set_modal() not working on subsequent windows after modal window

Hi there,

I'm working on an app that has a RadWindowManager on a master page. This is used to open some detail windows in a non-modal way, which also updates a count of open windows, which can be re-opened, blah blah blah.

The issue occurs when a modal window is opened (via radopen) from a widget placed on the page, which uses the Master Page's RadWindowManager by design, and the window is set modal via script. The user continues their work, closes the window, and everything's fine.

However, the next time the user opens the detail window, it is now modal, despite being explicitly set to non-modal via set_modal(false). In fact, the window itself reports isModal == false, but is still displayed modally.

The RadWindowManager (on the Master page) is as follows:

<telerik:RadWindowManager ID="rwmRecord" runat="server" Height="500" Width="900"

ShowOnTopWhenMaximized="false" Behaviors="Close,Move,Resize,Maximize,Reload,Minimize"

ReloadOnShow="true" ShowContentDuringLoad="false" VisibleStatusbar="false" EnableShadow="true"

OnClientClose="OnClientClose" OnClientCommand="OnClientCommand">

Any thoughts?

Blocking RadScheduler time slots

Hello.

I have been developing a web application that accesses the database via web service.
In order to block time slots of the RadScheduler component, I have implemented the following method, which is associated with event OnTimeSlotCreated:

protected void RadScheduler1_TimeSlotCreated(object sender, TimeSlotCreatedEventArgs e)

{

// checking if the current time slot is blocked

if (TimeSlotBlocked(e.TimeSlot.Resource.Key.ToString(), e.TimeSlot.Start, e.TimeSlot.End))

{

e.TimeSlot.CssClass = "Disabled";

}

Method TimeSlotBlock checks if the resource is blocked for the start and end times provided:

protected bool TimeSlotBlocked(String pt, DateTime dt1, DateTime dt2)

{

foreach (PTBlockedTime bt in blockedTime)

{

if

((pt == bt.PersonalTrainerId) && ((dt1.AddMinutes(+1) >= bt.Start && dt1.AddMinutes(+1) <= bt.End) || (dt2.AddMinutes(-1) >= bt.Start && dt2.AddMinutes(-1) <= bt.End)))

{

return true;

}

return false;

}

blockedTime is a list of blocked times:

public struct PTBlockedTime

{

public String PersonalTrainerId;

public DateTime Start;

public DateTime End;

public PTBlockedTime(String pt, DateTime dt1, DateTime dt2)

{

PersonalTrainerId = pt;

Start = dt1;

End = dt2;

}

.

List<PTBlockedTime> blockedTime = new List<PTBlockedTime>();

For testing purposes, I have loaded blockedTime on Page_Load:

DateTime aux1 = new DateTime(2012, 1, 25, 8, 0, 0);

DateTime aux2 = new DateTime(2012, 1, 25, 10, 0, 0);

PTBlockedTime aux = new PTBlockedTime("575204", aux1, aux2);

blockedTime.Add(aux);

This list item indicates that resource "575204" is blocked from 08:00 AM to 10:00 AM on 01/25/2012.

This solution works only partially for two reasons:

1) Method TimeSlotCreated is not called when the calendar date changes. Although in the code above the resource is blocked only on 01/25/2012, all dates will have the time slots blocked from 8 to 10.
Is there a way to solve this problem?

2) Instead of Page_Load, the routine that populates the list of blocked times needs to be called every time the calendar date changes. This is required because the time resources are blocked varies on a daily basis. On one day, a resource might be blocked from 8 to 10 AM. On another day, from 5 to 7 AM. And in another day, not blocked at all.
How can the list of blocked times be populated every time the calendar date changes?

Thank you in advance.

Recurring appointment only showing once in my databound scheduler

Hi

I am new to Telerik and I am working with the scheduler and want recurring appointments.
I am using the standard advanced insert and then hooking into the oninsert event and adding them to the database but I am only seeing the appointment once in the scheduler.
I have found in the forum about the \r\n for the new lines and have tried adding this but it doesn't seem to make any difference but can't seem to find anything else.

Can anyone see what I am doing wrong?

I am adding appointments like this:

protected void RadScheduler1_AppointmentInsert(object sender, SchedulerCancelEventArgs e)

{

//add the new appointment to the db

int? recurrentParentId = null;

if (e.Appointment.RecurrenceParentID != null) recurrentParentId = (int)e.Appointment.RecurrenceParentID;

AppointmentManager.AddUserAppointment(

UserId,

1,

e.Appointment.Start,

e.Appointment.End,

e.Appointment.RecurrenceRule,

recurrentParentId,

e.Appointment.Description,

e.Appointment.Subject);

BindSchedule();

}

I am then binding the scheduler like this:

mySchedule.DataSource = GetSchedule(); //calls the database and gets the appointments

mySchedule.DataBind();

This is my scheduler markup is:

<telerik:RadScheduler runat="server" ID="mySchedule" DayStartTime="08:00:00" DayEndTime="22:00:00"

StartInsertingInAdvancedForm="true" ShowNavigationPane="true" OnAppointmentInsert="RadScheduler1_AppointmentInsert"

