I'm developing software that every time the user clicks the save button, he needs to add +1 to a TextBox .
Ex: Box = 1 - > Save - > Box = 2.
Every time the user clicks save , he has to change the box number, always adding 1. I tried to count in TextBox and convert the value to% with% after add a count but did not pay.
Why a string ? Because my user will always need to enter the initial value of the last box that he closed.
Ex: The day ended in 32 Box, the next day he needs to set to box 33, from there every time he starts clicking save , he would add 1.
private void textBox44_TextChanged(object sender, EventArgs e)
{
int valor = Convert.ToInt32(textBox44);
valor = valor++;
}
