This article mainly introduces ".NET 2.0 data binding problem Analysis". In daily operation, I believe that many people have doubts about .NET 2.0 data binding problem analysis. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts of ".NET 2.0 data binding problem Analysis"! Next, please follow the editor to study!
The problem is described as follows:
I have a Class like this:
Public class BindTest {private int number = 5 private int anotherNumber = 10 public int AnotherNumber public int Number {get {return number;} set {number = value;}} public int AnotherNumber {get {return anotherNumber;} set {anotherNumber = value;}
There are two controls on the form, one is textBox1, which binds the Number property, and the other is textBox2, which binds the AnotherNumber property. Since I need the confirm and cancel buttons, I changed the binding behavior of the two controls to Never in the advanced binding, that is, I did not update its value.
As explained in MSDN, the data can be updated using Binding's WriteValue () method. I can write this in my program: textBox1.DataBinding [0] .WriteValue ()
TextBox2 does something similar.
Later, as soon as it was run, the problem came out, only the value of textBox1 could be updated, while the value of textBox2 was restored!
After a search, I went back to the discussion at the beginning, and someone said:
In short, an attempt is made to manipulate the write and read behavior of the bound class, which restores all unbound fields and properties. Therefore, only the first bound object can get the modified data, and after it completes the refresh operation, it restores all the changes and thus cancels the modifications of other controls, so binding is useless. "
At this point, the study on ".NET 2.0 data binding problem Analysis" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
