you need to store that selected vlaue in to Session Variable so that you can get the vaue from another page,
and make sure that whenever you dont required that session remove that

If you want to select single record then follow below code:

Session("SeleVal") = ListBox1.SelectedValue

or If you want to multiple selection then follow below code:

Dim x As String = String.Empty

Try

For Each drv As System.Data.DataRowView In Me.ListBox1.SelectedItems

x &= drv.Item(0).ToString & ","

End Try

For that first you have to create a public property on Form2 which represent your textbox's Text property like this.

public string MyProperty

{

get{ return txtMyProperty.Text; }

set{ txtMyProperty.Text = value;}

}

Reason to do this is that you can't directly access the TextBox of Form2 on Form1 becuase it is defined as private.

Now on form1, in list's selected indexchanged you can set that property value of Form2 like this

private void listBox_SelectedIndexChanged(object sender, EventArgs e)

{

form2.MyProperty = listBox.SelectedText;

}
