Question

I got a main button function, where i parse the textbox text values, then I pass those values to an another method.
After performing the first calculation, then i want to pass those parameters to another button function.

I want to assign int valueOF1, int valueOF2to this method public void testfunction(object sender, EventArgs ea) from the main button.

How can i do this?? Thank you for your help.

This is the code:

private void b_calculate_Click(object sender, EventArgs e)
    {

        int valueOF1;
        int.TryParse(t_Offset1.Text, NumberStyles.Any,
                     CultureInfo.InvariantCulture.NumberFormat, out valueOF1);

        int valueOF2;
        int.TryParse(t_Offset2.Text, NumberStyles.Any,
                     CultureInfo.InvariantCulture.NumberFormat, out valueOF2);

        int pRows = PrimaryRadGridView.Rows.Count;
        int sRows = SecondaryRadGridView.Rows.Count;

        if (pRows == 1 && sRows == 1)
        {
            calculatePS(valueOF1, valueOF2);
        }


}

private void calculatePS(int valueOF1, int valueOF2)
{
    MessageBox.Show("You are using : P-S");
    // Do some calculation & go to the next function ///
    Button2.Enabled = true;
    Button2.Click += testfunction; // Here i want to pass the valueOF1 & valueOF2

}

public void testfunction(object sender, EventArgs ea)
{
    MessageBox.Show("you...!");
    Button2.Enabled = false;
}

You can declare valueOF1 and valueOF2 as class fields, so you can access them from different methods.

Here’s how the code could look like:

int valueOF1 = 0;
int valueOF2 = 0;

private void b_calculate_Click(object sender, EventArgs e)
{
    int.TryParse(t_Offset1.Text, NumberStyles.Any,
                 CultureInfo.InvariantCulture.NumberFormat, out valueOF1);

    int.TryParse(t_Offset2.Text, NumberStyles.Any,
                 CultureInfo.InvariantCulture.NumberFormat, out valueOF2);

    int pRows = PrimaryRadGridView.Rows.Count;
    int sRows = SecondaryRadGridView.Rows.Count;

    if (pRows == 1 && sRows == 1)
    {
        calculatePS();
    }
}

private void calculatePS()
{
    // ** you can use valueOF1 and valueOF2 here **

    MessageBox.Show("You are using : P-S");
    // Do some calculation & go to the next function ///
    Button2.Enabled = true;

    //probably no need to register the Button2.Click event handler
    //except when the form is created
    //
    //Button2.Click += testfunction; 
}

public void testfunction(object sender, EventArgs ea)
{
    // ** you can use valueOF1 and valueOF2 here as well **

    MessageBox.Show("you...!");
    Button2.Enabled = false;
}

Additional Note: int.TryParse returns a bool value that tells you whether the parse succeeded. In case the return is false, you may want to handle the parse error somehow instead of continuing with the normal flow.
