I would like to pass int _iD to my button click event. For now, I've passed my value to textbox and use it in button click. Is there anyway to bypass the textbox?
public MifarePasswordForm(int _iD)
{
InitializeComponent();
int iD = _iD;
textBox1.Text += iD;
}
Button click event
private void btnOK_Click(object sender, EventArgs e)
{
byte Oid = Convert.ToByte(textBox1.Text);
}
Make a private property if both methods exist in single class else make public property and use it,
public int nID;
public MifarePasswordForm(int _iD)
{
InitializeComponent();
nID = _iD;
textBox1.Text += iD;
}
Button click event
private void btnOK_Click(object sender, EventArgs e)
{
byte Oid = Convert.ToByte(nID);
}
What you currently do is to make your iD a local variable (that is, in the method/constructor scope):
public MifarePasswordForm(int _iD)
{
InitializeComponent();
int iD = _iD; //here it is, the iD is in the constructor/method scope,
//it cannot be accessed outside of the scope
textBox1.Text += iD;
}
You should make your iD a private field in the class scope rather than in the method scope:
private int iD; //declare here
public MifarePasswordForm(int _iD)
{
InitializeComponent();
iD = _iD; //don't declare here
textBox1.Text += iD;
}
So that you can use it like this:
private void btnOK_Click(object sender, EventArgs e)
{
byte Oid = (byte)iD;
}
You should declare this variable as class level variable:
public class MifarePasswordForm
{
public int iD {get;set;} // or private field
public MifarePasswordForm(int _iD)
{
InitializeComponent();
iD = _iD; // here you don't create, only use
textBox1.Text += iD;
}
private void btnOK_Click(object sender, EventArgs e)
{
//inside this method you can use this variable
byte Oid = Convert.ToByte(iD);
}
//other code
}
Now you can use this variable in any method of this class.
