问题 I have a TabControl which contains a StackPanel with many Expander. In each Expander I placed an UserControl. So, I have a clear view. The UserControl contains a DataGrid. Now, the problem is, that the height from the DataGrid is not set. If the DataGrid is lager than the window-size no Scrollbar is shown. <TabControl SelectionChanged="Selector_OnSelectionChanged" Height="Auto"> <TabItem Header="DoSmth"> </TabItem> <TabItem Header="Misc" Height="Auto"> <StackPanel Height="Auto"> <Expander

问题 I want to have a graphical part in my UserControl which will display Lines based on a collection (and update coords during runtime and also add/remove lines during runtime based on the collection). Lets assume I have a class called Class1: public class Class1 : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; public void OnPropertyChanged(PropertyChangedEventArgs e) { if (PropertyChanged != null) PropertyChanged(this, e); } private int _x1 = 0; public int X1

问题 I have a UserControl for an application and with a textbox. When pressing enter in this textbox a button should be activated (basically pressing 'Ok' via pressing Enter instead of clicking the button manually with the mouse). So I added a KeyDown event to my textbox and implemented the following code: private void txtSearchID_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Enter && !txtSearchID.Text.Equals(string.Empty)) { button_Click(null, null); } } But when I wanted to test

问题 I am looking to handle incoming telnet text that has ANSI escape codes. For the bounty I am looking for a full implementation where I can just append text to the end of a buffer. The control should be scrollable, yet still be able to handle appending text, cursor positioning, etc.. while the user is scrolled out of view. For example, "\e[0;32mHello \e[0;37mWorld" Would display a green "Hello" and a white "World" As this would need to handle cursor positioning, setting a default 80 characters

问题 I am creating a user interface and I am trying to figure out the best way to organize all of my custom controls. I already know that I can do the following: 1) If I want to have a property visible for design-time manipulation via the Properties window, I use the following... [Browsable(true)] [Description("Text for Display"), Category("Custom Properties")] public string DisplayText { get { return textDisplay.DisplayText; } set { textDisplay.DisplayText = value; } } 2) If I want to hide the

问题 I know that there is the possibility of Matlab of pausing a Matlab function or script by using input() thus when I have a for-loop and want to pause it every iteration: for i = 1:N reply = input(sprintf('Pausing in iteration %d! Continue with Enter!', i), 's'); % Calculations end but how to get the following working: Usually it runs without pausing (as if the input() wouldn't be there) but when the user does something (perhaps press a key, a button, or something similar in matlab), the script

问题 in my UWP app I was thinking to extract my data template into a seperate user control , i.e: <DataTemplate><local:CustomTemplate/></DataTemplate> and the user control ( customtemplate ) will have that stackpanel or grid which was previously in my DataTemplate directly, along with its bindings, I already know how to achieve this. My Question is that by extracting out the data template in a user control, would this cause any performance hit? I read somewhere that while doing this each

问题 I am creating Web User Controls via code (my C# code write-out markup, code-behind and designer files to disk on a callback). The controls are created all fine. I can add them to my web-project and put them on a page. When I try to load the control using LoadControl(path) it says: Unable to load type 'MyNameSpace.UseControlClass' which is because control is not yet compiled. But my requirement is to load controls dynamically without recompiling the solution. How can I compile the user control
