panel

问题 I want to create my own custom control that is basically a TableLayoutPanel with 3 rows and 1 column. The top and bottom rows will contain labels (banners) and the middle row is where I will add other controls. The problem is that when I try to build other forms/controls from this control, the designer doesn't recognize the middle panel. How do I get it to? If I drag a textbox to the middle and set Dock=Fill, it will cover the entrie form/control. Also, is there any way to get the designer to

问题 tl;dr: I want to reuse the existing layouting logic of a pre-defined WPF panel for a custom WPF panel class. This question contains four different attempts to solve this, each with different downsides and thus a different point of failure. Also, a small test case can be found further down. The question is: How do I properly achieve this goal of defining my custom panel while internally reusing the layouting logic of another panel, without running into the problems described in my attempts to

问题 Ok, I know that FrameworkElement , which is a direct subclass of UIElement , has a Parent property, but Panels have children of type UIElement , not FrameworkElement (Children is of type UIElementCollection ) which seems it would mean you can add UIElement s directly to a Panel. That said, if you have a UIElement and want to see if it has a parent that's a panel, the only way I know how to test this is with the VisualTreeHelper , but that's the visual tree, not the logical tree. (At least we

问题 I have a few textboxes created dynamically , if i want to find the textboxes in the panels whats the best way to find it ? i search online and some said through FindName we might be able to find our control but for that i need to give every of my textbox a name and in WPF , a name must come with letters not int even if i put int.ToString it will screw up . but if i put letters , it will be difficult for me to locate them by letters , numbers will be okay since i can start from 00 and +1 all

问题 I'm doing a minimalist test app after encountering an issue with my real program, using WinForms. I put a small panel (child) inside a bigger panel (parent). The bigger panel has AutoScroll set to true. The child panel has the default Anchors set to Top and Left. The child panel is not docked. The behavior I want is for scrollbars to appear whenever the smaller panel's location is too offset, either top, bottom, left or right. The problem is that it only works when it's too far right, or too

问题 I need to reshape my data for panel data analysis. I searched the internet and only found out how to get the desired results by using Stata; however I am supposed to use R and Excel. My initial and final data(the desired result) looks very similar to the given in the first page of this example of reshaping data with Stata. http://spot.colorado.edu/~moonhawk/technical/C1912567120/E220703361/Media/reshape.pdf Is it attainable with R or just Excel? I tried using melt function from reshape2

问题 I want a panel to have some sort of dropshadow like the TabControl has, is this possible? 回答1: BorderStyle = Fixed3D take a look for the shadow in this example: http://www.onteorasoftware.com/downloads/panelwithshadow.zip Finally, the custom panel could be like (in VB): Imports System.Drawing.Drawing2D Public Class ShadowPanel Inherits Panel Declare Function GetWindowDC Lib "user32" Alias "GetWindowDC" (ByVal hwnd As IntPtr) _ As IntPtr Declare Function ReleaseDC Lib "user32" Alias "ReleaseDC

问题 I have seen this user interface in some screen shots of some RSS Readers. It is a multi-pane user interface. THere are three panels or "panes" to the window, in other words, the window is divided into three parts and the user is able to mouse over the division and click on the seperation bar and resize the section. How is this sort of GUI developed in C#? 回答1: In WinForms, this is done with a SplitContainer. The Orientation property can be used to get vertical or horizontal splits. You can

问题 I want to make Windows Forms controls readonly and IDisposable. Is this is a good thing or a bad thing and what do I have to watch out for when calling Dispose? I have a Tab (PageTab) that I extend and insert a Panel which has a listview and another Toolbar control into. These tabs then get inserted into a tab control (all native .NET Windows Forms controls). When the user closes one of these tabs I call the Dispose method (which follows the MSDN way of implementing IDisposable). Is it wise
