Hi jcad,

use FindControl to get refence of the WebMonthCalendar

 <ig:WebExplorerBar ID="WebExplorerBar1" runat="server" Width="250px" GroupContentsHeight="">
        <Groups>
            <ig:ExplorerBarGroup GroupContentsHeight="" Text="Group">
                <Items>
                    <ig:ExplorerBarItem>
                        <Template>
                            <ig:WebMonthCalendar ID="WebMonthCalendar1" runat="server">
                                <ClientEvents Initialize="WebMonthCalendar1_Initialize" />
                            </ig:WebMonthCalendar>
                        </Template>
                    </ig:ExplorerBarItem>
                </Items>
            </ig:ExplorerBarGroup>
            <ig:ExplorerBarGroup GroupContentsHeight="" Text="Group">
            </ig:ExplorerBarGroup>
        </Groups>
    </ig:WebExplorerBar>

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        DateTime dt = DateTime.Now;
        DateTime startDate = DateTimeHelper.StartOfWeek(dt, DayOfWeek.Monday);
        DateTime endDate = DateTimeHelper.EndOfWeek(dt, DayOfWeek.Sunday);
        WebMonthCalendar wmc = (WebMonthCalendar)WebExplorerBar1.Groups[0].Items[0].FindControl("WebMonthCalendar1");

        wmc.SelectedDates.RangeMin = startDate;
        wmc.SelectedDates.RangeMax = endDate;
    }
}
public static class DateTimeHelper
{

    public static DateTime StartOfWeek(this DateTime dt, DayOfWeek startOfWeek)
    {
        int diff = dt.DayOfWeek - startOfWeek;
        if (diff < 0)
        {
            diff += 7;

        }

        return dt.AddDays(-1 * diff).Date;
    }

    public static DateTime EndOfWeek(this DateTime dt, DayOfWeek endOfWeek)
    {
        int diff = endOfWeek - dt.DayOfWeek;
        if (diff < 0)
        {
            diff += 7;
        }
        return dt.AddDays(diff).Date;
    }
}

 

I suspect the problem might have been caused by trying to use the calendar control (within a webexplorerbar) in a pop-up dialog. Although this worked fine with the old WebCalendar, I understand it is not best practice to have anything interactive in a dialog. EIther way we are now working through our application replacing the pop-up dialogs with having the webdatepicker on the original page.

Regards.

What's happen when it is inside WebExplorerBar, it should be working in the same way?

Thanks but I think the problem is due to the control needing to be in webpanel in order for it to update. I now have it working properly in a webpanel. However I want to avoid using a webpanel with it being an "old (non 11.2) control. Should I be able to use it within a WebExplorerBar (as per the one on one replacement guide?) Does anyone have an example of it being used this way?
