Hi All,

Already i have declared array size.

for (int i = 0; i <= listBox1.SelectedItems.Count; i++)
{
txtmessage.Text = ((DataRowView)listBox1.SelectedItem).Row.ItemArray[i].ToString();
}

Hello,

You have to subtract one from the count, because 0 to 19 = 20 counts

string[] ItemArray = new string[20];
for (int i = 0; i <= listBox1.SelectedItems.Count - 1; i++)
{
txtmessage.Text = ((DataRowView)listBox1.SelectedItem).Row.ItemArray[i].ToString();
}

Thanks,

Anish,

What is the relationship between the listbox1, ItemArray and the DataView?
