Question

I have a list box control which I am filling from the page’s code behind.

It works with values from 1 to 100, but what if the range I need gets really large? (For example, 1 to 200000000?)

Currently I am using this:

<asp:ListBox ID="ListBox1" runat="server" EnableTheming="True" 
 Height="20px" Width="54px">

</asp:ListBox>

And in my code behind:

for (int i = 0; i < 100; i++)
{
    ListBox1.Items.Add(i.ToString());
}

What is the correct way to approach this problem?

Answer 1

You could use the NumericUpDown tool from the AJAX toolkit. It lets you enter numbers as well as scroll up and down, without having a varying scrollbar.
