doing validation in other file.cs
-
hi i would like to seperate my design page from validation. so i put the validation code in e.g validate.cs design form
private void textboxInteger_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
validate.txtIntValidate(txtPhone.text)
}in my validate class
class Validate
{
public bool txtIntValidate(string txt)
{
if (!Char.IsDigit(e.KeyChar) && e.KeyChar != (char)8)
{
e.Handled = true; // input is not passed on to the control(TextBox)
}
}
}BUT in the validate.cs class .. how do i declare the e.. Error 3 The name 'e' does not exist in the current context

Good God. e is not present because you have not passed it through. Even if you did, this method should be static, assuming this class should exist at all.

Thank for the reply.. can u pls show some example to get all verification done is the class ? or at least guide me on declaring or passing the e thanks
Passing variables is a fundamental coding practice. How do you think you might want to do it? Here's a clue: The "e" parameter was passed into the function from which you're calling your validation function.
