Wrapping a list vertically with ASP.NET using a repeater for generation

Question

Wrapping a list vertically with ASP.NET using a repeater for generation

I have a repeater that is creating a list of links in no particular order. I want the list to be displayed as follows:

-Item1 -Item4
-Item2 -Item5
-Item3

Most solutions I've found require you to know the items in advance and set specific classes for where the list should break. However, my list can range from 1 to 18 items.

My question is, what is a good, simple way to format a dynamically generated list using an ASP.NET repeater control so that it wraps vertically?

Here's a suggestion for tackling this challenge. Let's assume that the number of items to display vertically before wrapping can be predetermined by the server, rather than being dependent on the user's browser height.

<script runat="server">
    void Page_Load(object sender, EventArgs e)
    {
        rptVerticalWrap.DataSource = new[] {
            new { ID = 1, Name = "ABC" },
            new { ID = 2, Name = "BCD" },
            new { ID = 3, Name = "CDE" },
            new { ID = 4, Name = "DEF" },
            new { ID = 5, Name = "EFG" },
            new { ID = 6, Name = "FGH" },
            new { ID = 7, Name = "GHI" },
            new { ID = 8, Name = "HIJ" },
        };
        rptVerticalWrap.DataBind(); 
    }

    int count;
    const int VerticalWrapLimit = 5;
</script>

    <div style="float:left;">
            <asp:Repeater ID="rptVerticalWrap" runat="server">
                <ItemTemplate>
                    <%
                        if (count % VerticalWrapLimit == 0 && count > 0)
                        {
                            %></div><div style="float:left;"><%                     
                        }
                        count++;
                    %>
                    <div>
                        <asp:Label runat="server" Text="ID: " /><asp:TextBox runat="server" Text='<%# Eval("ID") %>' />
                        <asp:Label runat="server" Text="Name: " /><asp:TextBox runat="server" Text='<%# Eval("Name") %>' />
                    </div>
                </ItemTemplate>
            </asp:Repeater>
    </div>
    </div>
    </form>
</body>
</html>

In approaching a problem like this, it's important to envision the desired HTML structure first and then craft the ASP code to generate it accordingly.

In this scenario, each vertical column of data is enclosed in a div element with the style attribute set to "float:left;". The use of a class-scoped "count" variable helps in determining when to close off the current div and initiate a new one. It should be noted that the count variable must be declared at the class level due to scope differences within the Repeater's ItemTemplate compared to the rest of the page.
