Question

i have a windows form in which there are controls listed below
panel1
button1 = add new mobiles
button2 = ok
When clicking on button1 an usercontrol is added. You can add as much userControls as you wish. The userControl defines consists of five controls:

combobox1
combobox2
textbox1
textbox2
textbox3

i want to add the text of textbox3 of all the dynamically generated usercontrol control and set to a label on the winform how can i do that? by clicking the ok button
i have tried this code

foreach (Control ctrl in panel1.Controls)
{
      if (ctrl is UserControl)
      {
           UserControl1 myCrl = ctrl as UserControl1;
           int g;
           // but this doesnt happen an error is coming
           g += Convert.ToInt32(myCrl.textbox3.Text);  
      }
}

how to get sum of all the dynamically generated control’s text

Answer 1

Probably your “error” is that you’re declaring g inside of the foreach loop, so you don’t actually make any sum. Furthermore, you don’t initialize it. Change your code to:

var g = 0;
foreach (Control ctrl in Controls)
{
    if (ctrl is UserControl1)
    {
        var myCrl = ctrl as UserControl1;
        g += Convert.ToInt32(myCrl.textbox2.Text);
    }
}
//Set your label's text
