Scheduler Advanced Form Javascript Error

Hi All,,,,
i am using the Rad Scheduler control on AdvancedForm Templates and user controls as from the demo....

i am using it inside RadPanel like the First Look demo in th follwoing link http://demos.telerik.com/aspnet-ajax/scheduler/examples/outlook2007/defaultcs.aspx

but i changed it to use the user controls instead of the built in advanced form to customize it as i need....

the advanced form in the edit mode is called properly,,, but when i try to call it in the insert mode either by double click the scheduler or from the options button from the inline form; i got the following error:-

Error: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.

i don't not know what is causing this error and i docnt want to disable the ajax since i don't want the page to post back!!!!

any help please....

thanks....

But i want it to stay at the position of the line i selected.

protected void Page_Load(object sender, EventArgs e)
{}

public void RadGridLegalEntities_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
{
List<OM.LegalEntity> entities = new DA.LegalEntity().GetLegalEntities();
RadGridLegalEntities.DataSource = entities;
}

<telerik:RadGrid ID="RadGridLegalEntities" runat="server" AllowSorting="True" AutoGenerateColumns="False" GridLines="None" Skin="Office2007"OnNeedDataSource="RadGridLegalEntities_NeedDataSource" Width=95% Height="465px"

[Solved] Appointment is invalid: Start time must be before the End time.

Hello,

I'm trying to catch this error. If you put a end datetime in that is before the start datetime my application is falling over. Obviously, I am doing this deliberately to break it, but want to catch the error in case a hapless user tries to do the same for some bizarre reason.

I insert my appointments via a custom Insert template using the Scheduler_AppointmentCommand event. I can catch the input here with:

    
            try 
        
                                        { 
        
                                            if (eventEnd >= eventStart) 
        
                                            { 
        
                                                UserEventHelper.ArrangeAppraisal(doctor, eventStart, location, label, eventEnd, user.ID); 
        
                                                litStatus.Text = string.Empty; 
        
                                            } 
        
                                            else 
        
                                            {

So, I am not creating an appointment in my business object if the end datetime occurs before the start datetime, but an error is still thrown from the control. Where do I catch this error? Here is the stack trace if that helps:

[Exception: Appointment is invalid: Start time must be before the End time.]
   Telerik.Web.UI.Appointment.Validate() +162
   Telerik.Web.UI.Scheduling.AppointmentController.InsertAppointmentThroughProvider(Appointment appointment) +17
   Telerik.Web.UI.RadScheduler.InsertAppointmentInline() +106
   Telerik.Web.UI.RadScheduler.OnBubbleEvent(Object source, EventArgs args) +326
   System.Web.UI.Control.RaiseBubbleEvent(Object source, EventArgs args) +37
   System.Web.UI.WebControls.ImageButton.OnCommand(CommandEventArgs e) +111
   System.Web.UI.WebControls.ImageButton.RaisePostBackEvent(String eventArgument) +176
   System.Web.UI.WebControls.ImageButton.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +10
   System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13
   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +36
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565

Apply mixed font color in one event

Hi,

I'd like to know if there is an option to apply mixed font color in the same event in the scheduler.

For example, if the event states: "Meeting with DR. Monroe"

have "Meeting with" colored in blue and "Dr. Monroe" in red.

Thanks!

RadComboBox vertical align in IE

Dear Guru's,

New here and I've been trying to implement the radcombobox to replace a lot of my current listboxes. That all seemed to go quite well, but I ran into an issue that I can't seem to solve with either documentation, google or this forum.

Our webapplication is used in multiple large companies and it should work under any browser the client chooses to use. I found out that the vertical alignment of the text in IE is lower than in, for example Google Chrome. I can't seem to figure out how to resolve this.

Please see that attached image for an example. It's the exact same page, left is IE, right is Chrome. I used the "j" because you can clearly see the difference at the bottom.

Thank you for your time!

Best regards,

-Rem

Open HeaderContextMenu on left click

Hi,

I want to be able to open the RadGrid headercontextmenu on left click instead of right. Currently when I left click, it just changes the sorting, but the sorting can already be accomplished in the context menu. This is the same issue as this thread: https://www.telerik.com/forums/how-to-show-the-radgrid-context-menu-on-left-click-instead-of-right-click but that was a while ago and currently when I implement, the context menu flashes but then disappears. Is there anyway to achieve the appropriate functionality? Here is my code that implements it:

<script type="text/javascript">

function OnColumnClick(sender, args){

args.get_gridColumn().showHeaderMenu(args.domEvent);

}

</script>

… In the RadGrid …

<ClientEvents OnColumnClick="OnColumnClick" />

Line Series showing only markers

I'm currently updating a chart from asp.net chart to telerik htmlchart.

I have a line series chart and for one of the series I would like to add a +/- range at each marker to replicate an ErrorBar series from traditional .net chart control.

If I set the + and - line series as having Fillstyle.BackgroundColor as transparent (hide the line) and set the MarkersAppearance.BackgroundColor to black, I was hoping that the marker appearance would overwrite the series color and display only the marker. however this is not working as the fillstyle appears to be the master.

Is there any way of showing only the marker or will I have to re-write and go with a scatter and scatterline chart? Is there any equivalent to the ErrorBar type?

Thanks in advance.
