse on the slider area (while mouse button still being hold) it should move the slider also to the position of the mouse on the slider. I couldn't find how to do it.. maybe I should use

问题 I want to style the indeterminate state of a WPF checkbox. We have a treeview control with checkboxes, and we want the indeterminate state to represent that some descendants are checked and some are unchecked. The solution I'm seeing everywhere is to override the default control template for a checkbox and do what I need to do.

问题 So anyone out there knows of sample code or control that perfectly emulates the Windows 8 Start Menu Tile Layout Engine?

问题 Is it possible to hide a part of a WPF control? .NET 4 has a DatePicker which renders 4 parts, according to MSDN. Is it possible to hide (in my case) the TextBox part (probably named PART_TextBox)? I have seen examples of styling the DatePicker completely, and it involves alot of XAML, when all I want to do is hide one part of the control. 回答1: Well, I have a solution for your case :) class MyDateTimePicker : DatePicker { public override void OnApplyTemplate() { base.OnApplyTemplate(); var
