I am trying to set a TextBox in a WindowsForm to display the value of the field in currency format. I can only make this happen in the Enter event of the field with the following code:
private void valorTextBox_Enter(object sender, EventArgs e)
{
TextBox txt = (TextBox)sender;
txt.Text = double.Parse(valorTextBox.Text).ToString("C2");
}
How do I make this happen in the Form_Load event and in the navigation of the records?
Create a método :
public void ToMoney(TextBox text, string format = "C2")
{
double value;
if (double.TryParse(text.Text, out value))
{
text.Text = value.ToString(format);
}
else
{
text.Text = "0,00";
}
}
and Form_Load :
private void Form1_Load(object sender, EventArgs e)
{
ToMoney(textBox1, "N2");
}
Where to call in the navigation method, check the componente (or code) where you have a method that indicates that there was a navigation event, if you put it in your question, I can tell you where to call
Note: Your code had a problem, it does not check if the value is a number and this can cause errors.
You could also create an extension method following this class:
public static class TextMoney
{
public static void ToMoney(this TextBox text, string format = "C2")
{
double value;
if (double.TryParse(text.Text, out value))
{
text.Text = value.ToString(format);
}
else
{
text.Text = "0,00";
}
}
}
and Form_Load simplifying:
private void Form1_Load(object sender, EventArgs e)
{
textBox1.ToMoney();
ou //textBox1.ToMoney("N2");
}
