I am getting the below error when I am loading data from WCF service onDemand.

Microsoft JScript runtime error: 'length' is null or not an object

Any help is appreciated. I beleive it has to do with AJAX.

Thanks

Hello,
 Im finding myself in a dead-end can't understand the issue origin. I explain gradually and post my code blocks if you ask me to.
Using RadScheduler and a new Advanced Form edit template in it for inserting and editing of my appointments, following exactly the pattern as your demo shows (LINK).

My Resources are 3:
- Services    (let's say its the Room from your example)  presented as ResourceControl.ascx (RadComboBox with entries)
- Operators (it's Alex, bob, charly that are able to solve services) as ResourceControl.ascx (another RadComboBox)
- Users ( Only Radscheduler has this one, i don't put this one into AdvancedForm.ascx) i only need this on Session level (login etc)

Mainly it's the Services-Operator couples that defines appointments.

Before describe My issue: i have DayView grouped by Services (like rooms in your case) and once inserted the appointment the drag-n-drop edit is only possible for start/end (vertical only) you can't drag it on another service.

so all i do is controll on Appointment_Update event


this works perfectly.
If i control the resources there're 3 on Appointment and 3 on ModifiedAppointment (Service,Operator and User respectively).
Notice doing so the AdvancedForm is of course not shown

But once the thing Goes on AdvancedForm the resources are LOST !

example: I open already inserted appointment and modify let's say Subject and click Update, if i debug the AdvancedForm.ascx.cs (i put the Update_Button_Click Event to control some things) during that, i see the Appointment object (passed from scheduler to here has it's resources and there're all 3 of them during Update_button_click. After that it goes till MainPage.aspx where scheduler is, and of course till Appointment_Update event. When it goes to IF sentence i wrote before the NullReference happens :

ModifiedAppointment.Resources.GetResourceByType("Service") = null     !!!

if i debug this , i see the original Appointment still has 3 resources (Service, Operator, User)
BUT then modifiedAppointment has ONLY 1 (User)

It's as the Binding inside AdvancedForm the Two of my resources (Service and Operator) they're being sucked away by AdvancedForm or being forgot to add inside ModifiedApointment or else ... 

i debugged deeply inside all events of AdvancedForm.ascx.cs and haven't found any remove or loss of these resources, but as soon as the code goes to main page to scheduler events , the modifiedAppointment has 2 (binded) resources lost.

I'm in jeopardy, please help me  >_<

Hi

Hi! I have a grid which has binaryimagecolumn which binds data in sql db. My problem is I still can't display the image correctly in the grid, even if the object which corresponds into the binaryimagecolumn has a byte[] type in c# and image type in sql database.

markup:

<

 

telerik:GridBinaryImageColumn DataField="PictureImg" HeaderText="Image" UniqueName="PictureImg"

 

 

ImageAlign="Middle" ImageHeight="200px" ImageWidth="200px" ResizeMode="Fit">

 

 

<HeaderStyle Width="10%" />

codebehind:

 

 

protected class PictureTemplate

 

 

 

 

{

 

public Guid PictureID { get; set; }

 

 

public string PictureName { get; set; }

 

 

public byte[] PictureImg { get; set; }

 

 

public string PictureDesc { get; set; }

 

}

 

protected void RadGrid1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

 

{

 

List<PictureTemplate> picTemplate;

 

 

using (DianaOnlinePhotoEntities db = new DianaOnlinePhotoEntities())

 

{

picTemplate = (

from p in db.tblPicture

 

 

where p.PictureID != null

 

 

select new PictureTemplate

 

{

PictureID = p.PictureID,

PictureName = p.PictureName,

PictureImg = p.PictureImg,

PictureDesc = p.PictureDesc

}).ToList();

RadGrid1.DataSource = picTemplate;

}

}

Hope I can fix the problem, Thanks!!

I am trying to retrieve the filter client-side to pass to a dialog window being displayed.  I am calling the get_filterExpression() method on the MasterTableView but an empty string is being returned.  Is this a bug or does it require something special.

function GetFilterData() {

var filterString = "";

var filter = $find(GridMasterView).get_filterExpressions();

for (var i = 0; i < filter.length; i++)

filterString += filter[i].get_columnUniqueName() + "~" + expression.get_fieldValue() + "~";

return filterString;

}

Please let me know how I can accomplish this.

Thanks

Subject:  How can I call the server code from RadContextMenu Item Selecting?

1. I have list of appointments populated in the Scheduler which binds from the database in page load event.

2. I need the following

a) Right click on the appointments.

b) Show the context menu.

c) click an item from context menu , how can I call the codebehind function (RadScheduler1_AppointmentUpdate or SchedulerContextMenu_ItemClick)?. How can I get the selected appointmentsvalue like (Subject Id, Start/End Date)?

Note:

      1. Create a context menu item as “Waitinglist”.

2. Select the “Waiting list” from the menu.

3. Update selected appointments in the Database.

Thanks and Regards

I have a GridButtonColumn and I'm wondering if it's possible to call a method in my C# code-behind.

I have this GridButtonColumn and I tried to set the OnDeleteCommand to call my method but it's not firing.


Delete Method I wish to call:

Is it at all possible to get this method to run after the user confirms the delete message button?

Hi,
I don't understand how to group my appointments. :(
For example:
If I have one appointment that occurs 10 times (recurrence), I want these 10 to render on the same row, horizontaly.
And next appointment (if exists) it will render below, and so on.
How do I make the group by?

My first thought was to group by RecurrenceParentID but that doesn't seems to work.
With this code the timeline is just blank! No appointments showing!

I have a project that was developed somewhere else that I am trying to set up for development. I copied the entire source and am getting this error.

Server Error in '/' Application.

Parser Error

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: Unknown server tag 'telerik:RadPanelBar'.

Source Error:

Line 2: Inherits="WebControls_UserLeftMenu" %> Line 3: <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> Line 4: <telerik:RadPanelBar Width="169px" ID="RadPanelBar1" runat="server" ExpandMode="SingleExpandedItem" Line 5: Skin="Web20" > Line 6: <Items>

it says it is an unknown server tag but as you can see it is registered right before the tag. Does anyone know what the problem is. Here is the ascx page the error is in. Line 4



And here is the web.config file

Is this possible?  I've been trying to a few hours to figure it out, but can't find a way.
