The "WPF paging DataGrid" describes how to implement paging functionality, which is described in this article if you implement the right-click menu. See figure below:Click on the menu item age, hide the Age column, and then click the display, and implement the Move column, synchronized display. To implement a feature you need to add a right-click menu to the column when loaded events. public class Pagingdat

In WPF, if a template column is used in a DataGrid, the list content appears cluttered when you drag the scroll bar. The solution is to assign values to UpdateSourceTrigger when binding. The background code is as follows: public class Student {public string Name {get; set;} public string Age {get; set;} Public list The above is the entire content of this article, I hope to h

To notify controls in a timely manner when data in the data source changes, you need to implement the inotifypropertychanged interface in a class.

(verified available) 2. If 'get' is used, add a random number after the URL request. 3. Disable browser cache Analy
