Hi,

i am able 2 add data from 1 listbox 2 another on selectedindexchange but alert message of "itm already exists" is not occuring. And d elements r being added more dan 1nce. Also, if i dnt want to use array and solve the problem by using "Contains" keyword..it is not accepting:

int j;
Boolean flag = true;
//if(!ListBox1.Items.Contains(ListBox2.SelectedItem.Text))
for (j = 0; j <= ListBox1.Items.Count - 1; j++)
{
if (ListBox2.SelectedItem.Text!= ListBox1.Items[j].Text)
{
flag = true;
}
else
{
flag = false;

}
}
if (flag == true)
{
ListBox1.Items.Add(ListBox2.SelectedItem.Text);
//ListBox2.Items.Remove(ListBox2.SelectedItem.Text);
}
else
{
Response.Write("item alrdy exists");
}
}

Just Try this and let me know.........

if (ListBox2.Items.Contains(ListBox1.SelectedItem))
{
Response.Write("Items are there");
}
else
{
ListBox2.Items.Add(ListBox1.SelectedValue);
}
