HtmlTextBox server side binding

[Pablo Tola]

When I try to bind an HtmlTextBox server side no data is displayed on the report, I don't know when this stopped working because a client of mine just reported it happening after my last update to his system using the latest telerik Reporting build. This was working fine before that.

Here's the code, I can't find anything wrong with it.

private void GetAppointments()
{

    StartDate = new DateTime(2008, 10, 1);
    EndDate = new DateTime(2008, 11, 1);
    MemberId = 10;
    Priority = null;
    Color = null;
    EmployeeId = null;

    appointments = (from a in _context.Appointment
                    where a.Start >= StartDate &&
                        a.End < EndDate &&
                        a.WorkOrderId > 0 &&
                        (a.MemberId.Equals(MemberId) || MemberId == null) &&
                        (a.WorkOrder.Job.Priority.Equals(Priority) || Priority == null) &&
                        (a.Color.Equals(Color) || Color == null) &&
                        (a.WorkOrder.WorkOrderResourceList.Select(r => (long?)r.EmployeeId).ToList().Contains(EmployeeId) || EmployeeId == null)
                    orderby a.Start
                    select a).ToList();

}

void Schedule_NeedDataSource(object sender, EventArgs e)
{

    GetAppointments();
    tblAppointments.DataSource = appointments;

}

void htmlWorkOrdeDetails_ItemDataBound(object sender, EventArgs e)
{
    Telerik.Reporting.Processing.HtmlTextBox details = (Telerik.Reporting.Processing.HtmlTextBox)sender;

    var workOrder = details.DataObject["WorkOrder"] as Entities.WorkOrder;
    var color = (AppointmentColor)details.DataObject["ColorAppointmentColor"];
    var subject = (string)details.DataObject["Subject"];

    var workOrderDetails = new System.Text.StringBuilder();
    if (workOrder != null)
    {
        var job = workOrder.Job;
        var jobSite = job.Address;
        var customer = job.Customer;

        var resources = string.Empty;

        switch (workOrder.AssignedToType)
        {
            case 0:
                resources = "Not Assigned";
                break;
            case 1:
                resources = string.Join(", ", workOrder.WorkOrderResourceList.Select(r => (r.Employee.FirstName + " " + r.Employee.LastName)).ToArray());
                break;
            case 2:
                resources = workOrder.AssignedToContractor.Name;
                break;
        }

        workOrderDetails.Append("<div style='background-color: white'>");
        workOrderDetails.AppendFormat("<b>Work Order # {0}</b><br/>", workOrder.Number);
        workOrderDetails.AppendFormat("<b>Job Site:</b> {0}, {1}, {2}. {3}<br/>", HttpUtility.HtmlEncode(jobSite.AddressMember), HttpUtility.HtmlEncode(jobSite.City.Name), jobSite.State.Abbreviation, jobSite.ZipCode.ZipCodeMember);
        workOrderDetails.AppendFormat("<b>Customer:</b> {0}<br/>",HttpUtility.HtmlEncode(customer.Name));
        workOrderDetails.AppendFormat("<b>Job Name:</b> {0}<br/>", HttpUtility.HtmlEncode(job.Name));
        workOrderDetails.AppendFormat("<b>Assigned To:</b> {0}<br/>", HttpUtility.HtmlEncode(resources));
        workOrderDetails.AppendFormat("<b>Notes:</b> {0}", string.IsNullOrEmpty(subject) ? "N/A" : HttpUtility.HtmlEncode(subject));
        workOrderDetails.Append("</div>");
    }

    details.Style.BorderWidth.Default = new Unit(1);
    details.Style.BorderColor.Default = ColorTranslator.FromHtml(color.Name);
    details.Style.BackgroundColor = ColorTranslator.FromHtml(color.Name);
    details.Value = workOrderDetails.ToString();
}

Hello Pablo Tola,

You should be using the ItemDataBinding event instead for such purposes, because the ItemDataBound is fired just after the item is bound to data. Although this used to work in previous versions, it was wrong, and the new behavior is the expected one.

Uhm.... so what is the purpose of ItemDataBound event, if I can't modify the databound item?

Best Regards.