OnAppointmentUpdate="RadScheduler1_AppointmentUpdate" OnAppointmentDelete="RadScheduler1_AppointmentDelete"

DataKeyField="AppointmentId" DataSubjectField="Subject" DataDescriptionField="Description"

DataStartField="Start" DataEndField="EndX" DataRecurrenceField="RecurrenceRule"

DataRecurrenceParentKeyField="RecurrenceParentId" FirstDayOfWeek="Monday" ShowHeader="true"

ShowFooter="false">

<AdvancedForm Modal="true" />

<DayView UserSelectable="false" />

<WeekView UserSelectable="false" />

<MonthView UserSelectable="false" />

<TimeSlotContextMenuSettings EnableDefault="true" />

<AppointmentContextMenuSettings EnableDefault="true" />

<ResourceTypes>

<telerik:ResourceType KeyField="ID" Name="Type" TextField="Keyword" ForeignKeyField="AppointmentTypeID"

DataSourceID="AppointmentTypesDataSource" />

</ResourceTypes>

<ResourceStyles>

<telerik:ResourceStyleMapping Type="Type" Text="Event" ApplyCssClass="rsCategoryGreen" />

<telerik:ResourceStyleMapping Type="Type" Text="Personal" ApplyCssClass="rsCategoryBlue" />

<telerik:ResourceStyleMapping Type="Type" Text="Meeting" ApplyCssClass="rsCategoryYellow" />

</ResourceStyles>

<AppointmentTemplate>

<div >

<h2>

<%# Eval("Subject") %>

</h2>

<div>

</div>

</AppointmentTemplate>

</telerik:RadScheduler>

Redirecting Parent From RadWindow Code Behind Issue

I am having a hell of a time getting this to work correctly. I have a RadWindow that can be launched from any site on the page (the link resides on a master page) and will bring up a login window.

When the user successfully logins in, the SQL reader will set a variable in session and then once the data reader has closed SHOULD redirect to a page based on what is stored in the session variable.

So I need to be able in my code behind to say If Session("ThisValue") = Something then Close RadWindow and redirect parent.

I have this code in the RadWindow:

<script type="text/javascript">

function RedirectUser(sender, args) {

GetRadWindow().BrowserWindow.location.href = '../ThisPageWhenRedirectUser.aspx';

GetRadWindow().close(); //closes the window

}

function GetRadWindow() //Get reference to window

{

var oWindow = null;

if (window.radWindow)

oWindow = window.radWindow;

else if (window.frameElement.radWindow)

oWindow = window.frameElement.radWindow;

return oWindow;

}

</script>

I just don't know how to call that from my code behind. I am trying it like so:

'after database has retrieved and stored the value in session

If (Session("UserType") = Something Then CloseRadAndRedirect()

Public Sub CloseRadAndRedirect()

If (Not ClientScript.IsStartupScriptRegistered("GetRadWindow")) Then

ScriptManager.RegisterStartupScript(Page, Me.GetType(), "GetRadWindow", "RedirectUser();", True)

End If

End Sub

This does not work. In fact it simply refreshes the radwindow and the controls lose their formatting and styles.

Any help would be greatly appreciated.

The PageRequestManager cannot be initialized more than once."

Assuming assembly reference 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' matches 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35', you may need to supply runtime policy

How to chech the cursion position in rad editor

Hi, i am using rad editor in wysiwyg mode.

I need to insert some text to cursor position.

before paste some text, i need to check some condition like, the given cursor position is center/left/right of the particular elememt.

My code like

var selectedtag = editor.getSelectedElement();

var range = editor.getSelection().getRange();

var selection = editor.getSelection();

if (selectedtag.tagName != "LI" && selectedtag.tagName != "P") {

var sel = editor.getSelection().getText();

var text = selectedtag.innerHTML;

//range.pasteHTML('<p>' + sel + '</p>');

selectedtag.innerHTML = '<p>' + text;

}

else if (selectedtag.tagName == "LI") {

var sel = editor.getSelection().getText();

if (sel == "") {

range.pasteHTML('</li><li>...</li>');

}

else {

range.pasteHTML('</li><li>' + sel + '</li>');

}

else if (selectedtag.tagName == "P") {

var sel = editor.getSelection().getText();

if (sel == "") {

range.pasteHTML('</p><p>');

}

else {

range.pasteHTML('</p><p>' + sel + '</p>');

}

else {

var sel = editor.getSelection().getText();

if (sel == "") {

range.pasteHTML('</p><p>');

}

else {

range.pasteHTML('</p><p>' + sel + '</p><p>');

}

i got the range.
But , how to check if the selected text has any text before and after.

I need to implement some text based on the condition like,

Te Text to the left is empty (ie selection is at the start of the element): <p> selected text text to the right</p>

3) Text to the right is empty (ie selection is at the end of the element): <p>Text to the left selected text </p>

i need the output like,

<p> selected text</p><p>text to the right</p>

How to check if the selected text /range contains any text before and after the selected text.

This is urgent requirement.
Thanks ,

Customize Spell Check Action

I am interested in using Telerik RadSpell client side. My specific need is that I want to be able to control the action performed on the replaced/corrected words. Is there a way to bind to an event that will allow me to custom wrap the corrected word in some additional HTML?
