Rendering Step 1 of … (ASP.NET)

The MultiView control, Wizard control or even a custom panel-based control is very useful to collect large sets of data in wizard form; and it’s often useful to give visual ques to the user as to which step he/she is in. Something similar to:

The following ASP.NET code/C# allows us to build a dynamic step control which grows or shrinks automatically given the number of views you have in a MultiView control, or the number of steps in a wizard control.

 <asp:Repeater ID="StepMarker" runat="server">
            <headerTemplate>
                <div class="steps">
                    <h2>Step</h2>
                    <ol>
            </headerTemplate>
            <itemTemplate>
                <li<%#ReportingPanel.ActiveViewIndex==Int16.Parse(DataBinder.Eval(Container, "ItemIndex").ToString())?" class=\"active\"":""%>><%#Int16.Parse(DataBinder.Eval(Container, "ItemIndex").ToString())+1%></li>
            </itemTemplate>
            <footerTemplate>
                </ol>
                </div>
                <br style="clear:both" />
            </footerTemplate>
        </asp:Repeater>

 /* if we have arrived at the last step we no longer need to display the step markers */
if (ReportingPanel.ActiveViewIndex + 1 == ReportingPanel.Views.Count) {
	StepMarker.Visible = false;
}
else {
	StepMarker.Visible = true;
	int[] i = new int[ReportingPanel.Views.Count - 1];
	StepMarker.DataSource = i;
	StepMarker.DataBind();
}
