How can I create a link between text boxes using C# or C++?

Question

How can I create a link between text boxes? I am working on my Accounting Project in which I have to link the multiple sheets and their data.

I am using multiple panels on a single from and there are many simple text boxes on my panels so the main thing I want here is that if I made change in one textbox it automatically updates the value of other textboxes linked with that.

Assume there are 4 textboxes. You can bind them as follows:

textBox1.DataBindings.Add("Text", textBox2, "Text", false, DataSourceUpdateMode.OnPropertyChanged);
textBox2.DataBindings.Add("Text", textBox3, "Text", false, DataSourceUpdateMode.OnPropertyChanged);
textBox3.DataBindings.Add("Text", textBox4, "Text", false, DataSourceUpdateMode.OnPropertyChanged);

Now when you change the text in any of them there will be changes in all.

What do you mean automatically updates the value of other textboxes? There are no magic behind, just a code. So what you have to do is write some code. Call event on main text box OnTextChange and after that inside the function something like myTextBox1_OnTextChange() update the other control.
