Appointments.FindByID not work with RadToolTipManager OnAjaxUpdate

I'm trying to show appointments in TimeLineView grouped by resources. For each appointment in RadScheduler, I want to display dynamic tooltip. For that I had used RadToolTipManager and OnAjaxUpdate.

Code Snippet -

protected void RadToolTipManager1_AjaxUpdate(object sender, ToolTipUpdateEventArgs e)

{

// THIS WORKS SUCCESSFULLY

Appointment appointment = null;

foreach (var apt in EventScheduler.Appointments.Where(apt => apt.ID.ToString().Equals(e.Value)))

{

appointment = apt;

break;

}

// CODE COMMENTED BELOW NOT WORKS. WHY?

//int aptId;

//var appointment = int.TryParse(e.Value, out aptId) ? EventScheduler.Appointments.FindByID(aptId) : EventScheduler.Appointments.FindByID(e.Value);

if (appointment == null) return;

var toolTip = (AppointmentToolTip)LoadControl("UserControl/AppointmentToolTip.ascx");

toolTip.TargetAppointment = appointment;

e.UpdatePanel.ContentTemplateContainer.Controls.Add(toolTip);

}

I am seeking answer to why part in code comment. If it work one way, then it must work another way. Did anyone else noticed this bug?

I believe that the commented part is more optimized and fast in comparison to method I had implemented. So can Telerik team confirm that code I'm using would be equivalent fast?

Viewing all past entries in RadGrid

Hello,

I have a Grid now that is updated once a day with changes on various status' from my users. My question is, does anyone have any ideas on how to save those previous entries to an archive that the user can go into and view previous entries?

The goal would be to have this archive and then after a certain point those archived entries would be deleted to avoid taking up too much database room unnecessarily.

Right now here is how I am saving my grid to my database, I just wasn't sure on how to expand on this to get that additional functionality.

private void SaveDataInDataTable()

{

foreach (GridDataItem item in RadGrid1.MasterTableView.Items)

{

if (item.IsInEditMode)

{

int rowID = (int)item.GetDataKeyValue("ID");

for (int i = 2; i < RadGrid1.MasterTableView.RenderColumns.Length; i++)

{

GridColumn column = RadGrid1.MasterTableView.RenderColumns[i];

DataRow myDataRow = GridSource.Select("ID = " + rowID)[0];

object value = GetColumnValue(column, item);

if (column.DataType == typeof(int))

{

if (value == string.Empty || value == null)

{

myDataRow[column.UniqueName] = DBNull.Value;

}

else

{

int parsedValue;

if (int.TryParse(value.ToString(), out parsedValue))

{

myDataRow[column.UniqueName] = parsedValue;

}

else

{

myDataRow[column.UniqueName] = myDataRow[column.UniqueName];

RadAjaxManager1.Alert(string.Format("Value {0} is not valid for column {1}, row {2}. The old value was used!", value, column.UniqueName, item.ItemIndex+1));

}

else if (value == null)

{

myDataRow[column.UniqueName] = DBNull.Value;

}

else if

((GridSource.Columns[column.UniqueName].MaxLength < value.ToString().Length) && GridSource.Columns[column.UniqueName].MaxLength != -1)

{

myDataRow[column.UniqueName] = value.ToString().Substring(0, 5);

}

else

{

myDataRow[column.UniqueName] = GetColumnValue(column, item);

}

Elegant solution for RadDateTimePickers?

I have an app where the user selects a From Date/Time and a To Date/Time. The default time on the End needs to be 23:59. Consider that if the user selects the same date in both controls that they intend to mean the entire day, not 12am to 12am of the same day. And it's a bit much to ask them to select the next day so that they get 12am of the next day.

So we're looking for a default of:
From 12/12/2013 00:00 to 12/12/2013 23:59

How do I set that? For the RadDateTimePicker, if I use markup to set the DateInput SelectedDate to "23:59", assuming the current date will get substituted, it still defaults to current date 00:00. Anything I set there is not used, like SelectedDate="01/01/2014 06:00AM". I know the default value for DateInput is MinDate, but I don't want to set a MinDate of "from date 23:59" because that will preclude setting to an earlier time of day.

Also, assume the user selects 21:00 but then they really want to change it to "end of day". Do I need to create a custom list in the TimeView which will allow them to select various times, including a final 23:59?

Rather than trying to accommodate such nuances, I'm wondering if there is a better solution. For example, I can code some post-processing logic that says "if the start and end-time are both 00:00 of the same day, then make the To time 23:59" for subsequent queries, or we can simply not use the time component if the date and tie are the same and the time is 00:00.

Thanks for your consideration. And I hope this help someone else who is working out a From/To scenario.
