Passing value from one form to another

Question

Passing the listBox1.SelectedItem value from one form to another?
The output for the listBox1.SelectedItem in Form1 is a path (eg: "E:\\New Files")
Now Form2 basically contains the code for an application. I want to use the output of this selectedItem in Form2.
Please help me as I am very new to C#.
Thank you in advance

hi you can use constructor to pass value from one page to another page if you are working with windowbase application. public Form2(int mydata) { // do some thing... } private void button1_Click(object sender EventArgs e) { int data = 5; Form2 f = new Form2(data); f.show(); } you can use any state Management technique like viewstate session Query string etc if you are working on web base application hope this will help you.

First of all change the Modifiers property of listBox1 from private to internal so it will be visible to other forms in the application. You then need to get a reference to Form1: Form1 f1 = (Form1)Application.OpenForms[Form1]; string item = ; if (f1.listBox1.SelectedIndex > -1) { item = f1.listBox1.SelectedItem.ToString(); }
