It is mentioned that DataGrid is frequently used in both web pages and application development. With it, we can flexibly display various data between rows and columns. This article describes the functions of DataGrid in WPF 4 in detail.Custom Columns By default, after the ItemSource attribute is set for the DataGrid Control, the DataGrid automatically generates columns based on the data type. The following

HbitmapCreatebitmapsourcefromhicon ()//Get ImageSource from HiconCreatebitmapsourcefrommemorysection ()//Get ImageSource from HmemThe following are additional examples of code snippets in the following work:Captureimagetool capture = new Captureimagetool ();if (capture. ShowDialog () = = System.Windows.Forms.DialogResult.OK){System.Drawing.Image Image = Capture. Image; Get drawing imageBitmap bmp = new Bitmap (image); Get bitmapSystem.Windows.Media.Imaging.BitmapSource Bmpresource =System.Windo

The columns used in the DataGrid are automatically generated, but as you know, WPF's DataGrid will be in the last column, and the usual solution is to set the Width= "*" On the last column, so that the last column has no more.But ah, background generation can write this width= "*", online information is difficult to find, so it is not nonsense, directly on the codeDatagridlength length=New datagridlength (1, Datagridlengthunittype.star); = length;This means that width= "*", of co

In the previous WPF 4 DataGrid control (custom style article), we mastered the DataGrid list header, row header, row, cell-related custom style method, and we continue to make some advanced settings for the custom style.

UserControl, customize the control.A question has just come to mind here. When should you define a control with UserControl. When should you rewrite the template and style of the control to achieve the new effect.Quote someone's words: http://www.cnblogs.com/denghejun/p/3671061.htmlMy understanding:UserControl should be a function with a control with a behavior.

When we create Basewindow in WPF or want to inherit a custom UserControl, we often encounter errors such as "The root of a XAML file cannot occur after inheritance." The reason is that inheriting a class will flush out all the contents of the base class if the contents of the form are redefined:Workaround: 1. Base class is set to inherit window or UserControl generic class file, do not create a file with XAML. or use custom controls to create their o

When we want to print the contents of a control, such as what is in a grid, you can use the Printvisual () method of the PrintDialog class in WPF to implementThe interface is as follows:The XAML code is as follows1 Grid>2 grid.columndefinitions>3 ColumnDefinition/>4 ColumnDefinitionWidth= "+"/>5 grid.columndefinitions>6 GridGrid.column= "0">7 8 Gr

The ProgressBar control is very useful. Under what circumstances would it be useful? How do I use it? With these two questions, let's explore the next.If the program takes a long time to run, the user does not know the situation, that the program has been "stuck", no response, this time to use the progress bar, it actively tell the user's implementation, then the user knows how long to wait.The above usage scenario, very well understood, then, how to

In general, it is to define a controltemplate without targettype, and then add adornedelementplaceholder to the template.

NPOI exports the display data of the WPF DataGrid Control, npoiwpf Recently, when I was working on a project, I needed to export the data displayed in the DataGrid. I encountered a lot of pitfalls in the middle. I would like to record them here for future reference. I also hope to provide some help to users. The data displayed in the export DataGrid is not the ItemsSource of the export DataGrid. There is a

Although WPF dynamically loads controls from the background, it is not often used, but there are not many materials on the Internet. Today, I made such a small thing and recorded it as follows: First, we add a Dynamic Loading Function loaded = "window_loaded" in the file header of The XAML file" And name the window form, X: Name = "win_mainx" The definition of the entire header is as follows: Xmlns = "http://schemas.microsoft.com/winfx/2006/
