链接两个文本框，以便在一个文本框中进行更改会导致在另一个文本框中进行更改，反之亦然。

Question

I want to write a simple program in C# that performs conversion from kVA rating to kW rating and calculate Current ratings of a electricity generator at fixed voltage level and PowerFactor.

What the program would do is the user enter value in any of the three textboxes (let say kVA) and the program calculate other two parameters (kW and Current) in respective textbox without pressing any other button.

after that when the user changes the value of other two parameter (say kW) then program would recalculate kVA and Current.

Same with the current textbox.

Answer 1

You need something like this:

On Form Load:

Textbox1.KeyUp += ProcessChange;
Textbox2.KeyUp += ProcessChange;

Then the ProcessChange handler:

private void ProcessChange(object sender, KeyEventArgs ka)
{
   if(sender == Textbox1)
   {
      //do work...
   }

   else //sender==Textbox2
   {
      //do work...
   }
}

This should get you going in the right direction...
