the regular swithes work fine /qn but the installer launches IE and when deploying via SCCM the installation launches IE.

Reminder Dismiss Event not Firing.

Hello,

I have a radscheduler with a SQL data source provider. I have reminders enabled for our radscheduler and I am having a few problems with the reminders themselves. The first issue is that the reminders never seem to go away even after clicking the dismiss button. After the dismiss button is clicked the reminder will appear every time I return to the page and it never seems to be updated in the Reminders column of the DB. I tried adding some custom code in the ReminderDismiss event, but the event never seems to fire which is my second issue. I have these events set up just like the insert/edit events so to speak. However whenever the reminder dialog appears and I click dismiss I am unable to hit this event. I tried the same thing with the snooze event. It never seems hits the event.

Here is my client side code:

<telerik:RadScheduler ID="RadScheduler1" runat="server" DataEndField="End"

DataKeyField="ID" DataRecurrenceField="RecurrenceRule"

DataRecurrenceParentKeyField="RecurrenceParentID" DataSourceID="SchedulerDataSource"

DataDescriptionField="Description"

Height="700px"

OnAppointmentCommand="RadScheduler1_AppointmentCommand"

StartInsertingInAdvancedForm="true"

Reminders-Enabled="true"

OnReminderSnooze="Reminder_Snooze"

DataReminderField="Reminder"

OnReminderDismiss="RadScheduler1_ReminderDismiss"

StartEditingInAdvancedForm="true"

OnFormCreated="RadScheduler1_FormCreated"

AdvancedForm-EnableCustomAttributeEditing="true"

OnAppointmentInsert="RadScheduler1_Scheduled_EventsInsert"

OnAppointmentUpdate="RadScheduler1_Scheduled_EventsUpdate"

CustomAttributeNames="AssetName, Parameters"

DataStartField="Start" DataSubjectField="Subject" Skin="Sitefinity">

<Localization AdvancedEditAppointment="Edit Event" AdvancedNewAppointment="New Event" />

<AppointmentContextMenuSettings EnableDefault="true" />

<AdvancedForm Modal="true" />

<AppointmentTemplate>

<%# Eval("Subject") %>

<p style="font-style: italic;">

<%# Eval("AssetName")%></p>

<%# Eval("Parameters")%></p>

</AppointmentTemplate>

<TimelineView UserSelectable="false" />

</telerik:RadScheduler>

As you can see set reminders-enabled to true I have my data reminder field and I have set my OnReminderDismiss event.

Here is my server side code:

protected void RadScheduler1_ReminderDismiss(object sender, ReminderDismissEventArgs e)

{

// Lets do some custom code stuff...

e.Cancel = true;

}

Have I missed something really obvious? Is there another property related to reminders that I must set?

Thanks in advance for your help. I do very much like the scheduler tool otherwise.

[Solved] Switch expand/collapse logic.

Hey at Telerik

I would like to know if there's a way to switch the expand/collapse logic of the RadPanelBar regarding the design.

I have a RadPanelBar locked in the middle at the bottom of my page and would like the expand/collapse images (logic) to be switched.

I have tried playing with css for elements

.rpExpandHandle and

.rpCollapseHandle

but with no luck.

Any help would be greatly appreciated.

[Solved] Self-Referencing Hierarchical Radgrid Out of Range Exception ItemHierarchicalIndex

Okay so here is the problem. I have a self-referencing grid that is setup for drag and drop. It takes a row and it can move it up and down and it can make it a child of another row. everything is working fine 99% of the time. Where I run into the issue is when I close the drop down menus that show the children and then try to move a row in the grid. Here's my code:

<script type="text/javascript">

function gridRowDropping(sender, args) {

var targetTable = args.get_targetItemTableView();

if (!targetTable || targetTable.get_owner().get_id() !== sender.get_id()) {

args.set_cancel(true);

}

</script>

<div id="DropUnderWrapper">

<asp:CheckBox ID="IsUnder" runat="server" Text=" Drop Under Parent" />

</div>

<telerik:RadGrid ID="SiteMenuGrid" runat="server"

AutoGenerateColumns="false" AllowMultiRowSelection="false"

OnNeedDataSource="SiteMenuGrid_NeedDataSource"

OnItemCreated="SiteMenuGrid_ItemCreated"

OnRowDrop="SiteMenuGrid_RowDrop">

BR tag removed in LI

Hi,

Referring to the link http://www.ximnet.com.my/upload/br_tag_removed_automatically.swf. Browser is IE (9, 10)

1. It is a list.

2. I try to use Shift-Enter to create a line break in one of the item.

3. The line break is removed by editor.

4. I try to put in BR manually and it is removed as well.

Is there a way to stop the BR tag from being removed?

Thanks.
