Dear All,

I am new in C# windows programming and having issues in handling data of windows forms.

Here is the scenario.

I have created one windows form (named as form1) in which i am taking input via various controls such as text boxes, list boxes, combo boxes and trying to show it in another form , till showing one windows form's input value in second form is working fine but when I try to access values of form1 in third form in order to do some computation based on form1 values I am unable to access them.

Please help me in this scenario that how could access the values of form1 in the third form.

Following is the code that how i am doing this

namespace SmallTestApplication
{
   public partial class Form1 : Form
   {
      public Form1()
      {
         InitializeComponent();
      }

      private void button1_Click(object sender, EventArgs e)
      {
         previewinput dos = new previewinput();
         dos.Show();
         dos.label2.Text = textBox1.Text;
      }

      public string getdataform3()
      {
         Form3 form3obj = new Form3();
         form3obj.getvar = textBox1.Text;
         return form3obj.getvar;
      }
   }
}

namespace SmallTestApplication
{
   public partial class previewinput : Form
   {
      public previewinput()
      {
         InitializeComponent();
      }

      private void button1_Click(object sender, EventArgs e)
      {
         Form3 objform3 = new Form3();
         objform3.Show();
      }
   }
}

namespace SmallTestApplication
{
   public partial class Form3 : Form
   {
      public Form3()
      {
         InitializeComponent();
      }

      public string getvar;

      private void button1_Click(object sender, EventArgs e)
      {
         Form1 objform1 = new Form1();
         MessageBox.Show(objform1.textBox1.Text)
         //MessageBox.Show(objform1.getdataform3());

         //previewinput dos = new previewinput();
         //MessageBox.Show(dos.label2.Text);
      }
   }
}

Thanks,
