hello perumal, I am having label1 in FORM2. I have to display the value ID(integer) local variable in FORM1 to the label1 in FORM2.

Solution 1

Create a property on Form 2

C#

public string LblText
   {

           set { lable.text = value ;}
   }

and set value to this property from Form1 (before show dialog)

do you want to set label value before form 2 is called or after?

After form 2 is called i want to set value for the label(form 2) from the local variable ID(form 1). The data type is int.

Solution 4

C#

public Int  kmp=0;
 private void Button_Click(object sender, EventArgs e)
        {
kmp=ur value;
           Form2 qu = new Form2 ();
            qu.ShowDialog();
}

C#

private void Form2_Load(object sender, EventArgs e)
        {
           Form1 l = new Form1();
          label1.text=  l.kmp.toString() ;
        }

Or

C#

private void Button_Click(object sender, EventArgs e)
        {

           Form2 qu = new Form2 (ur value);
            qu.ShowDialog();
}

C#

public Form2(int l)
       {
           InitializeComponent();
 label1.text=l.toString();
       }
